Answer:
0.5358
Step-by-step explanation:
Given
mean = μ = 13.2 inches
and
SD = σ = 2.2 inches
We have to find z-score for the given value 13.4 first
z-score = (x-μ)/σ
= (13.4-13.2)/2.2
=0.2/2.2
=0.0909
We have to find the area to the left of given z-score
The area to the left is 0.5358
So, the probability of choosing an item with length less than 13.4 is 0.5358 ..
Fill in the slope and that point in y=mx+b
-14=6(-12) + b
-14= -72 + b
b= 58
Y=6x + 58
