All the elements in DUE are {16,18,19,20,21}. And the elements are combined elements of D and E.

The set containing all the components that are present in both sets A and B, or both sets A and B combined, is referred to as the union of two sets A and B. The symbol "aUb" stands for the union of the sets a and.

Given, sets D = {16,19.21},

E = {16,18, 19,20},

and F = {15, 17, 18,19,21}.

To find the elements in the set DUE:

Here, we have to find the collection of sets D and E

And we have the elements of,

D = {16,19.21}

And E = {16,18, 19,20}.

To find the union of sets, we take all the elements in the union set.

And while doing, we should not repeat the elements.

And put the elements in the ascending order.

So, the union of set D and E is,

DUE = {16,18,19,20,21}

Therefore, the DUE is {16,18,19,20,21}.

When the radius is 2 feet, the rate of change of the radius is approximately 0.089 ft/min (rounded to three decimal places).

To find the rate of change of the radius when the radius is 2 feet, and air is being pumped into a spherical balloon at a rate of 4.5 cubic feet per minute, we can use the following steps:
Determine the volume formula for a sphere: V = (4/3)πr³.

Differentiate the volume formula with respect to time (t) to find dV/dt: dV/dt = d((4/3)πr³)/dt.
Apply the chain rule: dV/dt = (4/3)π(3r²)(dr/dt).
Simplify the equation: dV/dt = 4πr²(dr/dt).
Solve for the rate of change of the radius (dr/dt): dr/dt = dV/dt / (4πr²).
Plug in the given values: dV/dt = 4.5 cubic feet per minute and r = 2 feet.
Calculate the rate of change of the radius (dr/dt): dr/dt = 4.5 / (4π(2²)).
Simplify and compute the answer: dr/dt = 4.5 / (16π).
When the radius is 2 feet, the rate of change of the radius is approximately 0.089 ft/min (rounded to three decimal places).

Answer: The answer is 9/25. (36%)

Step-by-step explanation:

Since we know that 7/25 workers walk and 2/25 walk, we can do simple addition to find the total Percentage. This equals 9/25. To find the percentage, do the following:

Write 9/25 into a percentage: Divide

9 / 25 x (100%) = 36%

0.36 (100%) = 36%

Therefore 36% is your answer.

To compute the truth table for --P<->Q, we need to first understand the meaning of the logical operator "<->". This operator stands for "if and only if" and it is true only when both statements are either true or false.

In other words, if P is true and Q is true or if P is false and Q is false, then the statement is true. If P is true and Q is false or if P is false and Q is true, then the statement is false.

Using canonical form, we can write the statement --P<->Q as (P v ~Q) ^ (~P v Q), where ^ stands for "and" and v stands for "or". The negation of P is represented by ~P.

Now, we can construct the truth table with the four possible combinations of truth values for P and Q. Labeling each row from 1 to 4, we have:

Row 1: P is true, Q is true
Row 2: P is true, Q is false
Row 3: P is false, Q is true
Row 4: P is false, Q is false

Next, we evaluate the canonical form for each row. For example, in row 1, we have (true v ~true) ^ (~true v true), which simplifies to true ^ true, resulting in a truth value of true. Continuing this process for all four rows, we get:

Row 1: true
Row 2: false
Row 3: false
Row 4: true

Therefore, the truth table for --P<->Q using canonical form is:

| P | Q | --P<->Q |
|---|---|---------|
| T | T |    T    |
| T | F |    F    |
| F | T |    F    |
| F | F |    T    |

The first column represents the truth values for P, the second column represents the truth values for Q, and the third column represents the truth values for --P<->Q. The answer is more than 100 words and includes the requested term "canonical form".

The simplified expression is \(x^\frac{1}{4}\) x \(y^\frac{1}{2}\).

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

\(\sqrt[8]{x^2y^4}\)

This can be written as,

= \(\sqrt[8]{x^2}\) x \(\sqrt[8]{y^4}\)

= \(x^\frac{1}{4}\) x \(y^\frac{1}{2}\)

Thus,

Time taken by Matilda on each project is \(5\frac{7}{12}\) hours.

According to the question we have been given that,

Total time taken by Matilda to complete the consulting projects = \(16\frac{3}{4}\) hours

First we will convert it into simple fraction which is

         \(16\frac{3}{4} = \frac{67}{4} \\\) hours

Number of consulting projects = 3

And Matilda spends same amount of time to each of the project.

To find the time she spend on each project is by using unitary method

that is,            3 projects = \(\frac{67}{4}\) hours

                      1 project = \(\frac{67}{4} / 3\)

                                     = 67/12

                                     = \(5\frac{7}{12}\) hours

Hence time taken by Matilda on each project is \(5\frac{7}{12}\) hours.

Answer:

Yes, it is possible for a dataset to have more than one mode.

Step-by-step explanation:

In statistics, a mode refers to the value or values that occur most frequently in a dataset. If there are multiple values that have the same highest frequency and occur more frequently than any other value in the dataset, then the dataset is said to have multiple modes.

There are different types of distributions that can exhibit multiple modes. Here are a few examples:

Bimodal Distribution: A bimodal distribution has two distinct modes, meaning it has two peaks or high-frequency regions. This indicates that there are two different groups or subpopulations within the dataset, each with its own characteristic values. For example, if you have a dataset of heights that includes both adults and children, you may observe two modes corresponding to the adult and child heights.

Multimodal Distribution: A multimodal distribution has more than two modes, meaning it has multiple peaks or high-frequency regions. This suggests the presence of multiple subgroups or distinct characteristics within the dataset. For instance, if you have a dataset of exam scores for a class where some students performed well, some performed moderately, and some performed poorly, you might observe three modes corresponding to these groups.

No Mode: It is also possible for a dataset to have no mode, which occurs when no value appears more frequently than others. This can happen in datasets with uniform or random distributions, where all values have equal frequency.

It's important to note that not all datasets will have a mode or multiple modes. Some datasets may have a single mode where one value occurs with the highest frequency, while others may have no discernible mode if the values are evenly distributed or there is no repetitive pattern in the data.In summary, a dataset can have one mode, multiple modes, or no mode depending on the frequency distribution of its values. The presence of multiple modes indicates the existence of distinct groups or subpopulations within the data.

Arranged from least likely to most likely

- Event 4. choosing a yellow marble from bag B​

- Event 3. choosing a blue marble from bag B

- Event 4 choosing a blue marble from bag A

Explanation

Bag A

4 blue marbles and 6 black marbles.

Bag B

6 blue marbles and 14 black marbles.

So, to arrange given cases in the order of least likely to most likely, we need to find the probabilities of each of them.

Event 1. choosing a blue or black marble from bag B

This would entail picking bag B first, then picking from either blue or black ball first. Since all the balls in the bag are either black. So, the probability is given as

Probability

= (Probability of picking one type of bag) (Probabiliy that the ball is either blue or black)

= (0.5) (1)

= 0.5

Event 2. choosing a blue marble from bag A

Probability

= (Probability of picking bag A) (Probabiliy that the ball is blue from A)

= (0.5) (4/10)

= (0.5) (0.4)

= 0.2

Event 3. choosing a blue marble from bag B

Probability

= (Probability of picking bag B) (Probabiliy that the ball is blue from B)

= (0.5) (6/20)

= (0.5) (0.3)

= 0.15

Event 4. choosing a yellow marble from bag B​

Probabiliity

= ((Probability of picking bag B) (Probabiliy that the ball is yellowfrom B)

= (0.5) (0/20)

= 0.5 (0)

= 0

0 < 0.15 < 2 < 0.5
