Draw out a number line. Plot the values -86, 0 and +45. To go from -86 to 0, you need to travel 86 meters. Then to go from 0 to 45, you need to travel another 45 meters.

In total, you have gone 86+45 = 131 meters (in the up direction)

The average of five distinct scores has the same value as the median of the five scores. The sum of the five scores is 420. What

givi [52]

Answer:

The sum of five scores that is not the median is, 336

Step-by-step explanation:

Average defined as the the sum of the observation to the total number of the observation.

Given: The sum of the five scores is 420

Then, by definition of average;

Average of five distinct score = $\frac{420}{5} = 84$

It is also, given that the average of five distinct scores has the same value as the median of the five scores.

⇒Median of five scores = 84

Since, scores are distinct, therefore

Sum of all scores that is not the median = Sum of five scores - median = 420-84 = 336

therefore, the sum of five scores that is not the median is, 336
