Answer:
$525+$115 = $640
Step-by-step explanation:
To find the number or rows, divide the total number of students by the number in each row.
63 / 7 = 9 rows.
First, reorder the numbers for each person.
The median is basically the middle number. If there are 2 middle numbers, then take the average of the two of them.
Pedro: 4, 5, 6, 7, 8, 9
The 2 middle numbers are 6 and 7. The average of 6 and 7 is 6.5 .
Median = 6.5
Alex: 3, 5, 5, 5, 9, 9
The 2 middle numbers are 5 and 5; so basically, the average is 5.
Median = 5
Jaime: 3, 4, 6, 8, 8, 9
The 2 middle numbers are 6 and 8 and thus, the average is 7.
Median = 7
So the answer should be Jaime.
The exponent indicates how many times the base is used as a factor.
