the exact average of a set of six test scores is 92. five of these scores are 90 98 96 94 and 85. what is the other test score?
add up the given scores, subtract them from the total (92*6).
To find the other test score, we can use the concept of average.
The average of a set of numbers is found by adding up all the numbers in the set and then dividing the sum by the total number of values.
In this case, we are given the average of six test scores (92). We also know five of these scores: 90, 98, 96, 94, and 85.
To find the other test score, we need to find the sum of all six test scores and then subtract the sum of the known scores. The result will give us the value of the missing test score.
Here's how to calculate it:
Step 1: Add the known scores:
90 + 98 + 96 + 94 + 85 = 463.
Step 2: Subtract the sum of the known scores from the average of all six scores:
Average = Sum of all scores / Total number of scores
92 = (463 + Missing Score) / 6.
Solving this equation will give us the missing test score:
92 * 6 = 463 + Missing Score.
552 = 463 + Missing Score.
Step 3: Subtract 463 from both sides:
552 - 463 = Missing Score.
89 = Missing Score.
Therefore, the missing test score is 89.
