Answer:

D. The number of multiple-choice questions plus the number of

short-answer questions is 15.

The number of arrangements of the letters in mathematics such the last vowel in the arrangement is an i are 30,240.

To find the number of arrangements of the letters in "mathematics" such that the last vowel in the arrangement is an "i". Counting the vowels, we have three vowels that are a, e, and i.

Count the number of ways to arrange the three vowels in the word. This is a permutation problem, and we can use the formula for permutations of n objects taken r at a time, which is:

P(n, r) = n! / (n-r)!

So, putting the values,

P(3, 3) = 3! / (3-3)! = 3! / 0! = 6

There are 6 methods to arrange a, i and e in the word. Now, we have to arrange the consonants. There are 7 consonants in "mathematics", but we have already placed the last vowel as "i", so we only need to arrange the remaining 6 letters. This is again a permutation problem, and we can use the formula for permutations of n objects taken r at a time:

P(n, r) = n! / (n-r)!

Putting values,

P(7, 6) = 7! / (7-6)!

= 7! / 1!

= 5040

There are 5040 ways to arrange the remaining 6 letters in the word.

Finally, we can multiply the number of arrangements of the vowels and the number of arrangements of the remaining consonants to get the total number of arrangements that meet the given condition:

6 * 5040 = 30,240

Therefore, there are 30,240 arrangements of the letters in "mathematics" such that the last vowel in the arrangement is an "i".

Answer:

The candle burns at a rate of 1/4 inch per hour.

The probability of the match finishing in two sets is higher than the probability of the match finishing in three sets, so if you were to bet on the outcome, you would bet on it finishing in two sets.

P(win in 2 sets) = P(win 1st set) * P(win 2nd set)

P(win in 2 sets) = 0.5 * 0.5

P(win in 2 sets) = 0.25 or 25%

The probability of winning three sets in a best-of-three tennis match is:

P(win in 3 sets) = P(win 1st set) * P(lose 2nd set) * P(win 3rd set)

P(win in 3 sets) = 0.5 * 0.5 * 0.5

P(win in 3 sets) = 0.125 or 12.5%

As a result, the liability of the match ending in two sets is lesser than the probability of the match ending in three sets,  therefore if you were to  go on the  outgrowth, you would  go on the match ending in two sets. It's  pivotal to note,  still, that this presupposes a constant chance of winning a set, which may not be the case in practise.

The correct answer is C. 20 in. To calculate the area of the triangle, we can use the formula A = 1/2 bh. The base of the triangle is 10 in and the height is 8 in, so the area is 1/2 x 10 x 8 = 40 in^2. Since the triangle is a right triangle, the area is half of 40 in^2, which is 20 in^2

1. The cost for 100 shares at the 52-Week Low is $52.28 (option a).

2. The amount received if you sold your 100 shares at the High on August 16 is $67.20 (option d).

3. Your net gain or net loss after the sale of your 100 shares was $1492 Net Gain. (option d)

4. If you sold stock for $3200 and your broker earns 2% of that as his fee, Then the amount did the broker receive was $64. (option a).

To calculate the cost of 100 shares at the 52-Week Low, we need to multiply the low price per share by the number of shares. Therefore, the cost for 100 shares at the 52-Week Low can be calculated as follows:

Cost = 100 x 52-Week Low price per share

Out of the options given, the correct answer is A. $5228, assuming that the 52-Week Low price per share is $52.28.

To calculate the amount received from selling 100 shares at the High on August 16, we need to multiply the high price per share by the number of shares. Therefore, the amount received can be calculated as follows:

Amount Received = 100 x High price per share

Out of the options given, the correct answer is D. $6720, assuming that the high price per share on August 16 was $67.20.

To calculate the net gain or loss after the sale of 100 shares, we need to subtract the cost of buying the shares from the amount received from selling them. Therefore, the net gain/loss can be calculated as follows:

Net Gain/Loss = Amount Received - Cost

Using the numbers from the previous questions, we can calculate the net gain/loss as follows:

Net Gain/Loss = $6720 - $5228

Net Gain/Loss = $1492

Therefore, the correct answer is D. $1492 Net Gain.

To calculate the amount received by the broker as a fee for selling stock for $3200, we need to multiply the selling price by the broker's commission rate, which is given as 2%. Therefore, the broker's fee can be calculated as follows:

Broker's Fee = Selling Price x Commission Rate

Using the numbers from the question, we can calculate the broker's fee as follows:

Broker's Fee = $3200 x 0.02

Broker's Fee = $64

Therefore, the correct answer is A. $64.

If the interior angle's of the right-triangle are 60°, 90° and 30°, then length of side"A" is 9.24cm and side"B" is 8 cm.

In a "right-triangle", the "Sine" of an angle is defined as the length of the opposite side divided by the length of the hypotenuse,

The "Cosine" of an angle is defined as the length of the adjacent side divided by the length of the hypotenuse.

The hypotenuse (opposite the right angle) is "A".

The base (adjacent to the 60° angle) is "B".

The height (opposite the 60° angle) is given as 8 cm.

