64 - (3y + 8y + y) / 40 = 37
Simplify 3y + 8y + y
64 - 12y / 40 = 37
Add 12y / 40 to both sides and subtract 37
27 = 12y / 40
Multiply both sides by 40
1080 = 12y
Divide both sides by 12
90 = y
Answer:
mean = 11.66666
median = 11
Step-by-step explanation:
To find the mean, add up all the numbers, then divide by how many numbers
mean = (15+9+13+18+9+6) / 6 = 70/6 = 11 .6666666
To find the median, put the numbers from smallest to largest. then take the middle number. Since there is an even number, take the two middle numbers and average them
6,9,9,13,15,18
The two middle numbers are 9 and 13
(9+13)/2 = 22/2 = 11
