Four friends are sharing a pizza. One friend eats half of the pizza. The other three friends equally divide the rest among themselves. What portion of the pizza did each of the other three friends receive?
A. 1/5
B. 1/3
C. ¼
D. 1/6
We assume the pizza to be full representing 1. One friend eats ½ of 1=1/2
The remaining portion of the pizza=1-1/2=2/2-1/2=1/2
Three friends share equally ½ of the pizza=1/2÷3=12*13=1/6
Therefore, the Correct Answer is D.

Q #3: Elevation above sea level and temperature are negatively-correlated variables. Which of the following statement describes the relationship between the variables?
A. As elevation decreases, temperature remains the same
B. As elevation decreases, temperature decreases
C. As elevation increases, temperature decreases
D. As elevation increases, temperature increases
Answer Explanation
In a negatively-correlated variables, a change in one variable result in opposite change in the other variable. In other words, an increase in on variable results in a decrease in the other.
Now let’s analyze the given scenarios:
As elevation decreases, temperature remains the same this is NO-CORRELATION
As elevation decreases, temperature decreases is a POSITIVE CORRELATION
As elevation increases, temperature decreases is a NEGATIVE CORRELATION
As elevation increases, temperature increases is a POSITIVE CORRELATION
