if the measures of the angles of a triangle are in the ratio of 2:3:5, then the expressions 2x, 3x, and 5x represent the measures of these angles. what are the measures of these angles?

Answers

Answer 1

The measures of the angles of a triangle are in the ratio of 2:3:5, then the actual measures of the angles are 36 degrees, 54 degrees, and 90 degrees.


If the measures of the angles of a triangle are in the ratio of 2:3:5, then the expressions 2x, 3x, and 5x represent the measures of these angles.

To find the actual measures of these angles, we need to use the fact that the sum of the angles in a triangle is always 180 degrees.



Let's say that the measures of the angles are 2y, 3y, and 5y (where y is some constant).

Using the fact that the sum of the angles in a triangle is 180 degrees, we can set up an equation:

2y + 3y + 5y = 180

Simplifying, we get:

10y = 180

Dividing both sides by 10, we get:

y = 18

Now we can substitute y = 18 back into our expressions for the angle measures:

2y = 2(18) = 36

3y = 3(18) = 54

5y = 5(18) = 90

So the measures of the angles are 36 degrees, 54 degrees, and 90 degrees.


Therefore, if the measures of the angles of a triangle are in the ratio of 2:3:5, then the actual measures of the angles are 36 degrees, 54 degrees, and 90 degrees.

Find the perimeter and area of the regular polygon to the nearest tenth.

The perimeter of the regular pentagon is approximately 17.64 feet.

The area of the regular pentagon is approximately 5.708 square feet.

We have,

To find the perimeter and area of a regular polygon with 5 sides and a radius of 3 ft, we can use the formulas for regular polygons.

The perimeter of a regular polygon:

The perimeter (P) of a regular polygon is given by the formula P = ns, where n is the number of sides and s is the length of each side.

In a regular polygon, all sides have the same length.

To find the length of each side, we can use the formula for the apothem (a), which is the distance from the center of the polygon to the midpoint of any side. The apothem can be calculated as:

a = r cos (180° / n), where r is the radius and n is the number of sides.

Substituting the given values:

a = 3 ft x cos(180° / 5)

Using the cosine of 36 degrees (180° / 5 = 36°):

a ≈ 3 ft x cos(36°)

a ≈ 3 ft x 0.809

a ≈ 2.427 ft

Since a regular polygon with 5 sides is a pentagon, the perimeter can be calculated as:

P = 5s

However, we still need to find the length of each side (s).

To find s, we can use the formula s = 2 x a x tan(180° / n), where a is the apothem and n is the number of sides.

Substituting the values:

s = 2 x 2.427 ft x tan(180° / 5)

s ≈ 2 x 2.427 ft x 0.726

s ≈ 3.528 ft

Now we can calculate the perimeter:

P = 5s

P ≈ 5 x 3.528 ft

P ≈ 17.64 ft

Area of a regular polygon:

The area (A) of a regular polygon is given by the formula

A = (1/2)  x n x  s x a, where n is the number of sides, s is the length of each side, and a is the apothem.

Substituting the values:

A = (1/2) x 5 x 3.528 ft x 2.427 ft

A ≈ 5.708 ft²

Therefore,

The perimeter of the regular pentagon is approximately 17.64 feet.

The area of the regular pentagon is approximately 5.708 square feet.

Answers

The logs are written in subscript form to avoid ambiguity in the expressions.

(a) log, 7 + log, 3 = log₂0 x

We can solve the above expression using the following formula:

loga + logb = log(ab)log₂0 x = 1 (Because 20=1)

Therefore,log7 + log3 = log(7 × 3) = log21 (applying the first formula)

Therefore, log21 = log1 + log2+log5 (Because 21 = 1 × 2 × 5)

Therefore, the final expression becomes

log 21 = log 1 + log 2 + log 5(b) log, 5 - log, log, 3²

Here, we use the following formula:

loga - logb = log(a/b)We can further simplify the expression log, 3² = 2log3

Therefore, the expression becomes

log5 - 2log3 = log5/3²(c) logg -- 5log,0 32

Here, we use the following formula:

logb a = logc a / logc b

Therefore, the expression becomes

logg ([tex]2^5[/tex]) - 5logg ([tex]2^5[/tex]) = 0

Therefore, logg ([tex]2^5[/tex]) (1 - 5) = 0

Therefore, logg ([tex]2^5[/tex]) = 0 or logg 32 = 0

Therefore, g^0 = 32Therefore, g = 1

Therefore, the answer is logg 32 = 0, provided g = 1

Answers

Answer:

Since the limit is less than 1, we can conclude that the series converges. Therefore, the given series ∑ [(k!) / (k^2)^k] converges.

