Determine whether the equation defines y as a function of x.x2 + y = 36

Solve the linear inequality. Other than ∅, use interval notation to express the solution set and graph the solution set on a number line.-4x ≥ 32

Evaluate the function at the given value of the independent variable and simplify. f(x) = ; f(-4)  

A public address speaker is placed against a wall and therefore emits all its sound energy hemispherically. When a test tone is played through the speaker, it produces  an intensity level of 140 dB (ouch!) at a distance of 1.00 meter from the speaker.  a) What is the sound power emitted by the speaker? b) At what distance from the speaker would the intensity level be 120 dB?

Because not all airline passengers show up for their reserved seat, an airline sells 228 tickets for a flight that holds only 200 passengers. The probability that a passenger does not show up is 0.09, and the passengers behave independently. If you wanted to determine the probability that the flight departs with at least one empty seat, what would be the best definition of the random variable you would use?

Students are randomly assigned to one of nine teams in a class.  They are equally likely to be assigned to any team.   X is the team to which a student is assigned; x = 1, 2, 3, 4, 5, 6, 7, 8, 9.  Determine the population standard deviation of X. This question is copywritten by Arizona State University and Linda Chattin.  It may not be posted to any website, may not be texted to anyone, and may not be screenshot or photographed.  If your answer is non-integer, express it to three decimal places.

Would you rather have a pet dinosaur (any type!) or a pet dragon?  Part A (Text Box Below):Tell me your choice and explain why in the text box below. Part B (On Your Paper): Draw your new pet and give it a name! Don’t worry — I’m not expecting a masterpiece (this is a math class, after all). Just have fun with it!

Scenario 3.1Tony is about to participate in his first 10K run. One of his friends told him to make sure to “carbo load” and to take a niacin supplement before the race. Tony had heard the term “carbo loading” before but was not sure why it was necessary and had no idea why he would need a niacin supplement. He had been training for months and was confident that he would finish the race easily and, therefore, did not heed his friend’s advice. On the day of the race, Tony was so excited it felt like he was flying through the first half of the race. Tony wanted to beat his current best time and was nearing the end of the race when he decided to pick up his pace to the finish line. Unfortunately, Tony became fatigued and had to walk to the finish line out of breath and with his muscles burning.Refer to Scenario 3.1. Could Tony’s excitement before the race have caused him to become fatigued toward the end of the race?
