The expression (n²)⁹ (n⁻⁹)⁻² (n⁻⁶)⁻³ (n⁻³)⁶ can be simplified as 1/n¹⁸.

To simplify the given expression, let's work on each factor separately:

\((n^2)^9:\) When we raise a power to another power, we multiply the exponents.

Therefore,\((n^2)^9\) simplifies to \(n^{(2 \times 9)} = n^{18\)

\((n^{(-9)})^{-2}:\) When we raise a negative exponent to another power, it becomes positive.

Therefore,\((n^{(-9)})^{-2}\) simplifies to \(n^{(9 \times {-2})} = n^{(-18)}.\)

\((n^{(-6)})^{-3}:\) Similar to the previous step, when we raise a negative exponent to another power, it becomes positive.

Thus, \((n^{(-6)})^{-3}\) simplifies to \(n^{(6 \times -3) }= n^{(-18)}.\)

\((n^{(-3)})^6:\) Once again, we raise a negative exponent to another power, making it positive.

Therefore,\((n^{(-3)})^6\)  simplifies to \(n^{(3 \times 6)}= n^{18}.\)

Now, let's combine all the simplified factors:

\((n^2)^9 \times (n^{(-9)})^-2 \times (n^{(-6)})^-3 \times (n^{(-3)})^6\)

\(= n^{18} \times n^{18} \times n^{18}\times n^{18}\)

When we multiply variables with the same base, we add the exponents. Therefore, the expression simplifies to:

\(n^{(18 + 18 + 18 + 18) }= n^{72\)

So, the given expression simplifies to \(n^{72}.\)

Given that:

Money spent on clothing last month = $40

Money spent this month is 120% of the spending of the last month.

To find:

A proportion to model this situation.

And the spending done this month?

Solution:

Let us have a look at 120% first.

\(120\%= \dfrac{120}{100} = \dfrac{6}{5}\)

\(\frac{6}{5}\) of \(x\) can be found by comparing \(x\) with 5, then we have to find the equivalent of 6.

Here, \(x\) is 40.

5 parts are equivalent to 40

1 part is equivalent to \(\frac{40}{5} = 8\)

6 parts are equivalent to \(8\times 6 = 48\)

I think its Z (-5, 7)

Step-by-step explanation:

Here :)

The coordinates of Z is (7, -5).

Given that, Z'(5, -7) is the image of Z after a reflection in the line y=x.

We need to find the coordinates of Z.

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

So, the coordinates of Z become (7, -5).

The probability of household views between 5 and 11 hours will be 0.7653. Number of hours needed in order to be in top 3% will be 13.03 hours. Probability of views more than 3 hours will be 0.9838.

a) The probability of television views between than 5 and 11 hours.

 P( 5≤X≤11) = P[ (5-μ)/σ ≤ (X-μ)/σ ≤ (11-μ)/σ]

                   = P [ (5-8.35)/2.5 ≤ z ≤ (11-8.35)/2.5)

                    = P ( -1.34 ≤ z ≤ 1.06)

                    = P ( z≤ 1.06) - P(z ≤ -1.34)

Substituting values from the z-table

   P ( 5≤X≤11) = 0.85543 - 0.09012 = 0.76531

Probability that household views between 5 and 11 hours is  0.7653.

b) Hours needed to be in top 3% of all households.

 P( X> h) = 0.03

 P[ (X-μ)/σ > (h-μ)/σ] = 0.03

P ( z >h-8.35/2.5) = 0.03

P ( z ≤ h-8.35/2.5) = 0.97

From the table

  (h - 8.35)/ 2.5 = 1.87

   h = (1.87× 2.5) + 8.35

      = 13.025 = 13.03 hours

So if the viewing time is more than 13.03, the household will be in the top 3%.

c) Probability of viewing more than 3 hours

 P(X> 3) = P[ (X-μ)/σ > (3-μ)/σ]

               = P( z < -2.14) = 0.9838

So probability the household will have views more than 3 hours will be 0.9838.

The generating function for the sequence {an} is given by a(x) = (1 + 2x) / (1 - x - 6x^2). It captures the terms of the sequence {an} as coefficients of the powers of x.

