How can a telephone survey of 1000 randomly selected US adults provide evidence that more than 1 in 4 US adults believe in ghosts?The survey results provide evidence that more than one in four US adults believe in ghosts. The telephone survey was conducted on a random sample of 1000 US adults. The survey found that 31 percent of US adults believed in ghosts.

To determine whether more than one in four US adults believe in ghosts, the null and alternative hypotheses will be tested.The null hypothesis in this scenario is that less than or equal to 25% of US adults believe in ghosts. The alternative hypothesis is that more than 25% of US adults believe in ghosts.Therefore, the level of significance (α) will be determined.

The α level is typically set to 0.05. This means that the likelihood of making a type I error is 5%. Then, the z-score will be calculated as follows:z = (0.31 - 0.25) / sqrt[(0.25 x 0.75) / 1000]z = 2.83The obtained z-score will be compared to the critical z-value using a z-distribution table. The critical z-value is 1.96. Since the obtained z-score is greater than the critical z-value, the null hypothesis will be rejected. Therefore, there is evidence to suggest that more than one in four US adults believe in ghosts.

To find the zeros of y = tan(2x), we need to solve the equation sin(2x) = 0 to determine the x-values where sin(2x) is zero. These x-values will correspond to the zeros of the function tan(2x).

To find the zeros of the function y = tan(2x), we can utilize the fact that tan(x) is equal to sin(x)/cos(x).

Given y = tan(2x), we can rewrite it as:

y = sin(2x) / cos(2x)

Now, let's consider the numerator of this expression, which is sin(2x). If we set sin(2x) equal to zero, we can determine the values of x that make the numerator zero:

sin(2x) = 0

By solving this equation, we can find the zeros of sin(2x). The solutions will be the values of x for which sin(2x) equals zero.

Similarly, we can look at the denominator of the expression y = sin(2x) / cos(2x), which is cos(2x). If cos(2x) equals zero, the denominator will be zero, which leads to undefined values for y. These points will be vertical asymptotes of the function tan(2x).

To find the zeros of y = tan(2x), we need to solve the equation sin(2x) = 0 to determine the x-values where sin(2x) is zero. These x-values will correspond to the zeros of the function tan(2x).

Step-by-step explanation:

Calvin's age is now 23 years old.

9 years ago, Dallas was 3 times Calvin's age, which was 11.

Therefore, 9 years ago, Dallas was 33. 32 years ago, when Calvin was 0, Dallas was 32.

Since then, Dallas has aged 1 year for every year Calvin has aged, so Calvin is now 23 and Dallas is 55.

This problem can also be solved using algebra. Let x be Calvin's age now, and y be Dallas' age 9 years ago. We can then set up the following equation:

x + 32 = 3(y - 9)

We can simplify this to x + 32 = 3y - 27 and solve for x:

x = 3y - 27 - 32

Plugging in the given information that y = 33, we get:

x = 3(33) - 27 - 32 = 23

Therefore, Calvin is currently 23 years old.

In order to determine the break even number of cakes, the equation that Ava can use is 150+4.5c=12c

The number of cakes that Ava must sell before she has made as much money as she has spent is 20

What is breakeven quantity?

The breakeven quantity is the number of cakes that Ava needs to make in order to cover all costs incurred in producing cakes, in essence, it is the number cakes that makes total revenue to be the same as the total costs, which can be modeled using the below breakeven unit formula:

total revenue=total costs

total revenue=selling price*breakeven units

selling price=12

breakeven units=c

total revenue=12c

total costs=fixed costs+(variable cost*breakeven units)

fixed costs=cost of equipment=150

variable cost per cake=4.5

total costs=150+4.5c

12c=150+4.5c

150+4.5c=12c

150=12c-4.5c

150=7.5c

c=150/7.5

Step-by-step explanation:

Given parameters:

         Weight of the small box  = 125pounds

Unknown:

Weight of the larger box = ?