Step-by-step explanation:

To determine the convergence or divergence of the series, we will analyze the given series step by step.

The series is given as:

∑ (k=1 to ∞) [(k!) / (k^2)^k]

Let's simplify the terms in the series first:

(k!) / (k^2)^k = (k!) / (k^(2k))

Now, let's apply the ratio test to determine the convergence or divergence of the series.

The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges. If the limit is greater than 1 or it does not exist, then the series diverges.

Let's calculate the limit using the ratio test:

lim (k → ∞) |[(k+1)! / ((k+1)^(2(k+1)))] * [(k^(2k)) / (k!)]|

Simplifying the expression:

lim (k → ∞) |(k+1)! / k!| * |(k^(2k)) / ((k+1)^(2(k+1)))|

The ratio of consecutive factorials simplifies to 1, as the (k+1)! / k! = (k+1), which cancels out.

lim (k → ∞) |(k^(2k)) / ((k+1)^(2(k+1)))|

Now, let's consider the limit of the expression inside the absolute value:

lim (k → ∞) [(k^(2k)) / ((k+1)^(2(k+1)))] = 0

Since the limit of the expression inside the absolute value is 0, the limit of the absolute value of the ratio of consecutive terms is also 0.

Since the limit is less than 1, we can conclude that the series converges.

Therefore, the given series ∑ [(k!) / (k^2)^k] converges.

Answers

The option that is NOT a condition/assumption of the chi-square test for two-way tables is: d. Random sample(s) of individuals that fall into just one cell of the table.

In the chi-square test for two-way tables, it is not required that the sample consists of individuals who fall into just one cell of the table. The chi-square test analyzes the association between two categorical variables in a contingency table. The conditions/assumptions for the chi-square test are:

a. Large enough expected counts: The expected frequency for each cell in the table should be at least 5 or higher. This ensures that the chi-square test statistic follows the chi-square distribution.

b. Normal data or large enough sample size: The chi-square test is based on an asymptotic distribution and works well for large sample sizes. However, it is not dependent on the assumption of normality.

c. None of these options: all three conditions/assumptions are necessary: This is an incorrect option because the assumption of normality is not necessary for the chi-square test. The other two conditions (large enough expected counts and random sample) are indeed necessary for the validity of the test.

Answers

To evaluate the line integral ∫ γ y^2 dz + x^2 dy along the given paths, we need to parameterize each path and compute the corresponding integrals.

(a) Path along the arc of the parabola y = x^2:

We can parameterize this path as γ(t) = (t, t^2) for t in the interval [0, 2].

The line integral becomes:

∫ γ y^2 dz + x^2 dy = ∫[0,2] t^4 dz + t^2 x^2 dy

To express dz and dy in terms of dt, we differentiate the parameterization:

dz = dt

dy = 2t dt

Substituting these expressions, the line integral becomes:

∫[0,2] t^4 dt + t^2 x^2 (2t dt)

= ∫[0,2] t^4 + 2t^3 x^2 dt

= ∫[0,2] t^4 + 2t^5 dt

Integrating term by term, we have:

= [t^5/5 + t^6/3] evaluated from 0 to 2

= [(2^5)/5 + (2^6)/3] - [0^5/5 + 0^6/3]

= [32/5 + 64/3]

= 192/15

= 12.8

Therefore, the line integral along the arc of the parabola y = x^2 is 12.8.

(b) Path along the horizontal interval followed by the vertical interval:

We can divide this path into two segments: γ1 from (0, 0) to (2, 0) and γ2 from (2, 0) to (2, 4).

For γ1, we have a horizontal line segment, and for γ2, we have a vertical line segment.

