Answer: (0.25,0.33)
Step-by-step explanation:
A 99% confidence interval for population proportion is given by:-
, where
= sample proportion,
= sample size.
Given: 
A 99% confidence interval estimate of the proportion of adults who use the Internet for shopping:


Thus, a 99% confidence interval estimate of the proportion of adults who use the Internet for shopping = (0.25,0.33)
Hamburger 1.80lbs sausage is 1.90lbs
1.80+ 1.80+ 1.90=$5.50
(x-1)^3 / 2 = 27
For equations like this, we want to isolate x in order to get the value of it.
First, let's multiply both sides by 2 to eliminate the fraction.
(x-1)^3 = 27(2)
Now, let's take the cube root of both sides
(x-1) = ∛(27 * 2)
Now, simplify the root
x - 1 = 3∛2
Add both sides by 1
x = 1 + 3∛2
That's your answer.
Have an awesome day! :)
Hello!
You need to separate this into two rectangles and add their areas together
first rectangle
3 * 6 = 18
rectangle 2
3 * 2 = 6
18 + 6 = 24
the answer is 24in squared
Your answer is $2
She spent $2 on each pencil 2 x 7 = 14 take away 14 from 24 you get 10
