Question

do not linger over problems that take too much time. solve as many as you can; then return to the others in the time you have left for this test. you are permitted to use a calculator on this test. you may use your calculator for any problems you choose. 1. marine biologists collected a sample of 40 adult sea turtles from hammerhead bay and estimated the age, in whole years, of each turtle. the histogram below shows the frequency of sea turtles for each of the estimated age groups. what is the maximum possible number of sea turtles that could have had an estimated age of 45 years? estimated ages of sea turtles in hammerhead bay

Explanation:

Step1: Identify the age - group containing 45 years

The age of 45 years falls within the age - group 39.5 - 49.5.

Step2: Analyze the frequency of the age - group

The frequency of the age - group 39.5 - 49.5 is 12.

Step3: Determine the maximum number

Since all the turtles in the 39.5 - 49.5 age - group could potentially be 45 years old (to maximize the number), the maximum number of sea turtles that could have an estimated age of 45 years is 12.

Answer:

12
