1. The manager of an ice cream store recorded the order of the first 20 people who entered his store. The results are shown.
9 people choose chocolate ice cream
• 8 people choose vanilla ice cream
• 3 people choose strawberry ice cream
If the ice cream store has 80 customers, which prediction is best
supported by the data?

A : the number of chocolate ice cream orders will be 3 times the number of strawberry ice cream orders

Step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

answer: 12   they all have at least 28 days
