Answer:
The answer is 25Step-by-step explanation:
f(x) = 3x - 2
h(x) = - 2x² + 3x - 6
First to find f(7/3) substitute the value of x that's 7/3 into f (x)

For a local high school, 75% of the school population lives within 3 miles of the school and 20% of those who lived within 3 miles
walk to school.
If a student is selected at random, then what is the probability that the student lives within 3 miles and walks to school?
The probability that a student lives within 3 miles of the school is 75%, and the probability that a student who lives within 3 miles walks to school is 20%. We can find the probability that a student both lives within 3 miles and walks to school by multiplying these probabilities:
0.75 x 0.20 = 0.15
Therefore, the probability that a student lives within 3 miles and walks to school is 0.15 or 15%.

The graph of the function f is shown below Find one value of x for which f(x) =2 and find f(2)A- One value of X for which f(x)=2: B- f(2) =
To find the corresponding x where the function assumes a certain value, we draw a horizontal line on the desired function value. For f(x) = 2, we have:
The intercept between the horizontal line and our graph happens at (0, 2), therefore, we have:
\(f(x)=2\implies x=0\)To evaluate graphically a function, we check the corresponding value for the desired x value on the horizontal axis. For x = 2, we have:

Find the derivative of the function. z=(1−t)(4+t^2)^−1 Choose the correct answer below.
A. t^2−2t−4/(4+t^2)^2
B. t^2−2t−4/ (1−t)^2
C. −t^2+2t+4/(4+t^2)^2 D. −t^2+2t+4/(1−t)^2
The derivative of the function
\(z = (1 - t)(4 + t^2)^-1\) is \(dz/dt = -2t(1 - t)/(4 + t^2)^2 - 1/(4 + t^2)\).
Thus, the correct answer is C.
To determine the derivative of the function z = (1 - t)(4 + t²)^⁻¹, we can use the product rule and the chain rule.
Using the product rule, the derivative of z with respect to t is given by:
\(dz/dt = (1 - t)(d/dt)(4 + t^2)^-1 + (4 + t^2)^-1(d/dt)(1 - t)\)
Next, we apply the chain rule to differentiate the terms involving (4 + t²)^⁻¹ and (1 - t):
\((d/dt)(4 + t^2)^-1 = -(4 + t^2)^-2 * (d/dt)(4 + t^2) = -(4 + t^2)^-2 * 2t(d/dt)(1 - t) = -1\)
Substituting these derivatives back into the expression for dz/dt, we get:
\(dz/dt = (1 - t) * (-(4 + t^2)^-2 * 2t) + (4 + t^2)^-1 * (-1)\)
Simplifying this expression further, we have:
\(dz/dt = -2t(1 - t)/(4 + t^2)^2 - 1/(4 + t^2)\)
Therefore, the correct answer is option C: -t² + 2t + 4/(4 + t²)².

Nonperiodic waveforms. Jump to level 1 \[ v(t)=2 u(t-1)-3 u(t+5) \] At time \( t=-1, v(t)= \)
Therefore, the value of v(t) at time t = -1 is -3. The function v(t) is a nonperiodic waveform, which means that it does not repeat itself after a certain period of time.
The function is defined as follows:
v(t) = 2 u(t - 1) - 3 u(t + 5)
where u(t) is the unit step function. The unit step function is a function that is equal to 1 for all values of t greater than or equal to 0, and 0 for all values of t less than 0.
To find the value of v(t) at time t = -1, we simply substitute -1 into the function. This gives us:
v(-1) = 2 u(-1 - 1) - 3 u(-1 + 5)
The first unit step function evaluates to 0, because -2 < 0. The second unit step function evaluates to 1, because 4 > 0.
Therefore, the value of v(-1) is equal to:
v(-1) = 2 * 0 - 3 * 1 = -3
Therefore, the value of v(t) at time t = -1 is -3.

If repeated samples of size n are taken from a normal population with an unknown variance, then the statistic ______ follows the t distribution with n-1 degrees of freedom
In summary, when repeated samples of size n are taken from a normal population with an unknown variance, the statistic t follows the t-distribution with n-1 degrees of freedom.
If repeated samples of size n are taken from a normal population with an unknown variance, then the statistic t follows the t distribution with n-1 degrees of freedom. When a sample of size n is taken from a normal population with a known variance and mean, the sample mean follows a normal distribution with a mean of μ and a variance of σ2/n. This distribution is known as the sampling distribution of the mean.
However, when the variance is unknown, the sampling distribution of the mean can no longer be calculated using the normal distribution. In this scenario, the sample mean is calculated using a t-distribution instead of a standard normal distribution.The t-distribution is similar to the standard normal distribution. However, it is more spread out and flatter than the standard normal distribution. As a result, the t-distribution has thicker tails than the standard normal distribution, which makes it more suitable for analyzing small samples of data.

