Blue Cab operates 12% of the taxis in a certain city, and Green Cab operates the other 88%. After a night-time hit-and-run accident involving a taxi, an eyewitness said the vehicle was blue. Suppose, though, that under night vision conditions, only 85% of individuals can correctly distinguish between a blue and a green vehicle. What is the probability that the taxi at fault was blue given an eyewitness said it was? Round your answer to 3 decimal places Write your answer as reduced fraction

Answers

Answer 1

The probability that the taxi at fault was blue given an eyewitness said it was is approximately 0.436.

To find the probability that the taxi at fault was blue given an eyewitness said it was, we can use Bayes' theorem. Bayes' theorem is expressed as: P(A|B) = (P(B|A) * P(A)) / P(B)

Where:
- P(A|B) is the probability of A given B (the probability the taxi is blue given the eyewitness said it was blue)
- P(B|A) is the probability of B given A (the probability the eyewitness said the taxi was blue given it was actually blue)
- P(A) is the probability of A (the probability the taxi is blue)
- P(B) is the probability of B (the probability the eyewitness said the taxi was blue)


First, let's define our events:
- A: The taxi is blue (Blue Cab), with a probability of 12% (0.12)
- B: The eyewitness said the taxi was blue

Now, we need to find P(B|A) and P(B).

1. P(B|A) = 0.85 (the probability the eyewitness correctly identifies the blue taxi)
2. P(B) can be found using the law of total probability: P(B) = P(B|A) * P(A) + P(B|A') * P(A')
  - A': The taxi is not blue (Green Cab), with a probability of 88% (0.88)
  - P(B|A') = 1 - 0.85 = 0.15 (the probability the eyewitness incorrectly identifies the green taxi as blue)

So, P(B) = 0.85 * 0.12 + 0.15 * 0.88 = 0.102 + 0.132 = 0.234

Now, we can apply Bayes' theorem:

P(A|B) = (P(B|A) * P(A)) / P(B)
P(A|B) = (0.85 * 0.12) / 0.234
P(A|B) ≈ 0.4359

Rounded to three decimal places, the probability that the taxi at fault was blue given an eyewitness said it was is approximately 0.436 or 436/1000 as a reduced fraction.

A rectangular tank measures 15 cm by 7 cm by 10 cm. How many milliliters of water are in the tank when it is full? How many liters?

Answers

The tank contains 1050 milliliters of water when full or 1.05 liters.

To calculate the volume of the tank in milliliters, we multiply the length (15 cm), width (7 cm), and height (10 cm) together:

15 cm x 7 cm x 10 cm = 1050 cm³

Since 1 milliliter equals 1 cubic centimeter (cm^3), we know that the tank can hold 1050 milliliters of water.

To convert milliliters to liters, we can divide the volume in milliliters by 1000:

1050 mL ÷ 1000 = 1.05 L

Therefore, when full, the tank can hold 1050 milliliters of water or 1.05 liters.

Linda has two cats. The difference in weight of her Maine Coon and Siberian is at least 6 pounds. Linda’s Siberian has a weight of 834
pounds. Choose the inequality that represents the possible weight of the Maine Coon

Answers

The inequality that represents the possible weight of the Maine Coon is 828 ≤ x ≤ 840

Let x be the weight of Linda's Maine Coon in pounds.

Since the difference in weight between the two cats is at least 6 pounds, we can write the following inequality:

|x - 834| ≥ 6

This inequality can be interpreted as "the absolute value of the difference between the weight of the Maine Coon and 834 pounds is greater than or equal to 6".

Simplifying the inequality, we get:

-6 ≤ x - 834 ≤ 6

Adding 834 to each side of the inequality, we get:

828 ≤ x ≤ 840

Therefore, the possible weight of Linda's Maine Coon is between 828 and 840 pounds, inclusive.

165. 1% of 384. 7. Round to the nearest thousandth

Answers

Rounding to the nearest thousandth means rewrite the number and deleting all digits to the right of the rounded number. The percentage value for 165.1% of 384.7 is equals to the 42.917%.

In mathematics, a percentage is a number that represents a fraction of hundred. We have to calculate the value of 165.1% of 384.7. Percentage solution with steps:

Step 1: We make the assumption that 384.7 is 100% since it is our output value.

Step 2: We next represent the value we need with x. From step 1, it follows that 100% = 384.7.

Step 3: In the same sense, x% = 165.1.

Step 5: Now, we have a pair of simple equations:

100% = 384.7 --(1).

x% = 165.1 ---(2).

