A major traffic problem in the Greater Cincinnati area involves traffic attempting to cross the Ohio River from Cincinnati to Kentucky using Interstate 75. Let us assume that the probability of no traffic delay in one period, given no traffic delay in the preceding period, is 0.85 and that the probability of finding a traffic delay in one period, given a delay in the preceding period, is 0.75. Traffic is classified as having either a delay or a no-delay state, and the period considered is 30 minutes.
a. Assume that you are a motorist entering the traffic system and receive a radio report of a traffic delay. What is the probability that for the next 60 minutes (two time periods) the system will be in the delay state? Note that this result is the probability of being in the delay state for two consecutive periods. If required, round your answer to three decimal places.
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.
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
[tex]0.85x + 0.25(1 - x) = x[/tex]
[tex]0.6x + 0.25 = x[/tex]
[tex]0.4x = 0.25[/tex]
[tex]x = \frac{0.25}{0.4}[/tex]
[tex]x = 0.625[/tex]
0.625 = 62.5% probability that in the long run the traffic will not be in the delay state

16. Kim spends 10 minutes washing her car. Denzel spends 3 times as many minutes (d)
washing his car as Kim spends.
Part A
Which equation can be used to find how many minutes Denzel spends washing
his car?
A.
10 + 3 = d
B.
10 3 = d
C.
10- 3 = d
D. 10 = 3 = d
Answer:
B
Step-by-step explanation:
10x3= 30
because kim spends 10 min washing her car, and Denzel spends 3 x as a many washing his car.
so you do 10 x 3 = 30
The equation that represents the time Denzel spends is d = 10×3.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, Kim spends 10 minutes washing her car and Denzel spends 3 times as many minutes (d) washing his car as Kim spends.
∴ The equation that represents the time Denzel spends is d = 10×3.

the following data points represent the number of spots on each giraffe that lives in the Curran plains find the median 174,226,236,231,203,185,194,221,197 find the median
The required median number of spots on giraffes in the Curran plains is 203.
What is Median?A data set's median value is the place where 50% of the data points have values that are lower or equal to it, and 50% of the data points have values that are higher or equal to it. To organize the data points in increasing order for a small data set, count the number of data points (n).
According to question:To find the median, we need to first sort the data points in ascending order:
174, 185, 194, 197, 203, 221, 226, 231, 236
Since there are an odd number of data points, the median is the middle value, which in this case is 203.
Therefore, the median number of spots on giraffes in the Curran plains is 203

Answer:
A
Step-by-step explanation:
Source:
Trust me bro
The theorem used to prove the three triangles are similar is the ASA similarity theorem. The correct option is A.
What is the similarity?If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.
According to the ASA rule, two triangles are said to be congruent if any two angles and the side included between the angles of one triangle are equal to the corresponding two angles and the side included between the angles of the second triangle.

equation to fit the pattern x 24 32 40 48 and y 6 8 10 12
Answer:
y = 1/4(x)
Step-by-step explanation:
Given the equation:
x 24 32 40 48
y 6 8 10 12
The slope = (y2 - y1) / (x2 - x1)
Slope = (12 - 6) / (48 - 24)
Slope = 6 / 24
Slope = 1 / 4
The slope intercept relation is expressed thus :
y = mx + c
m = slope ; c = intercept
Picking a point :
x = 32, y = 8
8 = 1/4(32) + c
8 = 8 + c
c = 0
Hence, the fit pattern for the equation is :
y = 1/4(x)

Step-by-step explanation:
Given
See attachment
Required
Find b, c and d
First, we solve for b using:
[tex]b + 10 + b - 10 = 180[/tex] --- base angles of a parallelogram
Collect like terms
[tex]b + b =180+10-10[/tex]
[tex]2b = 180[/tex]
Solve for b
[tex]b = 180/2[/tex]
[tex]b = 90[/tex]
Then, we have:
[tex]d =b + 10[/tex]
[tex]c = b - 10[/tex] --- opposite angles
So, we have:
[tex]d =90 + 10[/tex]
[tex]d =100[/tex]
[tex]c = 90 - 10[/tex]

A cylindrical storage tank has a depth of 5 ft and a radius measuring 3 ft. The tank needs to be painted. If 1 pint of paint covers 50 ft2 and you can only purchase full pints of paint, how many pints must be purchased to paint the exterior of the storage tank? (Use your calculator value of . Round your answer up to the nearest whole number.)
Answer:
4 pints
Step-by-step explanation:
Well to figure this one out we need the surface area of the cylinder
The formula is : SA=2πrh+2πr^2
Don't worry about memorizing most of these formula's except the basic ones for Surface area and Volume in a test the formula's will be given but I do recommend practicing them
Any way lets keep going
Depth of 5ft basically means 5ft in height (to let you know)
2*pi*3*5+2*pi*3^2
SA=150.796447372 ft^2 rounded is basically 151
any way we know one pint paints 50 ft^2
so 151/50 is 3 remainder 1 so you will need 4 pints except you will barley use 1 pint

There are 12 pink, 9 orange, 6 green and 27 blue. If all the bracelets were used, about what percent of the participants ended up with orange bracelets?
Answer:
About 16.67% of the participants ended up with orange bracelets.
Step-by-step explanation:
The percentage of orange bracelets is given by the number of orange bracelets multiplied by 100% and divided by the total number of bracelets.
In this question:
Total of 54 bracelets.
9 orange.
So
9*100%/54 = 16.67%
About 16.67% of the participants ended up with orange bracelets.

What is the value of x in this octagon?
Enter your answer in the box.
Answer: 166 degrees
Step-by-step explanation:
An octagon has 1080 degrees in it. So just subtract all of the angles out of 1080.
1080-104-126-163-130-131-107-153= 166
ANSWER: 166 degrees
Answer:
166 degrees
Step-by-step explanation:
in an octagon, there are a total of 1080 degrees,
so we take all of the degrees we do know, and subtract them from 1,080 degrees! --- (1080-104-126-163-130-131-107-153= 166)
we end up with 166 degrees! :)
