Answer:
1. rate = 30, base = 40, percentage = 12
2. rate = 6, base = 24, percentage = 25
3. rate = 16, base = 64, percentage = 25
4. rate = 4, base = 50, percentage = 20
5. rate = 75, base = 80, percentage = 60
Step-by-step explanation:
The data set represents the total number of tuba players in each of 11 different school bands. 0, 1, 3, 3, 4, 4, 4, 5, 6, 6, 8 W

Data set: <span>0, 1, 3, 3, 4, 4, 4, 5, 6, 6, 8
minimum : 0
1st quartile: 2
median: 4
3rd quartile: 6
maximum: 8
mean: 4
mean average deviation: 1.64
interquartile range: 4

A² + b² = c²
30² + 72² = c²
<u />900 + 5,184 = c²
6084 = c²
(Square root both sides)
c = 78 m
<u />
-5y+8=-3y+10
-5y+3y=10-8
-2y=2
-2y/-2=2/-2
y=-1
I grouped the alike variable to one side, and the number to the other side, added and subtracted it, divided both sides by -2, and got -1
