The Martinez family just bought 6 crates of eggs, and each crate had 12 eggs. The family already had 9 eggs in their refrigerator. Total number of eggs they have now is 81.

The problem states that the Martinez family bought 6 crates of eggs, and each crate had 12 eggs. So, we can start by multiplying the number of crates by the number of eggs per crate to find out how many eggs they bought in total:

6 crates x 12 eggs/crate = 72 eggs

This tells us that the family now has 72 eggs. However, the problem also states that the family already had 9 eggs in their refrigerator. To find out how many eggs they have now in total, we need to add the number of eggs they bought to the number of eggs they already had:

72 eggs + 9 eggs = 81 eggs

So the answer is that the Martinez family now has a total of 81 eggs.

A truthful set of statistics regarding a rise in vehicle theft over the course of a year in a city might not reflect the actual situation in several ways.

Here are a few possible examples:

Underreporting or overreporting: The statistics might be based on police reports of stolen vehicles, which may not capture all incidents of vehicle theft in the city. For instance, some victims may not report the theft to the police, or some incidents may be misclassified as other types of crime. Similarly, the statistics might include some incidents that are not actually vehicle thefts, such as cases where the vehicle was recovered undamaged or cases where the vehicle was not actually stolen, but rather borrowed without permission.

Geographical bias: The statistics might show an overall rise in vehicle thefts, but fail to capture the fact that the increase is concentrated in certain parts of the city. For example, a rise in thefts in a particular neighborhood might be masked by a decrease in thefts in other areas of the city.

Seasonal or temporal bias: The statistics might show an increase in vehicle thefts over the course of a year, but fail to account for seasonal or temporal factors that could be driving the increase. For instance, thefts might be more common during certain times of year (e.g., the summer) or on certain days of the week (e.g., weekends). If the statistics do not adjust for these factors, they might misrepresent the true trend in vehicle thefts.

Demographic bias: The statistics might show an increase in vehicle thefts overall, but fail to capture the fact that the rise is driven by thefts of certain types of vehicles or in certain neighborhoods. For example, if the increase is largely driven by thefts of high-end vehicles or in affluent areas, the statistics might not reflect the experiences of people who own less expensive vehicles or live in less affluent areas.

Overall, it's important to interpret statistical data with a critical eye and consider the limitations of the data source and methodology before drawing conclusions about the real-world situation.

Michael is now (B) 6 years old.

Let's start by defining variables for the current ages of Norman and Michael.

Let N be Norman's current age, and M be Michael's current age.

From the problem statement, we know that N = M + 12 (Norman is 12 years older than Michael).

We also know that in 6 years, Norman will be twice as old as Michael.

So we can set up the following equation:

N + 6 = 2(M + 6)

Substituting N = M + 12 into the equation, we get:

M + 12 + 6 = 2(M + 6)

Simplifying:

M + 18 = 2M + 12

M = 6

Therefore, Michael is currently 6 years old.

Answer:

So the simplified expression is:

2x - 4 / (x^2 + 9x + 20)

Step-by-step explanation:

To simplify the expression, we need to simplify the numerator and denominator separately, and then simplify the entire expression.

Starting with the numerator:

4x^2 + 12x - 16

For the denominator:

The first fraction: 2x + 10 can be simplified as follows: 2x + 10 = (2)(x) + (2)(5) = 2x + 10

The second fraction: 6x + 24 over x^2 + 9x + 20

We can simplify the denominator by using partial fraction decomposition. To do that, we need to write the denominator as a sum of simpler fractions, each with a numerator that is a constant. In other words, we write:

6x + 24 / (x^2 + 9x + 20) = (A x + B) / (x^2 + 9x + 20) + (C x + D) / (x^2 + 9x + 20)

Multiplying both sides by the denominator, we get:

6x + 24 = (A x + B)(x^2 + 9x + 20) + (C x + D)(x^2 + 9x + 20)

Expanding the right-hand side, we obtain:

6x + 24 = Ax^3 + (A 9 + B) x^2 + (A 20 + B 9 + C) x + (B 20 + D)

Comparing the coefficients of the polynomials on both sides, we get the following system of linear equations:

A = 0

B = 6

C = 0

D = -24

Therefore, the partial fraction decomposition of the denominator is:

6x + 24 / (x^2 + 9x + 20) = (6x + 24) / (x^2 + 9x + 20)

Putting it all together, we have:

4x^2 + 12x - 16 / (2x + 10) / (6x + 24) / (x^2 + 9x + 20) = (4x^2 + 12x - 16) / (2x)(6x + 24) / (x^2 + 9x + 20) = 2x - 4 / (x^2 + 9x + 20)

So the simplified expression is:

2x - 4 / (x^2 + 9x + 20)

Option D. The faculty should use the median to make their argument. The median will be lower than the mean since the mean is influenced by the few extremely high salaries.

