5 0

Step-by-step explanation:

4x > 36-4

4x > 32 (divide both sides of the inequality by 4 )

4x ÷ 4 > 32 ÷ 4

x > 8

G(x) = 3x − 3; Find g(−6)

atroni [7]

Answer:

The correct answer is -21.

Step-by-step explanation:

To solve this problem, we must plug in -6 for each x in the function.

This is modeled below:

g(x) = 3x - 3

g(-6) = 3(-6) - 3

Now, we must simplify by first multiplying and then adding the remaining terms together.

g(-6) = -18 - 3

g(-6) = -21

Therefore, the correct answer is -21.

Hope this helps!

If a survey of a movie shows that 50% of all people who like the movie, enjoyed the official movie soundtrack too. If a total of

Murljashka [212]

Answer:

For the first question the sample size is n= 3850

$ME= z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}$

$\hat p \pm ME$

And replacing we got:

$0.5- 0.016 = 0.484$

$0.5+ 0.016 = 0.516$

We are confident at 95% that the true proportion of all people who like the movie is between 0.484 and 0.516.

Step-by-step explanation:

We have the following info given:

$\hat p = 0.5$ represent the estimated proportion of all people who like the movie

$n = 3850$ represent the sample size selected

For the first question the sample size is n= 3850

For the second part they gives to us the margin of error:

$ME = 0.016$

We know that the confidence interval for a population proportion $p$ of interest is given by:

$\hat p \pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}$

And the margin of error is given by:

$ME= z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}$

So then the confidence interval can be found with this formula:

$\hat p \pm ME$

And replacing we got:

$0.5- 0.016 = 0.484$

$0.5+ 0.016 = 0.516$

We are confident at 95% that the true proportion of all people who like the movie is between 0.484 and 0.516.
