Answer:
12 feet
Step-by-step explanation:
Since the side length is a length, it will be positive and not negative, so we solve this equation for s by taking the positive square root of both sides of the equation. We get that s = 12, so the side length of a square with an area of 144 square feet is 12 feet.While -12 is "a square root" of 144, the square root operation here denotes a function from nonnegative real numbers to nonnegative real numbers. A function can only produce a single result. So the expression √144 evaluates to the positive root 12.Because one square foot is 144 square inches, divide the total number of square inches by 144.

Using the Fundamental Counting Theorem, the number of potential outcomes is given by: 
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with 
ways to be done, each thing independent of the other, the number of ways they can be done is:
There are five decisions, each with four options, hence:
The number of options is:

Answer: 10 customers.
Step-by-step explanation:
The formula to find the required sample size :
(1)
, where p= prior population proportion.
n= sample size.
= Population standard deviation from previous studies.
Let p be prior population proportion of the customers who click on ads on their smartphones .
As per given , we have
p=0.62
E= 0.27
For 92% confidence , significance level : 
The critical value of z for 92% confidence interval from z-table would be
Put theses values in the formula (1), we will get
Therefore , the company should survey 10 customers .
First you know that at 6 it was 75 degrees. Now it’s noon and the temperature is 18 degrees warmer. So when you add 75 and 18 you get 93 degrees. When the storm rolls in at 4 it says that your temperature dropped 21 degrees. So you need to subtract 21 from 93 (93-21) which will get you at 72 degrees at 4pm
