Answer:

x = 0

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

5x - 8(1 + 7x) = -8

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it is a solution.

Here we see that -8 does indeed equal -8.

∴ x = 0 is a solution of the equation.

Given:

Two diameters intersect each other.

To find:

The correct statement regarding two adjacent arcs created by two  intersecting diameters.

Solution:

We know that, two diameter intersect each other at origin and measure of arc is equal to the corresponding angle generated by the intersection of diameters.

If two lines intersect each other then we get 4 angles and sum of any two adjacent angles is 180°.

It means the sum of any two adjacent central angles generated by the intersection of diameters is 180°.

So, the sum of two adjacent arcs created by two  intersecting diameters is 180°.

Therefore, the correct option is C.

Answer:

Correct choice: a. k = 13.5; xy = 13.5

Step-by-step explanation:

Inverse Proportion

Two variables x and y are in inverse proportion or variation if:

[tex]\displaystyle y=\frac{k}{x}[/tex]

Where k is the constant of proportionality

Since we know that y=4.5 when x=3:

[tex]\displaystyle 4.5=\frac{k}{3}[/tex]

Solving for k:

[tex]k = 4.5*3 = 13.5[/tex]

Thus the equation is:

[tex]\displaystyle y=\frac{13.5}{x}[/tex]

Or, equivalently:

[tex]xy = 13.5[/tex]

Correct choice: a. k = 13.5; xy = 13.5

Answer:

∠D = 60

∠E = 99; x = 4

x = 32

Step-by-step explanation:

First things first, the sum of angles in a quadrilateral is 360°.

∠D + 120 + 95 + 85 = 360

∠D = 360 - 120 - 95 - 85

∠D = 60

∠E + 86 + 100 + 75 = 360

∠E = 360 - 86 - 100 - 75

∠E = 99

24x + 3 = 99

24x = 99 - 3

      = 96

x = 96 ÷ 24

x = 4

89 + 5x - 8 + 51 + 3x + 4 = 360

7x + 136 = 360

7x = 360 - 136

    = 224

x = 224 ÷ 7

x = 32

Answer:

Step-by-step explanation:

3x + 5y = 7

Since that is our original form, let's convert it so that we can find the slope:

5y = -3x + 7

y = -3/5 x + y

To get a perpendicular line, we need the negative reciprocal of the slope. This means that the sign switches and numerator and denominator flip:

m = 5/3

From here, we use the point-slope equation and then convert that into slope-intercept form:

y - y1 = m(x - x1)

y - 6 = 5/3(x - 0)

y - 6 = 5/3x

Answer:

The pair that performs second are Orville and Nancy.

Step-by-step explanation:

Since Jack and Leslie are partners and that they appear before Kelly, it is safe to assume that this pair may come first beforehand in which Orville also comes on before Kelly.  Nancy also appears before Leslie and since each pair has a female and a male, it is safe to assume that Orville and Nancy perform second while Jack and Leslie perform first and Kelly and Marty perform last.

Answer:

apothem: a line segment drawn from the center of a convex polygon (inscribed in a circle) to the midpoint of any side of the polygon.

regular polygon:a convex polygon in which all of the side lengths are equal and all of the interior angles have equal measure.

inscribed polygon:a polygon that is constructed inside of the circumference of a circle in which the vertices of the polygon lie on the circumference of the circle.

Step-by-step explanation:

The words that matched with the correct definition are given below.

The apothem is the angle between a chord's middle and the circle's center. The apothem of a regular polygon is only the in radius, or the distance from the center to a side.

The correct definitions are:

Apothem : a line segment drawn from the center of a convex polygon (inscribed in a circle) to the midpoint of any side of the polygon.

Regular polygon : a convex polygon in which all the side lengths are equal and all the interior angles have equal measure.

Inscribed polygon : a polygon that is constructed inside the circumference of a circle, in which the vertices of the polygon lie on the circumference of the circle.

Therefore, the correct definitions are given above.

Step-by-step explanation:

Lets look at our answer choices; A.

