Answer: Our required probability is 0.11.
Step-by-step explanation:
Since we have given that
Number of workers in first shift = 21
Number of workers in second shift = 15
Number of workers in third shift = 13
We need to find the probability of choosing exactly two second shift workers and two third shift workers.
So, it becomes,

Hence, our required probability is 0.11.
Answer:
i belive that the awnser is y=-1.25x+1000
Step-by-step explanation: you want to get y by itself so you would subtract x from both sides leaving you with
56y=-70x+56,000
then you would devide both sides by 56 leaving you with
y=-1.25x+1000
Answer:
101, 3, 0.025, 0.7416
Step-by-step explanation:
Given that a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101 and standard deviation equal to 12.
As per central limit theorem we have
a) Mean of sample mean = 
Std deviation of sample mean = 
Mean = 101
Std dev =3.00
b) 
c) the probability that the sample mean deviates from the population mean μ = 101 by no more than 4.
=
Total charge at park, T = 2×charge on adults + 4×charge on children .
T =$(2×16 + 4×10)
T = $72
Now, Melissa's father paid $100 .
Amount her father get back is :
A = $( 100 - 72 )
A = $28
Therefore, her father get $28 back.
Hence, this is the required solution.
