Claire is paid $90 for 5 hours at this rate how many hours does it take for her to earn $126

Answer:

Step-by-step explanation: The answer is to be calculated with help of taking out averages of the households' Tvs.

In order to calculate the expected value we multiply each value of the random variable by its probability and then add the results.

(1 TV times 350/1000) + (2 TV times 500/1000) + (3 TV times 120/1000) + (4 TV times 30/1000) = 1.83.

on average, each household has 1.83 TVs.

As per the data given, a television channel conducted a study on the number of TVs per household in their service area. Out of 1000 households surveyed, 350 have one TV, 500 have two TVs, 120 have three TVs and 30 have four TVs. We need to determine the number of TVs each household has on average.To calculate the average number of TVs, we need to calculate the total number of TVs and divide that by the number of households.

Totals TVs = (Number of households with 1 TV × 1) + (Number of households with 2 TVs × 2) + (Number of households with 3 TVs × 3) + (Number of households with 4 TVs × 4)Total TVs

= (350 × 1) + (500 × 2) + (120 × 3) + (30 × 4)Total TVs = 350 + 1000 + 360 + 120

Total TVs = 1830

Average number of TVs per household = Total TVs / Number of households

Average number of TVs per household = 1830 / 1000

Average number of TVs per household = 1.83

The calculation of the 99% confidence interval is 26.57 and 33.43.

We are given that;

Standard deviation = 20

Number of convicted criminals= 225

Now,

1. Calculate the standard error of the mean using the formula:

\($$SE = \frac{SD}{\sqrt{N}}$$\) where SE is the standard error,

SD is the standard deviation and N is the sample size. In this case, SD = 20 and N = 225,

\(so $$SE = \frac{20}{\sqrt{225}} = \frac{20}{15} = 1.33$$\)

2. Calculate the 95% confidence interval using the formula:

\($$\bar{x} \pm z_{\alpha/2} \times SE$$ where $\bar{x}$ is the sample mean, $z_{\alpha/2}$\) is the critical value for a given confidence level and SE is the standard error.

In this case,

\($\bar{x} = 30$, $z_{\alpha/2} = 1.96$ for 95% confidence level and SE = 1.33, so $$30 \pm 1.96 \times 1.33 = 30 \pm 2.61 = (27.39, 32.61)$$\)

This means that we are 95% confident that the true population mean of years worked by white collar criminals is between 27.39 and 32.61.

3. Calculate the 99% confidence interval using the same formula but with a different critical value:

\($$\bar{x} \pm z_{\alpha/2} \times SE$$ In this case, $z_{\alpha/2} = 2.58$\)

for 99% confidence level and everything else remains the same,

\(so $$30 \pm 2.58 \times 1.33 = 30 \pm 3.43 = (26.57, 33.43)$$\)

Therefore, by percentage the answer will be 26.57 and 33.43.

Answer:

The method of substitution involves three steps:

Solve one equation for one of the variables.

Substitute (plug-in) this expression into the other equation and solve.

Resubstitute the value into the original equation to find the corresponding variable.

Step-by-step explanation:

To find the area of the region interior to r = 9 + 7sin(θ) below the polar axis, we can integrate the function from the lower bound of θ to the upper bound of θ and take the absolute value of the integral.

To find the area of the region formed by two petals of r = 8sin(3θ), we can integrate the function over the appropriate range of θ and take the absolute value of the integral. To find dy/dx for the given parametric equations x = t^(1/3) and y = 3 - t, we differentiate y with respect to t and x with respect to t and then divide dy/dt by dx/dt.

To find the area of the region interior to r = 9 + 7sin(θ) below the polar axis, we need to evaluate the integral ∫[lower bound to upper bound] |1/2 * r^2 * dθ|. In this case, the lower bound and upper bound of θ will depend on the range of values where the function is below the polar axis. By integrating the expression, we can find the area of the region. To find the area of the region formed by two petals of r = 8sin(3θ), we need to evaluate the integral ∫[lower bound to upper bound] |1/2 * r^2 * dθ|.

