Answer:

Mean score of 90 students = 77.2

Step-by-step explanation:

Mean score of 50 students from school A = 75

Mean score of 40 students from school B = 80

We need to find mean score of the 90 students?

First we will find sum of scores of students from school A

We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]

We have Average = 75, Number of terms = 50, We need to find Sum of terms (scores)

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\75=\frac{Sum\:of\:Terms}{50}\\Sum\:of\:Terms= 75\times 50\\Sum\:of\:Terms=3750[/tex]

So, Sum of scores for School A = 3750

Now, we will find sum of scores of students from school B

We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]

We have Average = 80, Number of terms = 40, We need to find Sum of terms (scores)

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\80=\frac{Sum\:of\:Terms}{40}\\Sum\:of\:Terms= 80\times 40\\Sum\:of\:Terms=3200[/tex]

So, Sum of scores for School B = 3200

Now, We will find mean score of the 90 students?

Mean score of 90 students will be:

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\Average=\frac{3750+3200}{90}\\Average=\frac{6950}{90}\\Average = 77.2[/tex]

So, mean score of 90 students = 77.2

Example for Table 1:

y = x + 6

So if X=-8

1st Row -8+6=-2

2nd Row -4+6=2

3rd Row -2+ 6=4

4th Row -9+6=-3

5th Row 2+6=8

So for any table, the X in the table rule is the X that you are working on.

Step-by-step explanation:

Answer:

y= 0,4 x=0,3

Step-by-step explanation:

We defined an argument as a reasoned or thoughtful process. The correct option is A.

An argument is a statement or set of claims known as premises that are designed to assess the degree of truth or acceptability of another statement known as the conclusion. Arguments may be analyzed from three different perspectives: logical, dialectical, and rhetorical.

Since the act or process of arguing, reasoning, or discussing is known as an argument. Therefore, we defined an argument as a reasoned or thoughtful process.

An argument is made up of three parts: the conclusion, the premises, and the assumptions. 

The conclusion (or theses) is the point of the argument's major idea—what the author is attempting to show.

The premises are the reasoning or evidence provided by the author to justify the conclusion.

The assumptions support the conclusion, but unlike the premises, they are unsaid and so invisible.

They connect the premises and conclusions.

Answer:

1. x= 11+-27

2.x = 7.5 + -1y

Step-by-step explanation:

1. Move all terms containing x to the left, all other terms to the right.

Add '-4y' to each side of the equation.

2x + 4y + -4y = 22 + -4y

Combine like terms: 4y + -4y = 0

2x + 0 = 22 + -4y

2x = 22 + -4y

Divide each side by '2'.

x = 11 + -2y

Simplifying

x = 11 + -2y

2.Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

2x + 2y + -2y = 15 + -2y

Combine like terms: 2y + -2y = 0

2x + 0 = 15 + -2y

2x = 15 + -2y

Divide each side by '2'.

x = 7.5 + -1y

Simplifying

x = 7.5 + -1y

22°+68°=90° ......

Answer:

m∠RSQ = 19°

Step-by-step explanation:

From the picture attached,

RT is the diameter of the a circle.

Angle subtended at the circumference by the diameter of a circle = 90°

Therefore, m∠RST = 90°

Since, m∠RSQ + m∠QST = m∠RST

m∠RSQ + 71° = 90°

m∠RSQ = 90° - 71°

             = 19°

Therefore, measure of angle RSQ is 19°.

Answer:

3x+7

Step-by-step explanation:

Use long division or synthetic division. (3x^2+13x+14)/(x+2)

The length of the rectangular garden is 3x + 7

The given expression:

[tex]A = 3x^2 + 13x + 14[/tex]

the width of the garden = x + 2

let the length of the garden = y

To find:

The area of the rectangular garden is calculated as;

[tex]A = y(x + 2) = 3x^2 + 13x + 14\\\\y(x + 2) = 3x^2 + 13x + 14\\\\y = \frac{3x^2 + 13x + 14}{x + 2}[/tex]

Using long division method:

                         3x + 7

                    ------------------------------

        x + 2 √ 3x² + 13x + 14

                  - (3x² + 6x)

                   -------------------------

                              7x + 14

                            - (7x + 14)

                  -------------------------------

                                0

Thus, the length of the rectangular garden, y = 3x + 7

Answer:

x = 6

Step-by-step explanation:

Alternate angles are congruent.

7x - 9 = 3x + 15               {Subtract 3x form both sides}

7x - 3x -9 = 15

      4x - 9=15            {Add 9 to both sides}

           4x = 15+9

           4x = 24

           x = 24/4
