Answer:
width:6, length:18
Step-by-step explanation:
You can subsititue width with x.
The length would then be 2x+6.
The value of width and length combined is 24.
The equation would be (2x+6)+(x)=24
Simplify to 3x+6=24
Subtract 6 from both sides giving 3x=18
Simplify to x=6
There's the width. Now you can substitute to find the length.
(6x2)+6=18
I hope this is right.

Answer:
The 95% confidence interval for the fraction of all shoppers during the year whose visit was because of a coupon they'd received in the mail is (0.2016, 0.2694).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
A store randomly samples 603 shoppers over the course of a year and finds that 142 of them made their visit because of a coupon they'd received in the mail.
This means that
95% confidence level
So , z is the value of Z that has a p-value of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the fraction of all shoppers during the year whose visit was because of a coupon they'd received in the mail is (0.2016, 0.2694).

Answer: 24
<u>Step-by-step explanation:</u>
The median is the middle number of the set. If the set contains an even number of terms, then the median is the average of the two middle numbers.
{12, 14, 16, 18, x-1, x+3, 30, 32, 35, 41}
Cross out the end terms to find the median: {X, X, X, X, x-1, x+3, X, X, X, X}
The median is the average of the two middle numbers (x-1 and x+3).
The 6th term is x+3 ⇒ 21 + 3 = 24
