what is the weighted mean, mean, and median overall rate of return on this investment portfolio?

The ratio of the horizontal change to the vertical change of a line would not be used to describe a slope. Thus the correct option is option C.

The slope of a line is defined as the ratio of the vertical change (rise) to the horizontal change (run) of a line.

Slope=Vertical Change/Horizontal Change

This is also represented as the "ratio of rise to run of a line".

Slope=Rise/Run

In the given question, however, option C states that the "ratio of the horizontal change to the vertical change of a line".

Horizontal Change/ Vertical Change= 1/slope

This is an incorrect statement since the ratio of the horizontal change to the vertical change of a line is the reciprocal of the correct ratio.

The graph of f(x)=√x could be transformed to form the graph of g(x)=√x+4 c) vertical shift of 4 units up.

When functions are changed, the graph's representational curve "moves to the left/right/up/down," "expands or compresses," or "reflects."

A vertical movement of 4 units up is the explanation for how the graph of f(x)=x might be changed to become the graph of g(x)=x+4.

Translations, reflections, and dilations are the three different forms of transformations. A function can be transformed in one of two ways: vertically (affecting the y-values) or horizontally (affects the x-values).

Step-by-step explanation:

While there are no examples available, there is the room to understand each angle type you listed, vertical angles are angles that are opposite from each other, and they are congruent (they have the same angle in degrees) now, imagine that for vertical angles, they are in an X top and bottom are equal, and the two sides are equal. For a straight angle, that is usually two angles that are right angles (90 degrees) back to back, meaning when you add 90 and 90 degrees together, you get a straight line or a 180 degree angle. An example of an acute angle is any angle less than 90 degrees, that is a real number, so imagine 25, 40, and 60 as all acute angles.

Step-by-step explanation:

The cost of linoleum needed to cover the dining room is P296,450.00 for the region.

The given problem is related to the "region" and "cover". We have to find the cost of linoleum needed to cover the dining room.

Let's solve this problem step by step:

Given, the region bounded by the y-axis, z-axis and the lines y - 25 - 52 and y - z + 3.

We know that the formula of area bounded by the curve is given by \(`∫ f(y) - g(y) dy`\) where f(y) is the upper curve and g(y) is the lower curve. In this problem, the lower curve is z = 0. The upper curve y - 25 - 52 = y - 77 => y = 77 is the upper curve.

Therefore, the area bounded by the curve is given by: \(∫0^77 y-77dy= [(77)^2/2] - [(0)^2/2] = 2964.5 m²\)The linoleum costs P100.00/m², therefore the cost of linoleum needed to cover the dining room is:

Cost = 100 x 2964.5= P296,450.00

Therefore, the cost of linoleum needed to cover the dining room is P296,450.00.

The number of feet Jacob has traveled since he started walking toward Elizabeth is 2.5t .

Let the distance between Jacob and Elizabeth is 210 feet

Distance = speed x time

Jacob is walking at the constant speed of 2.5 feet per second

and Elizabeth is walking at a constant speed of 4.5 feet per second

Let the distance traveled by jacob be x and distance traveled by Elizabeth be (210 - x)

Let t be time passed when they both started walking towards each other

So the time taken by Jacob to cover x amount of distance is t

so by formula Distance = speed x time

x = 2.5 x t

So number of feet jacob has traveled since he started walking toward elizabeth is 2.5t.

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in common usage.

In a left-tailed test with α = .01, the β risk (Type II error) and power are calculated for a sample of 27 gallons of flat white interior latex paint, with a claimed coverage of 430 square feet per gallon and a known standard deviation of 18. Assuming the true mean is 410 square feet per gallon, the β risk is approximately 0.268 and the power is approximately 0.732.

To calculate the β risk and power, we need to determine the critical value for the test statistic and compare it to the true mean. In this case, it is a left-tailed test with α = .01, which means we reject the null hypothesis if the sample mean is significantly lower than the claimed mean.

First, we find the critical value corresponding to α = .01. Since the sample size is large (n = 27), we can use a Z-test. The critical value is found using the standard normal distribution table, giving us a critical Z-value of -2.33 (approximately).

Next, we calculate the standard error of the mean, which is the standard deviation divided by the square root of the sample size. In this case, the standard error is 18 / √27 ≈ 3.46.

Then, we calculate the test statistic, which is the difference between the sample mean and the claimed mean, divided by the standard error. The test statistic is (410 - 430) / 3.46 ≈ -5.78.

Using the critical value and the test statistic, we find that the test statistic is less than the critical value, indicating that we reject the null hypothesis. This means that there is evidence to suggest that the true mean coverage is lower than the claimed mean.

To calculate the β risk, we need to find the Z-value corresponding to the difference between the true mean (410) and the claimed mean (430), divided by the standard error. The Z-value is (410 - 430) / 3.46 ≈ -5.78. Looking up this Z-value in the standard normal distribution table, we find the corresponding probability is approximately 0.000, which is the β risk.

Finally, the power is calculated as 1 minus the β risk, giving us a power of approximately 1 - 0.000 = 0.999 or 99.9%. This means that there is a high probability (99.9%) of correctly rejecting the null hypothesis when the true mean is 410 square feet per gallon.

In conclusion, at α = .01 in a left-tailed test, assuming the true mean is 410 square feet per gallon, the β risk is approximately 0.268 (26.8%) and the power is approximately 0.732 (73.2%). These values indicate that there is a moderate risk of committing a Type II error (failing to reject the null hypothesis when it is false) and a relatively high power to correctly detect a significant difference between the claimed and true means.

Answer:    P(King AND King) = 1/221

Step-by-step explanation:

There are 4 Kings in a deck of 52 cards total

Probability of getting a King first time:

P(King) = 4/52                        > 4 Kings out of 52 total cards

P(King) = 1/13                          >reduced fraction by dividing top and

                                                bottom by 4

Probability of getting another king:

P(King) = 3/51                      > You took out a king so there are 3 left and 1

                                                 less to the total making 51

P(king) = 1/17                        >Reduced by dividing top and bottom by 3

Probability of getting king and then king again.  The second king is dependent on you getting a king the first time.  Because it is dependent, you multiply the 2 probabilities

P(King AND King) = (1/13)(1/17)

P(King AND King) = 1/221

The probability of a person being randomly choosing having waiting time greater than 4.25 is 0.2917 or 29.17%.

To answer this question we need to know about-

Probability is the measure of the likelihood of an event to happen. The probability value ranges between 0 and 1.

When the probability value is 0, it means that the event is impossible to happen.

When the probability value is 1, it means that the event is certain to happen.

Uniform distribution is when the values of a probability distribution are spread uniformly across the interval, it is called a Uniform distribution

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 6 minutes.

The probability that a randomly selected passenger has a waiting time greater than 4.25 minutes is found as follows:

Let X = Waiting time of a randomly selected passenger P(X > 4.25) = ?

Now we have to use the uniform distribution formula to find the probability:

P(C< X >D)=C-D/B-A

where C = lower value of the selected interval

           D= upper value of the selected interval

           B= highest value of the selected interval

           A= lowest value of the selected interval

putting above values in the formula -

P(X > 4.25) = 6 - 4.25/6-0= 0.2917

Hence the probability that a randomly selected passenger has a waiting time greater than 4.25 minutes is 0.2917.
