Answer:
∠C=90°
∠A=67°
∠B=23°
Step-by-step explanation:
For angle C:
Thales' Theorem states that an angle inscribed across a circle's diameter is always a right angle.
Therefore, since AB is the diameter(hypotenuse) then angle C is the right angle. (90°)
For Angle A:
The measure of arc BC= 134 degrees. We can just use a formula for an inscribed triangle. ∠A = 1/2 (mBC)
∠A= (1/2)134
∠A= 77°
For angle B:
All triangle angles all add up to 180. We can just subtract angles A and C from 180°:
∠B = 180-(90+67)
∠B = 23°

Answer:
Both ordered pairs are solutions to this equation.
Step-by-step explanation:
If you plug in the x and y values given in the ordered pair, you make the left side of the equation equal the right for both pairs.

Answer:
1.28
Step-by-step explanation:
Given that a sample of 1500 computer chips revealed that 55% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 53% of the chips do not fail in the first 1000 hours of their use.
(Two tailed test for testing sample proportion with population proportion)
Std error of proportion assuming p = 0.53 is
p difference = 0.02
Z= test statistic = p diff/std error = 1.2775~1.28
