The number and the kind of roots of the equation, f(x) = x³ - x² - x + 1, is: D. 3 complex roots.

To determine the number and kind of roots of the equation f(x) = x³ - x² - x + 1, we can analyze the discriminant of the equation.

The discriminant, denoted as Δ, is given by:

Δ = b² - 4ac

In this case, the equation is in the form ax³ + bx² + cx + d = 0, where a = 1, b = -1, c = -1, and d = 1.

Calculating the discriminant:

Δ = (-1)² - 4(1)(-1)(-1) = 1 - 4(1)(1) = 1 - 4 = -3

The discriminant is negative (Δ < 0). This means that there are no real roots for the equation f(x) = x³ - x² - x + 1.

Therefore, the answer is:

D. 3 complex roots

So you use 73.02 minutes of talk time each month.

Cell phone is a portable electronic device that allows you to make calls, send messages, and perform various tasks such as browsing the internet.

Let x be the number of minutes of talk time you use each month.

The cost for the talk time each month is 19.80 + 0.09(x - 500), and the cost for e-mail is 0.2 * 19.80 = 3.96.

So, the total cost each month is 19.80 + 0.09(x - 500) + 3.96 = 23.76 + 0.09x - 46.04.

The total cost for 7 months is 7 * (23.76 + 0.09x - 46.04) = 166.32 + 0.63x.

We want to find the value of x that makes the total cost equal to $212.31, so we write:

166.32 + 0.63x = 212.31

Solving for x, we have:

0.63x = 45.99

x = 73.02

So you use 73.02 minutes of talk time each month

The margin of error on the survey is 0.882 (without the ± sign).

Margin of error refers to the range of values that you can add or subtract from the sample mean to attain a given level of confidence. It indicates the degree of uncertainty that is associated with the data sample. Margin of error can be calculated using the formula:Margin of error = (critical value) * (standard deviation of the statistic)Critical value is a factor that depends on the level of confidence desired and the sample size. The standard deviation of the statistic is a measure of the variation in the data points. Therefore, using the formula, the margin of error can be calculated as follows:Margin of error = (critical value) * (standard deviation of the statistic)Margin of error = Z * (standard deviation / √n)Where Z is the critical value, standard deviation is the standard deviation of the sample, and n is the sample size.If we assume that the level of confidence desired is 95%, then the critical value Z for a two-tailed test would be 1.96. Therefore:Margin of error = Z * (standard deviation / √n)Margin of error = 1.96 * ((172 - 154) / 2) / √nMargin of error = 1.96 * (9 / 2) / √nMargin of error = 8.82 / √nThe margin of error, therefore, depends on the sample size. If we assume a sample size of 100, then:Margin of error = 8.82 / √100Margin of error = 0.882

It will take Vincent 24 number of days to build the cubby house by himself.

Let's assume that Vincent can build the cubby house alone in h days.

From the given information, we know that Nadia takes 12 days to build the cubby house, and when Nadia and Vincent work together, they can finish it in 8 days.

We can use the concept of "work done" to solve this problem. The amount of work done is inversely proportional to the number of days taken.

Nadia's work rate is 1/12 of the cubby house per day, while the combined work rate of Nadia and Vincent is 1/8 of the cubby house per day.

When Nadia and Vincent work together, their combined work rate is the sum of their individual work rates:

1/8 = 1/12 + 1/h

To solve for h, we can rearrange the equation:

1/h = 1/8 - 1/12

1/h = (3 - 2) / 24

1/h = 1/24

Taking the reciprocal of both sides, we find:

h = 24

Therefore, the probability that a student participates in both student council and sports is 0.47 or 47%.

To find the probability that a student participates in both student council and sports, we need to use the concept of overlapping events and the formula for the probability of the intersection of two events.

