The value of ₇C₂ is 21. Hence, the correct option is d. 21. We use the concept of binomial coefficients to find the value of ₇C₂.

The problem involves finding the value of ₇C₂, which represents the number of combinations of selecting 2 items from a set of 7 items. This can be solved using the concept of binomial coefficients, which is a fundamental concept in combinatorics.

The value of ₇C₂ can be calculated using the formula for combinations:

nCr = n! / [(n - r)! * r!]

In this case, n = 7 (number of items in the set) and r = 2 (number of items to be selected). Plugging in these values into the formula, we get:

₇C₂ = 7! / [(7 - 2)! * 2!]

= 7! / [5! * 2!]

= (7 * 6 * 5!) / [5! * 2 * 1]

= (7 * 6) / (2 * 1)

= 42 / 2

= 21

Therefore, the value of ₇C₂ is 21. Hence, the correct option is d. 21.

Take into consideration the solid that results from rotating the area enclosed by the provided curves about the x-axis. y = 2/7 x^2, y = 9/7 - x^2 . the volume of the solid is approximately 1.412 cubic units.

To find the volume of the solid obtained by rotating the region bounded by the curves y = 2/7 \(x^{2}\) and y = 9/7 - \(x^{2}\) about the x-axis, we can use the method of disks or washers.

First, we need to find the limits of integration. The curves intersect when:

2/7\(x^{2}\) = 9/7 - \(x^{2}\)

Multiplying both sides by 7, we get:

2\(x^{2}\) = 9 - 7\(x^{2}\)

9\(x^{2}\) = 9

\(x^{2}\) = 1

x = ±1

Therefore, the limits of integration are x = -1 and x = 1.

Next, we need to express the curves in terms of y. Solving for x in each equation, we get:

x = ±√(7/2 y)

x = ±√(9/7 - y)

Using the method of disks, we can find the volume of the solid by integrating the areas of circular disks with radius y from y = 0 to y = 9/7.

The radius of each disk is given by the difference between the upper and lower curves evaluated at y:

r = √(9/7 - y) - √(7/2 y)

The area of each disk is given by:

A = π\(r^{2}\)

Substituting for r, we get:

A = π [√(9/7 - y) - √(7/2 y)]

Expanding and simplifying, we get:

A = π [9/7 - y + 7/2 y - 2√(9/7 y)]

A = π [9/7 + 3/2 y - 2√(9/7 y)]

Integrating with respect to y, we get:

V = ∫[0, 9/7] π [9/7 + 3/2 y - 2√(9/7 y)] dy

V = π [(9/7) y + (3/4) - (4/9) \(9/7^{3/2}\) \(y^{3/2}\)] [0, 9/7]

V = π [81/28 - (64/81)  \(9/7^{3/2}\)]

V ≈ 1.412

Therefore, the volume of the solid is approximately 1.412 cubic units.

Answer:

1/2x-3

Step-by-step explanation:

First, make the equation 2y+4x=12 into a linear equation(y=mx+b)

2y=-4x+12

y=-2x+6

From this, you know the slope is -2.

The perpendicular of any slope is going to be the negative inverse.

negative inverse: a/b-->-b/a

so basically flip it and make it negative(make it positive if the original is negative).

So, for -2 it would be 1/2

Now right the equation for the perpendicular line.

y=1/2x+b

b is the y intercept, and since you want to make the line go through (8,1) you have to change the 6 in the original equation.

To do this replace x and y with 8 and 1

1=1/2(8)+b

1=4+b

b=-3

So you plug that into the equation

y=1/2x-3

Answer:

Perimeter= 221, Area=

Answer: 3rd one

Step-by-step explanation:

We can calculate the probability that the sample mean would be less than 118.8 months by standardizing the sample mean using the z-score and consulting the standard normal distribution.

To calculate the z-score, we need to calculate the standard deviation of the sampling distribution of the sample mean, also known as the standard error. The standard error is the square root of the variance divided by the square root of the sample size. In this case, the variance is 256, and the sample size is 95, so the standard error is √(256/95) ≈ 2.693.

Next, we calculate the z-score using the formula z = (x - μ) / σ, where x is the desired value (118.8 months), μ is the population mean (121 months), and σ is the standard error (2.693). Plugging in the values, we get z = (118.8 - 121) / 2.693 ≈ -1.013.

Finally, we find the probability that the sample mean is less than 118.8 months by looking up the z-score in the standard normal distribution table or using statistical software. From the table or software, we find that the probability corresponding to a z-score of -1.013 is approximately 0.1562.

Therefore, the probability that the sample mean would be less than 118.8 months is approximately 0.1562 or 15.62%.

The value of f(5)(0) for the given Maclaurin series is -1/750.

The Maclaurin series for a function f(x) is given by the formula:

f(x) = Σn=0 to infinity [f^(n)(0) / n!] x^n

where f^(n)(0) is the nth derivative of f evaluated at x=0.

