Answer:
-1 x - 2
f (x) = -----------
3
Step-by-step explanation:
Then we have y = 3x + 2.
Next, interchange x and y, obtaining x = 3y + 2
Next, solve this result for y: 3y = x - 2; then divide both sides by 3:
y = (x-2)/3
Last, replace "y" with the inverse function label:
-1 x - 2
f (x) = -----------

Z-scores (left tail) of a given variable X are calculated by
Z(x)=(x-mean)/standard deviation.
For Mary:
Zm(124)=(124-110)/8=14/8=1.75
For Carrie:
Zc(289)=(289-250)/20=39/20=1.95
therefore
Zc>Zm
Answer:
3/5
Step-by-step explanation:
-24m-16 = -56
-24m = -40
m= 24/40
m= 3/5
45/75 = 30/x
30*75 = 2250/45 = 50
EF = 50 in.
