A. Probability Experiment F or G = {5, 6, 7, 8, 9, 10, 11, 12}

B. Probability Experiment F or G = {5, 6, 7, 8, 9, 10, 11, 12}

C. Probability Experiment P(F or G) = 8/12 = 0.667

The outcomes in F or G are the elements that are present in either F or G or both. Therefore, the list of outcomes in F or G is as follows:

F or G = {5, 6, 7, 8, 9, 10, 11, 12}

P(F or G), we count the number of outcomes in F or G and divide it by the total number of outcomes in the sample space.

Number of outcomes in F or G = 8

Total number of outcomes in the sample space = 12

P(F or G) = Number of outcomes in F or G / Total number of outcomes in the sample space

P(F or G) = 8/12 = 0.667 (rounded to three decimal places)

Using the general addition rule, we can express P(F or G) as the sum of the individual probabilities of events F and G minus the probability of their intersection.

P(F or G) = P(F) + P(G) - P(F and G)

P(F) = Number of outcomes in F / Total number of outcomes in the sample space = 5/12

P(G) = Number of outcomes in G / Total number of outcomes in the sample space = 4/12

P(F and G) = Number of outcomes in both F and G / Total number of outcomes in the sample space = 1/12

Substituting these values into the general addition rule:

P(F or G) = P(F) + P(G) - P(F and G) = 5/12 + 4/12 - 1/12 = 8/12 = 0.667 (rounded to three decimal places)

There are no more common factors or like terms that can be further simplified, the expression 3x - 12 is already in its completely factored form.

Therefore, the answer is:c) 3(x - 4)

To factor completely the expression 3x - 12, we can first look for a common factor among the terms. In this case, both 3x and 12 have a common factor of 3.

We can factor out the common factor of 3 from both terms:

3x - 12 = 3(x) - 3(4)

Now, we can simplify the expression:

3x - 12 = 3x - 12

Since there are no more common factors or like terms that can be further simplified, the expression 3x - 12 is already in its completely factored form.

Therefore, the answer is:c) 3(x - 4).

The probability that a person arriving to use the machine will find it idle is 1/3 or 0.3333. Option a is correct.

Use the concept of an M/M/1 queue to calculate the probability, which models a single-server queue with exponential interarrival times and exponential service times.

In this case, the interarrival time follows an exponential distribution with a rate parameter of λ = 5 persons per hour (or 1/12 persons per minute). The service time (copying time) also follows an exponential distribution with a rate parameter of μ = 1/8 persons per minute (since each person uses the machine for an average of 8 minutes).

In an M/M/1 queue, the probability that the system is idle (no person is being served) can be calculated as:

P_idle = ρ⁰ × (1 - ρ), where ρ is the traffic intensity, defined as the ratio of the arrival rate to the service rate. In this case, ρ = λ/μ.

Plugging in the values, we have:

ρ = (1/12) / (1/8) = 2/3

P_idle = (2/3)⁰ × (1 - 2/3) = 1/3

Therefore, the probability is 1/3 or approximately 0.3333.

Thus, option (A) is the correct answer.

Blair received 15 bars as the average weight of the bars given to Brennan (light), Blair, and Maya, as well as the average weight of the bars given to the other recipients.

The weighted average is calculated by adding up all the variables, multiplying by their weight, and dividing by the sum of the weights. Instead of treating each item equally, a weighted average or mean multiplies each item being averaged by a number based on its relative importance. The weights or weightings correspond to including that many comparable items of the same value in the average.

Here,

The average weight of the bars given to Brennan (light), Blair, and Maya was higher than the average weight of the bars given to the other two recipients (heavy).

Let X represent the combined weight of all the bars.

The weight of the bars Brennan was given was equal to 45% of X, or 0.45X.

Maya was given bars that weighed 26% of X, or 0.26X.

The weight of the bars Claire was given was the rest, or 29% of X, or 0.29X.

Brennan received bars with an average weight of 0.45 x/ 24.

The weight of the Maya-received bars, on average, is 0.26X/13.

Similar to the previous example, if Blair receives B bars, then their average weight is 0.29X/B.

The width of the new rectangular field would be 0 meters, which means it would essentially be a line segment.

To find the length and width of another rectangular field that has the same perimeter but a larger area, we can use the following steps:

1. Calculate the perimeter of the given rectangular field:

  Perimeter = 2 * (Length + Width)

            = 2 * (120 meters + 80 meters)

            = 2 * 200 meters

            = 400 meters

2. Divide the perimeter by 2 to find the equal sides of the new rectangular field. Since the perimeter is divided equally into two sides, each side would be half of the perimeter length:

  Side length = Perimeter / 2

             = 400 meters / 2

             = 200 meters

3. Now, we have the side length of the new rectangular field. However, we need to determine the length and width that would yield a larger area. One way to achieve this is to make one side longer and the other side shorter.

4. Let's assume the length of the new rectangular field is 200 meters. Since both sides have the same length, the width can be calculated using the formula for the perimeter:

  Width = Perimeter / 2 - Length

        = 400 meters / 2 - 200 meters

        = 200 meters - 200 meters

        = 0 meters

5. Therefore, the width of the new rectangular field would be 0 meters, which means it would essentially be a line segment. However, note that the question asks for a rectangular field with a larger area. Since the width cannot be zero, we can conclude that it is not possible to have a rectangular field with the same perimeter but a larger area than the given field.

