(a) To determine To graph: The solution of quadratic equation x 2 − 2 x < 15 and graph the solution on number line. Explanation Given: The quadratic equation, x 2 − 2 x < 15 Graph: Since, quadratic equation is, x 2 − 2 x < 15 Rewrite the inequality so that all the terms are on the left side and 0 is on the right side. Adding − 15 to both sides Rewriting the equation, x 2 − 2 x − 15 < 0 Put x 2 − 2 x − 15 = 0 to find x -intercepts and solve for x , x 2 − 2 x − 15 = 0 x 2 − 5 x + 3 x − 15 = 0 x ( x − 5 ) + 3 ( x − 5 ) = 0 ( x + 3 ) ( x − 5 ) = 0 This equation results to, Either, ( x + 3 ) = 0 x = − 3 Or ( x − 5 ) = 0 x = 5 Above quadratic equation has three regions divided by the above value of x (b) To determine To graph: The Solution of quadratic equation 2 x 2 − 3 x − 20 < 0 and graph the solution on number line.

The height of the graph of the probability density function f(x) varies with X as follows (round to four decimal places): X 16 Height of the Graph of the Probability Density Function You are flying out of Terminal 3 at JFK on a Wednesday afternoon between 3:00 and 4:00 PM. You get stuck in a traffic jam on the way to the airport, and if it takes you longer than 12 minutes to clear security, you'll miss your flight. The probability that you'll miss your flight is You have arrived at the airport and have been waiting 10 minutes at the security checkpoint. Recall that if you spend more than 12 minutes clearing security, you will miss your flight. Now what is the probability that you'll miss your flight? ○ 0.5 O 0.25 ○ 0.8333 ○ 0.6667