Step 6: By simply dividing equation (1) by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have 100% /x% = 384.7/165.1.

Step 7: Taking the inverse or reciprocal in both sides, x% / 100% = 165.1/384.7

=> x = ( 165.1/384.7) × 100

=> x = 42.91655835716 ~ 42.917 (round to the nearest thousandth). Therefore, 165.1 is 42.917% of 384.7.

does the line ever match up perfectly? can the lines ever have the same slope? can the lines ever have the same y-intercept? why or why not?

Answers

No, the lines cannot ever match up perfectly because there is always some sort of difference between them. The lines can have the same slope if they have the same change in y-values for a given change in x-values. The lines can also have the same y-intercept if they cross the y-axis at the same point.

No, there will never be a perfect alignment between the lines since there will always be a discrepancy of some kind. However, the lines can have the same slope and y-intercept. This is possible because the slope and y-intercept are determined by the equation of the line, and if two lines have the same equation, then they will have the same slope and y-intercept.

If the lines intersect the y-axis at the same location, they can also have the same y-intercept. This means that the two lines have the same value of b in the equation y = mx + b. This means that the two lines have the same slope and the same y-intercept.

the probability that a student at certain high school likes art is 35%. the probability that a student who likes art also likes science is 22%. find the probability that a student chosen at random likes science given that he or she likes art. round to the nearest tenth of a percent.

Answers

The probability that a student chosen at random likes science given that he or she likes art is 41.4%

In our case, we want to find P(Science|Art), which is the probability of a student liking science given that he or she likes art. Using Bayes' theorem, we have:

P(Science|Art) = P(Art|Science) x P(Science) / P(Art)

We know that P(Art) = 0.35 and P(Science|Art) = 0.22. To find P(Art|Science), we can use the formula:

P(Art|Science) = P(Science|Art) x P(Art) / P(Science)

We don't know P(Science) yet, but we can calculate it using the fact that:

P(Science) = P(Science|Art) x P(Art) + P(Science|Not Art) x P(Not Art)

where P(Not Art) is the probability that a student does not like art, which is 1 - P(Art) = 0.65. We are given that P(Science|Not Art) = 0.15, which is the probability that a student who does not like art likes science. Substituting these values, we get:

P(Science) = 0.22 x 0.35 + 0.15 x 0.65 = 0.1855

Now we can substitute all the values into Bayes' theorem:

P(Science|Art) = 0.22 x 0.35 / 0.1855 = 0.414 or 41.4%

The relationship between t, the number of tickets, and c, the total cost of tickets is: c = 55t

Relation between two variables, i.e, total cost and number of tickets:

The statistical relationship between two variables is called their correlation. The correlation can be positive, which means that the two variables move in the same direction, or negative, which means that when the value of one variable increases, the value of the other variable decreases.

Based n the Question:

Since there is no processing fee and the ticket price remains the same, we know that the fee will be proportional to the number of tickets purchased. The general form of the equation expressing the proportional relationship between the cost (c) and the number of tickets (t) is:

c = kt

where k is the constant of proportionality (the cost per ticket).

We can find k by using any of the data points given in the table. Using the first point, we have :

balloon?

Answers

Answer:

The volume of a sphere is given by the formula:

V = (4/3)πr^3

where r is the radius of the sphere.

Since the diameter of Casper's balloon is 6 inches, the radius is 3 inches. Therefore, the volume of Casper's balloon is:

V1 = (4/3)π(3 inches)^3 = 113.1 cubic inches (approx.)

We know that Casper's balloon is seven times the volume of his brother's balloon. Let's call the volume of his brother's balloon V2. We can set up an equation:

V1 = 7V2

Substituting the value of V1, we get:

113.1 cubic inches = 7V2

Dividing both sides by 7, we get:

V2 = 16.2 cubic inches (approx.)

Therefore, the approximate volume of Casper's brother's balloon is 16.2 cubic inches.

Answers

Siona bought 7 shirts and 3 pairs of shorts when she spent a total of $36.50. The problem can be solved using a system of equations.

