Use the remainder theorem and the factor theorem to determine whether (b + 4) is a factor of (b3 + 3b2 − b + 12).

a. the remainder is 0 and, therefore, (b + 4) isn't a factor of (b3 + 3b2 − b + 12).

b. the remainder is 0 and, therefore, (b + 4) is a factor of (b3 + 3b2 − b + 12).

c. the remainder isn't 0 and, therefore, (b + 4) isn't a factor of (b3 + 3b2 − b + 12).

d. the remainder isn't 0 and, therefore, (b + 4) is a factor of (b3 + 3b2 − b + 12).

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and standard deviation 129 chips. (a) what is the probability that a randomly selected bag contains between 1100 and 1500 chocolate chips, inclusive? (b) what is the probability that a randomly selected bag contains fewer than 1125 chocolate chips? (c) what proportion of bags contains more than 1225 chocolate chips? (d) what is the percentile rank of a bag that contains 1425 chocolate chips?
