A stop light has the following cycle green for 50 seconds yellow for 4 seconds and red for 62 seconds if you arrive at the light 50 times predict how many times you will have to stop and wait more than 4 seconds

the road user will have to wait for more than 4 seconds 17times

Step-by-step explanation

The red signal is for stop and the probability of it happening is 1/3 for the first time.

For 50 times it will be (1/3)× 50 = 16.666667

Hence the road user will have to wait for more than 4 seconds 17times

the distance between point a and point b is 6 units

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
