Trains headed for destination A arrive at the train station at 15-minute intervals starting at 7 A.M., whereas trains headed for

destination B arrive at 15-minute intervals starting at 7:05 A.M. (a) If a certain passenger arrives at the station at a time uniformly distributed between 7 and 8 A.M. and then gets on the first train that arrives, what proportion of time does he or she go to destination A

Answer:

  2/3

Step-by-step explanation:

In the 5-minute interval between 7:00 and 7:05, a train to B is the first to arrive. In the 10-minute interval between 7:05 and 7:15, a train to A is the first to arrive. That is, in any 15-minute interval, the probability is 10/15 = 2/3 that a train to A is the first to arrive.

The 1-hour interval between 7 A.M. and 8 A.M. is an integer number of such intervals, so ...

  2/3 of the time, he or she will go to destination A.

Tanya [424]

Answer:

Step-by-step explanation:

The answer is going to be 1,462.5$. And that's because 9.75% of 500$=48.75$. So we just multiply 48.75 by 30 which signifies 30 years. So the workout gives us the solution; 48.75*30=1,462.5.

Determine whether each set of numbers can be measure of the sides of a RIGHT triangle. Justify your answer.
Papessa [141]

Answer:

The side lengths cannot belong to a right triangle.

Step-by-step explanation:

This is a simple case of Pythagorean proof. If this triangle was a right triangle, 20^2 + 21^2 = 28^2. However, this is not the case. 20^2 + 21^2 = 841, which square root is 29.

If you forgot, the Pythagoren Theorem is: a^2 + b^2 = c^2.

Hope this helps!

Can someone PLEASE explain to me how to find the rule of a function table. I understand how find the rule of easy function table
goldfiish [28.3K]

Answer:

y=2x-46

Step-by-step explanation:

Select any two coordinate points. I'm picking (1,-44) and (2, -42).

x1 and y1 are the first coordinates. x2 and y2 are the second coordinates. The formula for finding the slope of a linear fuction is (y2-y1)/(x2-x1). Substiute the numbers into this formula:

-42-(-44)/2-1

=-42+44/1

=2

This is the slope. In y=mx+b, plug in your newly found slope. Next, to find the y-intercept, plug any pair of coordinate points into your incomplete formula y=2x+b. I'm going to use (1,-44) again.

-44=2(1)+b

-44=2+b

b=-46

Now, plug this into your formula, and you'll get y=2x-46.
