Answer:
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
In this question, we will use slope intercept form that is y=mx +b, where m is the slope and b is the y intercept .
For the given question . x=1, y=-1 and slope , m = -5
We need to substitute these values in slope intercept form and solve for b, that is
-1=-5(1)+b
-1 = -5+b
Adding 5 to both sides
b =4
So we have slope, m =-5 and b=4
THerefore required equation is
y=-5x+4
