The First Equation:
y-5=6/5(x-3)
y-5= (6/5)x -3.6
y= (6/5)x+1.4
The Second Equation:
y+1=6/5(x+2)
y+1=(6/5)x+2.4
y = (6/5)x +1.4
Answer:
10.56%
Step-by-step explanation:
We are given A compact disc is designed to last an average of 4 years with a standard deviation of 0.8 years.
We are supposed to find What is the probability that a CD will last less than 3 years
We will use z-score formula:
Substitute the values in the formula
Now refer the z score table
So, the value of -1.25 is 0.1056 =
Thus , the probability that a CD will last less than 3 years is 10.56%
