Answer:

your correct answer is d. 3/2

Step-by-step explanation:

Kevin's probability model for selecting one more student at random for the poll is as follows:

P(Yes) = 0.4

P(No) = 0.5

P(Undecided) = 0.1

We can see that 72 students stated they would vote yes, 90 said they would vote no, and 18 were unsure based on Kevin's random sample of students.

There are a total of students in sample 72 + 90 + 18 = 180.

So, the probability of selecting a student who would vote yes at random is 72 / 180 = 0.4.

The probability of selecting at random a student who would cast a " no vote is 90 / 180 = 0.5.

The probability of selecting a student who is undecided at random is      18 / 180 = 0.1.

Therefore, Kevin's probability model for selecting one more student at random for the poll is as follows:

P(Yes) = 0.4

P(No) = 0.5

P(Undecided) = 0.1

The total area of a pyramid is the sum of the areas of the triangular faces and the area of the base.

__

Here, each triangular face has a base of 5 in, and a slant height of 7 in. Its area will be given by the area formula for a triangle:

  A = 1/2bh

  A = 1/2(5 in)(7 in) = 35/2 in² . . . . area of one of four congruent faces

__

The area of the base is that of a square with 5-inch sides. It is given by the formula ...

  A = s²

  A = (5 in)² = 25 in²

__

Then the total surface area is .

  area of base + 4 × triangle area

  = 25 in² + 4(35/2 in²) = 95 in² . . . . . surface area of the pyramid

The value of QR when points P, Q, R and S are collinear is .13

We are given that:

Points P, Q, R and S are collinear points.

Also,

PS = 23

PR = 18

We need to find the value for QR.

Now, we have that PQ is congruent to RS.

So, This means that PQ = RS

This can also be written as:

PR - QR = RS

18 - QR = RS

Also,

PR + RS = PS

Substituting the values, we get that:

18 + ( 18 - QR ) = 23

18 - QR = 23 - 18

18 - QR = 5

QR = 18 - 5

QR = 13

Therefore, we get that, the value of QR when points P, Q, R and S are collinear is .13

The employee that had the largest dollar amount in sales for the month of December is (b) the straight commission employee

Commission is simply a payment that is paid to an employee, based on the sales made by the employee.

The table is given as:

Employee A: 2000+3% on all sales

                     December 4.4

Employee B: 7% on all sales

                      December 5.6

Employee C: 5% on the first 40,000+ 8% on anything over 40,000

                      December 5.2

The total pay received by each employee is calculated as follows:

\(A = 2000 + 3\% \times 44000 = 3320\)

\(B = 7\% \times 56000 = 3920\)

\(C = 5\% \times 40000 + 8\% \times (52000 - 40000) = 2960\)

By comparing the results of the above computation;

3920 is greater than 3320 and 2960

Hence, employee B received the largest amount in sales in December

Answer: 21.32

Step-by-step explanation: To figure out how many more cans each student needs to bring, we can use the following equation:

(total number of cans needed) - (number of cans collected) = (number of cans each student needs to bring) x (number of students)

So, plugging in the values we know, we get:

1,000 - 403 = x * 28

Simplifying the equation:

597 = 28x

Dividing both sides by 28:

x = 21.32

This means that each student needs to bring about 21 more cans (rounded up) to reach the goal of 1,000 cans.

But what I want you to know is, that you don't need to graph it.

We have to different x-values, 1 and 6. We know that. But since the sides are vertical, they are pairs. That's why there is a pair of coordinates that have an x-value of 1.

Similarly, we have pairs of y-values of -5, because they are horizontal sides.

Commonly, research begins with a straightforward random sample. This enables them to statistically analyze a sample of people drawn from a bigger population or group in order to simulate the response of the complete group.

Why does a field (a list of every person in the population) need to be included in simple random sampling?) :-

   - Simple random sample is the term used to describe a smaller portion    of a bigger population. Each person in this area has an equal probability of being selected. For this reason, a straightforward random sample is intended to be impartial in its portrayal of the wider group. This approach typically has an error margin, which is denoted by a plus or minus variant. An example of a sampling error is this.

why does the requirement of a field make collecting a simple random sample difficult :-

    - Only when a complete list of the entire population to be researched is available can a simple random sampling yield an accurate statistical measure of a big population. Consider a list of university students or a group of workers at a particular business.

