Answer:
Step-by-step explanation:
z(lower) = (15-15)/4 = 0
z(upper) = (19-15)/4= 1
z at 0 = .5
z at 1 = 0.841344746
(look these up in a Z table)
probability "between" = 0.841344746 - .5 = 0.3841344746
23x-13=2(x+2)
First you would distribute the 2 into the parenthesis
It will look like this after: 23x-13=2x+4
Then you would subtract 2x on both sides because u have to get the x's on one side
It will look like this after:21x-13=4
Then you would add 13 to both sides
It will look like this after: 21x=17
Then you would divide 21 on both sides
Your final product is 21/17

Answer: Company B
Step-by-step explanation:
First we must calculate the area of the carpet. Variable A represents area.
So the area of the carpet is 168 square feet.
To find what company A will charge we will multiply the 168 by 2.75 they charge per square foot.
Company A charges, $462, while Company B will charge $450 for the one room.
This means Company B has the better price.
It should be a positive 5 not a negative so the error was made at the end because u divide
