Answer:

I only

Step-by-step explanation:

any point and its coordinates is an ordered pair of (x, y).

in other words, we get the x value used for the function and the resulting y value.

if the equation is true for such a pair, then the point is on the line. if it is false, then not.

y = (-5/4)x + 5

(4, 0)

0 = (-5/4)×4 + 5 = -5 + 5 = 0

true.

(0, 5)

5 = (-5/4)×0 + 5 = 0 + 5 = 5

true.

y + 5 = (-5/4)(x - 4)

(4, 0)

0 + 5 = (-5/4)(4 - 4)

5 = (-5/4)×0 = 0

false.

so, II is not containing (4, 0).

therefore, only I is contains both points.

The answer is c. Chi-square test. A Chi-square test is an inferential statistical technique used to analyze the relationship between two categorical variables organized in a bivariate table.

In a chi-square test, the data is organized into a contingency table, also known as a cross tabulation or bivariate tabulation. This table displays the frequency distribution of two categorical variables, showing how they are related or associated with each other.

The chi-square test evaluates whether there is a significant relationship or association between the variables. It calculates a test statistic based on the observed frequencies in the contingency table and compares it to the expected frequencies under the assumption of independence between the variables. If the test statistic is sufficiently large, it indicates that there is a significant relationship between the variables, rejecting the null hypothesis of independence.

The chi-square test is widely used in various fields, including social sciences, market research, and epidemiology, to determine if there is a significant association between categorical variables. It provides valuable insights into the relationship between variables and helps researchers make informed conclusions based on their data.

Answer:

897  3/4 m^3

Step-by-step explanation:

V = l*w*h

V = 19 * 13 1/2 * 3 1/2

Change the mixed number to improper fractions

V = 19 * 27/2 * 7/2

V =3591/4

Now change the improper fraction back to a mixed number

V = 897  3/4 m^3

The coefficient of \(x^{2}\) in \((2x^{2}-3x-4)-(5x^{2}+6x-7)\) is -3.

A coefficient is a multiplicative factor in a polynomial, series, or expression in mathematics. It is typically a number, although it can also be any expression (including variables such as a, b and c). They may also be referred to as parameters if the coefficients are variables in and of themselves. The coefficient in an expression that is not related to any variables is called the constant coefficient (also known as constant term or free coefficient).

Given equation,

\((2x^{2}-3x-4)-(5x^{2}+6x-7)\)

= \(2x^{2}-3x-4-5x^{2}-6x+7\)

= \(-3x^{2}-9x+3\)

Hence, coefficient of \(x^{2}\) is -3.

The value of the given algebraic expression is 7. The solution has been obtained by using arithmetic operations.

A mathematical expression called an algebraic expression can have variables or integers in it. It cannot be solved because it lacks an equals sign. A sequence of algebraic expressions are separated by an equals sign and are part of an algebraic equation, which can be solved.

We are given an algebraic expression as (f + g)/j.

The values of f = 6, g = 8, h = 12 and j = 2.

On substituting these in the expression, we get

⇒(6 + 8)/2

⇒14/2

Solution:

From the question;

Let c = Combo Meal (with fries) - $5.25

s = Soda - $2.00

i = Iced Tea - $2.25

The family ordered 3 combo meals, 2 sodas and 1 iced tea

So, expressing it;

Bill = 3c + 2s + i

Substituting the prices for the meals

Bill = 3(5.25) + 2(2) + 2.25

Bill = 15.75 + 4 + 2.25

Bill = $22

Answer:

6 thirds

Step-by-step explanation:

The total number of games the team played last year was 80 (option C). In the first half of the year, the team won 60 percent of their games, indicating that they won 6 out of every 10 games played.

In the second half of the year, the team played 20 games and won 3 of them. This means that in the second half, they won only 3 out of 20 games, which is equivalent to winning 15 percent of their games.

To find the overall percentage of games won, we can calculate the weighted average of the two percentages. Since the team won 50 percent of their games overall, we can assign equal weights to the first and second halves of the year. Therefore, the average winning percentage for the team would be the midpoint between 60 percent and 15 percent, which is (60% + 15%) / 2 = 37.5%.

Let's assume the total number of games played last year was x. Since the team won 37.5% of the games, they won 0.375x games. We can set up an equation based on the information given:

0.375x = 50% of x

0.375x = 0.5x

0.5x - 0.375x = 0

0.125x = 0

x = 0 / 0.125

x = 0

Step-by-step explanation:

The number of guest satisfaction surveys will you need to send out to make certain you receive at least 300 surveys back is 1,250.

Since the return is received i.e. 24%

And, there are the minimum of 300 surveys

So, based on this, the no of guest satisfaction should be

\(= 300 \div 0.24\)

= 1,750

The relation is a function because it is a one-to-one relation

The relation is given as

y = -3x

The inputs are given as

x = 0, x = 1 and x = 2

Substitute the values of x i.e. x = 0, x = 1 and x = 2 in the equation of the function y = -3x

So, we have

y = -3(0) = 0

y = -3(1) = -3

y = -3(2) = -6
