                 The width of each interval is calculated as:

                       i.e.   (22-7)/4=15/4=3.75≈4

We know that for classifying a class interval in a histogram the width of each of the interval must be equal.

A) 7−11; 11−14; 15−19; 20−22

In option: A--

the width of first interval is: 4

width of second interval is: 3

Width of third interval is: 4

Width of fourth interval is: 2

Hence, the width of each interval is not equal.

Hence, option: A is discarded.

In option: C--

the width of first interval is: 3

width of second interval is: 5

Width of third interval is: 4

Width of fourth interval is: 3

Hence, the width of each interval is not equal.

Hence, option: C is discarded.

D)  7−13; 15−19; 20−22

In option: D--

the width of first interval is: 6

width of second interval is: 4

Width of third interval is: 2

Hence, the width of each interval is not equal.

Hence, option: D is discarded.

B)  7−10; 11−14; 15−18; 19−22

There are a total of 4 intervals and also width of each interval is equal and equal to 4.

Answer:

centre = (2, - 1), radius = 6

Step-by-step explanation:

Rearrange the equation by placing the x and y terms together and adding 31 to both sides

Given

x² + y² - 4x + 2y - 31 = 0, then

x² - 4x + y² + 2y = 31

Use the method of completing the square

add ( half the coefficient of the x/y term )² to both sides

x² + 2(- 2)x + 4 + y² + 2(1)y + 1 = 31 + 4 + 1

(x - 2)² + (y + 1)² = 36

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r the radius

compare to (x - 2)² + (y + 1)² = 36, then

centre = (2, - 1) and r = [tex]\sqrt{36}[/tex] = 6

The center of the circle is  (2, - 1) and the radius is 6 units.

The equation for a circle has the generic form x² + y² + 2gx + 2fy + c = 0.

The standard equation of a circle is x² + y² = r².

The polar form of the equation of the circle is (rcosθ)² + (rsinθ)² = p².

Given, The equation of a circle is x² + y² - 4x + 2y - 31 = 0.

We know, In x² + y² + 2gx + 2fy + c = 0, The center of the circle is,

(- g, - f) and radius is [tex]\sqrt{g^2 + f^2 - c[/tex].

Therefore, 2gx = - 4x and 2fy = 2y.

2g = - 4 and 2f = 2.

g = - 2 and f = 1.

- g = 2 and - f = - 1.

So, The center is (2, - 1).

And the radius is, [tex]\sqrt{2^2 + -1^2 + 31[/tex].

= [tex]\sqrt{4 + 1 + 31[/tex].

= [tex]\sqrt{36[/tex].

= 6 units.

* hope you understand*

The volume of a rectangular solid where width equals a cm, length equals twice the width, and the height is twice the length is calculated to be 8a³ cubic cm.

Based on the question, we know that the width of the rectangular solid is a cm. Where the length equals twice the width, so it is 2a cm; likewise, the height, which is twice the length, turns out to be 4a cm. The equation for calculating the volume of a rectangular solid is width * length * height. Therefore, if we substitute the given values, we have a cm * 2a cm * 4a cm, which equals 8a³ cubic cm.

It is given that:

The current (I) in an electrical conductor varies inversely as the resistance (R) of the conductor.

This means that:

[tex]A=(2x^{2}+9x-18)\ m^{2}[/tex]

Step-by-step explanation:

Let

L-----> the length of the concert hall

W----> the width of the concert hall

we know that

The area of a rectangle ( concert hall) is equal to

[tex]A=LW[/tex]

we have

[tex]L=(x+6)\ m[/tex]

[tex]W=(2x-3)\ m[/tex]

substitute the values

[tex]A=(x+6)(2x-3)\\ \\A=2x^{2} -3x+12x-18\\ \\A=(2x^{2}+9x-18)\ m^{2}[/tex]

The area of the concert hall's floor, in square meters, is represented by the simplified algebraic expression 2x² + 9x - 18, which is derived by multiplying the hall's length (x + 6) by its width (2x - 3) then simplifying the resulting expression.

