The mean absolute deviation of the data for the West Avenue Branch is
. The mean absolute deviation of the data for the Water Field Road Branch is
. Based on the mean absolute deviations for the two data sets, we can conclude that the spread of the data for the West Avenue Branch is
than the spread of the data for the Water Field Road Branch.

You can literally just look up the equations and do the math on a calculator

Step-by-step explanation:

To find the mean absolute deviation's for both data sets, you calculate the mean, find the difference between the mean and each data point, and find the mean of those differences.

Please see the attached work for both MADs.

Both answers are C, and the spread of the data for West branch is lower than the spread for Water branch.

Step-by-step explanation: SMART:D

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
