Answer:
Altogether James walked miles.
Step-by-step explanation:
The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.
Given
Distance of first walk = of a mile
Distance of second walk = 5/7
In order to find how much he walked altogether, we have to find the sum of both fractions.
Hence,
Altogether James walked miles.
Answer:
Mean = 30.9
Range = 80
Interquartile Range = 36
Step-by-step explanation:
The mean of a set of numbers is the sum divided by the number of terms. In other words that means 2, 22, 4, 36, 82, 44, 65, 30, 8, 16 go over a fraction like this. There are 10 numbers here so this is our denominator.
For the range, all we do is subtract the minimum value from the maximum which is 82 - 2. That gives us 80.
For the IQ Range....
Arrange the terms in ascending order.
2, 4, 8, 16, 22, 30, 36, 44, 65, 82
Then we need to find the median which is the average of the two middle terms.
So for the lower half of data 2, 4, 8, 16, 22 we have the median of 8
And for the upper half 30, 36, 44, 65, 82 we have the median of 44.
To find the IQ Range it is the difference between the first quartile (8) and the third (44)
So 44 - 8 = 36
