As seen in attachment, the reflection across the x-axis is just you flip the graph over x-axis (horizontal line).

Distribute the 2 first.

f(n) = 2n - 2 + 3n

Combine like terms.

f(n) = 5n - 2

What is the fifth term of the geometric sequence? 5, 15 , 45, ...

Virty [35]

The geometry sequence has the equation $a(n)=5(3^{n-1})$ .

The 5 represents the first number of the sequence and the 3 represents the common ratio.

a(5) = $5(3^{5-1})=5(3^{4})=5(81)=405$

answer: 405

In preparation for an earnings report, a large retailer wants to estimate p= the proportion of annual sales

mr Goodwill [35]

Using the z-distribution, it is found that the 95% confidence interval for the proportion of sales that occured in December is (0.1648, 0.2948).

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which:

$\pi$ is the sample proportion.

z is the critical value.

n is the sample size.

In this problem, we have a 95% confidence level, hence $\alpha = 0.95$ , z is the value of Z that has a p-value of $\frac{1+0.95}{2} = 0.975$ , so the critical value is z = 1.96.
