8. Peter and his partner are conducting a physics experiment on pendulum motion. Their 30-cm pendulur traverses an arc of 15 cm. To the nearest degree, how many degrees of rotation did

the pendulum swing?

What is the measure of angle afe? 79 81 91 99

Which fraction is equal to 1hole and 2/5? a.3/5 b.75 c.57 d.73

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
