Answer:

13,000 ft.

Step-by-step explanation:

X -------10960----------C---------------D---------------Y

The entire race (from X to Y) is 7 miles. There are 5,280 ft. in one mile, so 7 miles is 36960 ft.

If we subtract 10,960 from 36,960, then we get the distance from C to Y.

36960-10960 = 26000

They tell you D is at the midpoint between C and Y

So if we divide 26,000 by 2, then we know the distance from C to D and from D to Y.

26000/2 = 13000

The checkpoints are C and D, so the distance between them is 13,000 ft.

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 9 m

LenaWriter [7]

Answer:

52.78% probability that a randomly selected passenger has a waiting time greater than 4.25 minutes.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X greater than x is given by the following formula.

$P(X > x) = \frac{b-x}{b-a}$

Uniformly distributed between 0 and 9 minutes.

This means that $a = 0, b = 9$

Find the probability that a randomly selected passenger has a waiting time greater than 4.25 minutes.

$P(X > 4.25) = \frac{9 - 4.25}{9 - 0} = 0.5278$

52.78% probability that a randomly selected passenger has a waiting time greater than 4.25 minutes.

What are the x-intercepts of this graphed function

igomit [66]

Answer:

B) x-intercepts: (-5,0),(4,0); y-intercept: (0,-2)

Step-by-step explanation:

The x-intercepts of a function are where the graph passes through the x-axis, which are (-5,0) and (4,0)

The y-intercept of a function is where the graph passes through the y-axis, which is (0,-2)

Therefore, B is the correct answer
