Assume a population of weights is normally distributed. The average weight for the population is 154lbs. The standard deviation for the population is 12 lbs.
What proportion of the population weighs more than 142 lbs and less than 160 lbs? (Please write
your answer in decimal to the nearest ten-thousandth.)

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
