Answer:

Sum of squares of differences = 11239.74

Step-by-step explanation:

We are given the following data set:

63, 89, 92, 73, 79, 72, 34, 36, 94, 21, 25, 93, 22, 90, 79

We have to calculate the sum of square of the data set.

Formula:

$\text{Sum of square of differences} = \sum (x_i -\bar{x})^2$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{962}{15} = 64.13$

Sum of squares of differences =

1.284444444 + 618.3511113 + 776.5511113 + 78.61777778 + 221.0177779 + 61.88444445 + 908.0177776 + 791.4844443 + 892.017778 + 1860.484444 + 1531.417778 + 833.2844446 + 1775.217777 + 669.0844446 + 221.0177779

= 11239.74

anyanavicka [17]

Answer:

It takes 0.145 hours

Step-by-step explanation:

Given:

Distance = 8 miles

Speed = 55 miles per hour

To Find:

Time taken = ?

Solution:

The time taken for an object to travel a particular distance with a average speed can be found by

$\text{Time Taken} = \frac{distance}{ speed}$

Now Substituting the given values , we get

$\text{Time Taken} = \frac{8}{55}$

$\text{Time Taken} = 0.145$

Time taken will be 0.145 hours
