We have the following arithmetic series:
4, 13, 22, 31, 40
The common difference is given by:
13-4 = 9
22-13 = 9
31-22 = 9
40-31 = 9
Since it is an arithmetic series, the difference is constant.
Answer:
The common difference is:
9

Answer:
Variance of the given data = 31.143
Explanation:
Variance, , where n is the number of observations, μ is the mean and is the observations made.
Number of observations, n = 7
Mean, μ =
So variance of the given data = 31.143
Answer:
1 hour and 30 minutes.
Step-by-step explanation:
While carrying her fancy 360-degree camera, a crew artist Sarah Jane can walk at a rate of 2 miles per hour.
We are asked to determine the time required by Sarah to walk to a place that is 3 miles away from her.
Since Sarah can walk at a rate of 2 miles per hour.
Hence, she walks 3 miles in hours i.e. 1 hour and 30 minutes. (Answer)
{Here we have used the unitary method assuming that Sarah walks at a constant rate}
