3 . Which graph represents a function?
​

Answer:

c

Step-by-step explanation:

right now 15 is the mode because there are 3 of them

if we made it so that there was another 8 there would also be 3 of them

this would mean that there are two modes

Using sampling concepts, it is found that the correct option regarding the sample is given as follows:

It is biased. The sample of people at the ball park is not representative of star city’s residents.

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, we have that only one group is sampled, that is, the people that went to the ballgame, hence the sample is not representative and the correct option is given by:

It is biased. The sample of people at the ball park is not representative of star city’s residents.

Answer:

x = 20°

Step-by-step explanation:

Consecutive interior angles theorem

The pairs of consecutive interior angles formed when two parallel lines are cut by a transversal are supplementary (sum to 180°).

⇒ 4x + 5x = 180°

⇒ 9x = 180°

⇒ x = 20°

Answer:

4x+5x=180

9x/9=180/9

x=20

The surface area of the regular pyramid is 770 [tex]m^{2}[/tex]

Option B. 770  [tex]m^{2}[/tex] is the answer.

The surface area of a pyramid is a measure of the total area that is occupied by all its faces.

We have to find the surface area of the regular pyramid with a base of 6 sides (hexagonal base).

Surface area of pyramid = area of triangles at the lateral sides + area of base (Hexagon)

Surface area of hexagonal base,

[tex]\frac{1}{2}*(Apothem)*(Perimeter) \\= \frac{1}{2}*(6\sqrt{3} )*(72)\\=216\sqrt{3}[/tex]

Surface area of triangular sides = 6 * 1/2 * b *h

                                                       = 3 * 12 *11

                                                       = 396  [tex]m^{2}[/tex]

Now total surface area = 216√3 + 396

                                        = 374.112 + 396

                                        = 770.112

                                        ≈ 770 [tex]m^{2}[/tex]

The surface area of the regular pyramid is 770 [tex]m^{2}[/tex]

Answer:

89.0857

Step-by-step explanation:

Hope this helps! Have a great day!!

Question:

please tell me what 16/7+86.8 is

Answer:

89.08571429

Simplified version:

89.08

Step-by-step explanation:

So you have the fraction:

16 over 7

And you have your whole number/decimal:

86.8

What you would do is:

So your broken down fraction should have the numbers in this specific order: 2.28571429

Add the two number together: (Add 2.28571429 and 86.8)

You would start at the end of your problem

9 + 0 = 9

2 + 0 = 2

4 + 0 = 4

1 + 0 = 1

7 + 0 = 7

5 + 0 = 5

8 + 0 = 8

2 + 8 = 10

2 + 86 = 88 + 1 (From the 10) = 89

So, to conclude, 16/7 + 86.8 = 89.08571429

Then, simplified it is: 89.08 or 89.0/89

If you need to simplify to only one digit after the decimal, the answer would be 89

If you are wondering why then the reason why you wouldn't add the .0 is because you never add the .0 at the end. If your answer is 89.08 then you cannot take away that 0 because you only take away the 0 if its at the end of your answer.

(Examples.)

Answer:

Distributive property

Step-by-step explanation:

The distributive property states that if you have an equation inside parenthesis with a number outside, you should multiply the number with each of the member inside the parenthesis. So lets say you have 3(1-4), you are not going to add the members together after multiplication, you are gonna apply the mathematical equation that was available in the first place, so u will multiply 3×1 - 3×4, this applies to any situation you have. Let’s say you have 3+(4-2), here you cannot multiply the 3 by any of the parenthesis, since there is an addition sign right before it, we conclude that the number should be right beside the parenthesis bcz parenthesis are like multiplication signs. So you have 3(4-2), first step you do is multiply each of the number inside by the number outside, and you will get the subtraction sign in the middle of them. It will look like this 3×4 -3×2, u multiply them all together, with the multiplication first and subtraction at last.

Answer:

5/3 or 1 2/3 (also, there is no graph so I had to do subsitution)

Step-by-step explanation:

If we substitute, we get 3 = 3x-2. We add 2 to both sides and get 5 = 3x

We divide 3 from both sides and get 5/3 = x or x = 5/3

The amount of money that Jordan will earn at the end of 10 years = $12,587.5

The principal amount invested(P) = $9,500

The annual compounded daily interest rate(R) of the account = 3.25%

The time given (T) = 10 years

Simple interest (SI) = P×T × R/100

SI = 9,500×10×3.25/100

SI= 308750/100

SI= $3087.50

Therefore the total amount that would be in the account after 10 years = $9,500 + $3,087.50

[tex](x + 4)^{2} + (y + 1)^{2} = 29[/tex].

