The shop would have repaired 10 because Jeff only repaired half so you would do 5 x 2 = 10 to double what Jeff did to show how many bikes the shop fixed.
It is 2/3 I believe
By calculating the difference between the x and y coordinates, and putting it in the rise/run format, you can easily find the slope of the line
Answer:
3.6
Step-by-step explanation:
The average of 9 scores is x.
average = (sum of scores)/(number of scores)
x = (sum of scores)/9
sum of scores = 9x
The sum of the 9 scores is 9x.
The tenth score is 36 more than x, so it is x + 36.
The sum of the 10 scores is 9x + x + 36 = 10x + 36.
The average of the 10 scores is (10x + 36)/10 = x + 3.6
The difference of averages is
x + 3.6 - x = 3.6
