Determine whether the two triangles are congruent. If they are congruent, state by what theorem (SSS, SAS, or ASA) they are congruent. Let a = 111, c = 39, x = 7, d = 111, f = 39, and y = 7. a. Yes, the two triangles are congruent by the SSS Theorem.
b. Yes, the two triangles are congruent by the SAS Theorem.
c. Yes, the two triangles are congruent by the ASA Theorem.
d. No, the two triangles are not congruent.

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.
