Maurice is cutting out shapes for a class project. He has a scrap of green poster board in the shape of a triangle, shown below.
72 cm
He wants to trim the large green triangle into a smaller triangle by cutting along the dotted line shown. If the red segment along the
left side of the triangle measures 60 cm and the blue segment along the bottom of the triangle measures 108 cm, what is the length
of poster board that Maurice cut?
A
18 cm
OB. 40 cm

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.