The area of a rectangle is calculated by multiplying the length by the width. In this case, the length of the concert hall is given as (x + 6) meters and the width as (2x - 3) meters. Therefore, the area of the concert hall's floor, expressed in square meters, is the product of these two expressions.

So, you multiply (x + 6) by (2x - 3) to get the area, which gives you the following expression: 2x² - 3x + 12x - 18. Now, simplify this expression by combining like terms.

The simplified expression for the area of the floor in square meters is then 2x² + 9x - 18.

The question in this problem is:

The sum of 2 consecutive integers is at most the difference between nine times the smaller and 5 times the larger. What are the numbers?

First of all, let's name the first variable [tex]x[/tex] which is the smaller number. Accordingly, the lager number will be [tex]x+1[/tex] given that those numbers are consecutive. On the other hand at most conveys the idea of an inequality, which is:

[tex]\leq \\ which \ means \ less \ than[/tex]

So:

1. The sum of 2 consecutive integers can be written as:

[tex]v+(v+1)[/tex]

2. Nine times the smaller and 5 times the larger can be written as:

[tex]9v-5(v+1)[/tex]

Answer:

Option: B is the correct answer.      

B)     Decay, y- intercept = 3.4, rate is 34%

Step-by-step explanation:

We are given an exponential equation as follows:

                    [tex]y=3.4(0.66)^x[/tex]

We know that any exponential function of the type:

                                [tex]y=ab^x[/tex]

is growth function if: b>1

and is a decay function if 0< b< 1

Hence, here we have: b=0.66<1

Hence, the function is a decay function.

Also, we know that the y-intercept of a function is the point where x=0

Hence, we take x=0

we have:  [tex]y=3.4\times (0.66)^0\\\\\\y=3.4[/tex]

Hence, the y-intercept is:   3.4

Also, the rate of a function is denoted by 'r'

where b=1-r

    ⇒ 0.66=1-r

   ⇒   r=1-0.66

    ⇒ r=0.34

Hence, the rate is: 34%

          option: B is the correct answer.

Answer: p(x) = a (x-b)(x-c)(x-d)

Step-by-step explanation:

The first step is to determine the degree of the polynomial.

It shall depend totally on the linear factors given for the polynomial.

If there is one, it is a linear polynomial.

If there are 2, then it is a quadratic polynomial.

If there are three then it shall be a cubic polynomial.

Now let us assume that there are three linear factors.

We multiply those factors and write the polynomial.

If x-b, x-c & x-d are the factors we write

p(x) = (x-b)(x-c)(x-d)

But as we may have a leading coefficient so we write the polynomial as

Then we go on to expand this to get the polynomial in the standard form.

Answer with Step-by-step explanation:

First we find the degree of polynomial.

Consider two linear factors

(x-a) and (x-b)

Multiplying these two factors to get the polynomial.

[tex]p(x)=(x-a)(x-b)=x^2-(a+b)x+ab[/tex]

There are two linear factors .

Therefore, the degree of polynomial is 2 and the polynomial is quadratic.

Degree of polynomial=Number of linear factors

If the linear factors are three then the polynomial formed by multiplying theses factors .

Then, we get the polynomial of degree 3 and the polynomial is cubic polynomial.

It we have four linear factors.

After multiplying these four factors, we get a polynomial of degree 4.

The polynomial is bi quadratic.

Here the values of x can be less than -3 or the values of x can be greater than 4. Since 5 is greater than 4 so, 5 is included in the solution

2. {x:x ≥5}

Here the values of x can be greater than or equal to 5. So, 5 is included in the solution.

3. {x:x <5}

Here the values of x can be less than 5. So, 5 is not included in the solution

4. {x:0<x<4}

Here the value of x is greater than 0 but less than 4. So, 5 is not included in the solution

So, Option 1 and 2 are correct.

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (- 5, 4) with x- coordinate - 5, thus
