Using combinatorics, there are 1926 ways to distribute 9 different computer games among Wendy, Jim, and Hannah so that each person receives an odd number of games.

If each person receives an odd number of games, then the number of games must be 1, 3, 5, or 7. There are four odd numbers to choose from.

We can use combinatorics to find the odd number in each turn.

Let's consider each odd number in turn.

If each person gets 1 game, then we are looking for the number of ways to choose 3 games out of 9 to distribute. This is simply the number of combinations of 3 things taken from a set of 9 things, which is 9C3, or (9!)/(3!6!) = 84.

If each person gets 3 games, then we are looking for the number of ways to choose 3 games out of 9 to distribute to one person. Once those games have been chosen, we are left with 6 games to distribute to the other two people. The number of ways to choose 3 games out of 9 is again 84, but we must multiply this by the number of ways to choose 3 games out of the remaining 6. This is 6C3, or (6!)/(3!3!) = 20. Therefore, the total number of ways to distribute 9 games with each person getting 3 games is 84*20 = 1680.

If each person gets 5 games, then we are looking for the number of ways to choose 5 games out of 9 to distribute to one person. Once those games have been chosen, we are left with 4 games to distribute to the other two people. The number of ways to choose 5 games out of 9 is 126, and the number of ways to choose 4 games out of the remaining 4 is 1. Therefore, the total number of ways to distribute 9 games with each person getting 5 games is 126*1 = 126.

If each person gets 7 games, then we are looking for the number of ways to choose 7 games out of 9 to distribute to one person. Once those games have been chosen, we are left with 2 games to distribute to the other two people. The number of ways to choose 7 games out of 9 is 36, and the number of ways to choose 2 games out of the remaining 2 is 1. Therefore, the total number of ways to distribute 9 games with each person getting 7 games is 36*1 = 36.

Adding up the number of ways to distribute the games in each case, we get 84 + 1680 + 126 + 36 = 1926.

Answer:

$-9125

Step-by-step explanation:

6.25÷100 = 0.0625                                    50×12=600

0.0625×250= $15.625

6.25%=$15.625

15.625×600= $9375

$250-$9375=  -9125

The account be worth at the end of the 50-year period will be 9125 dollar.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that savings account is opened with an initial deposit of $250, and interest is compounded monthly at 6.25% for 50 years.

The rate is 6.25÷100 = 0.0625                                    

Therefore, 50×12=600

0.0625×250= $15.625

Since we know that 6.25%=$15.625

15.625×600= $9375

Thus we get;

$250-$9375 = -9125

Hence, the account be worth at the end of the 50-year period will be 9125 dollar.

the equation is;

The answer is:

The value of the expression after evaluating it according to the values of c and d is 42.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Since, no expression is given, let us assume that the expression is

c + d / 4

Now we have to evaluate the value of the expression according to the values of c and d,

For that, we will simply put the given values in the expression and solved it accordingly,

Put c = 36 and d = 24 in the expression we assumed,

c + d / 4 = 36 + 24/4

= 36 + 6 = 42

Hence, the value of the expression after evaluating it according to the values of c and d is 42.

From the question, the first table is not a function while the other two tables are functions.

A function is a correspondence or mapping from a first set of numbers, called the domain of the function, to a second set of numbers, called the range of the function, such that for each member of the domain there is exactly one member of the range.

A function is said to be one-to-one if every y value has exactly one x value mapped onto it, and many-to-one if there are y values that have more than one x value mapped onto them. This graph shows a many-to-one function.

4) We see that all the y-values are the same or equal. Thus, we can say that it is not a function because it doesn't match the definition above.

Answer:

describing the data.

Step-by-step explanation:

It is required to find the third part of the process of investigating a question using data.

For comparing three treatments using a one-way fixed effects model, the required sample size (n) is 2.5088

we need to consider the desired power level, significance level, effect size (∆), and the variance (σ²). In this scenario, we want at least 80% power at the 5% significance level, with treatment means that differ by 100 - ∆, 100, and 100 + ∆, where ∆ = 5. The variance is given as σ² = 10.

