Your science teacher recently gave a quiz to 28 students present in class. the class average was an 82.5. five students that were absent made up the quiz after schoolamd their scores were a 78, 89,92,,99, & 63. find the new class average with the newscores

Total students in the class who got the quiz = 28

The average of the class average was = 82.5

Five students that were absent made up the quiz after school and their scores were a 78, 89,92,99, & 63.

The formula for an average= (sum of values) / (count of values)

As the average is given as 82.5 and there were 28 students, so sum of the 28 values will be =

Total students of the class = 28+5(absent) = 33

For 33 students the total score was = 2310 +(78+89+92+99+63)

= 2731

So, average for 33 students will be = or 82.76

So, the new class average is 82.76

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