For γ1:

Parameterization: γ1(t) = (t, 0) for t in the interval [0, 2]

dz = 0 (since it is a horizontal segment)

dy = 0 (since y = 0)

The line integral along γ1 becomes:

∫ γ1 y^2 dz + x^2 dy = ∫[0,2] 0 dz + t^2 x^2 dy = 0

For γ2:

Parameterization: γ2(t) = (2, t) for t in the interval [0, 4]

dz = dt

dy = dt

The line integral along γ2 becomes:

∫ γ2 y^2 dz + x^2 dy = ∫[0,4] t^2 dz + 4^2 dy

= ∫[0,4] t^2 dt + 16 dt

= [t^3/3 + 16t] evaluated from 0 to 4

= [4^3/3 + 16(4)] - [0^3/3 + 16(0)]

= [64/3 + 64]

= 256/3

≈ 85.33

Therefore, the line integral along the horizontal and vertical intervals is approximately 85.33.

(c) Path along the vertical interval followed by the horizontal interval:

We can divide this path into two segments: γ3 from (0, 0) to (0, 4) and γ4 from (0, 4) to (2, 4).

For γ3:

Parameterization: γ3(t) = (0, t) for t in the interval [0, 4]

Answers

The given vector field F = (3x + 7y, 7x + 5y) is conservative since its partial derivatives satisfy the condition. To find a function f(x, y) such that F = ∇f, we integrate the components of F and obtain f(x, y) = 3/2x² + 7xy + 5/2y² + C

To determine if the vector field F = (3x + 7y, 7x + 5y) is conservative, we need to check if its components satisfy the condition of being conservative.

The vector field F is conservative if and only if its components have continuous first-order partial derivatives and the partial derivative of the second component with respect to x is equal to the partial derivative of the first component with respect to y.

Let's check the partial derivatives:

∂F₁/∂y = 7

∂F₂/∂x = 7

Since ∂F₂/∂x = ∂F₁/∂y = 7, the vector field F satisfies the condition for being conservative.

To find a function f(x, y) such that F = ∇f, we integrate the components of F:

∫(3x + 7y) dx = 3/2x² + 7xy + C₁(y)

∫(7x + 5y) dy = 7xy + 5/2y² + C₂(x)

Combining these results, we have:

f(x, y) = 3/2x² + 7xy + 5/2y² + C

where C is an arbitrary constant.

To evaluate ∫F · dr along the curve C, we substitute the parametric equations of the curve into the vector field F and perform the dot product:

∫F · dr = ∫[(3x + 7y)dx + (7x + 5y)dy]

Substituting the parametric equations of the curve C:

x = t + 1

y = t³

We have:

∫F · dr = ∫[(3(t + 1) + 7(t³))(dt) + (7(t + 1) + 5(t³))(3t²)(dt)]

Simplifying and integrating, we can evaluate the integral to find the value of ∫F · dr along the curve C.

te the calculations. . d²y Find For which values dx2 of t is the curve concave upward? C(t) = (t - t?, t-t3) =

Answers

Since the second derivative d²y/dx² is negative at t = 1/2, the curve is concave downward at the point (1/4, 3/8).

To find the concavity of the curve defined by C(t) = (t - t^2, t - t^3), we need to calculate the second derivative of y with respect to x.

The parametric equations x = t - t^2 and y = t - t^3 can be expressed in terms of t. To do this, we solve x = t - t^2 for t:

t - t^2 = x

t^2 - t + x = 0

Using the quadratic formula, we can solve for t:

t = (1 ± √(1 - 4x))/2

Now, we differentiate both sides of x = t - t^2 with respect to t to find dx/dt:

1 = 1 - 2t

2t = 1

t = 1/2

We can substitute t = 1/2 into the equations for x and y to find the corresponding point:

x = (1/2) - (1/2)^2 = 1/4

y = (1/2) - (1/2)^3 = 3/8

So the point on the curve C(t) at t = 1/2 is (1/4, 3/8).

Now, let's find the second derivative of y with respect to x:

d²y/dx² = d/dx(dy/dx)

First, we find dy/dx by differentiating y with respect to t and then dividing by dx/dt:

dy/dt = 1 - 3t^2

dy/dx = (dy/dt)/(dx/dt) = (1 - 3t^2)/(2t)

Now, we differentiate dy/dx with respect to x:

d(dy/dx)/dx = d/dx((1 - 3t^2)/(2t))

= (d/dt((1 - 3t^2)/(2t)))/(dx/dt)

= ((-6t)/(2t) - (1 - 3t^2)(2))/(2t)

= (-3 - 1 + 6t^2)/(2t)

= (6t^2 - 4)/(2t)

= (3t^2 - 2)/t

We can substitute t = 1/2 into d²y/dx² to find the concavity at the point (1/4, 3/8):

d²y/dx² = (3(1/2)^2 - 2)/(1/2)

= (3/4 - 2)/(1/2)

= (-5/4)/(1/2)

To integrate the expression ∫(-∞ to x) (3x+1)³ dx, we can use the power rule of integration and apply the limits of integration to obtain the exact answer.

