If Walmart is excluded from the list, the measure of center that would be more affected is the mean. The median, on the other hand, is less affected by extreme values, as it represents the middle value in the dataset.

If Walmart is excluded from the list, the measure of center that would be more affected is the mean. This is because Walmart is a large retailer and has a significant impact on the overall average of the data. Removing Walmart from the list would decrease the total sales and therefore decrease the mean. The median, on the other hand, would be less affected by the exclusion of Walmart as it only looks at the middle value of the data and is less sensitive to extreme values. The measure of center that would be more affected is the mean. Value like Walmart's revenue would significantly change the average. The median is less affected by extreme values, as it represents the middle value in the dataset.

Answer:

Step-by-step explanation:

Mode is the one that occurs the most.

Stem is first number repeated for leaf

so your list of numbers is

The one that occurs the most is 12.  So your mode is 12.

If there are multiple numbers that are "most" then there is no mode.

The absolute maximum value of f(x) over the interval [-3, 2] is approximately 5.24 and it occurs at x = 2, and the absolute minimum value is 1/8 and it occurs at x = 1/2.

To find the absolute maximum and minimum values of the function:

[tex]f(x) = (x^2-x)^{(2/3)}[/tex] over the interval [-3, 2], we need to follow these steps:

Find the critical points of the function by solving f'(x) = 0:

[tex]f'(x) = (2x - 1)\times{2/3}\times (x^2 - x)^{(-1/3)} = 0[/tex]

Solving for 2x - 1 = 0, we get x = 1/2. This is the only critical point in the interval [-3, 2].

Evaluate the function at the endpoints and the critical point:

f(-3) = ∛36 ≈ 3.301

f(2) = ∛12² ≈ 5.24

f(1/2) = 1/8

Determine which value is the absolute maximum and which is the absolute minimum:

The absolute maximum value is f(2) ≈ 5.24, and it occurs at x = 2.

The absolute minimum value is f(1/2) = 1/8, and it occurs at x = 1/2.

The 95% confidence interval estimate of the population mean μ is 97.53 < μ < 112.47.

We are required to find the 95% confidence interval estimate of the population mean μ, given the sample size n=18, mean x =105, and standard deviation s=15.

1. Determine the t-score for a 95% confidence interval with n-1 degrees of freedom. For a sample size of 18, you have 17 degrees of freedom.

Using a t-table or calculator, you find the t-score to be approximately 2.11.

2. Calculate the margin of error (E) using the formula:

E = t-score × (s / √n)

E = 2.11 × (15 / √18)

E ≈ 7.47

3. Calculate the lower and upper bounds of the confidence interval using the sample mean (x) and margin of error (E):

Lower bound: x - E = 105 - 7.47 = 97.53

Upper bound: x + E = 105 + 7.47 = 112.47

So, the 95% confidence interval estimate is 97.53 < μ < 112.47. Please note that these values are rounded to two decimal places.

The Prime factors of 18 are (2²) * 3 or 2 * 2 * 3. Thus, option B is the correct answer.

Prime numbers are numbers that are not divisible by any other number other than 1 and the number itself.

Composite numbers are numbers that have more than 2 factors that are except 1 and the number itself.

Prime factors are the prime numbers that when multiplied get the original number.

To calculate the prime factor, we use the division method.

In this method, firstly we divide the number by the smallest prime number it is when divided it leaves no remainder. In this case, we divide 18 by 2 and get 9.

Again, divide the number we get that, in this case, is 9, in the previous step by the prime number it is divisible by. So, 9 is again divided by 3 and we get 3.

We have to perform the previous step until we get 1. And 3 ÷ 3 = 3. Since we get 1, we stop here.

The solution to the difference equation Yt+1 + 3y = 16; Yo = 100,t 20.

Hence, the correct option is A.

To solve the difference equation Yt+1 + 3Yt = 16, with initial condition Y0 = 100 and t ≥ 0, we can first find the homogeneous solution, which is

Yh(t) = [tex]A(-1/3)^t[/tex]

Where A is a constant determined by the initial condition. Put in the initial condition Y0 = 100, we get

Yh(0) = A = 100

Therefore, the homogeneous solution is

Yh(t) = [tex]100(-1/3)^t[/tex]

Next, we find the particular solution by assuming a constant value for Yt+1 and Yt, which gives us

Yp(t) = 4

This is because we have

Yt+1 + 3Yt = 16

Yp(t+1) + 3Yp(t) = 16

4 + 3Yp(t) = 16

Yp(t) = 4

So the particular solution is

Yp(t) = 4

Finally, the general solution is the sum of the homogeneous and particular solution

