The **sum of squares** is the method for finding the variation within the groups , between the groups and for the total sample.

Given an incomplete sentence about sum of **squares**.

We are required to fill the blank with the terms specified in options.

The sum of squares is basically the **sum** of the square of variation, where variation is defined as the spread between each individual value and the mean. In order to determine the sum of squares, the distance between each **data** point and the line of best fit is squared and then summed up. The line which is known as **line of of best fit** will minimize this value.

The **sum of squares** is the method for finding the variation within the groups, between the groups and for the **total** sample.In this method the variations between values are find out irrespective of whether it is of a group or not.

Hence the **sum** of **squares** is the method for finding the **variation** within the groups , between the groups and for the total **sample**.

The number of **miles** that he will have traveled after **3.5 hours** of driving on the highway is** 227.5 miles.**

The **function **given to solve the question is:** f(x) = 65x**

where, x = number of **hours**

Therefore, when he travelled for 3.5 hours, the number of **miles** will be gotten by **multiplying** 65 by 3.5.

f(x) = 65x

= 65 × 3.5

**= 227.5 miles**.

Therefore, the number of** miles** that he will have travelled after** 3.5 hours** of **driving** on the highway is** 227.5 miles.**

**Answer:**

100 - 2 = 98

$45 = 98

divide both sides by 98 to find the amount of 1%

45/98 =1%

0.45918367 = 1%

now multiply by 100 to find original price

0.45918367 X 100 = 45.92

100% = 45.92