Which sequence of transformations create triangles that are similar instead of congruent?
Dilation and rotation will not produce a congruent triangle
What is rotation ?
The rotation of a point with regard to the origin is described by the rotation formula. To get the position of the point after rotation, apply the rotation formula. Rotation is a circular movement about the specific axis or point of rotation. In general, there are two common directions for rotation: clockwise and anti-clockwise or counter-clockwise.
Rotations, reflections and translations are known as rigid transformations; this means they do not change the size or shape of a figure, they simply move it. These rigid transformations preserve congruence.
Dilation, however, are not rigid transformations, since they change the size of a shape. Dilation would not change the shape, just the size; the angle measures would be the same, and the ratio of corresponding sides would be equal to the scale factor used in the dilation. This would give us a similar, but not congruent, figure.

The sum of 5 consecutive even numbers is 200
Answer:
36, 38, 40, 42, 44
Step-by-step explanation:
We can denote an even number as 2n (where n is a natural number).
Each consecutive even number will be 2 more than the previous number.
Let 1st number = 2n
⇒ 2nd number = 2n + 2
⇒ 3rd number = 2n + 4
⇒ 4th number = 2n + 6
⇒ 5th number = 2n + 8
Sum of all 5 numbers is 200.
⇒ 2n + 2n + 2 + 2n + 4 + 2n + 6 + 2n + 8 = 200
⇒ 10n + 20 = 200
⇒ 10n = 180
⇒ n = 18
If n = 18, then 2n = 36
Therefore, the numbers are 36, 38, 40, 42, 44

1. Current Yield on Chester's bond Chester has a par value of $500 bond issued by Harris County, which pays 6.2% yearly interest. When Chester bought it, the market rate of Harris County bonds was 101.760. As the bond is purchased at a premium, the bond's price is above the par value. It is trading above the face value of $500 per bond.Using the current market rate formula, C = (I/PV) + (FV/PV)n
Where ,C = Current YieldI = Yearly Interest PV = Current Market RateFV = Par Value ($500)n = Number of Years Then,
98.626 = (6.2/ PV) + (500 / PV)101.760
\((PV) = $498.70PV = $4.90\)
Therefore, the current market price of the bond is $4.90.Using the current yield formula, Current Yield = (Yearly Interest/Current Market Price) x 100Current
Yield \(= (6.2/4.90) x 100 = 126.53\)
Therefore, the current yield on Chester's bond is 126.53%.2. Investment with a greater return after six years After six years, the return on stocks and bonds investment will be calculated as: Stocks
Return = \(1,000(1 + 0.053)^6 = $1,385.94\)
Bonds Return = \(1,400(1 + 0.041)^6 = 1,734.69\)
Therefore, the return on bonds investment is $1,734.69, and the return on stocks investment is $1,385.94. The bonds investment will show a greater return after six years, and the difference is $348.75.3. Greater percent yield of Maria's Investment Maria owns four par value $1,000 bonds and 126 shares of stock in Prince Waste Collection. The bonds pay a yearly interest of 7.7%, and Maria bought them when the market value was 97.917.The cost of one stock = $19.33 and the yearly dividend per stock is 85 cents.
Maria's total investment in stocks = \(126\times$19.33 = $2,439.18\)
Maria's total investment in bonds = $1,000 x 4 = $4,000 When Maria bought bonds, the market value of the bond was \(979.17 ($1,000 x 0.97917).\)\(= (Yearly Interest / Purchase Price) \times 100= (7.7 / 979.17) \times 100 = 0.786%\)
The stock's annual yield\(= (Dividend / Purchase Price) \times100= (0.85 / 19.33) \times 100 = 4.4%\)
Therefore, the percent yield on stocks is greater, and the difference is 3.61%.

What is the usefulness of Cluster Analysis? What is Hierarchical
Clustering? Give examples.
Cluster analysis is a valuable tool in data analysis that helps identify hidden patterns and group similar objects or data points.
It is useful in various fields, such as market research, image analysis, customer segmentation, and anomaly detection. By clustering data, we can gain insights, make predictions, and improve decision-making. Hierarchical clustering is a specific approach to cluster analysis. It organizes data points into a hierarchy of clusters, where each cluster can contain subclusters. This method allows for a hierarchical structure that captures different levels of similarity or dissimilarity between data points.
For example, in customer segmentation, hierarchical clustering can group customers based on similar attributes like demographics, purchase history, and behavior. In image analysis, it can be used to segment images into meaningful regions or objects based on their visual characteristics. Hierarchical clustering offers a flexible and interpretable way to analyze complex datasets and discover underlying structures.
