Participants were randomly assigned to one of three groups. Participants in the first group engaged in Exercise Program A, participants in the second group participated in Exercise Program B, and the third group compared participated in Exercise Program C. Which statistical tests should the researchers use to compare the mean pulse rates from each group

One-way ANOVA test.

Step-by-step explanation:

In this case, the participants were randomly assigned to one of three groups:

A z-test or a t-test is used when we need to test the significance of the difference between two group means.

A One-way ANOVA test is used to determine whether there is significant difference between the means for more than two groups.

Thus, a One-way ANOVA test can be used to compare the mean pulse rates from each group.

i think it is x = 1.2

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
