Use the image below to answer the following question: A right triangle is shown. The two angles that are not 90 degrees are marked x and y. The leg across from angle y measuring 9, another leg across from angle x measuring 12, and the hypotenuse measuring 15.

What relationship do the ratios of sin y° and cos x° share?

The ratios are both identical. (9 over 15 and 9 over 15)
The ratios are opposites. (negative 9 over 15 and 9 over 15)
The ratios are reciprocals. (9 over 15 and 15 over 9)
The ratios are both negative. (negative 15 over 9 and negative 9 over 15)

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.
