The mean salary offered to students who are graduating from coastal state university this year is 24245 dollars with a standard deviation of 3643 dollars a random sample of 80 coastal state students graduating this year has been selected what is the probability that the mean salary offer for those 80 students is $24,750 or less

Step-by-step explanation:

z(24750) = (27450-24260)/[3643/sqrt(85)] = 1.24007

P(z > 1.24007) = 10.747%

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

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.
