Wait time for 911 calls. The wait time before a 911 call is answered in the state of California has a probability density function
a. The state standard is that 90% of 911 calls are to be answered within 10 sec. Verify that this standard is met using the probability density function f.
b. What is the probability that a 911 call is answered within 15 to 25 sec after being made?

- A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.m. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 10.7 gallons. What is the average rate of flow of the gasoline into the gas tank?arrow_forwardUse the table of values you made in part 4 of the example to find the limiting value of the average rate of change in velocity.arrow_forwardFind the values of x in each proportion: a x6=3x c 6x+4=2x+2 b x53=2x37 d x+35=x+57 e x2x5=2x+1x1 g x1x+2=103x2 f x(x+5)4x+4=95 h x+72=x+2x2arrow_forward
- Determine whether the following function is a probability density function. f(x) = x, 0sxs8 32 Is the function f(x) a probability density function? No Yesarrow_forwardShow full solution.According to rainfall data collected by a laboratory during storm events, the precipitation level in inches (X) varies jointly with runoff in cubic feet per second (Y). The joint probability mass function (PMF) of both variables are given by the following Table: Y 1 2 3 10 0.05 0.15 0 20 0.1 0.25 0.25 30 0 0.1 0.1 a. What is the probability that the next storm will bring a precipitation of 2 or more inches and a runoff of more than 20 cfs?b. After a storm, a precipitation of 2 inches is measured. What is the probability that the runoff in this storm is 20 cfs or more?c. Are X and Y statistically dependent?
