To determine which option gives a better chance of winning, we need to calculate the expected number of A's and B's in the 1,000 draws and compare it to the conditions for winning in each option.

Let's calculate the expected number of A's and B's:

Number of A's in "ARABIA": 3

Number of B's in "ARABIA": 1

Total number of letters in "ARABIA": 6

Probability of drawing an A: 3/6 = 1/2

Probability of drawing a B: 1/6

Expected number of A's in 1,000 draws: (1/2) * 1,000 = 500

Expected number of B's in 1,000 draws: (1/6) * 1,000 = 166.67

Now let's analyze the conditions for winning in each option:

Option A: You win a dollar if the number of A's among the draws is 10 or more above the expected number (500 + 10 = 510 or more).

Option B: You win a dollar if the number of B's among the draws is 10 or more above the expected number (166.67 + 10 = 176.67 or more).

Comparing the two options:

Option A requires having 510 or more A's out of the 1,000 draws.

Option B requires having 176.67 or more B's out of the 1,000 draws.

Since it is not possible to have a fraction of a letter, the number of B's will always be an integer. Therefore, it is impossible to reach the condition for winning in option B, as there can't be 176.67 B's.

Therefore, the correct answer is:

(i) Option A gives a better chance of winning than option B.

The given differential equation y dx = 2(x y) dy is homogeneous, which can be solved by using the substitution y = ux. This leads to a separable differential equation in x and u, which can be integrated to obtain a general solution in terms of u. Finally, substituting back to y = ux gives the general solution to the original differential equation.

The given differential equation y dx = 2(x y) dy is homogeneous, which means that it is possible to solve it by using a substitution of the form

y = ux.

This yields the following differential equation in x and u:

u dx + x du = 2u du.

We can simplify this equation by rearranging the terms:

(x - 2u) du + u dx = 0. This equation is separable, which means that we can separate the variables and integrate both sides to solve for u.

To do this, we divide both sides by (x - 2u) u, which gives:

(1/u) du / (x - 2u) = -dx / u. Integrating both sides yields:

-ln|x - 2u| = ln|u| + C, where C is a constant of integration.

Exponentiating both sides and solving for u gives:

u = ±(Cx) / sqrt(4x^2 + C^2).

Substituting y = ux gives the general solution to the original differential equation: y = ±(Cx^2) / sqrt(4x^2 + C^2).

Marianne's total candle sales for the week rounded to the nearest

cent is $6539.13.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

From the given information, Let Marianne's total sale be $'x'.

Therefore, $376 is 5.75% of 'x'. which can be numerically expressed as,

(5.75/100)×x = 376.

0.0575x = 376.

x = $6539.13

5) We have to find the winner using the Copeland method.

In this method we compare each pair of candidates and see which one is preferred.

The candidate that wins is awarded one point.

If it is a tie, each one gets 1/2 points.

In this case, we have to consider the number of votes per column.

Then, we will have 4!/(2! * 2!) = 24/4 = 6 pairs.

We compare each pair:

-AB:

For the first column: A

For the second column: B

For the third column: A

For the fourth column: B

For the fifth column: B

For the sixth column: A

Then, for A we have 7 + 11 + 12 = 30.

For B we have 10 + 6 + 6 = 22.

Then A earns one point.

For the next pairs we repeat the process:

-AC:

We will directly count the votes for each candidate.

Votes for A: 11 + 6 + 12 = 29.

Votes for C: 7 + 10 + 6 = 23.

Then A earns another point.

-AD:

Votes for A: 7 + 12 = 19

Votes for D: 10 + 11 + 6 + 6 = 33

Then D earns one point.

-BC:

Votes for B: 10 + 6 + 6 + 12 = 34

Votes for C: 7 + 11 = 18

Then B earns one point.

-BD:

Votes for B: 10 + 6 + 12 = 28

Votes for D: 7 + 11 + 6 = 24

Then B earns another point.

-CD:

Votes for C: 7 + 10 +6 + 12 = 35

Votes for D: 10 + 6 = 16

Then C earns a point.

The total points are:

A: 2 points

B: 2 points

C: 1 point

D: 1 point

We have a tie between A and B.

We don't have a rule that is applied to break the tie, but we can look at the pair AB to see which one wins in that case. If we look A > B, so we can consider A to be the winner after the tie.

6) We have to apply the plurality method.

