Mrs. ibarra wants to create a right triangle for a geometry test. she plans to use 15, 36, and 41 as side lengths. which statements should she consider to determine whether it will be a right triangle? check all that apply.

a.15 + 36 > 41, so the side lengths will form a triangle
b.15 + 36 does not equal 41, so the side lengths will not form a triangle
c.15^2 + 36^2 = 1521
d.41^2 = 1681
e. since a^2 + b^2 does not equal c^2, it will not equal a right triangle
f.15^2 + 36^2 = 297
g.41^2 = 82

select all that apply, you!

Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is $45,000 with a standard deviation of $9,200. for a sample of 25 subscribers to plan b, the mean income is $64,300 with a standard deviation of $7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule? (negative amount should be indicated by a minus sign. round your answer to 3 decimal places.) compute the value of the test statistic. (negative amount should be indicated by a minus sign. round your answer to 2 decimal places.) what is your decision regarding h0 ? reject h0 fail to reject h0 compute the p-value. less than 0.01 between 0.01 and 0.025 between 0.025 and 0.05 between 0.05 and 0.10 greater than 0.10