Y(t) = Yh(t) + Yp(t) = [tex]100(-1/3)^t[/tex] + 4

Using the initial condition Y20 = 100, we can solve for the constant A

Y20 = [tex]100(-1/3)^20 + 4 = A(-1/3)^20 + 4[/tex]

100 = [tex]A(-1/3)^20 + 4[/tex]

A = 96

Therefore, the solution to the difference equation Yt+1 + 3Yt = 16 with initial condition Y0 = 100 and t ≥ 0 is

Y(t) = [tex]96(-1/3)^t + 4[/tex]

Yt = [tex]96(-3)^t + 4[/tex]

We can use the double angle formula for cosine, which is: cos(2x) = 1 - 2*sin^2(x) First, we square sin(x): sin^2(x) = (3/4)^2 = 9/16 Now, substitute this value into the double angle formula: cos(2x) = 1 - 2*(9/16) = 1 - 18/16 = -2/16 So, cos(2x) = -1/8.

To compute Cos(2x), we can use the double angle formula which states that Cos(2x) = 2Cos^2(x) - 1.

Now, we are given that sin(x) = 3/4. Using the Pythagorean identity sin^2(x) + Cos^2(x) = 1, we can solve for Cos(x):

sin^2(x) + Cos^2(x) = 1

3/4^2 + Cos^2(x) = 1

9/16 + Cos^2(x) = 1

Cos^2(x) = 7/16

Cos(x) = ±√(7/16)

Since we know that x is in the first quadrant (sin is positive and Cos is positive), we can take the positive square root:

Cos(x) = √(7/16) = √7/4

Now we can plug this value of Cos(x) into the double angle formula:

Cos(2x) = 2Cos^2(x) - 1

Cos(2x) = 2(√7/4)^2 - 1

Cos(2x) = 2(7/16) - 1

Cos(2x) = 7/8 - 1

Cos(2x) = -1/8

By using the L'Hospital's Rule, we have shown that the limit of x^(3/x) as x approaches infinity is equal to 1.

To find the limit of the function [tex]x^{3/x}[/tex] as x approaches infinity, we can use L'Hopital's Rule, which states that if we have an indeterminate form of a fraction such as 0/0 or infinity/infinity, we can take the derivative of the numerator and the denominator separately until we no longer have an indeterminate form.

First, we can rewrite the function as e^(ln([tex]x^{3/x}[/tex])). Then, we can use the properties of logarithms to simplify it further as e^((3ln(x))/x). Now, we have an indeterminate form of infinity/infinity, and we can apply L'Hopital's Rule.

Taking the derivative of the numerator and denominator, we get:

lim x→∞ [tex]x^{3/x}[/tex] = lim x→∞ e^((3ln(x))/x)

= e^(lim x→∞ (3ln(x))/x)

Using L'Hopital's Rule on the exponent, we get:

= e^(lim x→∞ (3/x²))

Since the denominator is approaching infinity faster than the numerator, the limit of 3/x² as x approaches infinity is zero, and we are left with:

= e^(0)

= 1

Therefore, the limit of [tex]x^{3/x}[/tex] as x approaches infinity is 1.

Alternatively, we can use some algebraic manipulation and the squeeze theorem to find the limit without using L'Hopital's Rule. We can rewrite the function as [tex]x^{3/x}[/tex] = (x^(1/x))³, and notice that as x approaches infinity, 1/x approaches zero, and so x^(1/x) approaches 1 (as the exponential function with base e^(1/x) approaches 1). Therefore, we have:

To show that the amount of glucose A(t) in the bloodstream at any time t is governed by the given differential equation, we need to consider the rates of glucose infusion and removal.

1. Glucose is infused into the bloodstream at a constant rate of C g/min. This means the rate of glucose infusion is simply C.

2. The glucose is converted and removed from the bloodstream at a rate proportional to the amount of glucose present. We can represent this by the equation: removal rate = kA, where k is a constant and A is the amount of glucose at time t.

Now, we can write the differential equation for A(t) by considering the net rate of change of glucose in the bloodstream. The net rate is the difference between the infusion rate and the removal rate:

A'(t) = infusion rate - removal rate

Substitute the values for the infusion rate and removal rate from the steps above:

A'(t) = C - kA

The amount of glucose A(t) in the bloodstream at any time t is governed by the differential equation A'(t) = C - kA, where C is the constant rate of glucose infusion, and k is the constant proportionality factor for glucose removal.

(a) To determine if the sequence converges or diverges, we can use the limit comparison test. We compare the given sequence to a known sequence whose convergence/divergence we know. Let bn = 5n^2/n^3 = 5/n. Then, taking the limit as n approaches infinity of (an/bn), we get:

lim (an/bn) = lim [(3 + (5n^2)/tn^(3/n) + 2)/(5/n)]
= lim [(3n^(3/n) + 5n^2)/5]

Since the limit is infinity, the sequence diverges.

