The shark is fed during the feeding at night is 1/6 tons.

What is a proper fraction?

A proper fraction is one that doesn't contain any whole numbers and has a smaller numerator than a denominator. A fraction that represents a number greater than one and has a larger numerator than the denominator is said to be improper.

Given that during the morning feeding, 2/15 of a ton of fish is fed. During the afternoon feeding the weight of the fish fed will be 1/15 of a ton more than the fish fed during the morning.

The shark fed (2/15 + 1/15) ton during the afternoon.

Assume that the shark fed x tons at night.

Therefore, the total fed is 2/15 + (2/15 + 1/15) + x

The equation is:

2/15 + (2/15 + 1/15) + x = 1/2

Add like terms:

5/15 + x = 1/2

1/3 + x = 1/2

Subtract 1/3 from both sides:

x = 1/2 - 1/3

x = (3-2)/6

x = 1/6

Therefore, the probability that the average amount of lead in 50 batches is greater than 6.5 mg is approximately 0.038 or 3.8%.

To find the probability that the average amount of lead in 50 batches is greater than 6.5 mg, we can use the Central Limit Theorem (CLT) and the properties of the normal distribution. The Central Limit Theorem states that for a large sample size (in this case, 50 batches), the distribution of sample means will approach a normal distribution regardless of the shape of the original distribution.

Given:

Mean value of lead in a batch (μ) = 6.0 mg

Standard deviation of lead in a batch (σ) = 2.0 mg

Sample size (n) = 50

To apply the CLT, we need to calculate the standard deviation of the sample means, also known as the standard error (SE), which is equal to the population standard deviation divided by the square root of the sample size:

SE = σ / √(n)

SE = 2.0 mg / √(50)

SE ≈ 0.2828 mg

Now, we can standardize the desired average amount of lead (6.5 mg) using the sample mean and the standard error:

Z = (X - μ) / SE

Z = (6.5 mg - 6.0 mg) / 0.2828 mg

Z ≈ 1.7678

We want to find the probability that the average amount of lead is greater than 6.5 mg, which is equivalent to finding the probability that the standardized value (Z) is greater than 1.7678. Using a standard normal distribution table or calculator, we can find the probability corresponding to a Z-value of 1.7678, which is approximately 0.038.

An angle θ with 0∘<θ<360∘ that has the same:

Sine function value as 230°: θ = 50° degrees
Cosine function value as 230°: θ = 130° degrees

To find an angle θ with 0° < θ < 360° that has the same sine and cosine function values as 230°, you can use the following methods:

For the sine function:

Since sine is positive in the first and second quadrants, you can find the reference angle for 230°, which is in the third quadrant. The reference angle is calculated by subtracting 180° from 230°:
230° - 180° = 50° (reference angle)

Now, to find the angle with the same sine value, we can use the first quadrant angle:
θ = 50° (since sine(50°) = sine(230°))

For the cosine function:

Since cosine is positive in the first and fourth quadrants, you can find the angle in the fourth quadrant that has the same cosine value as 230°. To do this, subtract 230° from 360°:
360° - 230° = 130°

So, the angle with the same cosine value is:

θ = 130° (since cosine(130°) = cosine(230°))

The probability that a randomly selected jury of 12 people is all male is 2.1 × 10⁻⁵.

What is the probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

An order does not matter so it is a Combination.

There are 16 men and we are going to choose 12 --> ₁₆C₁₂

There are 30 people and we are going to choose 12  --> ₃₀C₁₂

If the distribution of the variable upon which the mean was derived is highly skewed to the right, it may be appropriate to use the t-test if the sample size is large enough.

When conducting research, the t-test is typically used to compare the means of two groups. One of the key assumptions of the t-test is that the population from which the sample was drawn follows a normal distribution.

However, if the distribution of the variable upon which the mean was derived is highly skewed to the right, it may not meet the normality assumption.

In this case, it is appropriate to use the t-test if the sample size is large enough. The t-test is based on the central limit theorem, which states that the sample mean tends to follow a normal distribution as the sample size increases, even if the population distribution is not normal. For large sample sizes (typically n > 30), the t-test is generally considered to be robust to violations of the normality assumption.

