A rectangle has a perimeter of 64 inches and a length of 22 inches. Which equation can you solve to find the width?

It's B because if one length is 22 then both lengths combined is 44 + the width. Since there are 2 of those, each are represented with w so basically you're adding 2w to the total length,44 which will end up to look like 44+ 2w

Perimeter is found by the formula 2l+2w, where l is the length and w is the width.

Since we have a length of 22 inches and a perimeter of 64 inches, the width can be found by solving the equation 2(22)+2w=64, or 2w+44=64.

"A cable TV company wants to estimate the percentage of cable boxes in use during an evening hour. An approximation is 20 percen

Answer:

The company should take a sample of 148 boxes.

Step-by-step explanation:

Hello!

The cable TV company whats to know what sample size to take to estimate the proportion/percentage of cable boxes in use during an evening hour.

They estimated a "pilot" proportion of p'=0.20

And using a 90% confidence level the CI should have a margin of error of 2% (0.02).

The CI for the population proportion is made using an approximation of the standard normal distribution, and its structure is "point estimation" ± "margin of error"

[p' ± $Z_{1-\alpha /2} * \sqrt{\frac{p'(1-p')}{n} }$ ]
