I am thinking you mean 93 to represent William's scores of 91, 92, and "q3"on three quizzes in Queston 8a
Answer:Average (x)= 92
b.William needs 97 as his third score to get as average of 90
Step-by-step explanation:
a.
The Average ( x) of the scores can solved using the Formulae
Average ( x)= Sum of scores / Number of Scores
Average ( x) = (Score 1 + Score 2 + Score 3) /3
Average (x)= (91, 92, and 93 )/3=276/3 = 92
b) Average ( x) of the scores = Sum of scores/ Number of Scores
Now let Score be represented as S such that
Average (x) = (S 1 + S 2 + S3 )/ 3
90 = 85+ 88+ S/ 3
90 x 3= 85+ 88 + S
270=173+ S
S= 270- 173
S=97
William needs 97 as his third score to get as average of 90

Answer
A) The range of the morning test scores is less than the range of the afternoon test scores.
Step by step explanation
Let's find range of the morning class
The lowest number = 75
The highest number = 99
The range of the morning class = 99 - 75
The range of the morning class = 24
Let's find the range of the afternoon class.
The lowest number = 67
THe highest number = 96
The range of the afternoon class = 96 - 67
The range of the afternoon class = 29
According to the range.
The answer A) The range of the morning test scores is less than the range of the of afternoon test scores.
