The Lifespans of a computer manufacturers hard drives are normally distributed with a mean of 3 years 6 months in a standard deviation of 9 months What is the probability of a randomly selected hard drive from the company last day 22 years three months and three years three months? Use The portion of the standard normal table below to help answer the question

answer is because 4×10=40

and 98×4= is 392

40,392

answer is 1

step-by-step explanation:

if i did my math right then the answer should but 108

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