The given expression is ∫(-∞ to x) (3x+1)³ dx. We can use the power rule of integration to integrate the expression. Applying the power rule, we increase the power by 1 and divide by the new power. Thus, the integral becomes:

∫ (3x+1)³ dx = [(3x+1)⁴ / 4] + C

To evaluate the definite integral with the limits of integration from -∞ to x, we substitute the upper limit x into the antiderivative and subtract the result with the lower limit -∞:

= [(3x+1)⁴ / 4] - [(3(-∞)+1)⁴ / 4]

Since the lower limit is -∞, the term [(3(-∞)+1)⁴ / 4] approaches 0. Therefore, the exact answer to the integral is:

outside temperature over a day can be modelled as a sinusoidal function. suppose you know the high temperature for the day is 63 degrees and the low temperature of 47 degrees occurs at 4 am. assuming t is the number of hours since midnight, find an equation for the temperature, d, in terms of t. g

Answers

In terms of t (the number of hours since midnight), the temperature, d, can be expressed as follows:

d = 8 * sin((π / 12) * t - (π / 3)) + 55

Explanation:

To model the temperature as a sinusoidal function, we can use the form:

d = A * sin(B * t + C) + D

Where:

- A represents the amplitude, which is half the difference between the high and low temperatures.

- B represents the period of the sinusoidal function. Since we want a full day cycle, B would be 2π divided by 24 (the number of hours in a day).

- C represents the phase shift. Since the low temperature occurs at 4 am, which is 4 hours after midnight, C would be -B * 4.

- D represents the vertical shift. It is the average of the high and low temperatures, which is (high + low) / 2.

Given the information provided:

- High temperature = 63 degrees

- Low temperature = 47 degrees at 4 am

We can calculate the values of A, B, C, and D:

Amplitude (A):

A = (High - Low) / 2

A = (63 - 47) / 2

A = 8

Period (B):

B = 2π / 24

B = π / 12

Phase shift (C):

C = -B * 4

C = -π / 12 * 4

C = -π / 3

Vertical shift (D):

D = (High + Low) / 2

D = (63 + 47) / 2

D = 55

Now we can substitute these values into the equation:

d = 8 * sin((π / 12) * t - (π / 3)) + 55

Therefore, the equation for the temperature, d, in terms of t (the number of hours since midnight), is:

d = 8 * sin((π / 12) * t - (π / 3)) + 55

B. S = (1,2)
C. S = {0, 1,2).
D. S = [HH. HT, TT).

Answers

The sample space for this probability model is A. S = (HH, HT, TH, TT). Each outcome represents a different combination of heads and tails obtained from the two flips of the coin.

The sample space for flipping a fair coin twice and counting the number of heads consists of four outcomes: HH, HT, TH, and TT.

When flipping a fair coin twice, we consider the possible outcomes for each flip. For each flip, we can either get a head (H) or a tail (T). Since there are two flips, we have two slots to fill with either H or T.

To determine the sample space, we list all the possible combinations of H and T for the two flips. These combinations are HH, HT, TH, and TT.

Answers

The surface area of the part of the sphere x² + y² + z² = 64 above the cone [tex]z = √(22 + y²) is 64π - 16π√2.[/tex]

To find the surface area, we need to calculate the area of the entire sphere (4π(8²) = 256π) and subtract the area of the portion below the cone. The cone intersects the sphere at z = √(22 + y²), so we need to find the limits of integration for y, which are -√(22) ≤ y ≤ √(22). By integrating the formula 2πy√(1 + (dz/dy)²) over these limits, we can calculate the surface area of the portion below the cone.

at a particular temperature, the solubility of he in water is 0.080 m when the partial pressure is 1.7 atm. what partial pressure (in atm) of he would give a solubility of 0.230 m?

Answers

To determine the partial pressure of helium (He) that would result in a solubility of 0.230 m, we can use Henry's law, which states that the solubility of a gas in a liquid is directly proportional to its partial pressure.

