Answer:
y = −1/3x+17/3
Step-by-step explanation:
The line segment has slope -1/3. This means that any line perpendicular to it will have a slope of 3 (negative reciprocal)
Any line that bisects the line segment will pass through its midpoint. The midpoint is (5,4)
Midpoint formula: \(( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )\)
So perpendicular bisector of this line is simply a line with slope −1/3 that passes through point (5, 4)
y - 4 = -1/3 (x-5)=
y = −1/3x+17/3
g a runner wants to run 10.1 km . her running pace is 6.8 mi/hr . how many minutes must she run?
I runner is running at the speed of 6.8 miles/hr and he wants to run 10.1 km then he runner must run for 9.3 minutes.
To calculate this, we first need to convert the given speed from miles per hour to kilometers per hour. 6.8 mi/hr is equal to 10.9 km/hr.
Then, we need to divide the total distance (10.1 km) by the speed (10.9 km/hr) to get the total time it will take for the runner to complete the 10.1 km run.
10.1 km/10.9 km/hr = 0.922 hr = 9.3 minutes.
Therefore, the runner must run for 9.3 minutes in order to complete the 10.1 km run.

A component of a computer has an active life, measured in discrete units, that is a random variable T, where Pr{T = k} == a,, for k = 1, 2.... . Suppose one starts with a fresh component, and each component is replaced by a new component upon failure. Let X,, be the age of the component in service at time n. Then {Xn} is a success runs Markov chain. (a) Specify the probabilities "pi" and "qi". (b) A "planned replacement" policy calls for replacing the component upon its failure or upon its reaching age N, whichever occurs first. Specify the success runs probabilities "pi" and "qi" under the planned replacement policy.
(a) We have:
pi = a, for i = 0, 1, 2, ...
qi = 1 - a, for i = 0, 1, 2, ...
(b) We have:
pi = a, for i = 0, 1, 2, ..., N-1
pi = 0, for i = N
qi = 1 - a, for i = 0, 1, 2, ..., N-1
qi = 0, for i = N
(a) To specify the probabilities "pi" and "qi" for the success runs Markov chain, we need to define the transition probabilities.
Let's define "pi" as the probability of a component lasting exactly "i" units of time before failing, and "qi" as the probability of a component failing at or before "i" units of time.
For the success runs Markov chain, the transition probabilities are as follows:
- The probability of moving from state "i" to state "i + 1" is "a" since it represents the probability of the component surviving one additional unit of time.
- The probability of moving from state "i" to state "0" (failure) is "1 - a" since it represents the probability of the component failing.
Therefore, we have:
pi = a, for i = 0, 1, 2, ...
qi = 1 - a, for i = 0, 1, 2, ...
(b) Under the planned replacement policy, the component is replaced upon its failure or upon reaching age N, whichever occurs first. This policy introduces an additional state to the Markov chain, which is the state of replacement (state N).
The updated transition probabilities for the success runs Markov chain under the planned replacement policy are as follows:
- The probability of moving from state "i" to state "i + 1" (where i < N) remains "a" since the component continues to function.
- The probability of moving from state "i" to state "N" (replacement) is "1 - a" since the component fails before reaching age N.
- The probability of moving from state "N" to state "0" (failure) is 1 since the replacement occurs at age N, and the new component starts at age 0.
Therefore, we have:
pi = a, for i = 0, 1, 2, ..., N-1
pi = 0, for i = N
qi = 1 - a, for i = 0, 1, 2, ..., N-1
qi = 0, for i = N

Aj rums 400 yards every week. Aj walks 90 more yards than he runs. Which equation can be used to find x, the number of yards that Aj walks and runs each week
The equation that can be used to find x, the number of yards that Aj walks and runs each week is 2x = 400 + 90.
Let's assume that Aj runs x yards each week. Then, the number of yards that Aj walks each week would be (x + 90) yards, since he walks 90 more yards than he runs.
The total distance that Aj covers each week would be the sum of the distance that he runs and the distance that he walks, which is given as 400 yards.
So, we can write an equation as:
Distance covered by Aj = Distance that he runs + Distance that he walks
or,
400 = x + (x + 90)Simplifying this equation gives:
2x = 400 + 90Therefore, the equation that can be used to find x, the number of yards that Aj walks and runs each week is 2x = 400 + 90.

