Rhonda manages wildlife samples for Ducks Unlimited. Two samples of duck populations at a migratory site are shown in the table
below. Which statement about the samples is true?
A. Rhonda needs to continue taking samples of ducks until both samples have at least one of each type of duck.
B. Rhonda should take a third sample and then use the two that are most representative since these samples vary quite a bit.
C. Rhonda should use both of these samples as they are to make inferences about the average population of each type of duck in the pond.
D. Both samples must be biased because there are more Mallards than any other type of duck recorded in the sample.

Answer:
Step-by-step explanation:
Let x be the number of weeks that it will take Andy to reach his goal.
We have been given that Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles, so number of miles increased in x weeks will be 1.5x and total number of miles ran in x weeks will be 1.5x+12.
Since Andy wants to reach a total of 26 miles per week, so we will equate the total number of miles ran in x weeks with 26.
Therefore, the equation can be used to determine x, the number of weeks that it will take Andy to reach his goal.
