Solve the compound inequality. Other than ∅, use interval notation to express the solution set and graph the solution set on a number line.9 < 3x ≤ 21

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!
