Ateacher instituted a new reading program at school. after 10 weeks in the program it was found that the mean reading speed of a random sample of 19 second grade students was 93.9 wpm. what might you conclude based on this result? select the correct choice and ifll in the answer box in your choice below.

(round to four decimal places as needed)

a). a mean reading rate of 93.9 wpm is unusual since the probability of obtaining a result of 93.9 wpm or more is the new program is abundantly more effective than the old program.

b). a mean reading rate of 93.9 wpm is not unusual since the probability of obtaining a result of 93.9 wpm or more the new program is not abundantly more effective than the old program.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

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!

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)