In this case we only look at the first choices.

Then, from the first column, C gets 7 votes.

From the second column, B gets 10 votes.

From the third column, D gets 12 votes.

From the fourth column, B gets another 6 votes.

From the fifth column, D gets another 6 votes.

From the sixth columns, A gets 12 votes.

Then, we can summarize as:

A = 12

B = 10 + 6 = 16

C = 7

D = 12 + 6 = 18

Then, D is the winner according to the plurality method.

Answer:

5) The Copeland's method gives a tie between A and B. We can break the tie comparing the pair (A,B), where A wins over B.

6) The plurality method gives D as the winner.

The number of possible outcomes in the sample space of a wireless garage door opener with 16 switches can be determined using the concept of combination is 1.

Combination is a mathematical concept that refers to the number of ways that a set of objects can be selected from a larger set without regard to their order.

To determine the number of possible outcomes in the sample space, we can use the concept of combination. In this case, the objects are the 16 switches, and the larger set is the set of all possible settings for these switches (up or down).

To calculate the number of possible combinations, we can use the formula for combination, which is:

ⁿCₓ = n! / (x! * (n - x)!)

where n is the total number of objects (16 switches), and x is the number of objects selected (in this case, also 16 switches). The exclamation mark (!) represents the factorial function, which is the product of all positive integers up to and including the given integer.

Using this formula, we can calculate the number of possible combinations as follows:

=> 16! / (16! x (16 - 16)!)

=> 16! / (16! x 0!)

=> 1

Therefore, the sample space of possible codes for a wireless garage door opener with 16 switches is 1.

Step-by-step explanation:

The probability of selecting exactly one defective calculator out of the 6 sent to the local high school is 0.29166.

The probability of selecting exactly one defective calculator out of the 6 sent to the local high school can be calculated using the binomial probability formula. The binomial probability formula is \(P(x) = nCx * p^x * q^(n-x)\). For this problem, n = 6 (the number of calculators sent to the local high school), x = 1 (the number of defective calculators selected), p = 4/12 (the probability of selecting a defective calculator from the shipment of 12 calculators), and q = 8/12 (the probability of selecting a non-defective calculator from the shipment of 12 calculators). Plugging these values into the formula gives \(P(x) = 6C1 * 4/12^1 * 8/12^5\), which simplifies to 0.29166. This means that the probability of selecting exactly one defective calculator out of the 6 sent to the local high school is 0.29166.

The two percentages do not agree. Hence, option D is correct.

a) The mean time was 103.59 seconds, with a standard deviation of 5.16 seconds. If the Normal model is appropriate, the percentage of times that will be less than 98.43 seconds can be calculated as follows:

z = (x - μ) / σz = (98.43 - 103.59) / 5.16z = -1.00Using z-score table, we can determine that the percentage of times that will be less than 98.43 seconds is approximately 15%.

Therefore, the percentage of times that will be less than 98.43 seconds is 15%.

(Round to the nearest integer as needed)Hence, option A is correct.b) The actual percentage of times less than 98.43 seconds can be calculated by finding the number of competitors that finished with a time less than 98.43 seconds and dividing that number by the total number of competitors.

98.06, 98.09, 98.46, 98.47, 98.96, 98, 99, 99.12, 99.35, 99.57, 99.98, 100.08, 100.11, 100.28, 100.64, 101.32, 101.06, 101.25, 101.34, 101.39, 102.48,

There are no competitors who finished with a time less than 98.43 seconds. Therefore, the actual percentage of times less than 98.43 seconds is 0%. (Round to one decimal place as needed)Thus, option D is correct.c) The two percentages do agree.

This is because the Normal probability plot shows that the Normal model is not appropriate.

Therefore, the actual percentage of times less than 98.43 seconds is 0%, which is different from the percentage that was calculated using the Normal model. Since the Normal model is not appropriate, the actual percentage of times is more accurate.

Here we want to study the magnetic force due to a magnet, we will see that the correct option is D, move.

Magnets create a magnetic field around them, such that any object inside that field is affected due to that field (you can think that the magnet is submerged in this magnetic field that is in the space around it).

The magnetic field affects other magnetized objects (such as magnets) repulsing or attracting them, depending on the polarization (opposite polarizations attract and equal polarizations repel)

With that in mind, the property of the magnetic force is that it can move another magnet without touching them, thus the correct option is D, move.
