77/9 is the correct awnser simplufied is -8 5/9 or -8.5

Step-by-step explanation:

The presence of a negative externality causes the MSC to be higher than the MSB, which leads to the market over-producing the good. This is because producers are only taking their private costs and benefits into account, not the costs and benefits to society as a whole. The difference between the private and social optima is known as the deadweight loss. In this case, the deadweight loss is equal to the shaded triangle in the attached image.

1. This is a negative externality. We can see this by the MSC being higher than the MSB. This means that the cost to society of producing the good is higher than the benefit to society, resulting in the market over-producing the good.2. See the attached image. 3. At private decision making, we set the MSB equal to the MPC: 12-0.5Q = 2+0.5Q. Solving for Q gives Q = 8. 4. To find the socially optimal quantity, we need to set MSB equal to MSC: 12-0.5Q = 2+1.5Q. Solving for Q gives Q = 4. 5. The private and social optima are different because of the negative externality.

Step-by-step explanation:

Anna should use 10 mL of the 72% salt solution and 20 mL of the 54% salt solution to make 30 mL of a 60% salt solution

Let's assume that Anna will use x mL of the 72% salt solution, and therefore she will use (30 - x) mL of the 54% salt solution (since the total volume is 30 mL).

To find out how much of each solution Anna should use, we can set up an equation based on the amount of salt in each solution.

The amount of salt in x mL of 72% salt solution is

= 0.72x

The amount of salt in (30 - x) mL of 54% salt solution is

= 0.54(30 - x)

To make a 60% salt solution, the total amount of salt in the final solution should be

0.6(30) = 18

So we can set up an equation

0.72x + 0.54(30 - x) = 1

Simplifying the equation

0.72x + 16.2 - 0.54x = 18

0.18x = 1.8

x = 10 ml

In a standard 52-card deck, there are 20,358 ways to pick an (unordered) subset of 6 cards that contains at least one Ace, at least one King, at least one Queen, and at least one Jack.

When selecting a subset of 6 cards from a standard 52-card deck, the main objective is to ensure that the subset contains at least one Ace, one King, one Queen, and one Jack. To calculate the number of ways this can be achieved, we can break it down into steps.

Step 1: Select one Ace, King, Queen, and Jack

There are 4 ways to choose one Ace, 4 ways to choose one King, 4 ways to choose one Queen, and 4 ways to choose one Jack.

Step 2: Select two additional cards from the remaining 48 cards

After selecting one Ace, one King, one Queen, and one Jack, we are left with 48 cards. To complete the subset of 6 cards, we need to choose two more cards from this remaining set. The number of ways to select two cards from 48 is calculated using combinations, denoted as "48 choose 2," which is equal to 1,128.

Step 3: Multiply the results

To determine the total number of ways, we multiply the results of each step. Therefore, the total number of ways to pick an (unordered) subset of 6 cards that contains at least one Ace, one King, one Queen, and one Jack is 4 * 4 * 4 * 4 * 1,128 = 20,358.

Answer:

A. The rate of change of the cost of the taxi ride is $3.00 per minute.

Step-by-step explanation:

The approximate length of the midsegment parallel to xy is 6.63

The midsegment of a triangle is a line segment that connects the midpoints of two sides of the triangle and has the same length as each of the two sides.

To find the midpoint of a line segment, we average the x-coordinates and the y-coordinates of its endpoints.

Since the question stated that the midsegment is parallel to xy, we need to find midpoint of xw and yw.

First, let's find the midpoint of side xw:

Midpoint of xw : ((-14+10)/2, (20+4)/2) = (-2, 12)

Midpoint of yw : ((-14-2)/2, (20-4)/2) = (-8, 8 )

The length of a line segment between two points (x1, y1) and (x2, y2) in a two-dimensional coordinate system can be calculated using the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Length line of midpoint xw and midpoint yw :

√((-2-(-8))^2 + (12-(8))^2) = √(6^2 + 4^2) = √(36 + 8) = √44

So, the length of the midsegment is parallel to XY, which is approximately equal to √44 = 6.63

Substituting this value back into the equation m∠EFD = 2x - 3, we can find the measure of angle EFD.

m∠EFD = 2(46.5) - 3 = 93 - 3 = 90 degrees.

To find the measure of angle EFD, we can use the fact that the angles in a rectangle are all right angles, or 90 degrees.

Given that DEFG is a rectangle, we know that angle EFD is a right angle.

Therefore, m∠EFD = 90 degrees.

We are also given that m∠EFD = 2x - 3 and m∠DFG = x + 12.

