Consider the example of a company that is interested in better understanding the number of orders it
receives. Let X = the number of orders per week. The data is in the following table:
Value (X) 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 |
Probability P(x) .03 | .10 | .15 | .17 | .25 | .15 |
.10 | .05 |

2. Is X discrete or continuous? Explain.

3. Is this a valid probability distribution? Explain.

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 3 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30∘c on monday, but decreased at a constant rate in the next 3 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.