The lower bound and upper bound of θ will depend on the range of values where the function forms the desired shape. By integrating the expression, we can calculate the area of the region. To find dy/dx for the parametric equations x = t^(1/3) and y = 3 - t, we differentiate both equations with respect to t. Taking the derivative of y with respect to t gives dy/dt = -1, and differentiating x with respect to t gives dx/dt = (1/3) * t^(-2/3). Finally, we can find dy/dx by dividing dy/dt by dx/dt, resulting in dy/dx = -3 * t^(2/3).

Step-by-step explanation:

The formula for the nth partial sum of the series is equal to Sn = ln √(n+1), and the series diverges.

Get a formula for the nth partial sum of the series, by writing out the first few terms,

S₁ = (ln √2 - ln √1)

   = ln √2

S₂ = (ln √3 - ln √2) + (ln √2 - ln √1)

   = ln √3 - ln √1

S₃= (ln √4 - ln √3) + (ln √3 - ln √2) + (ln √2 - ln √1)

   = ln √4 - ln √1

Pattern here expressed the nth partial sum is equal to

ln √(n+1) - ln √1.

Simplify this to,

ln (√(n+1)/√1)

= ln √(n+1).

nth partial sum is equal to,

Sn = ln √(n+1)

Series converges or diverges,

Take the limit of the nth partial sum as n approaches infinity we have,

\(\lim_{n \to \infty}\) ln √(n+1)

= ln ∞

= ∞

Here, the limit of the nth partial sum diverges to infinity, the series itself diverges.

⇒the series does not have a sum.

Therefore, the nth partial sum of the series is Sn = ln √(n+1), and the series diverges.

The graph of the linear equation:

-x + y = 1

Can be seen in the image at the end.

A general linear equation in standard form is written as:

a*x + b*y = c

In this case, we have the linear equation:

-x + y = 1

To graph it, we need to find two points on the line, to find them we need to evaluate the linear equation.

For example, if x = 0 we will get:

-0 + y = 1

y = 1

Then we have the point (0, 1)

If x = 1, we will get:

-1 + y = 1

y = 1 + 1

y =2

So we have the point (1, 2)

Then we can graph these two points and then draw a line that connects the two points, then the graph of the linear equation is the one you can see below.

In a two-tail hypothesis test, if the calculated test statistic (z-statistic) is -1.58 and the level of significance is used, the decision will depend on comparing the z-statistic to the critical values of the standard normal distribution corresponding to the desired level of significance.

Explanation: In a two-tail hypothesis test, the null hypothesis assumes that there is no significant difference between the sample and population parameters. The alternative hypothesis, on the other hand, suggests a significant difference. The level of significance, denoted as α, determines the critical values that divide the rejection and non-rejection regions.

If the calculated test statistic, in this case -1.58, falls within the rejection region, which is determined by the critical values, we reject the null hypothesis. If the test statistic falls outside the rejection region, we fail to reject the null hypothesis.

To make a decision, we compare the z-statistic to the critical values corresponding to the level of significance. If the z-statistic of -1.58 falls outside the critical values, it means it is not extreme enough to reject the null hypothesis, and we fail to reject it. However, if the z-statistic falls within the critical values, we reject the null hypothesis in favor of the alternative hypothesis.

Use and gratification theory is an approach to understanding why and how people actively seek certain media to satisfy certain needs. The theory states that media consumers are passive consumers of mass communication; Rather, they play an active role in media consumption.

After the introduction of use and gratification theories, scholars have generally viewed audiences as active participants who seek, evaluate, use, and consume media for various reasons, purposes, and in various ways.

Explain how people use the media for their own needs and are satisfied when their needs are met. In other words, the theory proves what people do to the media, not what the media does to people.

The length of the straw is 3.74 inches.

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

In rectangular box,

Length (l) = 2 inches

Width (w) = 1 inches

Height (h) = 3 inches

Here, The straw is said to fit into the box diagonally from the bottom.

So, the length (s) of the straw is calculated as:

⇒ s = √ l² + w² + h²

⇒ s = √ 2² + 1² + 3²

⇒ s = √ 4 + 1 + 9

⇒ s = √ 14

⇒ s = 3.74 inches