According to the problem, at a particular temperature, the solubility of He in water is 0.080 m when the partial pressure is 1.7 atm. We can express this relationship using Henry's law as follows:

0.080 m = k(1.7) atm

where k is the proportionality constant.

To find the value of k, we divide both sides of the equation by 1.7 atm:

k = 0.080 m / 1.7 atm

k ≈ 0.0471 m/atm

Now, we can use this value of k to determine the partial pressure that would result in a solubility of 0.230 m:

0.230 m = 0.0471 m/atm * P

Solving for P, we divide both sides of the equation by 0.0471 m/atm:

P ≈ 0.230 m / 0.0471 m/atm

P ≈ 4.88 atm

Therefore, a partial pressure of approximately 4.88 atm of He would give a solubility of 0.230 m.

find a unit vector that is orthogonal to both → u = ⟨ 2 , − 2 , − 6 ⟩ and v = ⟨ 1 , − 9 , − 3 ⟩ .

Answers

A unit vector orthogonal to both →u = ⟨2, -2, -6⟩ and →v = ⟨1, -9, -3⟩ is ⟨-0.965, 0, -0.257⟩.

To find a unit vector that is orthogonal (perpendicular) to both vectors →u = ⟨2, -2, -6⟩ and →v = ⟨1, -9, -3⟩, use the cross product.

The cross product of two vectors →u and →v, denoted as →u × →v, yields a vector that is perpendicular to both →u and →v. The magnitude of this vector can be adjusted to become a unit vector by dividing it by its own magnitude.

→u × →v = ⟨u₂v₃ - u₃v₂, u₃v₁ - u₁v₃, u₁v₂ - u₂v₁⟩

Substituting the values,

→u × →v = ⟨(-2)(-3) - (-6)(-9), (-6)(1) - (2)(-3), (2)(-9) - (-2)(1)⟩

         = ⟨-6 - 54, -6 + 6, -18 + 2⟩

         = ⟨-60, 0, -16⟩

To obtain a unit vector, we need to normalize this vector by dividing it by its magnitude:

Magnitude of →u × →v = sqrt((-60)^2 + 0^2 + (-16)^2)

                    = sqrt(3600 + 0 + 256)

                    = sqrt(3856)

                   = 62.120

Dividing →u × →v by its magnitude, we get the unit vector:

Unit vector = ⟨-60/62.120, 0/62.120, -16/62.120⟩

           = ⟨-0.965, 0, -0.257⟩

Therefore, a unit vector orthogonal to both →u = ⟨2, -2, -6⟩ and →v = ⟨1, -9, -3⟩ is ⟨-0.965, 0, -0.257⟩.

Answers

Therefore, the solution to f^(-1)(x) = 0^(-1) is x = 1/(b - a), expressed in terms of a and b.

To find the solutions to f^(-1)(x) = 0^(-1), we need to solve for x when the inverse of the function f(x) equals -1. First, let's find the inverse of the function f(x). To find the inverse, we interchange x and y in the equation and solve for y:

y = 1/(ax + b)

Interchanging x and y:

x = 1/(ay + b)

Now, we can solve this equation for y:

1/(ay + b) = x

Multiplying both sides by (ay + b):

1 = x(ay + b)

Expanding:

1 = axy + bx

Rearranging the terms:

axy = 1 - bx

Solving for y:

y = (1 - bx)/(ax)

Now, we can set y equal to -1 and solve for x:

-1 = (1 - bx)/(ax)

Cross-multiplying:

-ax = 1 - bx

The value of the line integral ∫C (5, 9, 2) ⋅ ds, where C:r(t) = (t, t^2, 0) from 0 ≤ t ≤ 1, is 16.

To evaluate the line integral ∫C (5, 9, 2) ⋅ ds, where f(x, y, z) = 1 + v + u - z^2 and C:r(t) = (t, t^2, 0) from 0 ≤ t ≤ 1, we need to parameterize the curve C and calculate the dot product of the vector field and the differential vector ds. First, let's calculate the differential vector ds. Since C is a curve in three-dimensional space, ds is given by ds = (dx, dy, dz). Parameterizing the curve C:r(t) = (t, t^2, 0), we can calculate the differentials: dx = dt. dy = 2t dt. dz = 0 (since z = 0)

Now, we can compute the dot product of the vector field F = (5, 9, 2) and ds: (5, 9, 2) ⋅ (dx, dy, dz) = 5dx + 9dy + 2dz = 5dt + 18t dt + 0 = (5 + 18t) dt. To evaluate the line integral, we integrate the dot product along the curve C with respect to t: ∫C (5, 9, 2) ⋅ ds = ∫[0,1] (5 + 18t) dt. Integrating (5 + 18t) with respect to t, we get: ∫C (5, 9, 2) ⋅ ds = [5t + 9t^2 + 2t] evaluated from 0 to 1

Answers

The statement (d) "Not monotonic, bounded, and convergent" is true for the sequence defined as 12 + 22 + 32 + ... + (n + 2)2 = 2n2 + 11n + 15.

