Lower quartile (xL): 27
Upper quartile (xU): 65

There would be 2 in each group. 12/6=2.
Answer: (9+10x)(9-10x). Explanation: To factor this, look for numbers that can be FOILed (first, outer, inner, last). You know what if you separate the equation into two different parenthesis, one has to be negative and the other positive because there are no x^1 variables. 81 is equal to 9*9, and 100x^2 is equal to 10x*10x. Split these into two parenthesis, and add corresponding negatives. The answer should be (9+10x)(9-10x).
Graph 1 is related to table C because the first 3 values are increasing, and the 4th value decreases. Or because at 1PM, 3PM, and 5PM, the temperature was increasing, but at 7PM the temperature decreased. Graph 1 shows the first 3 points increasing, and then decreasing at the 4th point.
Graph 2 is related to table A because as the time increases/goes on, the temperature decreases exponentially/continues to decrease at a higher rate than before. From 1-3PM the temperate decreases by 2°F, from 3-5PM it decreased by 8°F, from 5-7PM the temperature decreased by 17°F.
Graph 3 is related to table B because as the time increases/goes on, the temperature decreases at a steady rate of 1°F every 2 hours.
First, you try to make sure that both the denominators are the same. In order to do this, you multiply both fractions' numerator and denominator by the other fraction's denominator. Next, you combine like terms in the numerator, and then you simplify the fraction.
