The payoff matrix that Gabriel and Nia use demonstrates the zero-sum between two players by showing each person's earnings as a function of both of their choices.

The reward matrix or payoff matrix is a double-entry table, similar to another Table, that holds all of the payments made by one player to the other for each selected strategy. Since one player's payment equals the other player's gain, the game is referred to as zero-sum.

The example case scenario can be used to demonstrate the calculation in the payout matrix above;

If the row player has n strategies and the column player has m strategies, the matrix must have n & m cells and contain a total of 2 n m reward values. The row player's name appears in a payment matrix to the left of the matrix, while the column player's name appears above the matrix.

If other factors are held constant, sets of data that would produce the largest value for an independent-measures t statistic is the two samples both have n =30, with sample variances of 20 and 25

In a T test, the T statistic is used to help you decide whether to accept or reject the null hypothesis.

You utilize it in a manner that is quite similar to using a Z-score. When you don't know the population standard deviation or have a limited sample size, you use the t statistic.

You employ the T statistic with a p value while performing a hypothesis test. Your results' likelihood of being the result of chance is indicated by the p-value. Typically, in statistics, you use a T Test with a T Statistic rather than a Z score because you don't know much about the population.

The inverse cosine function to find the measures of the = arccos(-sqrt)

What is measure of angles?

Angle measure can be defined as the measure of the angle formed by the two rays or arms at a common vertex.

To find the measures of the angles of a triangle, you can use the Law of Cosines, which states that the square of the length of a side of a triangle is equal to the sum of the squares of the lengths of the other two sides minus twice the product of the lengths of the other two sides and the cosine of the angle opposite the side in question.

In this case, we are given the coordinates of the vertices of the triangle and we want to find the measures of the angles. To do this, we can use the distance formula to find the lengths of the sides of the triangle and then use the Law of Cosines to find the cosines of the angles.

The distance formula is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2)
where d is the distance between the two points with coordinates (x1, y1, z1) and (x2, y2, z2).
Using this formula, we can find the lengths of the sides of the triangle as follows:
PR = sqrt((4 - 1)^2 + (0 - 2)^2 + (2 - 3)^2) = sqrt(9 + 4 + 1) = sqrt(14)
PQ = sqrt((3 - 1)^2 + (4 - 2)^2 + (2 - 3)^2) = sqrt(4 + 4 + 1) = sqrt(9)
QR = sqrt((4 - 3)^2 + (0 - 4)^2 + (2 - 2)^2) = sqrt(1 + 16 + 0) = sqrt(17)
Now we can use the Law of Cosines to find the cosines of the angles:
cos A = (PR^2 + PQ^2 - QR^2) / (2 * PR * PQ)
= (14 + 9 - 17) / (2 * sqrt(14) * sqrt(9))
= (-4) / (2 * sqrt(14) * sqrt(9))
= -2 / (sqrt(14) * sqrt(9))

cos B = (QR^2 + PQ^2 - PR^2) / (2 * QR * PQ)
= (17 + 9 - 14) / (2 * sqrt(17) * sqrt(9))
= (2) / (2 * sqrt(17) * sqrt(9))
= 1 / (sqrt(17) * sqrt(9))

cos C = (QR^2 + PR^2 - PQ^2) / (2 * QR * PR)
= (17 + 14 - 9) / (2 * sqrt(17) * sqrt(14))
= (12) / (2 * sqrt(17) * sqrt(14))
= 6 / (sqrt(17) * sqrt(14))

Finally, we can use the inverse cosine function to find the measures of the angles:
A = arccos(-2 / (sqrt(14) * sqrt(9)))
= arccos(-2 / (2 * sqrt(7) * sqrt(3)))
= arccos(-1 / sqrt(7) * sqrt(3))
= arccos(-sqrt)

Standard Deviation

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

The name standard deviation for SD came from Karl Pearson. I would guess no more than that he wanted to recommend it as a standard measure. If anything, I guess that references to standardization either are independent or themselves allude to SD.

Mean

In statistics, the mean is one of the measures of central tendency, apart from the mode and median. Mean is nothing but the average of the given set of values. It denotes the equal distribution of values for a given data set. The mean, median and mode are the three commonly used measures of central tendency.

Normal Distribution

Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. In graphical form, the normal distribution appears as a bell curve.

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the number of pizzas be x₁ = 2

Let the cost of 2 pizzas be y₁ = $ 25

So , the first point A ( x₁ , y₁ ) = A ( 2 , 25 )

Now ,

Let the number of pizzas be x₂ = 5

Let the cost of 5 pizzas be y₂ = $ 58

So , the second point B ( x₂ , y₂ ) = B ( 5 , 58 )

Therefore , the slope of the 2 points is given by

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 58 - 25 ) / ( 5 - 2 )

Slope m = 33 / 3

Substitute the value of m in the equation , we get

y - 25 = 11 ( x - 2 )

y - 25 = 11x - 22

Adding 25 on both sides of the equation , we get

y = 11x + 3

So , the equation of line is y = 11x + 3

Now , the customer pays $ 80 , so to find the number of pizzas the customer gets can be calculated by substituting the value of y = 80

And ,

y = 11x + 3

80 = 11x + 3

Subtracting 3 on both sides of the equation , we get

11x = 77

Divide by 11 on both sides of the equation , we get

x = 7 pizzas

Therefore , the number of pizzas is 7 pizzas

Hence ,

The number of pizzas delivered to a customer who pays $ 80 is 7 pizzas

Although part of your question is missing, you might be referring to this full question: Which of the following statements regarding the expansion of (x + y)^n are correct?

By expanding the exponential expressions, the answers are option A, B, and D.

The exponential expressions: (x + y)^n

Which means that we multiply the polynomial (x + y) by itself n times.

Option A.

This statement is true, because there is only one x in the original polynomial, and we multiply it by itself n times, then we can have only one term equal to x^n (or y^n).

Option B.

This statement is true, because if we multiplicate the variables by themselves n times, then the degree of the term also has to be n. Since for a term: (x^a)*(y^b) the degree is a + b; then it always be a + b = n.

Option C.

This statement is false, because of the same reasons in Option B.

Option D.

This statement is true, because in the original polynomial the coefficients of y and x are the same, then in the expansion the coefficients of the reflected terms like (x^a)*(y^b) and (x^b)*(y^a) are equal.

From two populations, independent random samples were drawn, each having 80 observations. The test statistic should be z = 2.18 because samples from populations 1 and 2 yielded 33 and 28 successes, respectively.

P-value is set at 0.030.

State the null and alternate hypotheses in step one.

H0: (p1-p2) = 0

Ha: (p1-p2) ≠ 0

Step 2: Calculate the test statistic

We can calculate the test statistic using the formula:

z = (p1-p2)/√(p(1−p)(1/n1+1/n2))

where,

p = (successes in sample 1 + successes in sample 2)/(n1+n2)

= (33 + 28)/(80 + 80)

= 61/160

= 0.30

n1 = sample size of population 1

= 80

n2 = sample size of population 2

= 80

Therefore,

z = (p1-p2)/√(p(1−p)(1/n1+1/n2))

= (33/80 - 28/80)/√(0.38125(1−0.38125)(1/80+1/80))

=2.18
