The mean of the data set =
Step-by-step explanation:
Please check the dot plot which is attached below.
As we know that we can determine mean from the dot plot by adding the numbers and then divide the resulting sum by the number of addends.
From the dot plot it is clear that:
So adding all the dots with respect to their values on the plot number by the total number of dots.
Thus
Mean = (1+1+1+2+2+2+2+3+3+3+4+4+4+4+5+5+5+5+5+6+6+6) ÷ 22
Hence, the mean of the data set =
C because 6-3=3-1/4=2 3/4 so c
Answer= 4 hours.
The first pipe can fill one pool in nine hours. So in one hour, it can fill 1/9th of the pool. Same with the other pipe, it can fill 1/6th of the pool in other hour.
So 1/9 + 1/6 would represent the first hour of filling the pool. Since 1/9 + 1/6 = .277.. , 27% of the pool is filled. Repeat this until you get to 100% (full pool).
First hour, 1/6 + 1/9 = .27
Second hour, 2/6 + 2/9 = .5
Third hour, 3/6 + 3/9 = .83
Fourth hour, 4/6 + 4/9 = 1.11
So in 4 hours, the pool will be filled.
