The number of students surveyed who plays an instrument is 114 students.

The ratio of students who play instruments to those who do not is 7/20, which means that out of every 7+20=27 students, 7 of them play an instrument and 20 of them do not.

If we know that 440 students were surveyed, we can set up a proportion to find the number of students who play an instrument:

7/27 = x/440

To solve for x, we can cross-multiply:

7 * 440 = 27 * x

3080 = 27x

x = 114.07

Since we can't have a fraction of a student, we should round up to the nearest whole number, which means that approximately 114 students surveyed play an instrument.

Therefore, the required answer is 114.

The cost of the shirt, in dollars, after the 30% discount is $17.50.

What is discount?

A discount is a reduction in the price of a product or service that is offered by a seller to a buyer. Discounts can be offered for a variety of reasons, such as to attract customers, increase sales, or clear out inventory. Discounts can be expressed as a percentage or a fixed amount, and they can be applied at the time of purchase or deducted from an invoice or bill. Discounts are often used in sales promotions, marketing campaigns, and loyalty programs to incentivize customers to buy or use a product or service.

If a store is offering a 30% discount on shirts that cost $25 originally, then the discount amount is:

30% of $25 = 0.30 x $25 = $7.50

The discount amount is $7.50, so the new price of the shirt after the discount is:

$25 - $7.50 = $17.50

Therefore, the cost of the shirt, in dollars, after the 30% discount is $17.50.

If David already has 7/4 pounds of jelly beans, then 1.55 pounds of gummy bears can he buy.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

To determine the remaining amount of money available left to buy gummy bears, we have to find the amount of money already spent on jelly beans.

Amount of money spent on jelly beans;

= 7/4 × 3.90

= 6.825

Amount of money left for gummy bears ;

= 15-6.825

The length of AC using the laws of sines is 29.5 inches

We can use the law of sines to solve this problem.

The law of sines states that in any triangle ∆ABC:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the lengths of the sides opposite to the angles A, B, and C, respectively.

In this case, we know that m<A = 33°, m<C = 58°, and AB = 25 in.

We need to find AC, which is opposite to angle A.

Let's use the law of sines to solve for AC:

AC/sin(B) = AB/sin(C)

Where

B = 180 - 33 - 58

B = 89

So, we have

AC/sin(89°) = 25/sin(58°)

This gives

AC = 29.5 in. (rounded to the nearest tenth)

a. The dimensions that maximize the area of the pen are 33 meters by 100 meters.

b. The dimensions of each rectangular pen that minimize the amount of fence used are 10sqrt(2) meters by 10sqrt(2) meters.

a. To maximize the area of the rectangular pen, we need to find the dimensions that use up all 200 meters of fencing, except for the side that is against the barn. Let the length of the pen be x and the width be y. Then we have:

Perimeter of the pen = 2x + y = 200 - x (since one side is against the barn)

Simplifying this equation, we get:

3x + y = 200

Area of the pen = xy

Now we can express y in terms of x using the equation above:

y = 200 - 3x

Substituting this into the expression for area, we get:

A(x) = x(200 - 3x) = 200x - 3x^2

To maximize the area, we need to find the value of x that makes A(x) as large as possible. We can do this by taking the derivative of A(x) with respect to x and setting it equal to 0:

A'(x) = 200 - 6x

200 - 6x = 0

x = 33.33

Since we can't have a fractional length, we choose x = 33 meters (rounded to the nearest meter). Then y = 200 - 3x = 100 meters.

b. Let the dimensions of each rectangular pen be x and y. Then we have:

Area of each pen = xy = 100

Perimeter of each pen = 2x + 2y

We want to minimize the amount of fence used, which is equal to the total perimeter of all four pens. So, we need to find the dimensions that minimize the total perimeter subject to the constraint that the area of each pen is 100. We can use Lagrange multipliers to solve this problem:

L(x, y, λ) = 2x + 2y + λ(xy - 100)

Taking the partial derivatives with respect to x, y, and λ, we get:

∂L/∂x = 2 + λy = 0

∂L/∂y = 2 + λx = 0

∂L/∂λ = xy - 100 = 0

Solving these equations simultaneously, we get:

x = y = sqrt(200/λ)

xy = 100

Substituting the first equation into the second equation, we get:

sqrt(200/λ)^2 = 100

λ = 2

Substituting λ = 2 back into the first equation, we get:

x = y = sqrt(200/λ) = 10sqrt(2)

The probability of getting 1, 2, or 3 at the most 9 times after rolling a fair die 12 times is given by 0.9807.

