A random sample of receipts for individuals eating at the terrace restaurant showed the sample mean to be x=$10.39 with a sample standard deviation s=$2.15. (a) use Chebyshev, s theorem to find the smallest interval centered on the mean in which we can expect at least 88.9% of the data to fall.
(b) if our sample is normally distributed, what interval will contain exactly 95% of our data?

correct answer is c. just did it

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
