Answer: A Yes, because the balls are randomly selected, the distances of the new ball can be compared to the distances of the original ball.
B Yes, because the original ball type is included in this experiment, the distances the different balls travel can be accurately compared.
Step-by-step explanation:
C No, because a placebo ball was not used, a comparison cannot be made to determine if the new ball travels significantly farther.
D No, because all of the new type of balls are not hit first, the distances they travel cannot be compared to the distances of the original ball.
In a week, the parlor would make about $300 from milkshakes
The total amount the ice cream parlor makes in a week is dependent is the product of the number of days in a week , the number of milkshakes sold in a day and the price of a milkshake.
Total amount = number of milkshakes sold in a week x price of a milkshake
There are 7 days in a week, in a week the parlor would sell : 11 x 7 = 77 milkshakes
price of a milkshake = $3.99
77 x $3.99 = $307.23
