A normal distribution has a mean of 14 and a standard deviation of 2.5. what is the probability that a randomly-selected x-value from the distribution is in the interval of [11.5, 19]?
a. 0.32
b. 0.68
c. 0.815
d. 0.95

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

i think the answer would be c
