1. Suppose you spin the spinner shown below, which is divided into equal parts. What is the probability the pointer lands on a number that is a
multiple of 9?
A 1 out of 8
B 1 out of 4
C 2 out of 3
D out of 3

Solve 13 + w/7= -18 (w/7 is a fraction)

Isaac wants the equation below to have no solution when the missing number is placed in the box. which number should he place in the box?

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.
