The correct answer is A.) f(x)=
x+1
This is because using slope intercept form (y=mx+b), we can solve.
m = slope
b= y-intercept
If you look at the graph, you can see the line crosses they y-axis at 1.
And if you follow the line using rise over run, you find that it is 1/3.
But because it is a negative line, it makes the slope negative.
Hope this helps!

Answer:
a) Mean = 6.5, sample standard deviation = 3.50
b) Standard error = 0.7826
c) Point estimate = 6.5
d) Confidence interval: (5.1469 ,7.8531)
Step-by-step explanation:
We are given the following data set for students to earn bachelor's degrees.
4, 4, 4, 4, 4, 4, 4.5, 4.5, 4.5, 4.5, 4.5, 4.5, 6, 6, 8, 9, 9, 13, 13, 15
a) Formula:
where are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 6.25 + 6.25 + 6.25 + 6.25 + 6.25 + 6.25 + 4 + 4 + 4 + 4 + 4 + 4 + 0.25 + 0.25 + 2.25 + 6.25 + 6.25 + 42.25 + 42.25 + 72.25 = 233.5
b) Standard Error
c) Point estimate for the mean time required for all college is given by the sample mean.
d) 90% Confidence interval:
Putting the values, we get,
e) No, the confidence interval does not contain the value of 4 years. Thus, confidence interval is not a good estimator as most of the value in the sample is of 4 years. Most of the sample does not lie in the given confidence interval.
Answer:
$4406.7 is the profit.
explanation:
compound interest formula:
using this formula:
profit: $28406.7 - $24,000 = $4406.7