The intervals are not comparable. The shorter bar spans more than 10 years. When it comes to a horizontal axis it doesn't matter how far it expands,just if it's expanded correctly.

B.The intervals are appropriately labeled. There not it goes from 25 to 50 in just in instant few climbs up.

C.The intervals are not comparable, but the data on the graph is not misleading. It is misleading the graphs are incorrectly labeled.

Which brings us to our answer D.The vertical axis does not have an appropriate scale. it goes from 0-25 25-50 and 50-75 then 75-100. that's a short distance for such numbers that are pretty far apart.

Answer:

0.145

Step-by-step explanation:

Suppose λ = average number of an event occurring in an interval of a presented  length; &

x =  no. of events occurring in an interval length t

Thus, x has a Poisson distribution with parameter λt.

i.e.

[tex]P[X=k] = \dfrac{(\lambda t)^k\times e^{-\lambda t}}{k!} \ \ \ where; k = 0,1,2 ...[/tex]

Given that:

The average number of call every 8 hours = 11

Then, the parameter for the Poisson process [tex]\lambda =\dfrac{11}{8}[/tex]

where;

t = 2 hours

[tex]\lambda t = \dfrac{11}{8}\times 2[/tex]

[tex]\lambda t = \dfrac{11}{4}[/tex]

Also,

x = no. of calls occurring at an interval of length 2

The required probability is as follows:

P(x > 4) = 1 - [P ( x≤ 4) ]

[tex]=1 - [ P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) ][/tex]

[tex]= 1 - \bigg [ \dfrac{(\dfrac{11}{4})^0 \times e^{-11/4}}{0!}+\dfrac{(\dfrac{11}{4})^1 \times e^{-11/4}}{1!}+ \dfrac{(\dfrac{11}{4})^2 \times e^{-11/4}}{2!}+ \dfrac{(\dfrac{11}{4})^3 \times e^{-11/4}}{3!}+ \dfrac{(\dfrac{11}{4})^4 \times e^{-11/4}}{4!} \bigg ][/tex]

[tex]= 1 - \begin {bmatrix} 1 + \dfrac{11}{4} + \dfrac{\bigg (\dfrac{11}{4}\bigg)^2}{2}+\dfrac{\bigg (\dfrac{11}{4}\bigg)^3}{6}+\dfrac{\bigg (\dfrac{11}{4}\bigg)^4}{24} \end {bmatrix} e^{-11/4}[/tex]

[tex]= 1 - [ 1 + 2.75 + 3.78125 + 3.466145833 + 2.3829] \ e^{-11/4}[/tex]

= 1 - [13.38037]× 0.06393

Answer:

Explanation is written below.

Step-by-step explanation:

                                                1)

Given the line

[tex]y = -4x + 8[/tex]

Comparing with the slope-intercept form of the line equation

[tex]y=mx+b[/tex]    

Where m is the slope and b is the y-intercept

So, the slope of the line = m = -4

Thus, the equation of the line that is parallel to y = -4x + 8 and passes through the point (5, 1), using point slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]  

Here, m is the slope and (x₁, y₁) is the point

substituting the values m = -4 and the point (5, 1)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

y-1 = -4 (x - 5)

y-1 = -4x+20

y = -4x+20+1

y = -4x + 21

                                                    2)

Given the equation

[tex]y = -4x + 8[/tex]

Comparing with the slope-intercept form of the line equation

[tex]y=mx+b[/tex]    

Where m is the slope and b is the y-intercept

So, the slope of the line = m = -4

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be: 1/4

Thus, an equation of the line that is perpendicular to y = -4x + 8 and passes through the point (5,1), using point slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]  

Here, m is the slope and (x₁, y₁) is the point

substituting the values m = 1/4 and the point (5, 1)

[tex]y-1\:=\:\frac{1}{4}\:\left(x\:-\:5\right)[/tex]

Add 1 to both sides

[tex]y-1+1=\frac{1}{4}\left(x-5\right)+1[/tex]

[tex]y=\frac{1}{4}x-\frac{1}{4}[/tex]
