Estimating Ice Cream Sales

The video tutorial explains how to use the function of the best fit line to predict the number of ice cream cones sold on a 70° day. It involves analyzing a plot to locate the 70° mark, finding where it intersects with the best fit line, and estimating the corresponding value, which is between 250 and 300, approximately 275. The tutorial emphasizes rounding the answer to the nearest whole number.

What is the purpose of using the best fit line in this context?

• To find the average temperature over a week.

• To predict the number of ice cream cones sold.

• To calculate the total sales revenue.

• To determine the exact temperature on a given day.

How many degrees does each tick mark represent on the plot?

• 2 degrees

• 5 degrees

• 10 degrees

• 15 degrees

Where is the 70° mark located on the plot?

• Two tick marks after 50°

• One tick mark before 75°

• Directly at 75°

• Three tick marks after 50°

What is the first step in finding the number of ice cream cones sold on a 70° day?

• Identify the highest temperature on the plot.

• Calculate the average temperature.

• Locate the 70° mark on the plot.

• Estimate the total sales revenue.

What is the estimated number of ice cream cones sold on a 70° day?

• 350 cones

• 250 cones

• 275 cones

• 300 cones

If the intersection point is slightly above halfway between 250 and 300, what is a reasonable estimate?

• 290 cones

• 280 cones

• 260 cones

• 270 cones

Which answer choice should you select if the intersection is closest to 275?

• 275 cones

• 325 cones

• 250 cones

• 300 cones