To determine if the sequence is monotonic, we need to analyze the difference between consecutive terms.

Taking the difference between consecutive terms, we get:

(2(n+1)^2 + 11(n+1) + 15) - (2n^2 + 11n + 15) = 4n + 13.

Since the difference between consecutive terms is 4n + 13, which is not a constant value, the sequence is not monotonic.

To check if the sequence is bounded, we examine the behavior of the terms as n approaches infinity. As n increases, the terms of the sequence grow without bound, as the leading term 2n^2 dominates.

Therefore, the sequence is not bounded.

Finally, since the sequence is not monotonic and not bounded, it cannot converge. Convergence requires the sequence to be both bounded and monotonic, which is not the case here.

Thus, the sequence defined as 12 + 22 + 32 + ... + (n + 2)2 = 2n^2 + 11n + 15 is not monotonic, bounded, or convergent.

Z follows a Standard Normal Distribution. 1. Find the Probability Density Function of Y = |2| 2. Find the Mean and Variance of Y

Answers

the variance of Y, Var(Y), is 2.

To find the probability density function (PDF) of the random variable Y = |2Z|, where Z follows a standard normal distribution, we need to determine the distribution of Y.

1. Probability Density Function (PDF) of Y:

First, let's express Y in terms of Z:

Y = |2Z|

To find the PDF of Y, we need to consider the transformation of random variables. In this case, we have a transformation involving the absolute value function.

When Z > 0, |2Z| = 2Z.

When Z < 0, |2Z| = -2Z.

Since Z follows a standard normal distribution, its PDF is given by:

f(z) = (1 / √(2π)) * e^(-z^2/2)

To find the PDF of Y, we need to determine the probability density function for both cases when Z > 0 and Z < 0.

When Z > 0:

P(Y = 2Z) = P(Z > 0) = 0.5 (since Z is a standard normal distribution)

When Z < 0:

P(Y = -2Z) = P(Z < 0) = 0.5 (since Z is a standard normal distribution)

Thus, the PDF of Y is given by:

f(y) = 0.5 * f(2z) + 0.5 * f(-2z)

    = 0.5 * (1 / √(2π)) * e^(-(2z)^2/2) + 0.5 * (1 / √(2π)) * e^(-(-2z)^2/2)

    = (1 / √(2π)) * e^(-2z^2/2)

Therefore, the probability density function of Y is f(y) = (1 / √(2π)) * e^(-2z^2/2), where z = y / 2.

2. Mean and Variance of Y:

To find the mean and variance of Y, we can use the properties of expected value and variance.

Mean:

E(Y) = E(|2Z|) = ∫ y * f(y) dy

To evaluate the integral, we substitute z = y / 2:

E(Y) = ∫ (2z) * (1 / √(2π)) * e^(-2z^2/2) * 2 dz

     = 2 * ∫ z * (1 / √(2π)) * e^(-2z^2/2) dz

This integral evaluates to 0 since we are integrating an odd function (z) over a symmetric range.

Therefore, the mean of Y, E(Y), is 0.

Variance:

Var(Y) = E(Y^2) - (E(Y))^2

To calculate E(Y^2), we have:

E(Y^2) = E(|2Z|^2) = ∫ y^2 * f(y) dy

Using the same substitution z = y / 2:

E(Y^2) = ∫ (2z)^2 * (1 / √(2π)) * e^(-2z^2/2) * 2 dz

       = 4 * ∫ z^2 * (1 / √(2π)) * e^(-2z^2/2) dz

E(Y^2) evaluates to 2 since we are integrating an even function (z^2) over a symmetric range.

Plugging in the values into the variance formula:

Var(Y) = E(Y^2) - (E(Y))^2

      = 2 - (0)^2

      = 2

Therefore, the variance of Y, Var(Y), is 2.