(b) bn = 1/n. This is a p-series with p = 1, which diverges. Therefore, the given sequence also diverges.

(c) An = cos(n) + 1. The cosine function oscillates between -1 and 1, so the sequence oscillates between 0 and 2. However, since there is no limit to the oscillation, the sequence diverges.

(d) b) bn = e^(2n)/(n+2). To determine if this sequence converges or diverges, we can use the ratio test. Taking the limit as n approaches infinity of (bn+1/bn), we get:

lim (bn+1/bn) = lim (e^(2(n+1))/(n+3)) * (n+2)/e^(2n)
= lim (e^2/(n+3)) * (n+2)
= 0

Since the limit is less than 1, the sequence converges. To find the limit, we can use L'Hopital's rule to evaluate the limit of (e^(2n)/(n+2)) as n approaches infinity:

k = 1400 + 2300 + 380 + 420 = 820

n = 2200 + 400 + 300 + 80 + 20 = 3000

To determine the dispersion parameter β, we can use the method of

moments. For a negative binomial distribution, the mean and variance

are given by:

mean = θ

variance = θ(1 + βθ)

Solving for θ and β, we get:

θ = variance/mean

β = (variance/mean) - 1

Using the data from Year 1, we can estimate the mean and variance of the number of claims as follows:

mean = k/n = 820/3000 = 0.2733

[tex]variance = \sum (x - mean)^2 / n = 02200 + 1400 + 2300 + 380 + 4\times 20 / 3000 = 0.6313[/tex]

Substituting these values into the equations above, we get:

θ = 0.6313/0.2733 = 2.3104

β = (0.6313/0.2733) - 1 = 1.3088

Finally, we can use the credibility formula to calculate the credibility factor, Z, for Year 2:

Z = (k + nβ)/(n + β) = (0 + 3000*1.3088)/(3000 + 1.3088) = 1.2875

Therefore, the credibility factor, Z, for Year 2 is 1.2875. This means that we should give more weight to the expected number of claims for Year 2 based on the data from Year 1, rather than the expected number of claims based on the conditional negative binomial distribution with β=0.5.

The higher the credibility factor, the more weight we should give to the observed data from Year 1, and the less weight we should give to the prior distribution.

1) We are 90% confident that the average boot time of all computers with an SSD is greater than the average of all computers with an HDD.

Option 5) We are 90% confident that the difference between the two sample means falls within the interval. This means that we can say with 90% confidence that the true difference in average boot times between computers with SSDs and HDDs is somewhere between 4.2 and 13 seconds. We cannot make any conclusions about which type of drive has a faster boot time or whether there is a significant difference between them without further analysis or information.

When a₁ = 4, d = 3.5, and n = 14 are given.The value of A(14) is 49.5, the correct answer is option C. The issue appears to be related to number juggling arrangements, where A(n) speaks to the nth term of the arrangement and a₁ speaks to the primary term of the sequence.

Ready to utilize the equation for the nth term of a math grouping:

A(n) = a₁ + (n-1)d

where d is the common contrast between sequential terms.

A(14) = 4 + (14-1)3.5

Streamlining this condition, we get:

A(14) = 4 + 13*3.5

A(14) = 4 + 45.5

A(14) = 49.5

Hence, the esteem of A(14) is 49.5, which is choice C.

The standard deviation of the average drying times is 2.5 minutes.

To find the standard deviation of the average drying times for a sample of 36 paint drying times, we'll use the formula: Standard deviation of the sample mean = Population standard deviation / √(sample size).

In this case, the paint drying times are normally distributed with a mean of 120 minutes and a standard deviation of 15 minutes.

The sample size is 36. Standard deviation of the sample mean = 15 / √(36) = 15 / 6 = 2.5 minutes. So, the standard deviation of the average drying times for the sample is 2.5 minutes.

Expressing the regression equation in terms of the x variable instead of the y variable will cause the y-intercept and slope to change.

When the regression equation is expressed in terms of the y variable, it takes the form of: [tex]u=ax+b[/tex]                                where a is the y-intercept (the value of y when x = 0) and b is the slope (the rate at which y changes with respect to x).

If we express the same regression equation in terms of the x variable, it becomes:

[tex]x=\frac{y-a}{b}[/tex]

In this form, the y-intercept becomes [tex](0,\frac{a}{b} )[/tex], which is a point on the x-axis, and the slope becomes [tex]\frac{1}{b}[/tex] , which is the reciprocal of the slope in the original equation.

Therefore, expressing the regression equation in terms of the x variable instead of the y variable will cause the y-intercept and slope to change
