Select all the true statements for the figures shown. If ∠E ≅ ∠B, then the triangles are congruent by the SAS Triangle Congruence Theorem.

If ∠F is a right angle, then the triangles are congruent by the HL Triangle Congruence Theorem.

If m∠D + m∠E = 90, then m∠F = 90. The triangles are congruent by the HL Triangle Congruence Theorem.

If m∠D + m∠E = 90, then m∠F = 90. The triangles are congruent by the SSA Triangle Congruence Theorem.

If m∠D = 37, then m∠A = 37. The triangles are congruent by the AAS Triangle Congruence Theorem.

The measure of an angle is 117°. what is the measure of a supplementary angle?

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
