Answer:
Caution. My best guess.
Step-by-step explanation:
See attached graph.
We don't have an actual equation for y=f(x). But I can write one that includes (8.15) and then make the changes as requested. The resulting new lines are shown for each:
A. y = f(x+5).
B. y = f(x) + 5.
Coordinates of a point for x=8 may be found on both lines.
For A: (8,25)
For B: (8,20)

The answer is below
Step-by-step explanation:
The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean, it is given by the equation:
Given that μ = 650, σ = 50. To find the probability that 5 students who have a mean of 490, we use:
From the normal distribution table, P(x < 490) = P(Z < -7.16) = 0.0001 = 0.01%
Since only a small percentage of people score about 490, hence the local newspaper editor should write a scathing editorial about favoritism
