To find Will's mean score after getting a 50 on the next test, we need to calculate the new mean by including the score of 50.
First, let's determine the total sum of his scores from the first five tests. If his mean score is 62 on these five tests, then the sum of these scores can be found by multiplying the mean score by the total number of tests:
Sum of scores = Mean score * Number of tests
Sum of scores = 62 * 5
Sum of scores = 310
Next, we need to calculate the new sum of scores by including the score of 50 on the next test. Since the mean score is the sum of scores divided by the total number of tests, we can rearrange the formula to find the new sum of scores:
Sum of scores = Mean score * Number of tests
Sum of scores = New mean score * (Number of tests + 1)
Now, let's calculate the new sum of scores:
310 = New mean score * (5 + 1)
310 = New mean score * 6
To isolate the new mean score, we divide both sides of the equation by 6:
New mean score = 310 / 6
New mean score = 51.67 (rounded to two decimal places)
Therefore, if Will gets a score of 50 on the next test, his new mean score will be approximately 51.67.
