Answer:

Option D is correct.

The ordered pairs are found on the graph of the inverse function is,

{(12 , -2) (9 , -1), (6 , 0) , (3, 1) ,(0, 2)}

Step-by-step explanation:

Inverse of a function states that the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function.

Given the ordered set of the original function as:

Let f(x) = {(-2, 12) , (-1 , 9), (0 , 6) , (1, 3) ,(2, 0)}

Now, swap the values of x and y coordinates to get inverse of the original function.

i.e

Inverse of f(x) = {(12 , -2) (9 , -1), (6 , 0) , (3, 1) ,(0, 2)}

A random sample of 100 observations from a quantitative population produced a sample mean of 22.8 and a sample standard deviatio

natima [27]

Answer:

We conclude that the population mean is 24.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 24

Sample mean, $\bar{x}$ = 22.8

Sample size, n = 100

Alpha, α = 0.05

Sample standard deviation, s = 8.3

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 24\\H_A: \mu \neq 24$

We use Two-tailed z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{22.8 - 24}{\frac{8.3}{\sqrt{100}} } = -1.44$

We calculate the p-value with the help of standard z table.

P-value = 0.1498

Since the p-value is greater than the significance level, we accept the null hypothesis. The population mean is 24.

Now, $z_{critical} \text{ at 0.05 level of significance } = \pm 1.96$

Since, the z-statistic lies in the acceptance region which is from -1.96 to +1.96, we accept the null hypothesis and conclude that the population mean is 24.

Including 5% sales tax, an inn charges $252 per night. Find the inn’s nightly cost before the tax is added

stira [4]

Hi,

To find the cost before tax, we must find out how much the tax is. So we multiply 252 x .05 to get 12.6. So we know the tax was 12.6 dollars. Now all we have to do is subtract that from the total to get our answer. 252 - 12.6 = 239.4.

Have a great day!
