Answer:

g(x) = -4(1/2x)^2

Step-by-step explanation:

If you could format this a little better, it would be helpful but here is what looks to be the answer to your question.

from the parent square function, there is a vertical stretch by a factor of 4, a horizontal stretch by a factor of 1/2, and a reflection across the x axis

Answer:

The new volume will be 3 3/8 or maybe 27/8 of its original volume.

Step-by-step explanation:

Cone Volume = PI * radius^2 * height / 3

So if radius = 1 and height = 1 then volume = 1.0472

When radius = 3 and height = .375 then volume = 3.5343

Volume increases by 3.5343 / 1.0472 = 3 and 3/8

A researcher is investigating a government claim that the unemployment rate is less than 5%. To test this claim, a random sample

DerKrebs [107]

Answer:

The test statistic for this hypothesis test for a proportion is z=1.90.

Step-by-step explanation:

This is a hypothesis test for a proportion.

The claim is that the unemployment rate is less than 5%.

Then, the null and alternative hypothesis are:

$H_0: \pi=0.05\\\\H_a:\pi$

The sample has a size n=1500.

The sample proportion is p=0.061.

$p=X/n=92/1500=0.061$

The standard error of the proportion is:

$\sigma_p=\sqrt{\dfrac{\pi(1-\pi)}{n}}=\sqrt{\dfrac{0.05*0.95}{1500}}\\\\\\ \sigma_p=\sqrt{0.000032}=0.0056$

Then, we can calculate the z-statistic as:

$z=\dfrac{p-\pi-0.5/n}{\sigma_p}=\dfrac{0.061-0.05-0.5/1500}{0.0056}=\dfrac{0.0107}{0.0056}=1.90$

Evaluate the expression 15 - n when n = 9

Margarita [4]

To do this, you simply need to substitute in 9 for n in the expression.

15 - n
= 15 - (9)
= 6

Hope this helps! :)
