The probability that you are right is 0%.

Alice draws a 2-card hand from a standard 52-card deck, which means there are only four aces in the deck. On the other hand, Bob rolls two dice, each with six sides, so there are only two ways to roll two aces: rolling a double 1 or rolling a double 6. These events are much less likely compared to Alice drawing two aces from the deck.

Given that the game show host tells you that the mystery person obtained two aces, the only possible explanation is that it must be Alice. Bob simply does not have a high enough probability of rolling two aces to be considered as the mystery person in this scenario.

In summary, because Bob's chances of rolling two aces are significantly lower than Alice's chances of drawing two aces, the probability of you being right by guessing Bob is 0%.

Step-by-step explanation: 0.33 as a percent is 33% and 2/5 as a percent is 40% and 40 is the most the 40% wins

The coefficient of variation for set A is approximately 2.3% and for set B is approximately 24.8%.

The coefficient of variation (CV) is a statistical measure that represents the relative variability of a dataset compared to its mean. It is calculated by dividing the standard deviation of the dataset by the mean and multiplying the result by 100 to express it as a percentage.

For set A:

1. Calculate the mean: (21,851 + 20,126 + 21,283 + 21,675 + 21,987 + 21,046 + 22,014 + 21,086 + 21,822 + 21,010 + 21,991 + 22,118 + 21,010 + 21,773) / 14 = 21,482.4

2. Calculate the standard deviation: sqrt(((21,851-21,482.4)^2 + (20,126-21,482.4)^2 + ... + (21,773-21,482.4)^2) / 13) = 502.1

3. Calculate the CV: (502.1 / 21,482.4) * 100 ≈ 2.3%

For set B:

1. Calculate the mean: (2.6 + 3.5 + 4.6 + 3.2 + 2.0 + 2.6 + 4.9 + 3.3 + 3.7 + 2.7 + 4.3) / 11 = 3.41

2. Calculate the standard deviation: sqrt(((2.6-3.41)^2 + (3.5-3.41)^2 + ... + (4.3-3.41)^2) / 10) = 0.846

3. Calculate the CV: (0.846 / 3.41) * 100 ≈ 24.8%

Therefore, the coefficient of variation for set A is approximately 2.3% and for set B is approximately 24.8%.

Note: Coefficient of variation is a useful measure to compare the relative variability between datasets. A lower CV indicates lower relative variability, while a higher CV indicates higher relative variability.

In this case, set A has a lower CV, indicating less variability compared to its mean, whereas set B has a higher CV, indicating higher variability compared to its mean.

The system of inequalities which is represented as described in the task content is;

As evident in the task content; the first graph is a solid line increasing from left to right passing through 0 comma negative 3 and 3 comma 0. Hence, the slope of the line is positive and the y-intercept is -3.

Since the region below the line is shaded; the inequality is; y ≤ x - 3.

Also, second is a upward dashed parabola with a vertex at negative 3 comma negative 16 and x-intercepts at negative 1 comma 0 and 7 comma 0. The parabola equation is; y = x² - 6x - 7.

By using the given graph, we will see that:

Here we have a graph of function G(x), and we want to evaluate it in different values of x.

To do that, we need to look at the interval where the lines are defined. An open dot means that the endpoint does not belong to the interval, while the closed dot means that the endpoint belongs.

First, G(0).

If you look at the graph, when x = 0 we have a closed dot on the bottom line. That is the line that we need to look to do this evaluation, there we can see that when x = 0, we have G(0) = -5.

Then we have x = 2.999.

Notice that x < 3.

And the second line (the one at y = -3) is on the interval (0, 3].

Then x = 2.999 is included on that interval, it means that:

G(2.999) = -3.

Now we have x = 0.0001

Again, notice that the second line is on the interval (0, 3]

Because 3 > 0.0001 > 0, then:

0.0001 ∈ (0, 3]

From that, we conclude that:

G(0.0001) = -3

Finally:

G(3).

Again, 3 belongs to the interval (0, 3]

Then we use the second line again.

G(3) = -3

Step-by-step explanation:

If two events, event A with probability P(A) and event b with probability P(B) are complementary events then the sum of the probability of events A and B will be one.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

When one event happens if and only if the other one doesn't, two occurrences are said to be complimentary. The odds of two complementary events equal one.

P(A) + P'(A) = 1

The chance of events A and B added together will equal one if events A with probability P(A) and event B with probability P(B) are complementary occurrences.

The point of diminishing returns is (20.98, 21247.3).

The point of diminishing returns occurs when the marginal cost of producing an extra unit of output exceeds the marginal revenue generated from selling that unit. Mathematically, it is the point at which the derivative of the production function equals zero and the second derivative is negative.

Given the polynomial function N(x) of degree 3, we can find the point of diminishing returns by finding the critical points where the first derivative equals zero and evaluating the second derivative at those points.

The derivative of N(x) is N'(x) = -18x² + 360x + 2250. To find the critical points, we set N'(x) = 0:

0 = -18x² + 360x + 2250

Dividing by -18 simplifies the equation:

0 = x² - 20x - 125

Using the quadratic formula, we find the solutions to the equation:

x₁,₂ = (20 ± √(20² - 4(1)(-125))) / 2(1)

x₁,₂ = 10 ± 5√5

Thus, the two critical points of N(x) are at x = 10 - 5√5 and x = 10 + 5√5.

To determine the point of diminishing returns, we evaluate the second derivative N''(x) = -36x + 360 at these critical points:

N''(10 - 5√5) = -36(10 - 5√5) + 360 ≈ -264.8

N''(10 + 5√5) = -36(10 + 5√5) + 360 ≈ 144.8

From the evaluations, we find that N''(10 + 5√5) is negative while N''(10 - 5√5) is positive. Therefore, the point of diminishing returns corresponds to x = 10 + 5√5.

To find the corresponding y-coordinate (N(10 + 5√5)), we can substitute the value of x into the original function N(x).

Hence, the point of diminishing returns is approximately (20.98, 21247.3).

Sell $500,000 worth of real estate in order to earn a commission of $35,000 at a rate of 7%. So the correct answer is D) $500,000.

Use the given information to set up a proportion and solve for the unknown sales amount:

Commission earned / Sales amount = Commission rate

$21,000 / $300,000 = 0.07

Now we can use this proportion to find the sales amount needed to earn $35,000:

$35,000 / 0.07 = $500,000
