For δabc, ∠a = 8x - 10, ∠b = 10x - 40, and ∠c = 3x + 20. if δabc undergoes a dilation by a scale factor of
1
2
to create δa'b'c' with ∠a' = 6x + 10, ∠b' = 70 - x, and ∠c' =
10x
2
, which confirms that δabc∼δa'b'c by the aa criterion?

Apolice office claims that the proportion of people wearing seat belts is less than 65%. to test this claim, a random sample of 200 drivers is taken and its determined that 126 people are wearing seat belts. the following is the setup for this hypothesis test: h0: p=0.65 ha: p< 0.65 find the p-value for this hypothesis test for a proportion and round your answer to 3 decimal places.