The availability of these lists is the issue. Accessing the entire list can therefore be difficult. It's possible that some colleges or universities won't want to give researchers an exhaustive list of their faculty or students. Similar to this, some businesses might not be able or willing to provide information about particular employee groups due to privacy policies.

Typically, research starts with a simple random sample. This gives them the ability to statistically assess a group or population sample taken from a larger one in order to imitate the response of the entire group.

Why does simple random sampling require a field (a list of every person in the population)?

A smaller subset of a larger population is referred to as a simple random sample. Everyone in this area has an equal chance of being chosen. Because of this, a simple random sample is meant to represent the larger group objectively. An plus or minus variant is used to indicate the approach's typical error margin. This is an illustration of a sampling inaccuracy.

Why is it difficult to gather a simple random sample because of a field's requirements:-

- A simple random sample cannot produce an appropriate statistical measure of a large population unless the entire population to be studied is accessible. Think of a list of college students or a team of employees at a specific company.

The problem is the accessibility of these lists. It may be challenging to access the complete list as a result. Some schools and universities might not wish to provide a complete list of their faculty or students to researchers. Similar to this, due to privacy policies, some businesses might not be able or willing to provide information about specific employee groups.

We have been given that a cosine function is a reflection of its parent function over the x-axis. The amplitude of the function is 11, the vertical shift is 9 units down, and the period of the function is \(\frac{7\pi}{12}\). The graph of the function does not show a phase shift. We are asked to write the equation of our function.

We know that general form a cosine function is \(y=A\cos(b(x-c))-d\), where,

A = Amplitude,

\(\frac{2\pi}{b}\) = Period,

c = Horizontal shift,

d = Vertical shift.    

The equation of parent cosine function is \(y=\cos(x)\). Since function is reflected about x-axis, so our function will be \(y=-\cos(x)\).

Let us find the value of b.

\(\frac{2\pi}{b}=\frac{7\pi}{12}\)

\(7\pi\cdot b=24\pi\)

\(\frac{7\pi\cdot b}{7\pi}=\frac{24\pi}{7\pi}\)

\(b=\frac{24}{7}\)

Upon substituting our given values in general cosine function, we will get:

\(f(x)=-11\cos(\frac{24}{7}x)-9\)

Therefore, our required function would be \(f(x)=-11\cos(\frac{24}{7}x)-9\).

ANSWER:

14

EXPLANATION:

Given that a number is multiplied by seven, and the product is increased by two, the result is one hundred.

Let's express this mathematically(equation).

Let the number be represented by X.

A number X is multiplied by seven = 7X

The product is increased by 2 = 7X + 2

The result is 100 = 7X + 2 = 100

We have:

7X + 2 = 100

Solve for X:

Subtract 2 from both sides:

7X + 2 - 2 = 100 - 2

7X = 98

Divide both sides by 7:

Therefore the number is 14

The main answer for the first argument is that we cannot prove that the band could play rock music based on the given premises and rules of inference.

1. Let's assign the following propositions:

  - P: The band could play rock music.

  - Q: The refreshments were delivered on time.

  - R: The New Year's party was canceled.

  - S: Alicia was angry.

  - T: Refunds were made.

2. The given premises can be expressed as:

  (¬P ∨ ¬Q) → (R ∧ S)

  R → T

3. To prove that the band could play rock music (P), we need to derive it using valid rules of inference.

4. Using the premises, we can apply the rule of modus tollens to the second premise:

  R → T        (Premise)

  Therefore, ¬R.

5. Next, we can use disjunctive syllogism on the first premise:

  (¬P ∨ ¬Q) → (R ∧ S)     (Premise)

  ¬R                    (From step 4)

  Therefore, ¬(¬P ∨ ¬Q).

6. Applying De Morgan's law to step 5, we get:

  ¬(¬P ∨ ¬Q)  ≡  (P ∧ Q)

7. Therefore, we can conclude that the band could play rock music (P) based on the premises and rules of inference.