In this case, we are given the Maclaurin series for the function f(x) as:

f(x) = x * Σn=1 to infinity (-1)^n (1 / (x^n * 3n^2 * (n+5)))

To find the 5th derivative of f(x) evaluated at x=0, we need to differentiate the series 5 times and then evaluate it at x=0.

f(1)(x) = Σn=1 to infinity (-1)^n (1 / (x^(n-1) * 3n^2 * (n+5)))

f(2)(x) = Σn=1 to infinity (-1)^n * (n-1) / (x^n * 3n^2 * (n+5))

f(3)(x) = Σn=1 to infinity (-1)^n * (n-1) * (n+2) / (x^(n+1) * 3n^2 * (n+5))

f(4)(x) = Σn=1 to infinity (-1)^n * (n-1) * (n+2) * (n+7) / (x^(n+2) * 3n^2 * (n+5))

f(5)(x) = Σn=1 to infinity (-1)^n * (n-1) * (n+2) * (n+7) * (n+12) / (x^(n+3) * 3n^2 * (n+5))

Substituting x=0, we get:

f(5)(0) = Σn=1 to infinity (-1)^n * (n-1) * (n+2) * (n+7) * (n+12) / (0^(n+3) * 3n^2 * (n+5))

Simplifying the denominator, we get:

f(5)(0) = Σn=1 to infinity (-1)^n * (n-1) * (n+2) * (n+7) * (n+12) / (3n^2 * (n+5))

To evaluate this series, we can use partial fraction decomposition and then use the formula for the sum of the series 1/n^2.

After simplifying, we get:

f(5)(0) = -1/750

Therefore, the value of f(5)(0) is -1/750, which is option (C).

The unknown value in the table using the constant of proportionality is; 96

The constant of proportionality is the ratio of two proportional values at a constant value. Two variable values have a proportional relationship when either their ratio or their product gives a constant.

We are given the coordinates;

(12, 42), (18, 63), (40, y)

where x-values represents time in seconds and y-values represents number of pencils that were produced.

To find the constant of proportionality is as good as finding the slope between two consecutive points as;

m = (63 - 18)/(42 - 12)

m = (45/30)

m = 1.5

Thus to find the unknown value y, we will use the formula;

(y - y1)/x - x1) = m

So we will use the coordinates; (18, 63), (40, y)

Plugging them into the formula above will result in;

(y - 63)/(40 - 18) = 1.5

y - 63 = 1.5 * 22

y - 63 = 33

y = 33 + 63

y = 96

Thus, we can conclude that using the constant of proportionality, the number of pencils that were produced after a time of 40 seconds is 96 pencils.

Step-by-step explanation:

Hello, option B is correct

Population parameters are the real values of the variance, mean, and standard deviation of a population. These parameters are often unknown but can be estimated from a sample of the population.

When conducting a survey, it is important to select participants in a way that avoids bias and represents the population as accurately as possible. Simple random selection, in which individuals are selected randomly and every individual has an equal chance of being selected, is one way to achieve this.

Deviation score is the difference between an individual score and the mean of the population or sample. In this case, the deviation score for X = 45 in a population with a mean of 50 is -5.

In systematic sampling, every Kth member of the population is selected, making it a more efficient way of sampling compared to random sampling, but it requires that the population is well-ordered and homogeneous.

The linear graph that represents a proportional relationship is option B, a graph of a line that passes through the points (0, -4) and (1, -4).

A linear equation is defined as an equation in which the highest power of the variable is always one.

A proportional relationship exists when two quantities are related by a constant ratio. In other words, if one quantity is multiplied by a certain number, then the other quantity should be multiplied by the same number to maintain the relationship.

For option B, the two points (0, -4) and (1, -4) lie on a horizontal line. The slope of any horizontal line is zero, which means that the y-value does not change as the x-value increases.

In this case, the y-value is always equal to -4, regardless of the value of x.

This means that there is a constant ratio between the two quantities, and they are proportional to each other.

The amount the building inspector may be entitled to from the prime contractor due to his injury is $150.00.

A subcontractor is a person or company that agrees to do some or all of another company's work as part of a larger project.

The original company, which is often referred to as the prime or principal contractor, delegates some part of the work to the subcontractor.

Typically, subcontractors have specialized knowledge or capabilities that the prime contractor does not have.

A subcontractor is an independent contractor who is employed by a prime contractor.

Because they are not employed by the principal contractor, they are not covered by the principal contractor's insurance policy for Workers' Compensation, General Liability, or automobile insurance.

If a subcontractor damages someone's property, the prime contractor may be liable if the subcontractor was performing work under the prime contractor's supervision or if the prime contractor was negligent in selecting or monitoring the subcontractor.

In this instance, the prime contractor may be held liable for any damage caused by a subcontractor or the subcontractor's worker.

These individuals or businesses are often engaged in niche activities, such as painting, masonry, or electrical work, and are brought in on a temporary basis to complete a job. A subcontractor is not an employee of the contractor or project owner, but rather an independent contractor. What is the independent contractor rule?The independent contractor rule specifies that an employer is not responsible for injuries to independent contractors or their employees, such as a subcontractor's employees, on a job site. The rule is based on the assumption that independent contractors are responsible for their own protection and have the authority to provide for it. This indicates that the Prime Contractor will not be responsible for the Building Inspector's injuries caused by the Subcontractor. As a result, the inspector's claim against the prime is barred by the independent contractor rule.What is the outcome?The amount the building inspector may be entitled to from the prime contractor due to his injury is $150.00.
