Suppose that g(x) = f(x) + 2. Which statement best compares the graph of g(x) with the graph of f(x)?

Jlenok [28]

Answer:

A

Step-by-step explanation:

Since it mentions g(x) is f(x) + 2, it means the y-intercept of g(x) is 2 more than that of f(x).

This basically means that :

The graph of g(x) is shifted 2 units up.

Suppose you have a sample of size 42 with a mean of 30 and a population standard deviation of 7.4. What is the maximal margin of

9966 [12]

Answer:

The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.

Step-by-step explanation:

We have given,

The sample size n=42

The sample mean $\bar{x}=30$

The population standard deviation $\sigma=7.4$

Let $\alpha$ be the level of significance = 0.05

Using the z-distribution table,

The critical value at 5% level of significance and two tailed z-distribution is

$\pm z_{\frac{0.05}{2}}=\pm 1.96$

The value of margin of error is

$ME=z_{\alpha/2}(\frac{\sigma}{\sqrt{n}})$

$ME=1.96(\frac{7.4}{\sqrt{42}})$

$ME=1.96(1.1418)$

$ME=2.238$

The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.

Three times the difference of 5 and a number gives 30. Find the number.

Temka [501]

Answer:

Step-by-step explanation:

we need to write the equation. I came up with....

3(5 - x) = 30

so take the 3 away from the 30. I think your not supose to do the 3 because it out of the ( ). the opppisite of multiplication is division. so...

3 divided by 30 =10

rewrite

(5 - x) = 10

take the 5 away. the oppisite of subbtraction is addition.

5 + 10 = 15

check your; plug in x

3(5 - 15) = 30 This equation looks true!

Hope this helped! Please mark as brainliest! Thanks
