From Bayes' Theorem, an events related to involved in a hit and run accident at night. The required probability that the blue cab involved in accident rather than green as well as witness also identified it as blue cab is equals to the 0.41 or 41% .
Bayes' Theorem states that the conditional probability of an event, is based on the occurrence of another event, is equal to the likelihood of the second event the first event multiplied by the probability of the first event. According to scenario, it is found that a cab was involved in a hit and run accident at night. Number of cab companies operates in city = 2 ( blue and green)
Probability that green cab involved in accident, P(G) = 85% = 0.85
Probability that blue cab involved in accident, P( B) = 15% = 0.15
Now, the cab which is identified by witness was a blue cab and after identification court also tested the witness's credibility. Here, probability that witness is correct to identification a blue cab = P(W/B) = 0.80
Probability that witness is wrong to identify the blue cab = P(W/G)
= 0.20
Using the Baye's theorem, Probability that accident was caused by blue cab provided witness identifies is, [tex]P( B/W) = \frac{ P(B ∩W )}{ P( W)} = \frac{ P( B) P( W/B)}{ P( W)} \\ [/tex]
Total Probability, P(W) = P(B)P(W/B) + P(G)P(W/G)
= 0.15 × 0.8 + 0.85 × 0.2 = 1.2 + 1.7 = 2.9
P(B/W) = (0.15 × 0.8)/2.9
= 1.2/2.9 = 0.41 = 41%
Hence, required probability value is 41%.

A company finds that on average, they use 43 minutes for each meeting.
An employee sketches a graph to show the total amount of time in minutes, T, used for m meetings. The graph shows the value of T for 1 to 5 meetings.
If the employee counts by 10's, what should be the largest value on the T-axis of his or her graph so that the scale is the most appropriate for the given information?
The largest value on the T-axis of his or her graph so that the scale is the most appropriate for the given information is 220.
How to plot a graph?Plotting a graph involves visually representing numerical data using a coordinate system. The following steps can be used as a general guide to plot a graph:
1. Determine the type of graph needed: There are different types of graphs such as line graphs, bar graphs, pie charts, etc. The type of graph you choose will depend on the nature of the data being represented.
2. Choose a scale: This involves selecting appropriate values for the x and y-axes of the graph. The scale should allow the data to be displayed clearly, and evenly spaced marks should be used to represent values.
3. Plot the data: Mark the points or bars representing the data on the graph, using the selected scale.
4. Label the axes: Label both the x and y-axes with a description of what each represents, and include units of measurement where applicable.
5. Title the graph: Give the graph a descriptive title that indicates the purpose of the graph.
6. Add any necessary details: Additional details such as a legend, data source, or notes can be included to provide further information about the data or the graph.
7. Review and revise: Check the graph to ensure that it accurately represents the data and is visually clear. Make any necessary revisions to improve the graph's effectiveness.
To determine the largest value on the T-axis of the graph, we need to first find the maximum possible value of T for the given information.
Since the average time used for each meeting is 43 minutes, the total time used for m meetings can be expressed as T = 43m.
To find the maximum value of T for 5 meetings, we substitute m = 5 into the equation:
T = 43(5) = 215
Therefore, the largest value on the T-axis should be slightly larger than 215 to provide a little bit of extra space on the graph.
If the employee counts by 10's, a good choice for the largest value on the T-axis would be 220. This would allow for the values of T for 1 to 5 meetings to be evenly spaced on the graph, with each mark on the T-axis representing 10 minutes of time.

a 4,439. 92
b 2,219. 96
c 2,114. 96
d 1324. 48
If the house value of $89,548 and two points, attorney's fees $324, title fees $105, then closing cost is option (b) $2,219.96
Closing costs are fees associated with the purchase or refinance of a property that are paid at the closing of the transaction.
To calculate the closing cost, we need to add up all the fees associated with the purchase of the house.
First, we need to calculate the cost of the points. Two points on a house value of $89,548 would be
2 x $89,548 x 0.01 = $1,790.96
Next, we need to add the attorney's fees and title fees
$1,790.96 + $324 + $105 = $2,219.96
Therefore, the correct option is (b) $2,219.96

A clinical trial is performed to test a new drug designed to lower blood sodium levels. One hundred fifty participants are randomly assigned to take the new drug, and 150 participants are randomly assigned to take a placebo. After 6 months of treatment, blood sodium levels are measured and compared to the starting levels. For those who took the new drug, the blood sodium levels had a mean reduction of 27 points with a standard deviation of 5.2, while for those who took the placebo, the blood sodium levels showed a mean reduction of 22 points with a standard deviation of 3.9. Assuming the standard deviations are true for the entire population, calculate 90% confidence intervals and evaluate whether there is evidence the new drug is working.
A: The interval for the new drug is from 26.168 to 27.832 points. The interval for the placebo is from 21.376 to 22.624 points. Since the interval for the new drug lies above the interval for the placebo, there is evidence that the drug is working.

