Graphs A and B are the result of combining two linear functions, f(x) and g(x). The functions were combined by addition to form h(x), and then multiplication to form j(x). ANSWER: Graph B represents j(x).
The y-intercepts of f(x) and g(x) can be –1 and 6.

The function models the number of accidents

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.