Mean is the average of any data set whereas the median is the middle value we get after arranging the data in ascending order.

So for example, if the salaries of any 5 faculty members are as follows:

$10,000 , $50,000 , $80,000 , $150,000 , $160,000

Mean= (10,000+50,000+80,000+150,000+160,000) / 5

Mean= $90,000

Median= (5+1) / 2

Median= 6/2

Median= 3rd value

As the data is already arranged in ascending order, Median is $80,000

Hence, if the faculty want to give the community the impression that they deserve higher salaries, they should advertise the median of their current salaries.

The probability that the next component brought in for repair is a compact disc player given that it is already known to be an audio component is 0.83 or 83%.

Probability is a fundamental concept in mathematics, statistics, and various fields of science. It is used to measure the likelihood of an event occurring

In the given scenario, we are told that a certain shop repairs both audio and video components. Let A denote the event that the next component brought in for repair is an audio component, and let B be the event that the next component is a compact disc player. We are also given that P(A) = 0.6 and P(B) = 0.5.

The probability of B given A, denoted by P(B|A), represents the probability that event B will occur given that event A has already occurred. In other words, it tells us how likely it is that the next component brought in for repair is a compact disc player given that it is already known to be an audio component.

To calculate P(B|A), we use the formula for conditional probability:

P(B|A) = P(A and B) / P(A)

Here, P(A and B) denotes the probability that both events A and B occur. We know that event B is contained in event A, so it follows that P(A and B) = P(B). Therefore:

P(B|A) = P(B) / P(A)

Substituting the given values, we have:

P(B|A) = 0.5 / 0.6

P(B|A) = 5/6 or 0.83 (rounded to two decimal places)

Answer:

Expected amount = $1.50

Step-by-step explanation:

Let's get a couple of definitions out of the way to understand how to compute the expected value given probabilities

Random Variable is a set of possible values from a random experiment.
We usually denote a random variable using the sets of possible values that the variable can take.

When we toss a fair die, the probability of getting a single number = 1/6 since there are 6 possible outcomes

The probability of getting 2 given numbers say 1 or 2 is twice 1/6 = 2 x 1/6 = 2/3 and so on

The expected value of each outcome is the value attached to each outcome x probability of that outcome

As an example, P(1 or 2) = 2/6 = 1/3

Payout = $3

Expected payout = 3 x 1/3 = $1

The table below summarizes the outcomes, probabilities, payouts and expected payouts

Outcome             Probability              Payout              Expected Payout
                                                                                     (Payout x probability)

X = {1 or 2}            2/6 = 1/3                  $3                     $3 x 1/3 = $1

X = {3}                       1/6                       $5                     $5 x 1/6 = $5/6

X = {4 or 5}           2/6 = 1/3                  $0                      $0 x 1/3 = $0

X = {6}                        1/6                      -2$                     -$2 x 1/6 = -$2/6

The expected payout in the long run is the sum of the individual expected payouts

= $1 + $5/6 + $0 - $2/6    (5/6 - 2/6 = 3/6)

= $1 + $3/6             (3/6 = $0.50)

= $1 + $0.50

= $1.50

The expected value of the game is $2. This means that if you play the game many times, you can expect to win an average of $2 per game in the long run.

It is a branch of mathematics that deals with the occurrence of a random event.

To determine whether you should play the game, we need to calculate the expected value of the game.

The expected value is the sum of the product of each outcome and its probability.

The outcomes and their corresponding probabilities are:

Win $3 with probability 1/3 (if the number is 1 or 2)

Win $5 with probability 1/6 (if the number is 3)

Win $0 with probability 2/6 = 1/3 (if the number is 4 or 5)

Lose $2 with probability 1/6 (if the number is 6)

Using these probabilities and outcomes, we can calculate the expected value as:

Expected value = (3 × 1/3) + (5 × 1/6) + (0 × 1/3) + (-2 × 1/6)

= 1 + 5/6 - 1/6

= 1.666

= 2

Hence, the expected value of the game is $2. This means that if you play the game many times, you can expect to win an average of $2 per game in the long run.

The probability that a student choosen at random likes english but not maths is 299/676.

Let A be the event that a student likes math, and B be the event that a student likes English.

From the given information, we know that:

P(A) = 15/26

P(B) = 13/26

P(neither A nor B) = 9/26

To find the probability that a student chosen at random likes English but not math, we can use the formula:

P(B and not A) = P(B) - P(A and B)

The probability of A and B can be found by multiplying the probabilities of A and B together, since they are not independent:

P(A and B) = P(A) × P(B) = (15/26) × (13/26) = 195/676

Substituting the given probabilities into the formula, we get:

P(B and not A) = (13/26) - (195/676)

Simplifying, we get:

P(B and not A) = 299/676

Therefore, the probability that a student chosen at random likes English but not math is 299/676.