3. In raising a 7000 N motorcycle with a pulley system, the workers note that for every 3 m of rope pulled down- ward, the piano rises 0. 3 m. Show that 700 N is required to lift the motorcycle
If workers note that for every "3 m" of rope pulled down-ward, the piano rises 0.3 m, then we have shown that 700 N is required force to lift the motorcycle.
The term "Mechanical advantage" (MA) is defined as ratio of "output-force" to "input-force" in a machine.
In this case, the output force is the weight of the motorcycle (7000 N) and the input force is the force applied to pull the rope downward.
We use the formula for mechanical advantage in a pulley system, which is given by:
⇒ MA = (distance moved by the effort) / (distance moved by the load),
In this case, the distance moved by the effort is 3 m, and
The distance moved by the load is 0.3 m,
Substituting the values,
We get,
⇒ MA = 3/0.3,
⇒ MA = 10,
So, mechanical advantage of "pulley-system" is 10.
Now, we use mechanical advantage to calculate the required force to lift the motorcycle.
Since mechanical advantage is defined as the ratio of output force to input force, we can rearrange the formula as:
⇒ Input force = (Output force)/(Mechanical advantage),
Substituting values for "output-force" as 7000 N and "mechanical-advantage" as 10,
We get,
⇒ Input force = 7000/10,
⇒ 700 N,
Therefore, the required force to lift motorcycle is 700 N.

if cov(z,x) ≠ 0, then z and x are correlated. a. true b. false
True. If the covariance between two variables (z and x in this case) is not equal to zero, then it indicates that there is some degree of linear relationship or association between the two variables. Therefore, they are said to be correlated.
A measure of the link between two random variables and how much they fluctuate together is called covariance. Alternately, we may say that it establishes the relationship between the two variables' changes, i.e., that a change in one variable is equivalent to a change in the other. A function has the ability to preserve its shape even after a linear transformation of the input variables. The units of covariance are determined by multiplying the units of the two variables.

The volume of a rectangular prism is calculated by multiplying its length, width, and height, while its surface area is calculated by adding up the areas of all six faces.
volume of a rectangular prism:
volume = length * width * height
We know the volume is 219.375 in³, the height is 6.5 in, and the length is 11.25 in. Let's substitute these values into the formula and solve for the width:
219.375 = 11.25 * width * 6.5
Dividing both sides by (11.25 * 6.5), we get:
width = 219.375 / (11.25 * 6.5) ≈ 3
Therefore, the width of the box is approximately 3 inches.

Maxine graphs the function m(x) which has a vertex of (-3,4) and passes through the point (-1,-8). Ricardo graphs p(x) = (x+3)² +4
Maxine thinks that both functions have the same axis of symmetry equation. Do you agree or disagree?
Therefore, both functions have the same axis of symmetry equation, which is x = -3.
What is function?In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. Functions are one of the central objects of study in mathematics and have many applications in various fields such as physics, economics, engineering, and computer science. A function is typically represented using a mathematical expression or equation, and it can be analyzed and manipulated using a variety of mathematical techniques.
Here,
Both functions have a vertex of (-3,4), which means that the axis of symmetry must be a vertical line passing through x = -3.
For the function p(x) = (x+3)² +4, the axis of symmetry is indeed x = -3.
For the function m(x), since it has a vertex of (-3,4), the equation of the axis of symmetry is x = -3.

highway accidents: dui the u.s. department of transportation, national highway traffic safety administration, reported that 77% of all fatally injured automobile drivers were intoxicated. a random sample of 27 records of automobile driver fatalities in kit carson county, colorado, showed that section 8.3 testing a proportion p 479 15 involved an intoxicated driver. do these data indicate that the population proportion of driver fatalities related to alcohol is less than 77% in kit carson county? use a 5 0.01.
The highway accident evidence to reject the null hypothesis that the population proportion is equal to 77%.
No, these data do not indicate that the population proportion of driver fatalities related to alcohol is less than 77% in Kit Carson County.
The sample proportion of 15 out of 27 is 56.25%, which is not significantly different from the population proportion of 77%.
The p value for this test is 0.788, which is greater than the alpha level of 0.01.
The p value of this test indicates that the sample proportion of 15 out of 27 (56.25%) is not significantly different from the population proportion of 77%.
This means that there is not enough evidence to reject the null hypothesis that the population proportion is equal to 77%.
The p value of 0.788 is greater than the alpha level of 0.01, meaning that the results of this test are not statistically significant enough to support the alternative hypothesis that the population proportion is less than 77%.

To help determine what types of clubs to offer at harding middle school the principal surveyed fifty 8th grades. Does the sampl fairly represent the population ? explain
To determine if the sample fairly represents the population, we need to consider whether the sample is representative and whether there is any bias present in the sampling process.
If the principal surveyed fifty 8th graders in a way that ensures that each 8th grader in the population has an equal chance of being selected, then the sample can be considered representative. This means that the sample accurately reflects the characteristics of the population, and any conclusions drawn from the sample can be applied to the population.
However, if the sampling process was biased in some way, the sample may not be representative of the population. For example, if the principal only surveyed 8th graders in one class or in one particular group, the sample may not be representative of the entire 8th-grade population at Harding Middle School. In this case, any conclusions drawn from the sample may not accurately reflect the entire population.
Therefore, the key factor in determining whether the sample fairly represents the population is the sampling method used. If the sampling method is random and unbiased, then the sample can be considered representative of the population.