Solution:

The large box weighs \(3\frac{1}{3}\) times as the small box:

               So;

                =   125pounds x \(\frac{10}{3}\)

                = 416.7pounds

The weighted average cost of capital (WACC) for company C is 6.63%.

The weighted average cost of capital (WACC) is a financial metric that represents the average rate of return a company must earn on its investments to satisfy its shareholders and creditors. It takes into account the proportion of debt and equity in a company's capital structure and the respective costs associated with each.

To calculate WACC, we need to consider the cost of debt and the cost of equity. The cost of debt is the interest rate a company pays on its debt, adjusted for taxes. In this case, the pre-tax cost of debt is 2% and the tax rate is 24%. Therefore, the after-tax cost of debt is calculated as (1 - Tax Rate) multiplied by the pre-tax cost of debt, resulting in 1.52%.

The cost of equity represents the return required by equity investors to compensate for the risk associated with owning the company's stock. Here, the cost of equity for company C is 6%.

The debt represents 10% of the total capital, while the equity represents the remaining 90%. To calculate the weighted average cost of capital (WACC), we multiply the cost of debt by the proportion of debt in the capital structure and add it to the cost of equity multiplied by the proportion of equity.

WACC = (Proportion of Debt * Cost of Debt) + (Proportion of Equity * Cost of Equity)

In this case, the calculation is as follows:

WACC = (0.10 * 1.52%) + (0.90 * 6%) = 0.152% + 5.4% = 6.552%

Therefore, the weighted average cost of capital (WACC) for company C is approximately 6.63%.

Answer:

Either b or c

Step-by-step explanation:

The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.

To solve the inequality y + 7 ≤ -1, we need to isolate the variable y on one side of the inequality sign.

Starting with the given inequality:

y + 7 ≤ -1

We can begin by subtracting 7 from both sides of the inequality:

y + 7 - 7 ≤ -1 - 7

y ≤ -8

The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.

In the context of a number line, all values to the left of -8, including -8 itself, will make the inequality true. For example, -10, -9, -8, -8.5, and any other value less than -8 will satisfy the inequality. However, any value greater than -8 will not satisfy the inequality.

The value of the additional data point is 36

To find the value of the additional data point, we can use the concept of the sample mean.

Given the data set: 23, 28, 20, 33, 42, 12, 19, 50, 36, 25, 19.

The sample mean of this data set is 26.5.

To find the value of the additional data point, we can use the formula for the sample mean:

(sample mean) = (sum of all data points) / (number of data points)

In this case, we have 11 data points in the original data set. Let's denote the value of the additional data point as x.

Therefore, we can set up the equation:

26.5 = (23 + 28 + 20 + 33 + 42 + 12 + 19 + 50 + 36 + 25 + 19 + x) / 12

Multiplying both sides of the equation by 12 to eliminate the fraction, we have:

318 = 282 + x

Subtracting 282 from both sides of the equation, we find:

x = 318 - 282

x = 36

The lines L1 & L2 and the equations y = mx + n & y = px + q are illustrations of linear equations

This is a vertical line that passes through the x = 2

So, the equation of line L1 is x = 2

This is a horizontal line that passes through the y = 2

So, the equation of line L2 is y = 2

The line y = mx + n passes through points (6,3) and (0,0)

This means that n = 0 i.e. the y-intercept.

The value of m is calculated as follows:

\(m = \frac{y_2 -y_1}{x_2 -x_1}\)

This gives

\(m = \frac{0- 3}{0 - 6}\)

\(m = 0.5\)

So, the values of m and n in y = mx + n are 0.5 and 0, respectively.

The line y = px + q passes through points (6,3) and (0,12)

This means that q = 12 i.e. the y-intercept.

The value of p is calculated as follows:

\(p = \frac{y_2 -y_1}{x_2 -x_1}\)

This gives

\(p = \frac{12- 3}{0 - 6}\)

\(p = -1.5\)
