The graph shows the functions f(x), p(x), and g(x): graph of function f of x is y is equal to 4 plus the quantity 1.5 raised to the power of x. the straight line g of x joins ordered pairs 1, 3 and 3, negative 1 and is extended on both sides. the straight line p of x joins the ordered pairs 5, 0 and 6, 3 and is extended on both sides. courtesy of texas instruments part a: what is the solution to the pair of equations represented by p(x) and g(x)? (3 points) part b: write any two solutions for g(x). (3 points) part c: what is the solution to the equation g(x) = f(x)? justify your answer. (4 points)

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.
