In multinomial logistic regression, the dependent variable is categorical with three or more levels, and there must be more than one nominal predictor variable. The correct option is B.

This means that there is more than one predictor variable, but not necessarily all predictors must be log-transformed. The analysis aims to model the relationship between the categorical outcome variable and the predictor variables. The model estimates the probability of each outcome category relative to a reference category, with each predictor variable having its own set of regression coefficients. The output of the analysis includes estimates of the regression coefficients and their standard errors, as well as the odds ratios associated with each predictor variable.

Therefore, multinomial logistic regression is a powerful tool for examining the relationship between categorical variables and multiple predictor variables, and can provide important insights into the factors that contribute to different outcomes.

Answer: A

Step-by-step explanation:

Because the terms that are being multiplied have the same base (3) you would simply add the exponents and then make that the exponent of 3.

Add exponents 2/5+-7/5= -5/5 = -1

So that would be 3^-1

Whenever you have a negative exponent, you move it to the bottom to make it positive:

1/(3^1) which is just 1/3 or A

Answer:

1/3

Step-by-step explanation:

Three things to know to do this problem:

To multiply numbers with the same base, add the exponents. See image.

To add fractions with the same denominator (bottom number), keep the bottom number and add the top numbers.

See image.

To "fix" a negative exponent (make it a positive exponent), "push" the whole thing (base and exponent) across a fraction bar. See image.

The common difference in the arithmetic sequence is d = 6 (each term increases by 6 compared to the previous term). The first term is a_1 = 7.

To write the sum of the first 51 terms using sigma notation with the lower limit n=2, we need to find the upper limit of the summation. We can use the formula for the nth term of an arithmetic sequence:

a_n = a_1 + (n-1)d

Setting a_n equal to the last term we want to include in the sum (which is the 51st term), we get:

a_51 = 7 + (51-1)6 = 307

So the upper limit of the summation is n = 51.

Now we can use sigma notation to write the sum of the first 51 terms:

∑(n=2 to 51) (7 + (n-1)6)

This notation means that we start the summation from n = 2 and add up the terms in the sequence for n = 2, 3, 4, ..., 51. The term inside the parentheses represents each term in the sequence, which is 7 plus the common difference multiplied by (n-1).

To evaluate this summation, we can simplify the expression inside the parentheses:

7 + (n-1)6 = 6n + 1

Now we can substitute this expression back into the sigma notation:

∑(n=2 to 51) (6n + 1)

Expanding the summation, we get:

(6(2) + 1) + (6(3) + 1) + (6(4) + 1) + ... + (6(51) + 1)

Simplifying, we get:

13 + 19 + 25 + ... + 307

To find the sum of this arithmetic series, we can use the formula:

S_n = (n/2)(a_1 + a_n)

where S_n is the sum of the first n terms, a_1 is the first term, and a_n is the nth term.

Plugging in the values, we get:

S_51 = (51/2)(7 + 307) = 7863

Therefore, the sum of the first 51 terms of the arithmetic sequence is 7863.

Equation:

In mathematics, an equation is an expression that indicates equality of two expressions by connecting them with the equal sign = . The word "equation" and related words in other languages ​​can have slightly different meanings. For example, in French an equation is defined as containing one or more variables, whereas in English a well-formed formula consisting of two expressions connected by an equal sign is an equation.

Given:

This table;

x             y = 3x+3

-3                -6

-2                 a

-1                  b

0                 3

1                  c

2                 d

To Find:

Values of a, b, c and d

Consider the 2nd row,

x = -2, y = a

Putting the values in the equation,

we get,

   a = 3(-2) + 3

⇒ a = -3

Consider the 3rd row,

x = -1, y = b

   b = 3(-1) + 3

⇒ b = 0

Consider the 5th row,

x = 1, y = c

Putting the values in the equation,

   c = 3(1) + 3

⇒ c = 6

Consider the 6th row,

x = 2, y = d

   d = 3(2) + 3

⇒ d = 9

\(\large\underline{\sf{Solution-}}\)

Given that,

In triangle ABC

\( \purple{\rm :\longmapsto\:\angle A + \angle B = 125 \degree \: - - - (1) }\)

\( \purple{\rm :\longmapsto\:\angle B + \angle C = 150 \degree \: - - - (2)}\)

We know,

Sum of all interior angles of a triangle is supplementary.

