Step-by-step explanation:

The mean of the given data is 7.57 and the median of the given data is 8

Given that a data set i.e. Xi= 1,3,5,8,12,15,9. asked to find the mean and median of the given data.

Mean:

The mean is the average of the supplied numbers and is computed by dividing the total number of numbers by the sum of the given numbers.

Mean= [tex]\frac{sum of observation}{number of observation}[/tex]

Mean=[tex]\frac{1+3+5+8+12+15+9}{7}[/tex]

Mean=[tex]\frac{53}{7}[/tex]

Mean=7.57

The mean of the given data is 7.57

Median:

The median is a statistical metric that identifies the midway value of an ascending-ordered dataset (i.e., from smallest to largest value). The metric separates the dataset's lower and upper halves.

Arranging in ascending-order⇒1,3,5,8,9,12,15.

Then median=8

Therefore,The mean of the given data is 7.57 and the median of the given data is 8

=================================================

Let's use the distance formula

[tex](x_1,y_1) = (3,0) \text{ and } (x_2, y_2) = (-1,-2)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-(-1))^2 + (0-(-2))^2}\\\\d = \sqrt{(3+1)^2 + (0+2)^2}\\\\d = \sqrt{(4)^2 + (2)^2}\\\\d = \sqrt{16 + 4}\\\\d = \sqrt{20}\\\\d = \sqrt{4*5}\\\\d = \sqrt{4}*\sqrt{5}\\\\d = 2\sqrt{5}\\\\d \approx 4.4721\\\\[/tex]

The exact distance is [tex]2\sqrt{5}[/tex] units.

The logarithmic expansion of logs(20x + 5y) by using the properties of logarithmic is log(5)+log(4x+y).

The basic logarithmic function is of the form f(x) = logₐx(r)n = logₐx, where a > 0. It is the inverse of the exponential function aⁿ = x. Log functions include natural logarithm (ln) or common logarithm (log). Logarithmic functions is very useful in various mathematical computations.

Given that, log(20x+5y) and we have to expand it by using the properties of logarithms. So, let's proceed to solve the question.

log(20x+5y)

we can write 20 in terms of powers like 20 = (2²)x5

log((2².5)x+5y)

log(5(2².5x/5+5y/5))

log(5(2²x+y))

log(5(4x+y))

∵ log(ab) = log(a)+log(b)

⇒log(5(4x+y)) = log(5)+log(4x+y)

Hence, on expanding log(20x+5y) by using the properties of logarithms we get log(5)+log(4x+y) as our required answer.

The probability that a random bird chosen from among these is NOT a duck is 0.67

Given the total number of birds = 262

No of geese = 65

No of ducks = 84

No of robins = 113

We need to find the probability that a random bird chosen from among these is not a duck is

P ( not a duck ) = (total number of birds  - no of ducks) / total number of birds

                         =  262 - 84 / 262

                         =  178 / 262

                          = 0.67

Step-by-step explanation:

hope this works :)

The solution of expression 19×50 is found as 950.

This property states that multiplying the product of two or more addends by a number produces the same outcome as multiplying each addend separately by the number and afterwards adding the products together.

In other words, the distributive property requires a phrase of the form:

A (B + C) can be simplified as A (B + C) = AB + AC.

This same applies foe the subtraction;

Thus, for the given numerical;

= 19×50

Using distributive property.

= (20 - 1)×50

Open the braces;

= 20×50 - 1×50

= 1000 - 50

= 950

Therefore, the solution of the numerical 19×50 is 950.

Option a is correct. f(x) has an inverse function because its graph passes the horizontal line test.

An inverse function is a function that serves to undo another function. That is, if f(x) produces y, then putting y into the inverse of f produces the output x.

From the graph we can see that the horizontal lines intersect less than 2 points, this shows that the f(x) has an inverse.

From the graph, it gets to know.

Using proportions, it is found that:

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

Before beginning the problem, we have that the symbol # represents a pound, which has 16 ounces.

The remaining fillets weight 4 # 15 oz = 4 pounds + 15/16 of a pound. Hence, considering the cost of $2.74 per pound:

4 x 2.74 + 15/16 x 2.74 = $13.53.

The total value of the remaining fillets is of $13.53.

The price per pound is still the same, of $2.54.

The yield is of 4 pounds + 15/16 of a pound = 4.9375 pounds out of 7 + 6/16 = 7.375 pounds, hence the percentage is:

4.9375/7.375 x 100% = 66.95%.

The salmon’s yield percentage is of 66.95%.

Hence, for 6 + 14/16 = 6.875 pounds, the yield would be of:

0.6695 x 6.875 = 4.6 pounds.

You would expect to yield 4.6 pounds of boneless salmon fillet from the next salmon weighing 6 # 14 oz.

Answer:

  a) the largest angle is 90°, making it a right triangle

  b) the shortest side is 9.5 cm long

Step-by-step explanation:

You want the largest angle and the shortest side in a triangle whose angles are in the ratio 1 : 2 : 3.

Let x represent the smallest angle. Then the other two angles are 2x and 3x. Their sum is ...

  x +2x +3x = 180°

  x = 30° . . . . . divide by 6

  3x = 90° . . . . find the largest angle

The largest angle is 90°, a right angle. So, the triangle is a right-angled triangle.

A triangle with angles of 30°, 60°, and 90° is a "special" right triangle. Its sides are in the ratio 1 : √3 : 2. That is, the shortest side is 1/2 the length of the longest side.

  shortest side = 1/2(19 cm) = 9.5 cm

The length of the shortest side in the triangle is 9.5 cm.

__

Additional comment

In case you're not familiar with the side length ratios of the 30-60-90 special triangle, you can figure the side length from the Law of Sines. That tells you ...

  a/sin(A) = b/sin(B) = c/sin(C)

where A, B, C are the angles; and a, b, c are their opposite sides.

The shortest side is opposite the smallest angle, so we have ...

  a/sin(30°) = (19 cm)/sin(90°)

  a = sin(30°)×(19 cm) = 1/2(19 cm) = 9.5 cm

The length of the shortest side is 9.5 cm.

What is a quadratic equation?

In algebra, a quadratic equation is any equation that can be rearranged in standard form as

ax² + b*x + c = 0

The figures a, b, and c are the portions of the equation and may be distinguished by calling them, independently, the quadratic measure, the direct measure, and the constant or free term.

The values of x that satisfy the equation are called results of the equation, and the roots or bottoms of the expression on its left-hand side.

A quadratic equation has at most two solutions.

Given,

Initial height h(0) = 3 ft

Initial upward velocity v(0) = 36 ft/sec

Given ball height after 't' seconds is h(t) = 3 + 36t - 16r²

for h= 19 ft

19 = 3 + 36 t - 16 r²

16 r² - 36 t + 16 = 0

4 r² - 9 t + 4 = 0

Quadratic equation for ax² + b*x + c = 0 is x = -b ±√b² - 4ac / 2a

By using the above formula we get

t = 9 ± √9² - 4*4*4 / 2*4

t = 9 ± √81 - 64 / 8

t = 9 ± √17 / 8

t = 9 + √17 / 8              t = 9 - √17 / 8

t = 9 + 0.5                    t = 9 - 0.5

t = 9.5                           t = 8.5
