Question 1170956: Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 243 feet and a standard deviation of 42 feet.
Use your graphing calculator to answer the following questions. Write your answers in percent form. Round your answers to the nearest tenth of a percent.
a) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 228 feet?
P (fewer than 228 feet) = %
b) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled more than 246 feet?
P(more than 246 feet) = %

Question 1174786: I do not know if the topic I choose is correct.
But the question and directions are: Write the given expression as an equivalent rational expression that has the given denominator.
 The denominator needs to be: (2-x)(x^2+9)
I pulled out the 3 from both top and bottom and cross canceled making the expression: 
But I do not know how to get rid of the -1 on the bottom to make the denominator (2-x)(x^2+9) and I know you have to multiply by (x^2+9) on both the top and bottom but I don't know how to get ride of the -1.
