ASSUME ALL CONDITIONS HAVE BEEN MET FOR THE FOLLOWING PROBLEMS. Show all formula s, work, justifications and conclusions for each problem.
You want to estimate how much cash you are going to haul-in from graduation gifts, so you ask a random
sample of 8 people from your extended family who have recently graduated. They had a sample mean of
$1231 with a standard deviation of $71. Use this to construct a 90% confidence interval for the true mean
amount your family gives to graduate
a) On a separate sheet of paper, show all steps needed to solve for the confidence interval.
b) Enter on the computer write the inequality
c) On the computer state the conclusion

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

5050 i think

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
