4. complete the table(10 points: 1 point for each row)
a. identify the actual number of sales at each price
b. use your line of best fit to calculate the predicted sales at each price
c. calculate the residuals at each price by subtracting predicted sales from actual sales
5. create a residual plot using the data from the table

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

two data sets with the same median will not have the same varaibility
