To answer this question correctly, first we must find out how much lou pays for health and disability insurance for a year total, then divide that number by 12, for each month of the year to find out how much he pays monthly. The calculation and answer would be the following: ((Health insurance cost * 30%) + (Disability cost * 10%)) / 12 = (1140+120)/12 = $105 monthly

"A cable TV company wants to estimate the percentage of cable boxes in use during an evening hour. An approximation is 20 percen
Marizza181 [45]

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} }]

Where

p' is the sample proportion/point estimator of the population proportion

Z_{1-\alpha /2} * \sqrt{\frac{p'(1-p')}{n} } is the margin of error (d) of the confidence interval.

Z_{1-\alpha /2} = Z_{1-0.05} = Z_{0.95}= 1.648

So

d= Z_{1-\alpha /2} * \sqrt{\frac{p'(1-p')}{n} }

d *Z_{1-\alpha /2}= \sqrt{\frac{p'(1-p')}{n} }

(d*Z_{1-\alpha /2})^2= \frac{p'(1-p')}{n}

n*(d*Z_{1-\alpha /2})^2= p'(1-p')

n= \frac{p'(1-p')}{(d*Z_{1-\alpha /2})^2}

n= \frac{0.2(1-0.2)}{(0.02*1.648)^2}

n= 147.28 ≅ 148 boxes.

I hope it helps!

It costs $68 for 16 square feet of flooring. How much does it cost for 12 square feet of flooring?
belka [17]
We know that it costs $68 for 16 square feet of flooring. To find out how much it costs for 12, we first have to find out how much it costs for 1 square foot.
To find that, we would do $68 divided by 16, which is 4.25.
That means 1 square foot costs $4.25.
Then, we would multiply $4.25 by 12 to find how much 12 square feet costs.
$4.25 times 12 is 51.

So, it would cost $51 to have 12 square feet of flooring.

Find the fifth term in the geometric sequence, given the first term and the common ratio. a1=5 and r=-3
Lunna [17]

Answer:

<h2>405</h2>

Step-by-step explanation:

The nth term of a geometric sequence is given by the formula

Tn=ar^n^-^1

Given data

first term  a1=5 and

common ratio r=-3

n= 5

T5= 5*3^5^-^1\\T5= 5*3^4\\T5=5*81\\T5=405

The 5th term is 405
