Hi there!

»»————-　★　————-««

I believe your answer is:

$n = 13$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Solving for 'n'...}}\\\\9 = n - 4\\-------------\\\rightarrow n - 4 = 9\\\\\rightarrow n - 4 + 4 = 9 + 4\\\\\rightarrow \boxed{n=13}\\$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Ms. wilson draws a model of the factorization of a polynomial with integer factors. her model is partially complete. a 2-column

lana [24]

The equation represented by Ms. Wilson's model is n² + 13n + 40 = (n + 8)(n + 5)

<h3>How to determine the equation of the model?</h3>

The partially completed model is given as:

| n

| n²

5 | 5n | 40

By dividing the rows and columns, the complete model is:

| n | 8

n | n² | 8n

5 | 5n | 40

Add the cells, and multiply the leading row and columns

n² + 8n + 5n + 40 = (n + 8)(n + 5)

This gives

n² + 13n + 40 = (n + 8)(n + 5)

Hence, the equation represented by Ms. Wilson's model is n² + 13n + 40 = (n + 8)(n + 5)

In 2012, about 24% of high-school seniors reported binge drinking (defined as five or more drinks in a row in the past two weeks

Artist 52 [7]

Answer: (0.24 - 1.96*0.019, 0.24 + 1.96*0.019)

Step-by-step explanation:

We know that the confidence interval population proportion (p) is given by :-

$\hat{p}\pm z*\cdot SE$

, where $\hat{p}$ = sample proportion.

z* = Critical value (Two -tailed)

SE = standard error

Given : In 2012, about 24% of high-school seniors reported binge drinking (defined as five or more drinks in a row in the past two weeks), a substantial drop since the late 1990s.

$\hat{p}=0.24$

SE = 0.019

Significance level = $\alpha=1-0.95=0.05$

Two-tailed value corresponds for $\alpha=0.05$ :

z*=1.96 [Using z-table]

Now, the 95% confidence interval for the proportion of high-school seniors in the sample who would report binge drinking will be :-

$0.24\pm (1.96)\cdot (0.019)=(0.24-1.96\times 0.019,\ 0.24+1.96\times 0.019)$

Hence, the correct answer = (0.24 - 1.96*0.019, 0.24 + 1.96*0.019)
