Answer:

∠TUY = 120°

Step-by-step explanation:

There are two rules you can apply here:

1) The sum of the angles inside a triangle is 180°.  This means that ∠SUT = 180° - 70° - 50 ° = 60°

2) A vector coming out of a line two angles between itself and the line, and they add up to 180° as well. This means that ∠TUY = 180° - ∠SUT.  So ∠TUY = 180° - 60° = 120°

So the missing angle one hundred and twenty degrees.

A major traffic problem in the Greater Cincinnati area involves traffic attempting to cross the Ohio River from Cincinnati to Ke
yaroslaw [1]

Answer:

a. 0.563 = 56.3% probability that for the next 60 minutes (two time periods) the system will be in the delay state.

b. 0.625 = 62.5% probability that in the long run the traffic will not be in the delay state

Step-by-step explanation:

Question a:

The probability of finding a traffic delay in one period, given a delay in the preceding period, is 0.75.

The system currently is in traffic delay, so for the next time period, 0.75 probability of a traffic delay. If the next period is in a traffic delay, the following period will also have a 0.75 probability of a traffic delay. So

0.75*0.75 = 0.563

0.563 = 56.3% probability that for the next 60 minutes (two time periods) the system will be in the delay state.

b. What is the probability that in the long run the traffic will not be in the delay state? If required, round your answers to three decimal places.

If it doesn't have a delay, 85% probability of continuing without a delay.

If it has a delay, 75% probability of continuing with a delay.

So, for the long run:

x: current state

85% probability of no delay if x is in no delay, 100 - 75 = 25% if x is in delay(1-x). So

0.85x + 0.25(1 - x) = x

0.6x + 0.25 = x

0.4x = 0.25

x = \frac{0.25}{0.4}

x = 0.625

0.625 = 62.5% probability that in the long run the traffic will not be in the delay state

What is the reciprocal of 2 and 3/8
Leviafan [203]
To find the reciprocal of a number or fraction, just flip the numerator and denominator. Whole numbers are always over 1. 

 2 = \frac{2}{1}

The reciprocal of \frac{2}{1} =  \frac{1}{2} or .5 (one-half)

The reciprocal of \frac{3}{8} =  \frac{8}{3}
