Number of random numbers that is need to be generated to identify those subjects who are included in the sample is option (a) n

To select a systematic random sample, we need to randomly select a starting point within the population, and then select every kth element thereafter, where k is the sampling interval. The value of k can be calculated as:

k = N/n

So, to identify the subjects who are included in the sample, we only need to generate one random number to select the starting point, and then add k to it to identify the next sample element. We can continue this process until we have identified all the n sample elements.

Therefore, the number of random numbers needed to identify those subjects who are included in the sample is 1, plus the number of times we need to add k to the starting point to identify all n sample elements. This is:

1 + (n-1) = n

Therefore, the correct option is (a) n.

Answer:

Step-by-step explanation:

Given the inequality m > 225, the inequality means that m is greater than 225. Since the inequality sign does not include equal to sign, then the value of m cannot be less than and equal to 225. The situation that best fits the expression based on the explanation above is "The number of people who attended the mathematics conference was more than 225"

Emphasis should be on 'WAS MORE THAN' according to the statement. The greater sign means that the number of people will always be greater than or more than 225 representing the variable m as the number of people.

The expression (4x+8)² is equivalent to 16x²+64x+64 i.e.D.

What are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

Now,

Given expression is (4x+8)²

=(4x)²+8²+2*4x*8         As ((a+b)²=a²+b²+2ab)

=16x²+64+64x

hence,

          (4x+8)² is equivalent to 16x²+64x+64.

The probability of a female employee driving to work is 0.192, or 19.2%.

To determine the probability of a female employee driving to work, we need to find the intersection of the categories "female" and "drive" in the given table.

From the table, we have the following probabilities:

P(female) = 0.4 (probability of being female)

P(drive) = 0.48 (probability of driving to work)

P(female and drive) = ? (probability of being female and driving to work)

We can calculate the probability of being female and driving to work by multiplying the individual probabilities:

P(female and drive) = P(female) * P(drive) = 0.4 * 0.48 = 0.192

Therefore, the probability of a female employee driving to work is 0.192, or 19.2%.

A numerical measure computed from a sample, such as sample mean, is known as Sample statistic

What is Statistic?

The study of statistics focuses on gathering, organizing, organizing, analyzing, interpreting, and presenting data. It is customary to start with a statistical population or a statistical model to be researched when applying statistics to a scientific, industrial, or social problem.

A sample statistic is a metric that is calculated from a sample, such as sample mean. A population parameter is a numerical measure derived from a population, such as a mean.

Any value calculated from your sample data is referred to as a sample statistic (or simply a statistic). The sample average, median, sample standard deviation, and percentiles are a few examples. Because a statistic is based on data gathered through random sampling, which is a random experiment, it is a random variable.

The amount the is truly consumed is always larger than what is stated on the FFQ. Hence, it is the incorrect statement for the indicated correlation.

What is correlation?

To represent the relationship between continuous variables, correlation is utilized. A numerical value called the correlation illustrates the connection between two variables. The sign affects the kind of relationship that exists between the variables. A direct or positive association would result if the sign is positive. It would be detrimental otherwise.

The correlation is a number which indicates relationship between two variables.

A correlation is used to test the relationship between continuous variables.

A correlation coefficient has a value between -1 and 1 this means there is a perfect negative or positive correlation. These are very high correlation examples.

A positive correlation does not imply that what is truly consumed is always larger than what is stated on the FFQ.

A positive correlation coefficient only implies that with a change in diary readings, the food questionnaire reading will also change in the same manner.

However, this does not reflect anything on the true consumed values and therefore, it cannot be judged whether the truly consumed amount will be larger or not.

The provided options are analyzed by the fact that the positive correlation means the change in the variables is direct rather than indirect.

The positive correlation means the direct change in the variables. Hence, the option is an incorrect one.

The correlation only represents whether the two variables have a positive or negative relationship. It does not tell anything about whether one value is greater or not.

The number of ways to pick 6 people from a group of 10 so that the bride and groom must be next to each other is 8!4!4!⋅5!⋅2!

We can reduce your problem to a simpler one, as you claim that the bride must be in the picture. Now you have to select 5 people out of 9.

It's just 9!4!5!

Now it's just a matter of choosing the participants of the picture. Since there are 6 people in the picture, you can arrange 6 of them! ways. This leaves the total number of possible combinations 9!4!5!⋅6!

I would also like to discuss another possible option of 6 people from a group of 10 where 2 of the 6 must be the bride and groom and must be next to each other. I can see it coming in a similar situation.

This has a familiar beginning. We already know 2 of the 6 people, so only 4 left to choose from the remaining 8. This is given by 8!4!4!.

Now we need to permute the group of 6 participants. One would like to say that this is simply a 6! like the first problem, but it's a little different. Remember that the bride and groom must be next to each other. You can basically think of these two people as one person.

So the actual number of ways to permute this group of 6 people with a constraint is 5! . There is one more condition. If you don't subscribe to the opinion that the groom must always be on the left (facing the couple), you have two options to arrange our couple.

The limit of the sequence is 0.