Since m∠EFD = 90 degrees, we can set up the equation 2x - 3 = 90 and solve for x.

Adding 3 to both sides, we get 2x = 93.

Dividing both sides by 2, we find that x = 46.5.

Therefore, the measure of angle EFD is 90 degrees.

Answer:

D. Cost

Step-by-step explanation:

In a scatter diagram we have that the x axis corresponds to the explanatory variable or also called the independent variable, since it is the value that is entered in the equation and does not depend on another.

While the y-axis corresponds to the response variable or also called the dependent variable since it is the value of the result of the equation

In this case, the explanatory variable is weight, that is, on the x-axis the weight would go and the cost is the response variable and would go on the y-axis, therefore, the answer is D. Cost

Let's calculate the products and check if they indeed have the same value:

Product of 32 and 46:

32 * 46 = 1,472

Reverse the digits of 23 and 64:

23 * 64 = 1,472

As you mentioned, the products are the same. This phenomenon is not unique to this particular pair of numbers. In fact, it occurs with any pair of two-digit numbers whose digits, when reversed, are the same as the product of the original numbers.

To find two other pairs of two-digit numbers that have this property, we can explore a few examples:

Product of 13 and 62:

13 * 62 = 806

Reversed digits: 31 * 26 = 806

Product of 17 and 83:

17 * 83 = 1,411

Reversed digits: 71 * 38 = 1,411

As for determining if a given pair of two-digit numbers will have this property without actually performing the multiplication, there is a simple rule. For any pair of two-digit numbers (AB and CD), if the sum of A and D equals the sum of B and C, then the products of the original and reversed digits will be the same.

For example, let's consider the pair 25 and 79:

A = 2, B = 5, C = 7, D = 9

The sum of A and D is 2 + 9 = 11, and the sum of B and C is 5 + 7 = 12. Since the sums are not equal (11 ≠ 12), we can determine that the products of the original and reversed digits will not be the same for this pair.

Therefore, by checking the sums of the digits in the two-digit numbers, we can determine whether they will have the property of the products being the same when digits are reversed.

1. The population parameter are we trying to build an interval estimate for is p2 - p1.

2. The sample estimate for this quantity is 5000.

3. The standard error for the original sample statistic is μ

4. The center of your bootstrap distribution is variability.

5.  The bootstrap distribution represents many possible values of the sample statistic

6. The 95% confidence interval for the population parameter is 2.5 percentile

The population parameter we are trying to estimate is the difference in proportions between Republicans and Democrats who think that the COVID-19 situation is getting better. We can represent this parameter as p1 - p2, where p1 is the proportion of Republicans who think the COVID-19 situation is getting better, and p2 is the proportion of Democrats who think the COVID-19 situation is getting better.

To calculate the sample estimate for this quantity, we need to collect data from a sample of Republicans and Democrats and calculate the difference in proportions who think the COVID-19 situation is getting better.

To build a bootstrap confidence interval, we first create a bootstrap distribution by resampling our original sample with replacement many times at least 5,000 times.

The center of our bootstrap distribution is the mean of the bootstrap samples, which is an estimate of the true population parameter. We can represent this center as the mean of our bootstrap distribution, denoted as μ.

The center of the bootstrap distribution is likely to be close to the sample estimate, but it may be slightly different due to the variability in the bootstrap samples.

To compute the 95% confidence interval, we need to find the range of values in our bootstrap distribution that contains 95% of the values. We can do this by finding the 2.5th percentile and the 97.5th percentile of the bootstrap distribution, which represent the lower and upper bounds of our confidence interval.

The probability that a random sample of 30 healthy koalas has a mean body temperature of more than 36.2°C is 0.006.

To find the probability, we can use the Central Limit Theorem since the sample size is large (n = 30). According to the Central Limit Theorem, the sampling distribution of the sample mean approaches a normal distribution with a mean equal to the population mean (35.6°C) and a standard deviation equal to the population standard deviation divided by the square root of the sample size (1.3°C/sqrt(30)).

Now, we can standardize the sample mean using the formula z = (x - μ) / (σ / sqrt(n)), where x is the desired value (36.2°C), μ is the population mean (35.6°C), σ is the population standard deviation (1.3°C), and n is the sample size (30).

Calculating the z-score, we get z = (36.2 - 35.6) / (1.3 / sqrt(30)) ≈ 1.516.

To find the probability that the sample mean is more than 36.2°C, we need to find the area to the right of the z-score on the standard normal distribution. Consulting a standard normal distribution table or using a calculator, we find that the probability is approximately 0.006, rounded to three decimal places.