Probability that 1, 2, or 3 is rolled at most 9 times,

Consider all the possible outcomes of rolling a fair die 12 times.

Count the number of outcomes where 1, 2, or 3 is rolled at most 9 times.

Use the complementary probability,

Probability that 1, 2, or 3 is rolled more than 9 times,

Then subtract that probability from 1 .

Let X be the number of times 1, 2, or 3 is rolled in 12 rolls.

Then X follows a binomial distribution with n=12 and p=1/2,

Since there are 3 favorable outcomes out of 6 possible outcomes on each roll.

The probability that 1, 2, or 3 is rolled more than 9 times can be calculated as follows,

P(X > 9) = P(X = 10) + P(X = 11) + P(X = 12)

= (¹²C₁₀) (1/2)^10 (1/2)^2 + (¹²C₁₁) (1/2)^11 (1/2)^1 + (¹²C₁₂) (1/2)^12 (1/2)^0

= 66/2^12 + 12/2^12 + 1/2^12

= 79/2^12

Probability that 1, 2, or 3 is rolled at most 9 times is,

P(X ≤ 9)

= 1 - P(X > 9)

= 1 - 79/2^12

= 4017/2^12

Rounding this to four decimal places gives,

P(X ≤ 9) ≈ 0.9807

Therefore, the probability that 1, 2, or 3 is rolled at most 9 times is approximately 0.9807.

The center of gravity is located 96.7 inches aft of the datum.

To determine the location of the center of gravity (CG) of the system, we need to calculate the moment of each weight about the datum, and then divide the sum of the moments by the total weight of the system.

The moment of each weight is equal to its weight multiplied by its distance from the datum. In this case:

Moment of weight a = 140 pounds x 17 inches = 2,380 inch-pounds

Moment of weight b = 120 pounds x 110 inches = 13,200 inch-pounds

Moment of weight c = 85 pounds x 210 inches = 17,850 inch-pounds

The total weight of the system is:

Total weight = weight a + weight b + weight c = 140 + 120 + 85 = 345 pounds

Therefore, the location of the CG can be calculated as follows:

CG location = (Moment of weight a + Moment of weight b + Moment of weight c) / Total weight

CG location = (2,380 + 13,200 + 17,850) / 345

CG location = 33,430 / 345

CG location = 96.7 inches aft of datum

As a result, the center of gravity is 96.7 inches aft of the datum.

The distance between A and B is approximately 8.06 units.

In order to find the distance, d, of AB, we need to use the distance formula. The distance formula gives us the distance between two points in a coordinate plane. It is given as:$$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$ where (x1, y1) and (x2, y2) are the coordinates of the two points in question.

In this case, A and B are the two points for which we need to find the distance. Let's assume that the coordinates of A are (x1, y1) and the coordinates of B are (x2, y2).

Then the distance formula becomes:

$$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$

$$d = \sqrt{((8 + 4) - 2)^2 + ((5 - 1) - 3)^2}$$

$$d = \sqrt{(10 - 2)^2 + (4 - 3)^2}$$

$$d = \sqrt{(8)^2 + (1)^2}$$

$$d = \sqrt{64 + 1}$$

$$d \approx \sqrt{65}$$

$$d \approx 8.06$$

Therefore, the distance between A and B is approximately 8.06 units.

The probability of selecting two marbles with the same color is approximately 0.27 or 27%.

To work out the likelihood that the two marbles drawn have similar variety, we can utilize the accompanying advances:

In the first place, we compute the likelihood of drawing a red marble on the principal pick: 12/24 = 1/2.

On the off chance that the main marble drawn is red, there will be 11 red marbles left clinched, out of a sum of 23 marbles. So the likelihood of drawing one more red marble on the subsequent pick is 11/23.

Likewise, in the event that the principal marble drawn is blue, there will be 4 blue marbles left clinched, out of a sum of 23 marbles. So the likelihood of drawing one more blue marble on the subsequent pick is 4/23.

Furthermore, on the off chance that the main marble drawn is yellow, there will be 6 yellow marbles left taken care of, out of a sum of 23 marbles. So the likelihood of drawing one more yellow marble on the subsequent pick is 6/23.

To get the complete likelihood of drawing two marbles of similar variety, we want to add the probabilities of every one of these cases:

(1/2) x (11/23) + (5/24) x (4/23) + (7/24) x (6/23) = 55/138 or roughly 0.398 or 39.8%.
