Answer:
0.0062
Step-by-step explanation:
Find the standard error.
σ = 20 / √100
σ = 2
Find the z-score.
z = (x − μ) / σ
z = (70 − 65) / 2
z = 2.5
Find the probability.
P(Z > 2.5) = 1 − 0.9938
P(Z > 2.5) = 0.0062
Given is :
The area of the rectangular patio is = 130 square feet
Let the width of the patio be = x feet
As length is 3 feet more than the width, so the length is = x+3 feet
Now area of rectangle is = length * width
This gives either x-10=0 or x+13=0
x-10=0 ; x=10
x+13=0 ; x=-13 (neglect this negative value)
So, the width of the patio is = 10 feet
Length = 10+3 = 13 feet

Hope this helps (:
It can depend but if u are in a diet u can lose weight without exercising
For this case we have the following equation:
y = 3t + 6
Where we have the following variables:
t: time in minutes
y: distance traveled
We have then that the slope of the line is equal to 3.
The slope of the line represents the speed in feet per minute of the ant.
The speed of the ant is 3 feet per minute.
Answer:
C. The ant is crawling at 3 feet per minute
