HBO recently published a report detailing the watch-time of all its active users. It was identified that the monthly watch-time follows a normal distribution with a mean of 102 hours and a standard deviation of 10 hours. a. What is the probability that a randomly selected subscriber watches more than 87 hours of HBO per month? Answer in exact fraction, or rounded to at least 4 decimal places. b. What is the probability that a randomly selected subscriber watches between 97 and 103 hours of HBO per month? Answer in exact fraction, or rounded to at least 4 decimal places.

You have the formula y = 3x + 12. Calculate x then y = 45. Basic level 2) A mini submarine is to be used to investigate a shipwreck that lies deep on the ocean floor. The mini submarine starts from the surface of the sea and then travels downwards with the vertical speed of 0.50 meters per second. Let y be the submarine's depth in meters below the surface when it traveled for x seconds. The depth is given as a negative number, for example -4 m when it is 4 meters below the surface. a) Determine a formula that shows how y depends on x. b) Use the formula to calculate the submarine's depth after an hour's travel.

In going from Chicago to Atlanta, a car averages 45 miles per hour, and in going from Atlanta to Miami, it averages 55 miles per hour. If Atlanta is halfway between Chicago and Miami, what is the average speed from Chicago to Miami? Discuss an intuitive solution. Write a paragraph defending your intuitive solution. Then solve the problem algebraically. Is your intuitive solution the same as the algebraic one? If not, find the flaw.
You want to estimate how many fish there are in a small pond. Let's suppose that you first capture n1=500 fish, tag them, and throw them back into the pond. After a couple of days you go back to the pond and capture n2=120 fish, of which k=30 are tagged. Estimate the number of fish in the pond. There are approximately Answer fish in the pond.
Akira is running around a circular track. Akira runs counterclockwise. From where he starts, it takes him 22 seconds to reach the easternmost point of the track. It takes him 95 seconds to run one complete lap.Bob starts running at the same time as Akira. Bob starts from the northernmost point and runs clockwise. Bob and Akira pass each other for the first time after 26 seconds. How long does Bob take to run one lap of the track? The answer to this question should be the amount of time in seconds rounded to four decimal places that it takes for Bob to run a complete lap around the circular track.

I bought a new gas lawn mower the other day. This new mower mows faster than the old electric (environmental) one. Why, you ask? It is because the old mower cut a 21 inch path, while the new one cuts a 22 inch path. So how much time did I save? Look at some facts. My lawn is a rectangle measuring 150 feet by 105 feet I mow the lawn in strips and always in the same direction (length or width) My walking speed is 120 feet/minute It takes 5 seconds to turn around after each strip How much time did I save if I mow back and forth along the width or if I mow back and forth along the length? Pick one and figure it out. My neighbor does not like minutes the noise it makes, but I do!
