Suppose X,Y and Z are three different random variables. Let X obey a Bernoulli Distribution. The probability distribution function is. c is a constant here.
Let Y obey the Standard Normal (Gaussian) Distribution, which can be written as Y N(0,1). X and Y are independent. Meanwhile, let Z = XY.
Calculate the covariance of Y and Z (Cov(Y, Z)) and determine whether values of c would affect the correlation.
Answers
The value of c does not affect the covariance of Y and Z.
How did we arrive at this assertion?The covariance of Y and Z can be calculated as Cov(Y, Z) = E[YZ] - E[Y]E[Z]. Since X is Bernoulli with parameter p and E[X] = p, we have E[Z] = pE[Y]. Hence,
Cov(Y, Z) = E[YZ] - E[Y]E[Z]
= E[YXY] - pE[Y]^2
= pE[Y^2 X] - pE[Y]^2
= p(E[Y^2]E[X] + Var[Y]p) - pE[Y]^2
= p(1 * p + 1 * p^2) - p^2
= p - p^2
It can be seen that the value of c does not affect the covariance of Y and Z.

Data can be described by a single number using summary statistics. Summary statistics provide a concise representation of the main characteristics of a dataset.
Commonly used summary statistics include measures such as the mean, median, mode, range, variance, and standard deviation.
These single numbers provide insights into different aspects of the data, such as the central tendency, variability, or distribution.
Tables and graphs are effective tools for representing data and answering questions because they provide a visual representation that helps to organize and understand the information.
Tables present data in a structured format, typically using rows and columns, which allows for easy comparison and analysis.
They can display raw data, summary statistics, or both.
Graphs, on the other hand, use visual elements to represent data in a more intuitive and visual manner.
Different types of graphs can be used depending on the nature of the data and the question at hand.
For example, bar graphs can be used to compare categories or discrete data, line graphs can show trends over time, and scatter plots can display the relationship between two variables.
Tables and graphs help to answer questions about data by providing a clear and organized presentation.
They allow us to observe patterns, trends, and relationships, making it easier to draw conclusions and make informed decisions.

In the diagram below, line segment AB has endpoints at A(-2,-6) and B( 3,-1) .Draw A'B' the image of AB after a counterclockwise rotation of 90° about the origin. Give the coordinates of its endpoints below. Is A'B' congruent to AB? Explain.
Answers
By definition, you know that when a point is rotated 90 degrees counterclockwise about the origin, point A (x, y) becomes A'(- y, x).
Then, if you rotate 90 degrees counterclockwise about the origin the points A and B you get:
\(\begin{gathered} A(-2,6)\rightarrow A^{\prime}(-6,-2) \\ B(3,-1)\rightarrow B^{\prime}(-(-1),3)=B^{\prime}(1,3) \end{gathered}\)Now graphing points A and B and their respective rotations you have
Now, to know if the segments AB and A'B 'are congruent, you can find a measure of each one of them using the distance formula, which is
\(d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}\)So, for the measure of segments AB you have
\(\begin{gathered} (x_1,y_1)=(-2,-6) \\ (x_2,y_2)=(3,-1) \\ d_{AB}=\sqrt[]{(3-(-2))^2+(-1-(-6))^2} \\ d_{AB}=\sqrt[]{(3+2)^2+(-1+6)^2} \\ d_{AB}=\sqrt[]{(5)^2+(5)^2} \\ d_{AB}=\sqrt[]{25+25} \\ d_{AB}=\sqrt[]{50} \\ d_{AB}=7.07 \end{gathered}\)For the measure of segments A'B' you have
\(\begin{gathered} (x_1,y_1)=(-6,-2) \\ (x_2,y_2)=(1,3) \\ d_{A^{\prime}B^{\prime}}=\sqrt[]{(1-(-6))^2+(3-(-2))^2} \\ d_{A^{\prime}B^{\prime}}=\sqrt[]{(1+6)^2+(3+2)^2} \\ d_{A^{\prime}B^{\prime}}=\sqrt[]{(7)^2+(5)^2} \\ d_{A^{\prime}B^{\prime}}=\sqrt[]{49+25} \\ d_{A^{\prime}B^{\prime}}=\sqrt[]{74} \\ d_{A^{\prime}B^{\prime}}=8.6 \end{gathered}\)Then, as you can see, the segments AB and A'B'do not have the same measure and therefore are not congruent.

