Professor Liu gave the same quiz to the students in her morning class and in her afternoon class. The average (arithmetic mean)

natka813 [3]

Answer:

Afternoon class has more students.

Step-by-step explanation:

Let m be the number of students in the morning class and n be the number of students in the afternoon class.

The average score for the students in the morning class was 80, then the sum of their scores is $80m.$

The average score for the students in the afternoon class was 86, then the sum of their scores is $86n.$

The sum of the scores of both classes is

$80m+86n$

and the average score is

$\dfrac{80m+86n}{m+n}$

The average (arithmetic mean) score for the two classes combined was 84, then

$\dfrac{80m+86n}{m+n}=84\\ \\ 80m+86n=84m+84n\\ \\86n-84n=84m-80m\\ \\2n=4m\\ \\n=2m$

This means n is greater, so afternoon class has more students.

aniked [119]

I=prt. Sub in what you know: 562.50=1500(r)(5). Multiply: 562.5=7500r. Divide to get the unknown by itself: .075=r or 10%=r. :)

zlopas [31]

Answer:

He spent around $ 52.17 in each month.

Step-by-step explanation:

Last year the power bill price = $ 626.14 ≈ $ 626

We know that in a year 12 months. so power bill of each month in last year is calculated as follows

$Power \ bill \ of \ each \ month = \frac{Total \ bill \ of \ the \ year}{12}$

$Power \ bill \ of \ each \ month = \frac{626}{12}$

$Power \ bill \ of \ each \ month =$ $ 52.17

Therefore he spent around $ 52.17 in each month.