\( \purple{\rm :\longmapsto\:\angle A + \angle B + \angle C = 180\degree }\)

On adding equation (1) and (2), we get

\( \purple{\rm :\longmapsto\:\angle A + \angle B + \angle B + \angle C = 125\degree + 150 \degree \:}\)

\( \purple{\rm :\longmapsto\:\angle A + \angle B + \angle C + \angle B = 275\degree \:}\)

\( \purple{\rm :\longmapsto\:180\degree + \angle B = 275\degree \:}\)

\( \purple{\rm :\longmapsto\:\angle B = 275\degree - 180\degree \:}\)

\( \purple{\rm :\longmapsto\:\angle B = 95\degree \:}\)

On substituting the value in equation (1) and (2), we get

\( \purple{\rm :\longmapsto\:\angle A + 95\degree = 125\degree }\)

\( \purple{\rm :\longmapsto\:\angle A = 125\degree - 95\degree }\)

\( \purple{\rm :\longmapsto\:\angle A = 30\degree }\)

Also, from equation (2), we get

\( \purple{\rm :\longmapsto\:95\degree + \angle C = 150\degree }\)

\( \purple{\rm :\longmapsto\:\angle C = 150\degree - 95\degree }\)

\( \purple{\rm :\longmapsto\:\angle C = 55\degree }\)

Hence,

\(\begin{gathered}\begin{gathered}\bf\: \rm\implies \:\begin{cases} &\sf{\angle A = 30\degree } \\ \\ &\sf{\angle B = 95\degree } \\ \\ &\sf{\angle C = 55\degree } \end{cases}\end{gathered}\end{gathered}\)

A multiple-choice question with 8 answer choices can be displayed to each student in random order in 40320 different ways.

When answer choices are displayed in random order to each student, the order in which the choices are presented becomes an important factor in determining the number of possible combinations. In this case, each choice has 8 possible positions, so the first choice can be presented in 8 different ways. Once the first choice has been assigned, the second choice has 7 remaining positions, and so on, down to the last choice which has only one possible position.

To calculate the total number of possible combinations, we use the concept of factorial. Factorial is a mathematical operation that returns the product of all positive integers up to a given number. In this case, 8! is calculated as follows:

8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320

Therefore, there are 40320 different ways in which the question with 8 answer choices can be displayed to each student in random order.

In a finite group G, if a is an element of G with order o(a) = n, then we need to show that the order of the inverse of a, denoted as o(a^(-1)), is also equal to n.

To prove that o(a^(-1)) = n, we need to show that raising a^(-1) to the power of n gives us the identity element of the group, denoted as e.

Since a has order n, we know that a^n = e, where e is the identity element of the group.

Taking the inverse of both sides of this equation, we have (a^n)^(-1) = e^(-1).

Applying the property of inverses, we get a^(-n) = e.

Now, consider the element a^(-1). If we raise it to the power of n, we have (a^(-1))^n = (a^(-n)) = e.

This shows that the order of a^(-1) is n, as raising it to the power of n gives us the identity element e.

Hence, we have proved that o(a^(-1)) = n, which means that the order of the inverse of a is equal to the order of a in the finite group G.

The function that best models the number of game systems sold  is

y = 30.5(0.7)ˣ

What is the solution to an equation?

In order to make the equation's equality true, the unknown variables must be given values as a solution. In other words, the definition of a solution is a value or set of values (one for each unknown) that, when used as a replacement for the unknowns, transforms the equation into equality.

Consider the equation :

y = 30.5(0.7)ˣ

Plug in x=0,

y= 30.5(0.7)⁰ = 30.5 *1 = 30.5

The point is (0,30.5)

Similarly, when we plug in x=1 and x=2, we get y=21.35 and y=14.95 respectively

The other 2 points in (x, y) form are (1,21.35) and (2, 14.95)
