Let X be normally distributed with mean u = 143 and standard deviation o= 34. [You may find it useful to reference the z table.) a. Find AX s 100). (Round "z" value to 2 decimal places and final answer to 4 decimal places.)
PIX S 100)
b. Find P195 SX S110). (Round "x" value to 2 decimal places and final answer to 4 decimal places.)
P(95 SXS 110)
c. Find x such that PX s x) = 0.370. (Round "x" value and final answer to 3 decimal places.)

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)

i may be incorrect but i believe that her first error was in step one when she multiplyed her equation by 1/4 when she should have divided it by 1/4