To find the generating function of the sequence {an}, we can use the properties of generating functions and solve the given recurrence relation.

The given recurrence relation is: an = an-1 + 6an-2

We are also given the initial conditions: a0 = 1 and a1 = 3.

To find the generating function, we define the generating function A(x) as:

a(x) = a0 + a1x + a2x² + a3x³ + ...

Multiplying the recurrence relation by x^n and summing over all values of n, we get:

∑(an × xⁿ) = ∑(an-1 × xⁿ) + 6∑(an-2 × xⁿ)

Now, let's express each summation in terms of the generating function a(x):

a(x) - a0 - a1x = x(A(x) - a0) + 6x²ᵃ⁽ˣ⁾

Simplifying and rearranging the terms, we have:

a(x)(1 - x - 6x²) = a0 + (a1 - a0)x

Using the given initial conditions, we have:

a(x)(1 - x - 6x²) = 1 + 2x

Now, we can solve for A(x) by dividing both sides by (1 - x - 6x^2²):

a(x) = (1 + 2x) / (1 - x - 6x²)

Therefore, the generating function for the given sequence is a(x) = (1 + 2x) / (1 - x - 6x²).

Cumulative distribution function (CDF) is an important concept in probability theory. The cumulative distribution function for the probability density function is the cumulative sum of probabilities. To find the cumulative distribution function for the probability density function \( f(x)=\frac{x^{2}}{63} \) on the interval \( [3,6] \).

we need to integrate this probability density function, we can integrate it as follows

\(:$$F(x)=\int_{-\infty}^{x} f(x) dx$$\)

Given the probability density function is

\(\( f(x)=\frac{x^{2}}{63} \) on the interval \( [3,6] \),\)

thus we can integrate it as follows:

$$F(x)=\int_{-\infty}^{x} \frac{x^{2}}{63}dx$$

Taking the integral of this probability density function, we get:

\($$F(x)=\frac{1}{63} \int_{3}^{x} x^{2} dx$$$$F(x)=\frac{1}{63} \left[\frac{x^{3}}{3} - \frac{3^{3}}{3}\right]$$$$F(x)=\frac{x^{3} - 27}{189}$$\)

Step-by-step explanation:

The histograms demonstrate that as sample size increases, the distribution of sample means becomes more normal, which is in line with the central limit theorem.

Histograms can be used to graphically represent a probability distribution, which is a measure of how likely it is that a random variable will take on a particular value.

The central limit theorem states that as the sample size increases, the sampling distribution of the mean approaches a normal distribution, regardless of the shape of the population distribution.

The histograms demonstrate this by showing the distribution of sample means for different sample sizes. As the sample size increases, the shape of the histogram becomes more normal, with a narrower and taller distribution.

Therefore, this demonstrates that the central limit theorem holds true, as the distribution of sample means becomes more normal as sample size increases, regardless of the shape of the population distribution.

Step-by-step explanation:

Chris and Mary, who live 14 miles apart, will meet after apart, will meet after a certain number of hours. Chris walks at a rate of 3 mph, and Mary walks at a rate of 4 mph.

To determine the number of hours it takes for Chris and Mary to meet, we can use the concept of relative speed. The relative speed is the sum of their individual speeds, which is 3 mph + 4 mph = 7 mph.

Since they are walking towards each other, their combined speed of 7 mph represents the rate at which the distance between them is decreasing. The distance between them is initially 14 miles. We can use the formula: time = distance / speed to find the number of hours it takes for them to meet.

Applying the formula, time = 14 miles / 7 mph = 2 hours. Therefore, Chris and Mary will meet after 2 hours of walking.

The concept of relative speed helps us determine how the distance between two objects changes over time when they are moving towards each other.

By considering their individual speeds and using the formula for time, we can calculate the time it takes for Chris and Mary to meet. In this case, their combined speed of 7 mph allows them to cover the initial distance of 14 miles in 2 hours, resulting in their meeting point

  (x, y) = (3, -7)

Step-by-step explanation:

You want to solve these equations, -x+y=-10 and 3x+4y=-19, using elimination.

