These box plots show daily low temperatures for a sample of days in two
different towns.

Which statement is the most appropriate comparison of the centers?

A. The median for town A, 20", is less than the median for town B.
30°

B. The median temperature for both towns is 30°

C. The mean for town A. 20°, is less than the mean for town B, 30°

D. The median for town A, 30. is less than the median for town B.
40°

its adding 5.5 each time

step-by-step explanation:

they charge the same amount at 20 minutes.

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
