add how many parts (4+5=9)
45/9=5
4*5=20, 5*5=25

To find the mean of the data set you would add all the number of the data set (2,2,2,3,4,4,4,4,6,6,7,7,7,8 )-data set based on dot plot then add all number together which would give you 75 then you would divide by the amount of numbers (15) and 75/15=5 so your mean would be 5
A. Y= 3x-4
That should be the answer
$130 * x = $100
$130 ÷ $130 * x =$100÷$130
x = .77
100% - 77% = 23%
The discount is 23%
