A frequency polygon displays class frequencies while an ogive displays cumulative frequencies.

Is an ogive and a frequency polygon the same?A frequency polygon is a line graph while an orgive is a histogram . A frequency polygon displays class frequencies while an orgive displays cumulative frequencies there is no difference between a frequency polygon and ogive.The area under the frequency polygon is the same as the area under the histogram and is, therefore, equal to the frequency values that would be displayed in a distribution table. The frequency polygon also shows the shape of the distribution of the data, and in this case, it resembles a bell curve.The frequency polygon is a curve that is drawn on the x-axis and the y-axis. The x-axis represents the values in the dataset, while the y-axis shows the number of occurrences of each distinct category.An Ogive Chart is a curve of the cumulative frequency distribution or cumulative relative frequency distribution. For drawing such a curve, the frequencies must be expressed as a percentage of the total frequency.

Assume that when adults with smartphones are randomly selected, 49% use them in meetings or classes. If 15 adult smartphone users are randomly selected find the probability that fewer than 3 of them use their smartphones in meetings or classes.

Answers

We can calculate the probability of having less than 3 smartphone users among 15 users by using the binomial distribution formula, which is given by:

P(k;n,p) = C(n,k) * p^k * (1-p)^(n-k)

Where:

k is the number of successful outcomes, in this case the number of smartphone users who use their devices in meetings or classes
n is the total number of trials, in this case the total number of smartphone users we are selecting
p is the probability of success, in this case the probability that a smartphone user uses their device in meetings or classes
First, we need to calculate the probability that exactly 0 smartphone users use their devices in meetings or classes. This is given by:

P(0;15,0.49) = C(15,0) * 0.49^0 * (1-0.49)^15 = 0.26

Next, we need to calculate the probability that exactly 1 smartphone user uses their device in meetings or classes. This is given by:

P(1;15,0.49) = C(15,1) * 0.49^1 * (1-0.49)^14 = 0.33

Finally, we need to calculate the probability that exactly 2 smartphone users use their devices in meetings or classes. This is given by:

P(2;15,0.49) = C(15,2) * 0.49^2 * (1-0.49)^13 = 0.15

The probability of having fewer than 3 smartphone users among 15 users is given by the sum of the probabilities of having 0, 1, or 2 smartphone users, which is 0.26 + 0.33 + 0.15 = 0.74. This means that there is a 74% probability that fewer than 3 of the 15 selected smartphone users use their devices in meetings or classes.

The probability that fewer than 3 of the 15 smartphone users use their phones in meetings or classes is 7.46%.

What is the binomial probability theorem?

The binomial probability formula.

P(X = k) = [tex]^nC_r[/tex] [tex]P^k[/tex] [tex](1 - P)^{n - k}[/tex]

where n is the sample size, k is the number of successes, P is the probability of success, (P - 1) is the failure.

We have,

The required probability.

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

Where X is the number of smartphone users out of 15 who use their phones in meetings or classes.

Now,

Using the binomial probability.

P(X = k) = [tex]^nC_r[/tex] [tex]P^k[/tex] [tex](1 - P)^{n - k}[/tex]

where n is the sample size, k is the number of successes (using their smartphones in meetings or classes), p is the probability of success (49%), and (n choose k) is the number of ways to choose k successes out of n trials.

We get,

P(X = 0) = [tex]^{15}C_0[/tex] x [tex]0.49^0[/tex] x [tex]0.51^{15}[/tex] = 0.0018

P(X = 1) = [tex]^{15}C_1[/tex] x [tex]0.49^1[/tex] x [tex]0.15^{14}[/tex] = 0.0149

P(X = 2) = [tex]^{15}C_2 \times 0.49^2 \times 0.49^{13}[/tex] = 0.0579

The probability of fewer than 3 smartphone users using their phones in meetings or classes.

P(X < 3)

= P(X = 0) + P(X = 1) + P(X = 2)

= 0.0018 + 0.0149 + 0.0579

= 0.0746

= 0.0746 x 100

= 7.46%

Thus,

The probability that fewer than 3 of the 15 smartphone users use their phones in meetings or classes is 7.46%.

Marisol pours water into a large oven-safe glass bowl until it is about one-fourth full. She then places a small, heavy cup inside the glass bowl. The cup is heavy enough that it does not float. She makes sure that no water enters the small cup when she places it in the bowl. She then places the oven-safe bowl with the water and cup on an electric burner. Finally, she turns the burner on to low.


Part A

What will happen to the water in terms of phase changes when Marisol turns on the stove?


Part B

Marisol covers the bowl with plastic wrap and then places ice on top of the plastic wrap. Write a hypothesis predicting how the plastic wrap and ice cubes will affect the water vapor in the large bowl.


Part C

The image shows what happens when Marisol completes her setup.Write down what you observe in the image. Explain the processes that occur in the bowl and result in what you see.


