The weights for a group of 18-month-old girls are normally distributed with a mean of pounds and a standard deviation of pounds. Use the given table to find the percentage of 18-month-old girls who weigh between and pounds. z-score

% of 18-month-old girls weigh between and pounds.
(Round the final answer to the nearest hundredth as needed. Round the z-score to the nearest tenth as needed.)

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

i believe b is the answer
