Answer:
Length of enlarged picture is 12.5 inches
Step-by-step explanation:
To determine the length of the enlarged picture, we need to compare the width of the original to the enlarged
This will enable us know the scale factor in use
that would be;
8.75/3.5 = 2.5
so the scale is 1 to 2.5
To get the length of the enlarged picture, we simply multiply the original length by 2.5
That would be 5 * 2.5 = 12.5 inches
Let X be the random variable.
We have:


Compute the mean like this:

It is the expected return.
First compute the following:

Then

Finally the standard deviation:
X= 3(y-1) then divided by 5