- The picture here is for Part C -

Answers

Part A: When Marisol turns on the stove, the water in the bowl will begin to heat up. This will cause the water molecules to gain kinetic energy, causing them to move around more quickly. As the temperature of the water increases, the water molecules will begin to vibrate more rapidly, which may eventually cause the water to boil, depending on the temperature and pressure of the system.

Part B: I would expect that the plastic wrap and ice cubes will affect the water vapor in the large bowl by causing condensation to occur on the underside of the plastic wrap. The plastic wrap will act as a barrier to the water vapor, trapping it in the bowl and preventing it from escaping into the air. The ice cubes will cause the temperature of the system to decrease, which will lower the kinetic energy of the water molecules and cause them to slow down. This may cause some of the water vapor to condense and form liquid water droplets on the underside of the plastic wrap.

Part C: In the image, I see a large bowl with water in it, and a small cup floating in the water. There is a layer of condensation on the underside of a piece of plastic wrap that is covering the bowl. There are also a number of ice cubes on top of the plastic wrap. The processes that are occurring in the bowl are likely to be boiling and condensation. The heat from the electric burner is causing the water in the bowl to boil, and the steam that is produced is rising up and coming into contact with the colder plastic wrap, which causes the steam to condense and form droplets of liquid water on the underside of the plastic wrap. The ice cubes on top of the plastic wrap are likely to be helping to cool down the system, which may be contributing to the condensation that is occurring.

The water in the bowl will start to heat up when Marisol switches on the stove. The water molecules will receive kinetic energy as a result, which will speed up their movement.

What is Part C of Image?

Depending on the system's temperature and pressure, the water's molecules will start to vibrate more quickly as its temperature rises. This could eventually cause the water to boil.

Part B: I predict that the ice cubes and plastic wrap will alter the water vapor in the large bowl by causing condensation to form on the plastic wrap's underside.  

Part C: I see a large bowl of water with a small cup floating in it in the image. The plastic wrap that is covering the bowl has a film of dampness on the underside.

Therefore, The water in the bowl will start to heat up when Marisol switches on the stove. The water molecules will receive kinetic energy as a result, which will speed up their movement.

b) The probability of the panel consisting of at most 2 senior auditors is of: 0.6515 = 65.15%.

What is the hypergeometric distribution formula?

The mass probability formula is presented as follows:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

x is the number of successes.N is the size of the population.n is the size of the sample.k is the total number of desired outcomes.

The values of these parameters for this problem are given as follows:

[tex]N = 11, k = 6, n = 4[/tex]

The probability of the panel consisting of at least 3 senior auditors is given as follows:

P(X ≥ 3) = P(X = 3) + P(X = 4)

In which:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 3) = h(3,11,4,6) = \frac{C_{6,3}C_{5,1}}{C_{11,4}} = 0.303[/tex]

[tex]P(X = 4) = h(4,11,4,6) = \frac{C_{6,4}C_{5,0}}{C_{11,4}} = 0.0455[/tex]

Then the probability is of:

P(X ≥ 3) = P(X = 3) + P(X = 4) = 0.303 + 0.0455 = 0.3485 = 34.85%.

The probability of at most 2 senior auditors is of:

P(X ≥ 2) = 1 - P(X ≥ 3) = 1 - 0.3485 = 0.6515 = 65.15%.

The proportion allocated to the money market account will be at least double the amount in the CD c. The annual return will be 8% for bonds, 9% for the CD and 7% for the money market account. Assume that the investor wants to maximize the total annual return Accessibility: Investigate Get genuine Office Then, formulate the LP model for this problem, ignoring any transaction costs and the potential for different investment ​

Answers

Decision variables:

Let x be the amount invested in municipal bonds
Let y be the amount invested in the CD
Let z be the amount invested in the money market account
Objective function:

The investor wants to maximize the total annual return, which is the sum of the returns from the three investments. We can express this as 8x + 9y + 7z.
Constraints:

The investor has $100,000 to invest, so x + y + z ≤ 100,000
The investor wants to invest no more than 40% of the total amount in bonds, which translates to x ≤ 0.4 * (100,000) = 40,000
The proportion allocated to the money market account will be at least double the amount in the CD, which means z ≥ 2y
All variables must be non-negative, so x, y, and z ≥ 0
The LP model can be written as:

maximize 8x + 9y + 7z
subject to
x + y + z ≤ 100,000
x ≤ 40,000
z ≥ 2y
x, y, z ≥ 0

The LP model for the problem is x, y, z ≥ 0.

What is an investor?

An investor is a person or organization that uses its own money or money borrowed from others with the intention of making a profit.

Decision variables:

Let x be the amount invested in municipal bonds

Let y be the amount invested in the CD

Let z be the amount invested in the money market account

The investor has $100,000 to invest, so x + y + z ≤ 100,000

The investor wants to invest no more than 40% of the total amount in bonds, which translates to x ≤ 0.4 * (100,000) = 40,000

The LP model can be written as:

maximize 8x + 9y + 7z

subject to

x + y + z ≤ 100,000
