Answer:

n = 484

Step-by-step explanation:

If Confidence Interval  CI = 95 %   then α = 5%  and α/2 = 2,5 %

α/2 = 0,0125

MOE for normal distribution is:

MOE = z * σ/√n

For α/2 = 0,0125    ⇒ z(score) = -2,2

MOE = |-2,2| * 4/√n

0,4*√n = 8,8

√n = 8,8 / 0,4

√n = 22

n = 484

A water tank was 1/8 full of water
vekshin1

Answer:

16,800 Liters

Step-by-step explanation:

Convert 3/4 into eighths, because it was already 1/8 full before the 10,500 liters were added:

3/4= 6/8

Subtract 1/8 from that (because it was already 1/8 full):

6/8-1/8= 5/8

Divide 10,500 by the 5 (because you want how many liters each part is):

10,500/5= 2,100

You know can say that every eighth is 2,100 Liters of water.

Multiply that by the 8 total parts it can hold:

2,100x8= 16,800 Liters