Using the 60° angle and height, we can find the length of the base :

⇒ Sin(60°) = (opposite-side)/(hypotenuse),

⇒ Sin(60°) = 8/A,

⇒ A = 8/Sin(60°),

⇒ A ≈ 9.24 cm

Using the 30° angle and base, we can find the length of the height as:

⇒ Cos(30°) = (adjacent-side)/(hypotenuse),

⇒ Cos(30°) = B/A,

⇒ B = A × Cos(30°),

⇒ B = 9.24 × Cos(30°),

⇒ B ≈ 8.00 cm

The value of x and y can be found using the Pythagorean Theorem and the law of sines;

x = 3·√(17)

y ≈ 7.37

The Pythagorean Theorem states that the square of the length of the longest side of a right triangle (the hypotenuse side) is equivalent to the sum of the squares of the other two sides of the right triangle

The value of y can be obtained from the law of sines as follows;

5/(sin(36°)) = y/(sin(60))

y = (sin(60)) × 5/(sin(36°))

(sin(36°)) = √((10 - 2·√5))/4

(sin(60)) = √(3)/2

y = (sin(60)) × 5/(sin(36°)) = √(3)/2 × 5 × 4/√((10 - 2·√5)) = 10·√(3)/√((10 - 2·√5)) ≈ 7.37

There is a 97.91% chance that at least 74 students out of 130 randomly selected students would prefer a boy.

To find the probability that at least 74 students would prefer a boy out of 130 randomly selected students, we need to use the binomial probability formula:

P(X >= k) = 1 - P(X < k)

Where:

P(X >= k) is the probability that the number of students who prefer a boy is greater than or equal to k

P(X < k) is the probability that the number of students who prefer a boy is less than k

In this case, k = 74, n = 130, and the probability of success (i.e., preferring a boy) is p = 0.45 (based on the results of the poll).

To calculate P(X < 74), we can use a binomial distribution calculator or a statistical software program. The result is 0.0209.

Therefore, the probability that at least 74 students would prefer a boy is:

P(X >= 74) = 1 - P(X < 74)

P(X >= 74) = 1 - 0.0209

P(X >= 74) = 0.9791

Answer:

The ratio of green apples to red apples is 6:7.

Step-by-step explanation:

The ratio of all apples in the basket to red apples is 13:7 (since there are 13 total apples and 6 of them are green, leaving 13-6=7 red apples).

The value of both variables is equal to 23.

The angle measures are 45 degrees and 135 degrees respectively.

In Mathematics and Geometry, a supplementary angle simply refers to two (2) angles or arc whose sum is equal to 180 degrees.

Additionally, the sum of all of the angles on a straight line is always equal to 180 degrees. In this scenario, we can reasonably infer and logically deduce that the sum of the given angles are supplementary angles:

(2x - 1)° + (4x + 43)° = 180°

By rearranging and collecting like-terms, the value of y is given by:

6x + 42 = 180

6x = 180 - 42

x = 138/6 = 23

(2x - 1)° = 2(23) - 1 = 45°

(4x + 43)° = 4(23) + 43 = 135

To evaluate P(2), we plug in n=2 into the inequality 2^n < (n+1)!. This gives us 2^2 < (2+1)! which simplifies to 4 < 6. Therefore, P(2) is true.

To show the inductive step for k≥2, we assume that P(k) is true, i.e. 2^k < (k+1)!. We need to show that P(k+1) is also true, i.e. 2^(k+1) < (k+2)!.

Starting with P(k), we can multiply both sides by 2 to get 2^(k+1) < 2(k+1)!. Now we just need to show that 2(k+1)! < (k+2)!, which simplifies to 2 < (k+2)/(k+1). This is true for all k≥1, so P(k+1) is also true.

Therefore, we have shown that if P(k) is true for some integer k≥2, then P(k+1) is also true. This completes the inductive step.
(a) P(2) is given by the inequality 2^(n+1) < (n+1)!. When n = 2, the inequality becomes 2^(2+1) < (2+1)!, which simplifies to 2^3 < 3!, or 8 < 6. This is not true, so P(2) is false.

(b) P(k) is the inequality 2^(k+1) < (k+1)!. In the inductive step, we need to show that if k is any integer with k ≥ 2 and if P(k) is true, then P(k+1) is also true. This means that if 2^(k+1) < (k+1)!, we need to show that 2^(k+2) < (k+2)!.

A machine learning model overfits when it becomes overly complicated and begins to memorize the training data rather than learning broad patterns that can be applied to fresh data. In other words, the model performs worse on the validation or test set because it cannot generalize to new data due to how well it fits the training data.

Assume, for instance, that we train a convolutional neural network (CNN) on the 2,000 training images in the cats vs. dogs dataset and obtain high accuracy on the training set. However, the accuracy drastically declines when we test the model on the 2,000 test photographs. This is a symptom of overfitting and indicates that the model cannot generalize to new data since it has learned the specific features of the training set too well. We can employ strategies like regularisation, dropout, and early halting, as well as increasing the volume of training data, to avoid overfitting.

The best point estimate for the mean monthly car payment for all residents of the local apartment complex is 631

The best point estimate for the mean monthly car payment for all residents of the local apartment complex is simply the sample mean, which is $631. This is because the sample mean is an unbiased estimator of the population mean, meaning that on average, it will give us an accurate estimate of the true population mean.

To explain this in mathematical terms, let's use X to represent the monthly car payment for an individual resident of the apartment complex. We have a sample of n=97 residents, and we can calculate the sample mean as follows:

[tex]$\bar{X} = \frac{1}{n} \sum_{i=1}^{n} X_i$[/tex]
