An ecologist selected a random sample of 30 prairie dogs from a colony and found that the mean mass of the prairie dogs in the sample was 0.94  kilograms (kg)  with an associated margin of error of  0.12kg. Which of the following is the best interpretation of the ecologist's findings?

Note:
There are many concepts and definitions used in solving this question. The student must be familiar with mean, sampling, random sample, margin of error and hoe any results derived from the sample relate to the population, to solve this problem correctly.

The table above shows selected values for the function h . In the x y -plane, the graph of y = h(x) h  is a line. What is the value of (8)  ?

Note:
After finding the equation y = 2x + 3 , we can verify it by putting the third point in the equation and check if it lies on the line, that is, the third point which is   lies on 

So, the equation   is the graph of .