The "elimination" method of solving a system of equations combines the equations in such a way that one of the variables is eliminated. Here, we can eliminate the x-variable by adding 3 times the first equation to the second:

  3(-x+y) +(3x+4y) = 3(-10) +(-19)

  7y = -49 . . . . . . . . . simplify; note x is eliminated from the equation

  y = -7 . . . . . . . . . . . divide by 7

The value of x can be found from the first equation by substituting for y:

  -x +(-7) = -10

  x = 10 -7 = 3 . . . . . . . add x+10 to both sides

The solution to these equations is (x, y) = (3, -7).

The solution is x=3, y = -7

From the question, we have

-x+y=-10 ...........(i)

3x+4y=-19 ..............(ii)

Multiplying equations (i) by 3, we get

-3x+3y=-30................(iii)

Adding both the equation (ii) and (iii), we get,

3x+4y-3x+3y  = -19-30

⇒7y = -49

⇒y = -7

Substituting the value of y in equation (i), we get

-x+y=-10

⇒-x-7=-10

⇒x=3

Elimination Method:

One method for resolving a system of linear equations is the elimination method. In this approach, the equation in one variable is obtained by either adding or subtracting the equations. We can add the equation to delete a variable if its coefficients are the same and have the opposite sign from the other variables. Similar to this, we can subtract the equation to get the equation in one variable if the coefficients of one of the variables are the same and their signs are the same.

Decomposition is used to perform ANOVA and test the significance of the independent variable and its interaction effect on the dependent variable.

The expression SS stands for "sum of squares", which is a statistical concept used in analysis of variance (ANOVA) to quantify the variation in a dataset. The components of this expression, a, b, c, and d, represent different sources of variation in the dataset, and their meanings are as follows:

a. (df)(s^2): This component represents the sum of squares due to the effect of the independent variable, also known as the factor or treatment. It is calculated by multiplying the degrees of freedom (df), which is the number of levels of the factor minus one, by the variance of the data within each level (s^2). This component quantifies the amount of variation in the dependent variable that can be explained by the independent variable.

b. (df)(s): This component represents the sum of squares due to the interaction between the independent variable and other factors, also known as the interaction effect. It is calculated by multiplying the degrees of freedom (df) by the standard deviation (s) of the data. This component quantifies the amount of variation in the dependent variable that is due to the joint effect of the independent variable and other factors.

c. (n)(s^2): This component represents the sum of squares due to the variation within groups, also known as the error or residual sum of squares. It is calculated by multiplying the sample size (n) by the variance of the data within each group (s^2). This component quantifies the amount of variation in the dependent variable that is not explained by the independent variable or other factors.

d. (n)(s): This component represents the sum of squares due to the variation between the sample mean and the overall mean, also known as the total sum of squares. It is calculated by multiplying the sample size (n) by the standard deviation (s) of the data. This component quantifies the total amount of variation in the dependent variable.

In summary, the expression SS = a. (df)(s^2) + b. (df)(s) + c. (n)(s^2) + d. (n)(s) represents the decomposition of the total sum of squares into its components due to the independent variable, interaction effect, error, and total variation.

The given statement is false becasue If the p-value of the coefficient of an X variable in a regression is 0.001, then it suggests that there is significant evidence that the coefficient is different from 0 in the population regression line.

A p-value is a value that represents the probability of obtaining the observed results of a statistical hypothesis test. The p-value is used as an alternative to rejection point to give the smallest level of significance at which the null hypothesis would be rejected. It can be used to test hypotheses in statistics.

If the p-value is less than the significance level (α), then the null hypothesis is rejected. However, if the p-value is greater than the significance level (α), then the null hypothesis is not rejected. Therefore, we reject the null hypothesis if the p-value is less than or equal to the level of significance.

So, if the p-value of the coefficient of an X variable in a regression is 0.001, it suggests that the coefficient is statistically significant and different from 0 in the population regression line. Hence, the statement "it is reasonable to say that the coefficient of the X variable is 0 in the population regression line" is false.
