Emma's final grade in her math class is the average (mean) of her 5 chapter tests she took throughout the year. if she received a 92%, 85%, 78%, 97%, and 88% on the five tests, what is her final grade?

Step-by-step explanation:

The mean (or average) of a set of numbers can be found with the following formula:

For this problem, we have five numbers, so we add them together and divide by 5:

88%

Step-by-step explanation:

Emma took tests of her 5 chapters throughout the year.

She received  the score on the five tests

92%, 85%, 78%, 97% and 88%

We have to calculate the average (mean) of her final grade.

average =  

=  

=  

= 88%

Her final grade would be 88%.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

do you have the measurements?
