The value of C is 0.03030 if the f(x, y) = c(x 2y), x = 1, 2 and y =1, 2, 3  because the sum of the probability is always 1

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

f(x, y) = c(x+2y),

x = 1, 2 and y =1, 2, 3

f(1, 1) = C(1 + 2)  = 3C

f(1, 2) = C(1 + 4)  = 5C

f(1, 3) = C(1 + 6)  = 7C

f(2, 1) = C(2 + 2)  = 4C

f(2, 2) = C(2+ 4)  = 6C

f(2, 3) = C(2 + 6)  = 8C

We know the sum of the all probability is 1

3C+5C+7C+4C+6C+8C=1

33C =1

C = 0.03030

Thus, the value of C is 0.03030 if the f(x, y) = c(x 2y), x = 1, 2 and y =1, 2, 3  because the sum of the probability is always 1

Given that:

Distance travel by vehicle = 6,500 km

Time taken by vehicle = 13 hour  

Find:

Speed of vehicle in kilometer per hour

Computation:

Speed = Distance / Time

Speed of vehicle = Distance travel by vehicle / Time taken by vehicle

Speed of vehicle = 6,500 / 13

Speed of vehicle = 500 kilometer per hour

Answer:

We can start solving this problem by using the rate of work formula:

Work = rate x time

We can use this formula to find the time it takes for Danny and Olivia to fill the same number of baskets.

Let's say that the number of baskets they will fill before lunch is "n".

We know that Danny is filling baskets at a rate of 5 baskets per hour and Olivia is filling baskets at a rate of 4 baskets per hour. So, we can write the following equation:

n = 5t + 11 (Danny's work)

n = 4t + 12 (Olivia's work)

We can set the two equations equal to each other and solve for t:

5t + 11 = 4t + 12

t = 1

So, it will take them 1 hour to fill the same number of baskets.

Now that we know the time it takes for them to fill the same number of baskets, we can use that information to find the number of baskets they will have filled by then.

We know that Danny is filling baskets at a rate of 5 per hour and has already filled 11 baskets, so we can use the work formula to find the number of baskets he will have filled by then:

Work = rate x

For a symmetric distribution, the left whisker extends from the median to the minimum value in the dataset.

The left whisker represents the lower values or the lower tail of the distribution. It is also referred to as the "lower whisker" or the "whisker on the left side". The length of the left whisker may vary depending on the spread or range of the data.

In a box plot or box-and-whisker plot, the left whisker represents the lower values or the lower tail of the distribution. It indicates the range of values that lie below the median. The length of the left whisker is determined by the spread or range of the data.

If the data has a smaller range and is more tightly clustered around the median, the left whisker will be shorter. This indicates that the lower values in the dataset are relatively close to the median. On the other hand, if the data has a larger range and is more spread out, the left whisker will be longer. This suggests that the lower values in the dataset are more dispersed or spread out from the median.

Answer: True, if it is on a coordinate grid.

Step-by-step explanation:

The sprinkler system can water 2.4 hectares of land in 1 hour.

To find out how many hectares of land the sprinkler system can water in 1 hour, we need to use the unit rate of land watered per time. Since the system waters 0.6 hectares in 1/4 hour, we can set up a proportion:

0.6 hectares / 1/4 hour = x hectares / 1 hour

To solve for x, we can cross-multiply:

0.6 hectares * 4 = x hectares * 1

2.4 hectares = x

Therefore, the sprinkler system can water 2.4 hectares of land in 1 hour.

Paul should buy 3 gallons

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.

Thus, unit price of something is price of 1 thing.

Thus, suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.

There are 16 cups in a gallon, and if each person will eat 2 cups, and there are 24 people, multiply 24 by 2 to get the number of cups.

24 x 2 = 48.

Then, divide that by 16 (the number of cups in a gallon) to how many gallons.

The equation of the line with no slope that passes through the point (-2, 0) is x = -2.

A line with no slope is a vertical line. A vertical line is parallel to the y-axis and has the equation x = c, where c is a constant. In this case, we need to find the equation of a vertical line that passes through the point (-2, 0).

Since the line is vertical, its x-coordinate remains constant for all y-values. In this case, the x-coordinate is -2. Therefore, the equation of the line is x = -2.

The equation x = -2 represents a vertical line passing through the point (-2, 0). It means that for any value of y, the corresponding x-value is always -2. In other words, the line is a vertical line that intersects the x-axis at x = -2 and extends infinitely in the positive and negative y-directions.

The slope of a vertical line is undefined because it does not change in the x-direction. A vertical line only has a y-intercept, which in this case is (0, -2). The line is perpendicular to the x-axis and does not have a slope.

