The heights of women aged 20 to 29 are approximately normal with mean 64 inches and standard deviation 2.7 inches. men the same age have mean height 69.3 inches with standard deviation 2.8 inches. what are the z-scores for a woman 5'11" tall and a man 5'4" tall?

The z-score is the number of standard deviations of a value x from the mean:

... z = (x -μ)/σ

For the woman ...

... z = (71 -64)/2.7 ≈ 2.59 . . . woman's z-score

For the man ...

... z = (64-69.3)/2.8 ≈ -1.89 . . . man's z-score

109 is the nearest whole number/final answer! : )

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