To calculate the sample size, we can use power analysis based on the F-test. The formula for sample size in this case is:

n = 2 * [(Zα/2 + Zβ)² * σ²] / ∆²

where Zα/2 is the critical value for the desired significance level (5% or 0.05), and Zβ is the critical value for the desired power level (80% or 0.80).

Plugging in the values, we get:

n = 2 * [(1.96 + 0.84)² * 10] / 5²

n = 2 * [(2.80)² * 10] / 25

n = 2 * 7.84 * 10 / 25

n = 6.272 * 10 / 25

n = 2.5088

Rounding up to the nearest whole number, the required sample size (n) is 3.

Therefore, the sample size must be at least 3 in order to achieve at least 80% power at the 5% significance level for comparing the three treatments using a one-way fixed effects model.

Yes, this is true.

A normal distribution with a mean of 0 and a standard deviation of 1 is often denoted as N(0, 1) or n(0, 1). This distribution is also known as the standard normal distribution. It is a symmetric bell-shaped distribution where the majority of the data falls within approximately three standard deviations from the mean.

The standard normal distribution, denoted as N(0, 1) or n(0, 1), is a specific type of normal distribution that has a mean of 0 and a standard deviation of 1. It is often used as a benchmark for comparing and standardizing data in statistical analysis.

The shape of the standard normal distribution is symmetric and bell-shaped. It follows the familiar "bell curve" pattern, where the data is concentrated around the mean and gradually tails off towards the extremes. The total area under the curve is equal to 1, representing the entire probability space.

The standard deviation of 1 indicates the spread or variability of the data. In a standard normal distribution, about 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations, and roughly 99.7% falls within three standard deviations.

The standard normal distribution is widely used in statistical calculations and hypothesis testing. It serves as a reference distribution for many statistical methods, such as z-tests and z-scores. By converting data from other normal distributions into standard units using z-scores, researchers can compare and analyze data from different distributions on a common scale.

The standard normal distribution also has specific properties that make it mathematically tractable. The cumulative distribution function (CDF) of the standard normal distribution, often denoted as Φ(z), gives the probability that a standard normal random variable is less than or equal to a given value z. This CDF is tabulated in standard statistical tables or can be calculated using mathematical functions.

Overall, the standard normal distribution is a fundamental concept in statistics, providing a reference distribution for comparing and analyzing data and serving as a basis for many statistical techniques and calculations.

Step-by-step explanation:

The midpoint between two points A(0,0) and B(8,4) is (4,2)

The distance between two points A(0,0) and B(8,4) is 4√5

To find the midpoint of two points,

We need to take an average of both the x and y components of both points

Two points A(x ₁,y₁) and B(x₂ ,y₂) are (0,0) and (8,4) respectively

Let M be the mid-point M(x, y),

x = x₁+x₂/2

 = 0+8/2

= 8/2

= 4

Similarly

y = y₁+y₂/2

  = 0+4/2

  = 4/2

  = 2

So, the midpoint of the two points A(0,0) and B(8,4) is (4,2)

To find the distance between two points,

We need to take the square root of the difference square of x and y, which is

d² = Δx² + Δy²

d = √(Δx²+Δy²)

Δx = x₂-x₁

    = 8-0

   = 8

Δy = y₂-y₁

    = 4-0

    = 4

Thus,

d = √(8²+4²)

d = √(64 + 16)  

d = √80

d = 4√5

So the distance between the two points is 4√5

The slope-intercept form is written as:

y = mx + b

So, we need to rewrite the given equation in this form:

x - y = 10

x - y - x = 10 - x

-y = 10 - x

(-1) * (-y) = (-1) * (10 - x)

y = -10 + x

y = x - 10

Now, we can graph the equation. In order to do so, we can plot two points that satisfy this equation and join them with a line.

Notice that, for x = 0:

y = 0 - 10 = -10

For x = 10:

y = 10 - 10 = 0
