Answer:
The rate of change will be the number of bags Fred fills for 1 customer.
Write a ratio.
21 : 3
x : 1
To solve for x, cross multiply.
3x : 21
Divide both sides by 3.
x = 7
Fred’s average rate of change is 7 bags.

Answer:
Step-by-step explanation:
From the given information, we already know two points the line intersects. It states that the line has a y-intercept of 3. The y-intercept is the point at which the line intersects the y-axis. Thus, the line also intersects (0,3). (Remember that all points on the y-axis have an x-value of 0.) Now we have enough information to write an equation.
1) Find the slope of the line with the slope formula, 
. Substitute the x and y values of (-5,2) and (0,3) into the formula and solve:
So, the slope of the line is 
.
2) Now we can write the equation in slope-intercept form, represented by the formula 
. Substitute values for 
and 
in the formula.
The represents the slope, so substitute for it. The represents the y-intercept, so substitute 
for it. This gives the following answer and equation in slope-intercept form:
For a 99% confidence interval for
μ based on a simple random sample.
Part (a):
Is it correct to say that
the probability that μ is in the specified interval is 99%?
Explain.
No. The probability that μ falls inside the interval is 0 or 1.
Rather we say that we are 99% confident that μ will fall inside the interval.
Part B:
Is it correct to say that in the long run, if you computed many,
many confidence intervals using the prescribed method, about 99% of
such intervals would contain μ?
Yes. 99% of intervals constructed using this method will capture
the population mean μ.