Let's use a system of equations to solve this problem:

Let x be the number of shirts that Siona bought, and y be the number of pairs of shorts that she bought. Then we have:

Equation 1: x + y = 10 (Siona bought 10 outfits in total)

Equation 2: 3.50x + 4.00y = 36.50 (The total cost of the outfits is $36.50)

To solve for x and y, we can use substitution or elimination. Let's use substitution:

From Equation 1, we can solve for x in terms of y:

x = 10 - y

Substitute this expression for x into Equation 2:

3.50(10 - y) + 4.00y = 36.50

Simplify and solve for y:

35 - 3.50y + 4.00y = 36.50

0.50y = 1.50

y = 3

Now we can substitute y = 3 back into Equation 1 to solve for x:

x + 3 = 10

x = 7

Therefore, Siona bought 7 shirts and 3 pairs of shorts when she spent a total of $36.50.

Answers

Rounding the value to 2 decimal places, the geometric mean annual increase for the period is approximately 1.18.

Geometric mean annual increase for the period:

Let A be the initial value and B be the final value of the given data for the geometric mean annual increase for the period in the United States from 2000 to 2014.

A = 40,255,000 and B = 214,014,920.

Sara cut a 2 1/2 meter rope to hang a swing for her sister. How many centimeters is the rope

Answers

Length of the Sara's rope of 2 1/2 meter in centimeter is 25 centimeters.

To convert 2 1/2 meters to centimeters, we can use the conversion factor 1 meter = 100 centimeters. This means that:

2.5 meters = 2.5 x 100 centimeters

= 250 centimeters

Therefore, the length of the rope is 250 centimeters. It's important to understand and be able to convert between different units of measurement, as this is a common task in many fields such as science, engineering, and finance. For example, in science, it's important to be able to convert between different units of length, mass, and volume when making measurements or analyzing data. Similarly, in finance, it's common to convert between different currencies or units of time when dealing with investments or loans. Being able to make these conversions accurately is essential to avoid errors or misunderstandings. In this case, converting the length of the rope from meters to centimeters allows us to work with a more convenient unit for the task at hand, which is hanging a swing for Sara's sister.

suppose that a 17 ft ladder is sliding down a wall at a rate of 6 ft/sec. at what rate is the bottom of the ladder moving when the top is 8 ft from the ground?

Answers

The bottom of the ladder is moving at a rate of 1.333 ft/sec when the top is 8 ft from the ground

The bottom of the ladder is moving at a rate of 6 ft/sec when the top is 8 ft from the ground. This can be found by using the equation v = d/t, where v is the velocity, d is the distance, and t is the time. The distance is 8 feet (from the top of the ladder to the ground) and the time is 1/6 seconds (since the ladder is sliding down at a rate of 6 ft/sec). Therefore, the velocity of the bottom of the ladder when the top is 8 ft from the ground is 8/1/6 = 8/6 = 4/3 = 1.333 ft/sec.


To understand this concept more clearly, imagine a ball rolling along the ground. Its velocity is constant until it hits a slope and begins to move down the slope. At this point, its velocity increases as it moves further down the slope, and its velocity is higher when it is further down the slope.

This is the same concept as the ladder sliding down the wall; the bottom of the ladder is moving faster than the top, so the velocity of the bottom of the ladder increases as the top of the ladder gets closer to the ground.


In conclusion, the bottom of the ladder is moving at a rate of 1.333 ft/sec when the top is 8 ft from the ground. This can be found using the equation v = d/t, where v is the velocity, d is the distance, and t is the time. The distance is 8 feet and the time is 1/6 seconds since the ladder is sliding down at a rate of 6 ft/sec.

A student starts a walk at (−6, 10). If the student walks 4 miles north, south, east, or west, which of the following could be their location at the end of the walk?


HELP ME PLEASE!!!

Answers

Answer: Assuming the student walks along a rectangular grid and not diagonally, the possible locations the student could end up after walking 4 miles in any direction would be the points that are 4 units away from the starting point in a north, south, east, or west direction.

Using this information, we can determine that the possible locations the student could end up at are:

(-2, 10)

(-6, 14)

(-10, 10)

(-6, 6)

Therefore, the answer is:

All of the above locations are possible endpoints.

Step-by-step explanation:

If the student walks 4 miles north, south, east, or west,  the location at the end of the walk are respectively, (-6, 14). (-6, 6), (-2,10). (-10, 10).

What is a coordinate plane?

The Cartesian plane, named after the mathematician René Descartes (1596 - 1650), is a plane with a rectangular coordinate system that associates each point in the plane with a pair of numbers.

Given that,

A student starts a walk at (-6, 10)

If the student walks 4 miles north, south, east, or west,

The location at the end of the walk =

Plotting dotted diagram,

North --------- |-------------- South

                     |

                  West

Suppose, he goes to north  direction

Then, 4 will be added to y coordinate,

It can be written as,
