When the light turns yellow, should you stop or go through it? an article defines the “indecision zone” as the period when a vehicle is between 2.5 and 5.5 seconds away from an intersection. at the intersection of route 7 and north shrewsbury in clarendon, vermont, 154 vehicles were observed to encounter a yellow light in the indecision zone, and 23 of them ran the red light. at the intersection of route 62 and paine turnpike in berlin, vermont, 183 vehicles entered the intersection in the indecision zone, and 20 ran the red light. can you conclude that the proportion of red-light runners differs between the two intersections? find the p-value and state a conclusion. round the answer to four decimal places.

step-by-step explanation:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