However, if the sample size is small, the t-test may not be appropriate, even if the sample mean follows a normal distribution. In this case, alternative statistical tests may be more appropriate. For example, the Wilcoxon rank-sum test can be used to compare the means of two groups when the normality assumption is not met.

In conclusion, if the sample size is small, alternative statistical tests may be more appropriate.

In the absence of price discrimination, the profit-maximizing conditions would be different, and the resulting prices, quantities, total revenue, total cost, and profit would also be different.

To find the profit-maximizing conditions with third-degree price discrimination, we need to equate the marginal revenue (MR) to the marginal cost (MC) for each market segment.

Given the demand equations and the total cost function:

Market 1: Q1 = 160 - 10P1 or P1 = 16 - 0.1Q1

Market 2: Q2 = 200 - 20P2 or P2 = 10 - 0.05Q2

Total Cost: TC = 120 + 4Q

To find the profit-maximizing prices and quantities, we equate MR to MC for each market segment:

MR1 = MC:

16 - 0.2Q1 = 4

0.2Q1 = 12

Q1 = 60

MR2 = MC:

10 - 0.1Q2 = 4

0.1Q2 = 6

Q2 = 60

Substituting the quantities back into the demand equations, we find:

P1 = 16 - 0.1(60) = 10

P2 = 10 - 0.05(60) = 7

The total revenue (TR) can be calculated by multiplying the price by the quantity for each market segment:

TR = P1 * Q1 + P2 * Q2

TR = (10 * 60) + (7 * 60)

TR = 600 + 420

TR = 1020

The total cost (TC) is given by the total cost function:

TC = 120 + 4Q

TC = 120 + 4(60 + 60)

TC = 120 + 480

TC = 600

Finally, the profit (π) can be calculated by subtracting total cost from total revenue:

π = TR - TC

π = 1020 - 600

π = 420

In the absence of price discrimination, the profit-maximizing conditions would be different, and the resulting prices, quantities, total revenue, total cost, and profit would also be different.

The measure of one interior angle of a regular 16-gon is 157.5 degrees. This is obtained by using the formula (n-2) * 180° / n, where "n" represents the number of sides of the polygon. In this case, (16-2) * 180° / 16 = 157.5°..

To find the measure of one interior angle of a regular 16-gon, we can use the formula for the measure of an interior angle of a regular polygon:

Interior Angle = (n-2) * 180° / n

where "n" is the polygon's number of sides.

For a regular 16-gon, substituting the value of "n" into the formula, we get:

Interior Angle = (16 - 2) * 180° / 16

= 14 * 180° / 16

= 2520° / 16

= 157.5°

Therefore, the measure of one interior angle of a regular 16-gon is 157.5 degrees.

To understand the calculation, let's break it down. Equal interior angles and sides define a regular polygon. The sum of the interior angles of any polygon is given by the formula (n-2) * 180°, where "n" is the number of sides. In a regular polygon, all the interior angles are congruent, so to find the measure of one angle, we divide the sum by the number of sides.

In the case of a regular 16-gon, we subtract 2 from 16 to get 14, multiply it by 180°, and then divide by 16 to find that each interior angle measures 157.5°.

Therefore, the measure of one interior angle of a regular 16-gon is 157.5 degrees.

Answer:

3(p^(2)+4)

Step-by-step explanation:

a) To find the mean and variance of the difference in sample means, we can use the properties of sampling distributions. The mean of the difference in sample means is equal to the difference in population means:

Mean of the difference in sample means = Mean(Jack Creek) - Mean(Cataract Creek) = 1000 - 970 = 30

The variance of the difference in sample means is calculated by summing the variances of the two samples, divided by their respective sample sizes:

Variance of the difference in sample means = (Variance(Jack Creek) / Sample Size of Jack Creek) + (Variance(Cataract Creek) / Sample Size of Cataract Creek)

