Answer:
6 quarters, 3 dimes, and 12 nickles
Step-by-step explanation:
Let's say Q is the number of quarters, D is the number of dimes, and N is the number of nickles.
From the information in the problem, we can write three equations:
25Q + 10D + 5N = 240
N = 2Q
Q = 2D
Solve the system of equations using substitution.
25(2D) + 10D + 5(2Q) = 240
50D + 10D + 10Q = 240
60D + 10(2D) = 240
60D + 20D = 240
80D = 240
D = 3
Q = 6
N = 12
There are 6 quarters, 3 dimes, and 12 nickles.
Answer: 0.9544
Step-by-step explanation:
As per given have ,
Population mean :
Standard deviation :
Sample size : n= 100
We assume that the population is normally distributed.
Let be the sample mean.
Now , the probability that the sample mean will be within ±10 of the population mean will be :-
Hence, the required probability is 0.9544.
i believe the correct answer would be x12/8.
i would say 18 different outcomes
