Triangle rst is congruent to triangle .

which sequence of transformations could have been used to transform triangle rst to produce triangle ?

choose exactly two answers that are correct.

a.
triangle rst was reflected across the x-axis and then rotated 90° clockwise around the origin.

b.
triangle rst was reflected across the x-axis and then reflected across the y-axis.

c.
triangle rst was rotated counterclockwise 90° around the origin and then reflected across the x-axis.

d.
triangle rst was translated 8 units right and then reflected across the x-axis.

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.