Step-by-step explanation:

The equation of a circle of radius [tex]r[/tex] and center [tex](a,\, b)[/tex] is:

[tex](x - a)^{2} + (y - b)^{2} = r^{2}[/tex].

In this question, it is given that the center is [tex](-4,\, -1)[/tex], such that [tex]a = (-4)[/tex] while [tex]b = (-1)[/tex].

The radius of this circle could be found as the distance between the center of this circle, [tex](-4,\, -1)[/tex], and any point on the circle- such as [tex](1,\, -3)[/tex]. Using the distance formula, the radius of this circle would be:

[tex]\begin{aligned}r &= \sqrt{((-4) - 1)^{2} + ((-1) - (-3))^{2}} \\ &= \sqrt{29}\end{aligned}[/tex].

Therefore, the equation of this circle would be:

[tex](x - (-4))^{2} + (y - (-1))^{2} = (\sqrt{29})^{2}[/tex].

Simplify to obtain:

[tex](x + 4)^{2} + (y + 1)^{2} = 29[/tex].

The correct classification for the angle JML is an acute angle.

An acute angle has a measure, or it's smaller, than a right angle.

An acute angle has a measure less than 90 degrees.

Therefore,

let's find the measure of ∠JML

Hence,

∠JML = ∠JMK + ∠KML

∠KML = 180 - 132 = 48 degrees.

Therefore,

∠JML = 41 + 48 = 89 degrees.

Therefore, the correct classification for the angle JML is an acute angle.

Step-by-step explanation:

the pattern here is to divide the previous number by 3

the first number is 15, divided by 3 to give you the second number:5 ,the second number divided by 3 gives us 5/3

using that principle the first six terms are :

15, 3, 5/3 , 5/9, 5/27, 5/81

(just multiply the denominator by 3)

adding we have

[tex]15 + 5 + \frac{5}{3} + \frac{5}{9} + \frac{5}{27} + \frac{5}{81} = \frac{1820}{81} [/tex]

1820/81 in decimal is 22.4691 to the nearest whole number that is 22.

hope this helps!

Step-by-step explanation:

135+k=180(sum of angles on a straight line)

k=180-135

k=45

so now u can use k to solve for x

k+9x is also on a straight line

so k+9x=180

we know k so substitute the value in the equation

45+9x=180

9x=180-45

9x=135

[tex] \frac{9x}{9} = \frac{135}{9} [/tex]

cancel 9 will divide 135 15 times

therefore x=15 degrees

Valentina got 4 times more hair cut off than her sister

Step-by-step explanation:

1 4 4

- × - = -

5 1 5

Valentina got 4 times more hair taken off than her sister, as the ratio between them is 4:1.

The ratio is the simplest form of a fraction involving two quantities determining each other. It is written as a:b, read as "a is to b", and functions as a/b.

In the question, we are informed that Valentina and her sister went together to get haircuts. Valentina got 4/5 of an inch cut off and her sister got 1/5 of an inch cut off.

We are asked to find a comparison between the two.

To find the comparison, we will find the ratio of the haircut Valentina got to that of what her sister got.

Therefore, ratio = (4/5):(1/5) = (4/5)/(1/5) = 4.

Therefore, Valentina got 4 times more hair taken off than her sister.

Answer:

f(x) = x - 3

Step-by-step explanation:

note that y = f(x) , then

x - y = 3 ( add y to both sides )

x = 3 + y ( subtract 3 from both sides )

x - 3 = y , that is

f(x) = x - 3

f(x) = x - 3  is the equation written in function notation, with x as the independent variable.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

To write the equation x - y = 3 in function notation with x as the independent variable, we need to solve for y in terms of x.

x - y = 3

y = x - 3

Therefore, the function represented by the equation x - y = 3, with x as the independent variable, can be written in function notation as:

f(x) = x - 3

So the answer is O f(x) = x - 3.
