Answer:A device tests whether each blinker on a car is functioning properly. A company estimates that 2.8% of blinkers that they produce are defective. The device is 98% accurate for blinkers that are functioning properly and 96% accurate for blinkers that are defective. You use the device to test a randomly selected blinker. What is the probability that the test result is correct?
Step-by-step explanation:SRRY had to meme a little bit it's 40%
No she is not correct if she said 200+20+23 was the same as 200+40+3 she would have been correct.
Answer:
Angle F = 140°
Step-by-step explanation:
Add up all the angles and set it equal to 720°
x-20+x-40+x-60+130+120+110=
720
Add the x's together. And the numbers together.
3x - 120 + 360 =720
3x + 240 = 720
Subtract 240.
3x = 480
Divide by 3.
x = 160
Now find Angle F.
F = 160 - 20
F = 140°
The answer is B. 12 inches