To determine the limit of the sequence, we can use the Limit Laws and theorems. We will start by simplifying the expression:

cn=ln((5n-7)/(12n+4))

cn=ln(5n-7)-ln(12n+4)

Now we can use the Limit Laws:

lim n→∞ ln(5n-7) = ∞ (since ln(x) → ∞ as x → ∞)

lim n→∞ ln(12n+4) = ∞ (since ln(x) → ∞ as x → ∞)

Therefore, we have:

lim n→∞ cn = lim n→∞ (ln(5n-7)-ln(12n+4))

= lim n→∞ ln(5n-7) - lim n→∞ ln(12n+4)

= ∞ - ∞ (which is an indeterminate form)

To evaluate this limit, we can use L'Hopital's Rule:

lim n→∞ ln(5n-7) - ln(12n+4) = lim n→∞ [ln((5n-7)/(12n+4))]

= lim n→∞ [(5/12)/(5/n - 3/4n²)]

Since the denominator goes to ∞ and the numerator is constant, we have:

lim n→∞ [(5/12)/(5/n - 3/4n²)] = 0

Therefore, we have:

lim n→∞ cn = 0

So the limit of the sequence is 0.

The process is capable of producing outputs within the specification limits is true.

There are a number of potential reasons for why the process is not meeting the target value. One possibility is that the target value is too ambitious and is not realistic given the current process capability. Another possibility is that there is some inherent variability in the process that is not being accounted for. It is also possible that there are some external factors that are affecting the process, such as changes in the raw materials or the environment.

The design engineers have established an upper specification limit of 22 and a lower specification limit of 18. This means that they are confident that the process is capable of producing outputs within these limits. However, the fact that the process is consistently averaging 19.8 with a standard deviation of 0.5 suggests that there is some room for improvement.

One potential way to improve the process is to focus on reducing the inherent variability. This can be done by identifying and addressing the sources of variability in the process. Another potential way to improve the process is to reduce the target value. This may be necessary if the current target value is not realistic given the process capability.

It is also important to monitor the process over time to ensure that it is remaining within the specification limits. This will help to identify any potential issues that may arise and allow for corrective action to be taken if necessary.

If Fothergill Company decides to purchase the part from the outside supplier at a cost of $57.10 per unit, it would avoid the direct materials, direct labor, and variable manufacturing overhead costs associated with producing the part internally.

However, a portion of the fixed manufacturing overhead cost, specifically $21.90 per unit, would still be incurred even if the part is purchased externally. This fixed manufacturing overhead cost would be allocated to the company's remaining products.

Let's calculate the total cost savings and additional contribution margin if the company decides to purchase the part from the outside supplier:

Cost savings per unit:

Direct materials: $21.40

Direct labor: $22.30

Variable manufacturing overhead: $1.40

Total variable costs per unit: $45.10

Cost savings for 40,000 units: $45.10 * 40,000 = $1,804,000

Fixed manufacturing overhead cost allocated to remaining products: $21.90 * 40,000 = $876,000

Additional contribution margin from producing more units of the high-demand product: $395,000

Total net savings and additional contribution margin:

$1,804,000 + $395,000 - $876,000 = $1,323,000

Therefore, if the company accepts the outside supplier's offer and purchases the part externally, it would save a total of $1,323,000 per year and generate an additional contribution margin for its high-demand product.

The vector <-32, 44, 22> is parallel to the line of intersection of the two planes given by the equations 2x - 3y + 5z = 2 and 4x + y - 3z = 7.

To find a vector parallel to the line of intersection of the planes given by the equations 2x - 3y + 5z = 2 and 4x + y - 3z = 7, we first need to find the direction vector of the line of intersection.

We can find the direction vector by taking the cross product of the normal vectors of the two planes. The normal vector of the plane 2x - 3y + 5z = 2 is <2, -3, 5>, and the normal vector of the plane 4x + y - 3z = 7 is <4, 1, -3>. Taking the cross product of these two vectors, we get:

<2, -3, 5> × <4, 1, -3> = <-16, 22, 11>

This vector <-16, 22, 11> is the direction vector of the line of intersection of the two planes.

To find a vector parallel to this line, we can simply multiply the direction vector by a scalar. For example, we can choose a scalar of 2 to get:

2<-16, 22, 11> = <-32, 44, 22>

Therefore, the vector <-32, 44, 22> is parallel to the line of intersection of the two planes given by the equations 2x - 3y + 5z = 2 and 4x + y - 3z = 7.

The point at which the direction of fastest change of the function f(x, y) = x² + y² - 2x - 6y is in the direction of vector i + j is (3/2, 7/2).

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

To find the points at which the direction of fastest change of the function f(x, y) = x² + y² - 2x - 6y is in the direction of vector i + j, we need to find the gradient vector of the function and equate it to the given direction vector.

The gradient vector of the function f(x, y) is given by:

∇f(x, y) = [∂f/∂x, ∂f/∂y]

Taking partial derivatives of f(x, y) with respect to x and y:

∂f/∂x = 2x - 2

∂f/∂y = 2y - 6

Setting the gradient vector equal to the given direction vector i + j:

[2x - 2, 2y - 6] = [1, 1]

Equating the corresponding components, we have:

2x - 2 = 1

2y - 6 = 1

Solving these equations, we get:

2x = 3  =>  x = 3/2

2y = 7  =>  y = 7/2

Therefore, the point at which the direction of fastest change of the function f(x, y) = x² + y² - 2x - 6y is in the direction of vector i + j is (3/2, 7/2).