Variance of Jack Creek = (standard deviation of Jack Creek)^2 = 40^2 = 1600

Variance of Cataract Creek = (standard deviation of Cataract Creek)^2 = 20^2 = 400

Sample Size of Jack Creek = 30

Sample Size of Cataract Creek = 15

Variance of the difference in sample means = (1600 / 30) + (400 / 15) = 53.33 + 26.67 = 80

Therefore, the mean of the difference in sample means is 30 and the variance of the difference in sample means is 80.

b) To find the probability that the average amount of dissolved metals at Jack Creek is at least 50 more than the average amount at Cataract Creek, we can calculate the probability using the properties of the normal distribution.

Let X be the average amount of dissolved metals at Jack Creek and Y be the average amount at Cataract Creek.

We need to find P(X - Y >= 50). This can be rephrased as P(X >= Y + 50).

Using the properties of normal distributions, we can standardize the random variables X and Y:

Z = (X - Mean(X)) / (Standard Deviation(X)) = (X - 1000) / 40

W = (Y - Mean(Y)) / (Standard Deviation(Y)) = (Y - 970) / 20

Now we can rephrase the probability in terms of Z and W:

P(X >= Y + 50) = P(Z >= (W + 50 - 1000) / 40) = P(Z >= (W - 950) / 40)

To find this probability, we can look up the corresponding value in the standard normal distribution table or use statistical software.

Step-by-step explanation: 12+16+8+4 is equal to 40. 40 minus the number of brown m&ms is 24 .24/40 as a percentage is 60%. Hope this helps!!!

the solution to the equation log3 x=4 is x = 81.The equation "log3 x=4" is a logarithmic equation with a base of 3.

It means that 3 raised to the power of 4 is equal to x. In other words, x is the value that satisfies the equation 3^4 = x.

To solve this equation, we need to isolate the variable x. We can do this by taking the exponential of both sides of the equation with a base of 3. This will cancel out the logarithm on the left side of the equation, leaving us with:

3^(log3 x) = 3^4

The base of the exponential function and the logarithmic function cancel each other out, and we're left with:

x=14

2y+35=95

2y=60

y=30

(I assumed all of the angles are equal, correct me if I'm wrong.)

Answer:x=14

Step-by-step explanation:

Let's first understand what we need to do. We need to solve for two variables, x and y. We do these by setting two systems of equations equal to each other. This is easily done for x, but for y the other equation is missing. Keep this in mind for later.

So, we will first start off by solving for x. We do this by using inverse operations.

5x+25=3x+53 We will subtract

5x=3x+28

2x=28 Divide

x=14

You can plug 14 into both the xs and they will be similar, and both will have the similar results once you solve for y and plug it into the equation along with x.

We know that the 5x+25 on the left is adjacent to 2y+35, and so is the second x. Adjacent angles add up to 180 total, and so to solve for y we need to plug 12 in the first x.

5(14)+25=95

180-95=85

85 is the value of 2y+35

We will solve for y just like any other alegrbaic problem

85=2y+35

50=2y

y=25

We know know that y is 25 and x is 14

Plug both values into 2 adjacent angles and they will add up to 180.

what is square matrix?

A square matrix is a matrix that has the same number of rows and columns. That is, a matrix A is square if A has dimensions n x n, where n is a positive integer.

To show that det AB = det BA, we can use the fact that for any invertible matrix M, we have det(MAB) = det(MBA) = det(M) * det(AB) = det(M) * det(BA). Therefore, it is sufficient to show that there exists an invertible matrix M such that det(MAB) = det(MBA).

Let M be the diagonal matrix with diagonal entries given by the determinant of A, i.e., M = diag(det A, det A, ..., det A). Then, we have:

det(MAB) = det(diag(det A, det A, ..., det A)AB) = det(diag(det A, det A, ..., det A)) * det(AB)

= det A * det(AB)

Similarly, we have:

det(MBA) = det(diag(det A, det A, ..., det A)BA) = det(diag(det A, det A, ..., det A)) * det(BA)

= det A * det(BA)

Therefore, det AB = det BA, as required.
