Suppose a weather forecast reports that the probability of snow this week is 0.18. The forecast states that if it snows this week, the probability that it snows next week is 0.29. If it does not snow this week, the probability that it snows next week is 0.12. The tree diagram depicts the possible weather event outcomes with the associated probabilities.

What is the spring constant of a spring that is compressed 0.2 m and has 1.50 J of elastic potential energy stored in it?

Determine the elastic potential energy stored in a spring with a spring constant of 125 N/m that is compressed 0.75 m.

Two dice are thrown simultaneously. The probability of obtaining a total score of 5 is

A spring with constant k = 800 N/m is compressed 12 cm from its equilibrium position. A spring with spring constant k = 400 N/m has the same elastic potential energy as the first spring when it extension is?

How much does a spring with a spring constant of 400 N/m need to be compressed in order to store 8.5 J of elastic potential energy?

At Cal’s Computer Warehouse, Cal wants to know the probability that a customer who comes into his store will buy a computer or a printer.  He collected the following data during a recent week:  233 customers visited the store, 126 purchased computers, 44 purchased printers, and 93 made no purchase.