Answers
The z-scores for the given data values 520, 640, 500, 470, and 320 are:
0.2, 1.4. 0, -0.3, -1.8
To calculate the z-scores for each data value, we can use the formula:
z = (x - μ) / σ
where:
x is the data value
μ is the population mean (in this case, 500)
σ is the population standard deviation (in this case, 100)
Let's calculate the z-scores for each data value:
For x = 520:
z = (520 - 500) / 100 = 0.2
For x = 640:
z = (640 - 500) / 100 = 1.4
For x = 500:
z = (500 - 500) / 100 = 0
For x = 470:
z = (470 - 500) / 100 = -0.3
For x = 320:
z = (320 - 500) / 100 = -1.8
Therefore, the z-scores for the given data values are:
z-score for 520: 0.2
z-score for 640: 1.4
z-score for 500: 0
z-score for 470: -0.3

The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 23.5 for a sample of size 775 and standard deviation 12.2. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 95% confidence level). Enter your answer as a tri-linear inequality accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).
Answers
The 95% confidence interval for the effectiveness of the blood-pressure drug is given as follows:
\(22.6 < \mu < 24.4\)
How to obtain the confidence interval?The mean, the standard deviation and the sample size for this problem, which are the three parameters, are given as follows:
\(\overline{x} = 23.5, \sigma = 12.2, n = 775\)
Looking at the z-table, the critical value for a 95% confidence interval is given as follows:
z = 1.96.
The lower bound of the interval is then given as follows:
\(23.5 - 1.96 \times \frac{12.2}{\sqrt{775}} = 22.6\)
The upper bound of the interval is then given as follows:
\(23.5 + 1.96 \times \frac{12.2}{\sqrt{775}} = 24.4\)

How to Write 3 1/2 cups as a multiplication expression using the unit, 1 cup, as a factor.To express 3 1/2 cups as a multiplication expression using the unit "1 cup" as a factor, you can write it as:
3 1/2 cups = (3 + 1/2) cups = 3 cups + 1/2 cup
Since there are 1 cup in each term, we can rewrite it as:
3 cups + (1/2) cup
Now, we can express each term as a multiplication expression:
3 cups = 3 * 1 cup = 3
(1/2) cup = (1/2) * 1 cup = 1/2
Putting it all together, the multiplication expression is:
3 * 1 cup + (1/2) * 1 cup = 3 + 1/2

A train running between two stations 50 Km apart arrives on time if it travels at an
average speed of 60 km/h. How late will it be if travels at an average speed of 50 Km/h?
Answers
If the train travels at an average speed of 50 Km/h, it would be late by 10 minutes.
How late will the train be if it travels at an average speed of 50 Km/h?Speed is simply referred to as distance traveled per unit time.
It is expressed as:
Speed = distance / time
Given that the train running between two stations 50 Km apart arrives on time if it travels at an average speed of 60 km/h.
The time taken by the train to travel 50 km at an average speed of 60 km/h can be calculated using the formula:
Speed = distance / time
time = distance / speed
time = 50 km / 60 km/h
time = 5/6 hour
Next, if the train travels at an average speed of 50 km/h, the time taken to cover the same distance of 50 km would be:
Speed = distance / time
time = distance / speed
time = 50 km / 50 km/h
time = 1 hour
Now, the difference in time between the two scenarios would be:
time difference = 1 hour - 5/6 hour
time = 1/6 hour
Convert to minutes
time = 1/6 × 60
time = 10 minutes
Therefore, the train would be late by 10 minutes.

Water is pumped out of the conical tank with vertex down and radius 8 ft and height 20 ft. If the volume is decreasing at a rate of 4 ft^3sec :
how fast is the depth of the water decreasing when the water is 9 ft deep? (Note: Don't approximate the answer and state its exact value in terms of π.)
Answers
It took approximately 151 seconds to decrease 9 ft water in conical tank.
The volume of a conical tank with vertex down and radius 8 ft and height 20 ft is V = (1/3)πr²h
When the water is 9 ft deep
= (1/3) ×3.14×(8)²×(9)
= 602.88 ft³
We know that the rate of change of volume is 4 ft³/sec. So, the rate of change of depth can be calculated as follows:
Rate of change of depth (dh/dt) = Volume of tank/4 ft³ per sec
= 602.88/4
