4) In a time use study, 20 randomly selected managers spend a mean of 2.4 hours each day on paperwork. The standard deviation of the 20 times is 1.3 hours. Construct the 90% confidence interval for the mean paperwork time of all managers. .Which formula will you use

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

it would rotate about 180 degrees.

answer:

24pi or letter c
