EXPERT HELP: EXPLAIN THE ANSWER

a.the average size of a seventh-grade class is larger and varies more than that of a kindergarten class

Step-by-step explanation:

ok so we know the mean and the m.a.d of both data sets, so now all we have to do is analyze the data

so the class ranges for kindergarten is 17-21

and the class ranges for 7th grade is 25-34

here's where i prove 'a' to be the correct answer;

21-17=4

34-25=9

the ranges for 7th grade is 5 more than that of a kindergarten class making 'a' the right answer

**i know i'm not an expert but an ace, i've just been trying to become a genius, sorry :(**

good luck :)

hopefully, this helps

have a nice day !!

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.

add 8+12 to get a simplified answer of 12r-20