The names of 11 boys and 9 girls from your class are put into a hat. What is the probability that the first two names chosen will both be girls?
Show work please and Thanks
Answer:
18/95
Step-by-step explanation:
There are a total of 20 names, 9 of which are girl names.
The probability that the first name is a girl name is 9/20.
Since there's one less girl name in the hat, there are now a total of 19 names, 8 of which are girl names. So the probability that the second name is a girl name is 8/19.
The total probability is (9/20) (8/19) = 18/95.

When training a classifier, the training set is used to learn the conditional probabilities.
The training set is used to learn the conditional probabilities because the training set is used to train the classifier on the patterns and features in the data, which in turn helps the classifier to learn the conditional probabilities of the different classes in the data.
The hold-out set and test set are used to evaluate the performance of the classifier and ensure that it is not overfitting to the training set.
By evaluating the classifier on data that it has not seen before, we can get a more accurate estimate of its true performance and the probability of correctly classifying new data.

suppose that wedding costs in the caribbean are normally distributed with a mean of $9000 and a standard deviation of $995. estimate the percentage of caribbean weddings that cost
Inferring from the provided mean and standard deviation that 15.62 percent of Caribbean weddings have a budget of less than $8,000 is our best guess.
To solve this problemWe can use the properties of the normal distribution.
Given:
Mean (μ) = $9000
Standard deviation (σ) = $995
Let's imagine we want to calculate the proportion of Caribbean weddings that are less expensive than X dollars.
We must use the following formula to determine X's z-score in order to determine this percentage:
z = (X - μ) / σ
Once we know the z-score, we may use a statistical calculator or the conventional normal distribution table to determine the corresponding cumulative probability.
Let's estimate the proportion of Caribbean weddings that cost less than $8000, for illustration.
z = ($8000 - $9000) / $995
z = -1.005
We may determine that the cumulative probability corresponding to z = -1.005 is roughly 0.1562 using the usual normal distribution table.
To convert this into a percentage, we multiply by 100:
Percentage = 0.1562 * 100
Percentage ≈ 15.62%
Therefore, Inferring from the provided mean and standard deviation that 15.62 percent of Caribbean weddings have a budget of less than $8,000 is our best guess.

How much area does the playground cover?
Answer:
a.) Total distance Julie cover = 128 feet
b.) Total area , the playground cover = 256 ft²
Step-by-step explanation:
P. S : The exact question is -
As given,
Length of 1 side = 16 feet
As , we have
4 sides of same length
⇒ Total length of playground = 16 + 16 + 16 + 16 = 16(4) = 64 feet
a.)
As given Julie does 2 lap of the playground
⇒ Total distance Julie cover = 64 + 64 = 128 feet
b.)
As the playground has equal side, so it must be of square shape
And, we know
Area of square = (Length of one side)²
= ( 16 )² = 256 ft²
∴ we get
Total area , the playground cover = 256 ft²

please help.
To find the values of x, y, and z in the equation (3 x 5)^4 x (2 x 3)^5 x (2 x 5)^7 = 2x x 3y x 5z, we need to examine the prime factorization of each side of the equation and equate the exponents of the prime factors.
Let's break down both sides of the equation and examine the prime factorization of each term.
On the left side:
(3 x 5)^4 = 3^4 x 5^4 = 81 x 625
(2 x 3)^5 = 2^5 x 3^5 = 32 x 243
(2 x 5)^7 = 2^7 x 5^7 = 128 x 78125
Combining the terms on the left side, we have:
81 x 625 x 32 x 243 x 128 x 78125
On the right side:
2x x 3y x 5z
By comparing the exponents of the prime factors on both sides, we can set up the following equations:
For the prime factor 2:
4 = 1x
The only value of x that satisfies this equation is x = 4.
For the prime factor 3:
5 = y
The value of y is y = 5.
For the prime factor 5:
7 = z
The value of z is z = 7.
Therefore, the correct values for x, y, and z in the equation are x = 4, y = 5, and z = 7.
