find the probability that the proportion of the sampled teenagers who own a smartphone is between 0.35 and 0.45

Suppose 60% of American adults believe Martha Stewart is guilty of obstruction of justice and fraud related to insider trading.

We will take a random sample of 20 American adults and ask them the question. Then the sampling distribution of the sample proportion of people who answer yes to the question is a binomial distribution.

A binomial distribution is a statistical distribution that represents the likelihood of one of two outcomes in a sequence of independent trials. Binomial distributions can be used to model a variety of phenomena, including flipping coins, rolling dice, and performing multiple independent experiments.

The probability of getting k successes in n trials in a binomial distribution with probability of success p and probability of failure q is given by the following formula:P (k) = nCk * p^k * q^(n-k)Where nCk is the binomial coefficient, which represents the number of ways to select k items from a set of n items without regard to order.

The function rule for this question is d = 90t.

The rate of the cheetah is given as 90 feet per second. The distance travelled by the cheetah is a function of seconds travelled. Let the distance be denoted as d and the time be denoted as t. The function is therefore a linear function of the form y = mx + b.

The equation can be expressed as d = 90t + b. The constant b is the initial distance travelled at time zero since the rate is constant. Therefore, b is zero when the time is zero. The final equation is given as follows: d = 90t, where d is the distance travelled, t is the time and 90 is the rate or speed of the cheetah.

This gives us a present value for the company with debt of $35,564 and a present value for the competitor without debt of $36,944. The difference in present values is $1,380, rounded to the nearest dollar. Therefore, the company with debt gives the contract a higher present value of $1,380.

The company with debt will have the higher present value for this contract. This is because, despite having a higher yield, the competitor without debt is only earning 2.3% on their excess money, while the company with debt is earning 8%.

To calculate the difference in present values, we need to first calculate the present value of each company's contract. To do this, we will use the present value formula, which is:

[tex]PV = C / (1 + r)n[/tex]

Where C is the contract amount, r is the rate of return, and n is the number of years. For the company with debt, we can substitute $40,000 for C, 8% for r, and 1.75 for n. For the competitor without debt, we can substitute $40,000 for C, 2.3% for r, and 1.75 for n.

the property tax on the Weber family's home is $3,999. To find the property tax on the Weber family's home, we can use the formula:

Property tax = assessed value x tax rate

First, we need to convert the tax rate from a percentage to a decimal. We can do this by dividing the tax rate by 100:

2.15% ÷ 100 = 0.0215

Now we can plug in the values we know into the formula:

Property tax = $186,000 x 0.0215

Property tax = $3,999

So the property tax on the Weber family's home is $3,999.

Property taxes are a common way for local governments to generate revenue to fund public services like schools, roads, and emergency services. The tax rate is usually based on the assessed value of the property, which is determined by a local assessor's office. It's important for homeowners to be aware of the property tax rates in their area so they can budget for this expense. Some homeowners may be eligible for property tax exemptions or reductions, so it's also worth checking with the local assessor's office to see if there are any options available.

The two solutions to e² = 6x using Newton's method are x_left = 1.23151 and x_right = 2.157545.

To find the solutions of e² = 6x using Newton's Method, we will follow these steps:

Let f(x) = e² - 6x. Then we want to find the roots of f(x) = 0, which are the solutions to e² = 6x.

We need to choose a starting point x₀. A good choice is x₀ = 1, since it's a reasonable approximation to the solutions.

Apply Newton's Method to find the next approximation x₁:

x₁ = x₀ - f(x₀)/f'(x₀),

where;

Plugging in the values, we get:

x₁ = x₀ - (e² - 6x₀)/(-6) = x₀ + (e²/6 - x₀)

Use x₁ as the new starting point and repeat the process until we achieve the desired level of accuracy.

In this case, we want to find the solutions to six significant figures, so we will repeat the process until the difference between xₙ and xₙ₋₁ is less than 0.000005 (the sixth decimal place).

Using a calculator, we can apply Newton's Method iteratively to find the two solutions:

Iteration 1:

x₁ = x₀ - f(x₀) / f'(x₀)

x₁ = 1 - (e² - 6)/(-6) = 1.231509

Iteration 2:

x₂ = 1.231509 - (e² - 6)/(-6) = 1.463018

Iteration 3:

x₃ = 1.463018 - (e² - 6)/(-6) = 1.694527

Iteration 4:

x₄ = 1.694527 - (e² - 6)/(-6) = 1.926036

Iteration 5:

x₅ = 1.926036 - (e² - 6)/(-6) = 2.157545

Parasubstitution is a type of electrophilic aromatic substitution in which the attacking electrophile is substituted into the para position of the aromatic compound. The stability of the carbocation formed during this process is influenced by the substituents present on the aromatic ring.intermediate.

Reason of effecting on parasubstitution:

This is due to the fact that these substituents provide electron density to the aromatic ring, which stabilizes the carbocation by delocalizing the positive charge throughout the ring.Electron withdrawing substituents (such as -NO2, -CN, -COR, -COOH, -SO3H, etc.) have a negative impact on the stability of the carbocation intermediate. T

  This is due to the fact that these substituents withdraw electron density from the aromatic ring, making the carbocation intermediate less stable.The substituent effect on carbocation stability in parasubstitution can be represented by the Hammett equation, which relates the substituent effect to the electronic properties of the substituent.

