Suppose a car is traveling down the highway at a constant rate of 60 miles per hour. It passes a police car at the side of the road. To catch up to the car, the police officer accelerates at a constant rate. The distance d (in miles) the police car has traveled as a function of time t (in hours) since the other car has passed it is given by d=360t^2. Write and solve a system of equations to calculate how long it takes the police car to catch up to the other car.​

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