The probability of failure (q) = 1-p = 1-0.04 = 0.06

Total number of customers in sample (n) = 20

we have to find out the probability that exactly two customers in the sample will default on their payments.

Using the Binomial probability distribution,

P(X=x)= ⁿCₓ(p)ˣ(q)⁽ⁿ⁻ˣ⁾

the required probability is P(X= 2 )

Now, P(X= 2) = ²⁰C₂(0.04)²(0.06)¹⁸

A discrete probability distribution is a statistical distribution that relates to a set of outcomes that can take on a countable number of values, whereas a continuous probability distribution is one that can take on any value within a given range.Therefore, the main difference between the two types of distributions is the type of outcomes that they apply to.

An example of a discrete probability distribution is the probability of getting a particular number when a dice is rolled. The possible outcomes are only the numbers one through six, and each outcome has an equal probability of 1/6. Another example is the probability of getting a certain number of heads when a coin is flipped several times.

On the other hand, an example of a continuous probability distribution is the distribution of heights of students in a school. Here, the range of heights is continuous, and it can take on any value within a given range.

The expected value of a probability distribution measures the central tendency or average of the distribution. In other words, it is the long-term average of the outcome that would be observed if the experiment was repeated many times.

For a discrete probability distribution, the expected value is computed by multiplying each outcome by its probability and then adding the results. In mathematical terms, this can be written as E(x) = Σ(xP(x)), where E(x) is the expected value, x is the possible outcome, and P(x) is the probability of that outcome.

For example, consider the probability distribution of the number of heads when a coin is flipped three times. The possible outcomes are 0, 1, 2, and 3 heads, with probabilities of 1/8, 3/8, 3/8, and 1/8, respectively. The expected value can be computed as E(x) = (0*1/8) + (1*3/8) + (2*3/8) + (3*1/8) = 1.5.

Therefore, the expected value of the distribution is 1.5, which means that if the experiment of flipping a coin three times is repeated many times, the long-term average number of heads observed will be 1.5.

The sample mean of the weights at the birth of the randomly chosen infants is 7.6 pounds.

Given: The sample of seven infants was selected randomly and the weights are: {9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6} (in pounds)

What is a sample?

A sample can be defined as a part of something big or a whole. It can be some of the elements from a given set of elements.

For example: Let us consider the set of natural numbers. The set of natural numbers has an infinite number of elements in it. We choose some numbers from the set, say {2, 7, 9, 10, 99, 200, 234}. These chosen numbers are known as samples from the set of natural numbers.

What is the sample mean?

The sample mean is the average value of the samples or it is the mean of all the elements which exist in the given sample.

The sample mean is denoted by x⁻ which is pronounced as x bar.

The formula to calculate sample mean (x⁻) is:

Sample Mean (x⁻) = Summation of all the elements in the sample / Total number of elements in the sample.

x⁻ = ∑xₙ / n

where,

∑xₙ = Summation of all the elements in the sample

n = Total number of elements in the sample

x⁻ = Sample mean

Now let's solve the given question:

The given sample is {9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6}

The summation of the elements in the sample is:

∑xₙ = 9.0 + 7.3 + 6.0 + 8.8 + 6.8 + 8.4 + 6.6

∑xₙ = 52.9

The total number of elements in the sample is:

n = 7

Therefore, the sample mean (x⁻) is:

x⁻ = ∑xₙ / n

x⁻ = 52.9 / 7

x⁻ = 7.5571 ≈ 7.6

Hence the sample mean of the weights at the birth of the randomly chosen infants is 7.6 pounds.

Answer:

1/237.12.

Step-by-step explanation:

The probability of winning the minimum award can be calculated by multiplying the probability of picking 4 numbers correctly from 1 to 51 and then multiplying by the probability of picking 1 number correctly from 1 to 42.

The probability of picking 4 numbers correctly from 1 to 51 is given by the formula:

(number of combinations of 4 numbers from 51) / (number of combinations of 5 numbers from 51)

= (51 choose 4) / (51 choose 5)

= 51! / (4! * 47!) / (51! / (5! * 46!))

= (51 * 50 * 49 * 48) / (5 * 4 * 47 * 46)

= 19600 / 10,946

= 1/5.6 approximately

The probability of picking 1 number correctly from 1 to 42 is given by the formula:

1/42

The final probability of winning the minimum award is given by multiplying the above two probabilities:

1/5.6 * 1/42 = 1/237.12

So, the probability of winning the minimum award is approximately 1/237.12.