The equation is given by

:log (kX/kH) = ρσ

where kX and kH are the rate constants for the reaction with and without the substituent, respectively

The missing angle measures 139 degrees.

what is triangle?

A triangle is a polygon that has three sides, three angles, and three vertices. It is a two-dimensional figure that is formed by connecting three non-collinear points. The three sides of a triangle can be of different lengths or the same length, and the angles can also vary in size. The sum of the three angles of a triangle always adds up to 180 degrees. Triangles can be classified based on their side lengths and angle measurements.

In a right triangle, the sum of the two acute angles is always equal to 90 degrees. Therefore, we can find the missing angle by subtracting the two given angles from 90 degrees.

Let's call the missing angle "x". Then we have:

x + 21 + 20 = 180 (the sum of angles in any triangle is 180 degrees)

x = 180 - 21 - 20

x = 139 degrees

Therefore, the missing angle measures 139 degrees.

The greatest possible integer value of the radius of the circle is 7 inches.

The area of a circle is given by the equation[tex]$A = \pi r^2$[/tex]. We know that the area is less than [tex]$60\pi$[/tex] square inches, so the equation can be written as [tex]$60\pi > \pi r^2$[/tex]. We can solve for the radius by dividing both sides by [tex]$\pi$[/tex], which gives us [tex]$60 > r^2$[/tex]. Taking the square root of both sides gives us [tex]$r < \sqrt{60}$[/tex], which is approximately 7.74 inches. Therefore, the greatest possible integer value of the radius of the circle is 7 inches.

To explain this further, we can start with the equation for the area of a circle, which is[tex]$A = \pi r^2$[/tex]. Since the area is less than [tex]$60\pi$[/tex]square inches, this equation can be rewritten as[tex]$60\pi > \pi r^2$[/tex].

Answer:

To find out how much more expensive it is, per pound, to buy chicken thighs at Store B than at Store A, we need to compare the cost per pound at each store.

At SuperGrocery B, we know that 3 pounds of chicken thighs cost $34.80, so the cost per pound is:

$34.80 / 3 pounds = $11.60 per pound

At SuperGrocery A, we can use the information in the table to find the cost per pound for each amount of chicken thighs:

For 1.5 pounds of chicken thighs:

$13.52 / 1.5 pounds = $9.01 per pound

For 3 pounds of chicken thighs:

$27.03 / 3 pounds = $9.01 per pound

For 3.5 pounds of chicken thighs:

$31.54 / 3.5 pounds = $9.01 per pound

For 4.5 pounds of chicken thighs:

$40.55 / 4.5 pounds = $9.01 per pound

So the cost per pound of chicken thighs at SuperGrocery A is $9.01 per pound, which is less expensive than the cost per pound at SuperGrocery B, which is $11.60 per pound.

To find the difference between the two prices, we can subtract the cost per pound at SuperGrocery A from the cost per pound at SuperGrocery B:

$11.60 per pound - $9.01 per pound = $2.59 per pound

Therefore, it is $2.59 more expensive, per pound, to buy chicken thighs at SuperGrocery B than at SuperGrocery A.

As per the given fraction, Kayla has 7/8 pound of flour left in total.

Let's start by looking at the amount of white flour Kayla has. She has 7/8 pounds of white flour, and she uses 3/8 pounds in the recipe. To figure out how much white flour she has left, we need to subtract the amount she used from the amount she had to start with:

7/8 - 3/8 = 4/8

So Kayla has 4/8 pounds of white flour left. But we can simplify this fraction by dividing both the numerator and the denominator by 4:

4/8 ÷ 4/4 = 1/2

So Kayla has 1/2 pound of white flour left.

Now let's look at the wheat flour. Kayla has 4/8 pounds of wheat flour, and she uses 1/8 pound in the recipe. To figure out how much wheat flour she has left, we need to subtract the amount she used from the amount she had to start with:

4/8 - 1/8 = 3/8

So Kayla has 3/8 pound of wheat flour left.

To find out how much flour Kayla has left in total, we need to add the amount of white flour she has left to the amount of wheat flour she has left:

There are 4 different weekly plans that meet the condition

If Tycho wants to go for a run on the same weekdays every week, there are 7 choices for the first day of the week, 6 choices for the second day of the week, and 5 choices for the third day of the week (since he can't run on two consecutive days).

However, we have to be careful not to overcount the number of plans that meet the conditions. For example, if Tycho chooses Monday and Tuesday as his running days, that's the same as choosing Tuesday and Monday.

To avoid overcounting, let's first count the total number of possible plans, regardless of whether they meet the conditions or not. We can choose any two days of the week for Tycho to run, which can be done in 7 choose 2 ways (or C(7,2) ways), since order doesn't matter.

C(7,2) = 7!/(2!(7-2)!) = 21

So there are 21 possible plans, regardless of whether they meet the conditions or not.

Now let's count the number of plans that meet the conditions. Since Tycho wants to run on two days a week and not on consecutive days, there are only two possible patterns: (1) run on Monday and Thursday, or (2) run on Tuesday and Friday.

Each pattern can be done in 2 ways: either run on Monday and Thursday, or run on Thursday and Monday. Similarly, either run on Tuesday and Friday, or run on Friday and Tuesday.

So there are 4 plans that meet the conditions: (Monday, Thursday), (Thursday, Monday), (Tuesday, Friday), and (Friday, Tuesday).