In summary, it is not possible to find another rectangular field with the same perimeter but a larger area than the rectangular field with dimensions 80 meters wide and 120 meters long.

Alright, let's break this down into simple steps! ✈️

We have a daily airline flight to Denver, and the number of checked pieces of luggage is normally distributed. Picture a bell-shaped curve, kind of like an upside-down U.

The middle of this curve is the average (or mean) number of luggage checked in. In this case, the mean is 380. The spread of this curve, how wide or narrow it is, depends on the standard deviation. Here, the standard deviation is 20.

Now, we want to find out what number of checked pieces of luggage is 3 standard deviations above the mean. Imagine walking from the center of the curve to the right. Each step is one standard deviation. So, we need to take 3 steps.

Let's do the math:

1. One standard deviation is 20.

2. Three standard deviations would be 3 times 20, which is 60.

3. Now, we add this to the mean (380) to move right on the curve.

380 (mean) + 60 (three standard deviations) = 440.

So, 440 is the number of checked pieces of luggage that is 3 standard deviations above the mean. This is quite a lot compared to the average day and would represent a day when a very high number of pieces of luggage are being checked in.

Think of it like this: if you're standing on the average number 380 and take three big steps to the right, each step being 20, you'll end up at 440! ‍♂️‍♂️‍♂️

An unfair coin has probability 0.3 of landing heads. the coin is tossed three times. The probability that it lands heads at least once is 0.657

The probability of getting a head = 0.3

Probability of not getting a head = 1- 0.3 = 0.7

Probability of getting at least one head in three tosses = 1 - probability of getting no head in 3 tosses

Since, the outcome of each toss is independent,

Probability of getting no head in 3 tosses = 0.7 * 0.7 * 0.7 = 0.343

Probability of getting at least one head in three tosses = 1 - 0.343 = 0.657

Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

To find out how much of each leftover paint Josh should mix to achieve a medium pink color (50% red), we can set up a system of equations based on the percentages of red in the paints.

Let's assume that Josh needs x gallons of dark pink paint and y gallons of light pink paint to achieve the desired color.

The total amount of paint needed is 3 gallons, so we have the equation:

x + y = 3

The percentage of red in the dark pink paint is 80%, which means 80% of x gallons is red. Similarly, the percentage of red in the light pink paint is 30%, which means 30% of y gallons is red. Since Josh wants a 50% red mixture, we have the equation:

(80/100)x + (30/100)y = (50/100)(x + y)

Simplifying this equation, we get:

0.8x + 0.3y = 0.5(x + y)

Now, we can solve this system of equations to find the values of x and y.

Let's multiply both sides of the first equation by 0.3 to eliminate decimals:

0.3x + 0.3y = 0.3(3)

0.3x + 0.3y = 0.9

Now we can subtract the second equation from this equation:

(0.3x + 0.3y) - (0.8x + 0.3y) = 0.9 - 0.5(x + y)

-0.5x = 0.9 - 0.5x - 0.5y

Simplifying further, we have:

-0.5x = 0.9 - 0.5x - 0.5y

Now, rearrange the equation to isolate y:

0.5x - 0.5y = 0.9 - 0.5x

Next, divide through by -0.5:

x - y = -1.8 + x

Canceling out the x terms, we get:

-y = -1.8

Finally, solve for y:

y = 1.8

Substitute this value of y back into the first equation to solve for x:

x + 1.8 = 3

x = 3 - 1.8

x = 1.2

Therefore, Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

The correct option is b. mutually exclusive. two events for which the intersection is the null set are called mutually exclusive.

Mutually exclusive events are events that cannot occur simultaneously. The occurrence of one event means the other event cannot occur. The intersection of mutually exclusive events is always an empty set because they cannot have any outcomes in common. For example, rolling a 1 on a die and rolling a 2 on the same die are mutually exclusive events because they cannot occur at the same time. The intersection of rolling a 1 and rolling a 2 is the null set because they have no outcomes in common. In contrast, independent events can occur simultaneously and their intersection is not necessarily empty. For instance, rolling a 1 on one die and rolling a 2 on another die are independent events, and their intersection is not the null set.

The sum of the interior angles for a pentagon is 540°

Sum of Interior Angles of a Pentagon :

The interior angles of a pentagon sum up to 540 degrees.. Regardless of how regular or irregular the pentagon is, this is true. By dividing the whole amount by 5, we can calculate the size of each internal angle in the case of regular pentagons. To determine the measure of a missing angle in the situation of irregular pentagons, we must first know the measurements of other angles.

Any pentagon's internal angles add up to 540° in the same way. This holds true regardless of how regular or irregular the pentagon is. By using the polygon angle sum formula, the following sum is obtained:

(n-2)180(n−2)×180°

where n represents the polygon's number of sides. We have n = 5 in the case of a pentagon. Consequently, utilizing the formula:

=(n-2)180=(n−2) ×180°

= (5-2) 180= (5−2) ×180°

= (3) 180= (3) ×180°

= 540=540°

Consequently, a pentagon's interior angles add up to 540 degrees.
