Answer:  New Mean = $40,920

                New Median = $38,500

<u>Step-by-step explanation:</u>

5 employee's salaries are as follows in order from least to greatest:

       $32,000 - unknown - $38,500 - unknown - unknown

The median (middle number) is: $38,500

The mean (average) of the 5 salaries is: $40,300

If $3,100 is added to the $32,000 salary, then the mean(average) is increased by \dfrac{\$3100}{5\ salaries}=\$620.

Old Mean + increase = New Mean

$40,300  +  $ 620    = $40,920

The median (middle number) does not change. It is still $38,500

The height of Mountain P is 1,086 feet.The height of Mountain Q is 4 times the height of Mountain P.The area model shown below r
earnstyle [38]

Answer:

A=4000, B=80, C=24

Step-by-step explanation:

You forgot to put the correct area model, I attached it to the answer.

We have the fact that Mountain Q is 4 times the height of Mountain P. That's the "4" we have in the left side of our model. It's like having a multiplication table, next to the "4" we have "A" and upper this we have "1000", the only thing we have to do is multiplify 4*1000=4000. The next letter we have is B and below it we have "320", we divided it by 4, 320/4=80. The last letter we have is C, and is below a "6", we only have to multiplify it by 4, 6*4=24.

At the end we only sum our

  • A + 320 + c = 4344 (4 times the height of Mountain P).
  • 1000 + B + 6 = 1086(the height of the Mountain P).

Jan won 51.9% of the votes in the race for school secretary. She received 415 votes. About how many students are in the school?
slava [35]
Mental way:
415 / 51.9 * 100 = 800 students in the school.

detailed way:
x is the amount of students in the school.
51.9% * x = 415
(divide both sides by 51.9% (or 0.519))
x = 800 students