Let's denote:

A = Event of participating in student council

B = Event of participating in sports

We are given the following information:

P(A) = 27% = 0.27

P(B) = 56% = 0.56

P(A or B) = 35% = 0.35

The probability of the intersection of two events can be calculated using the formula:

P(A and B) = P(A) + P(B) - P(A or B)

Substituting the given values:

P(A and B) = 0.27 + 0.56 - 0.35

P(A and B) = 0.82 - 0.35

P(A and B) = 0.47

The correct statement regarding the volumes is given as follows:

B. The volume of half the sphere is 2/3 the volume of the cylinder.

The volume of a cylinder of radius r and height h is given by the equation presented as follows:

V = πr²h.

The volume of a sphere of radius r is given by the equation presented as follows:

V = 4πr³/3

The diameter is twice the radius, however they have the same unit, hence we can keep using the radius for the formulas.

If the diameter and the radius of the cylinder are equal to the height, the volume is given as follows:

V = πr² x r = πr³.

Hence the volume of the sphere is of 4/3 the volume of the cylinder, hence the volume of half the sphere is 2/3 the volume of the cylinder, meaning that option B is correct.

Note that the area and perimeter of the shape with the above given coordinates are:

Area: 70 square units
Perimeter: 34 units.

To find the area and perimeter of the rectangle with the given vertices, we can use the distance formula to find the length and width of the rectangle, and then use these values to calculate the area and perimeter.

First, let's label the vertices of the rectangle as follows:

A = (-3, 3)

B = (-3, -7)

C = (4, -7)

D = (4, 3)

To find the length of the rectangle, we can use the distance formula to find the distance between points A and B (which are on the same vertical line) and between points C and D (which are also on the same vertical line):

AB = |3 - (-7)| = 10

CD = |3 - (-7)| = 10

So the length of the rectangle is 10.

To find the width of the rectangle, we can use the distance formula to find the distance between points A and D (which are on the same horizontal line) and between points B and C (which are also on the same horizontal line):

AD = |4 - (-3)| = 7

BC = |4 - (-3)| = 7

So the width of the rectangle is 7.

Therefore, the area of the rectangle is:

A = length x width = 10 x 7 = 70

And the perimeter of the rectangle is:

P = 2(length + width) = 2(10 + 7) = 34

So the area of the rectangle is 70 square units and the perimeter of the rectangle is 34 units. See the attached graph.

Two or more equations using the same variable are referred to mathematically as a "system of linear equations." These equations' solutions serve as a representation of the intersection of the lines.

Two equations are presented here:

1) x + 3y = 7

2) 2x + 4y = 8

First, in the first equation, we want to isolate x:

x + 3y = 7

x = 7 -3y

In order to create an equation that depends just on the variable y, we must now b) swap it out in the second equation.

2x + 4y = 8

2(7 - 3y) + 4y = 8

The value of y is now determined by solving this equation in step (c).

14 - 6y + 4y = 8

14 - 2y = 8

-2y = 8 - 14 = -6

y= 6/2= 3

d) With the value of y now available, we can change the equation we obtained in step a) by substituting it.

The first paragraph explains how slot machines and cell phones can create a sense of excitement and false hope, leading to addictive behaviors. It highlights the manipulation by app designers and the negative impact on interpersonal relationships. The second paragraph asks for an example of the Gambler's Fallacy.

The answer to the question is option B: "The slot machine didn't give me a winning amount for over an hour, so chances now are going to be that I hit the jackpot soon." This statement reflects the Gambler's Fallacy, which is the belief that previous outcomes will influence future outcomes in a game of chance.

The statement "As long as N is significantly less than K, logistic growth is indistinguishable from exponential" is false. If dN/dt > 0, then N increases.

The statement "As long as N is significantly less than K, logistic growth is indistinguishable from exponential" is false. Logistic growth takes into account the carrying capacity of the environment, represented by K, which limits the growth of a population as it approaches this limit. In contrast, exponential growth assumes an unlimited supply of resources and no constraints on population growth. Therefore, as N approaches K, logistic growth begins to level off, while exponential growth continues to increase indefinitely.
If dN/dt > 0, then N increases. This means that the population size is growing at a positive rate. If dN/dt is equal to zero, then N remains stable, indicating that the population size is not changing. Finally, if dN/dt is negative, then N decreases, indicating that the population size is shrinking. Therefore, the correct answer to this question is "increases."
