Therefore , the solution of the given problem of scatter plot comes out to be Line 3 to the right of the graph is best fit line.

Line of best fit refers to a line through a scatter plot of data points that best expression the relationship between those points.The graphs that show the association between two variables in a data set are called scatter plots. It displays data points either on a Cartesian system or a two-dimensional plane.

Here,

In the xy plane, a scatter plot is displayed. The x-axis has values from 0 to 9 with 1 increments, while the y-axis has values from 0 to 9 with 1 increments.

On the x-axis, data points range from 0 to 3; on the y-axis, they range from 0 to 8.5. There are three lines marked Line 1, Line 2, and Line 3. Line 1 connects the points in a way that places the majority of the points on the left of the line,

Line 2 connects the points in a way that places the majority of the points on both sides of the line, and Line 3 connects the points in a way that places the majority of the points on the right of the line.

The equation perpendicular to the line is y= −1/2 x. Therefore, option B is the correct answer.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

In the given graph, the coordinates are (2, 3) and (0, -1)

Slope m=(-1-3)/(0-2)

= -4/(-2)

m=2

Substitute m=2 and (x, y)=(2, 3) in y=mx+c, we get

3=2(2)+c

c=-1

Substitute m=2 and c=-1 in y=mx+c, we get

y=2x-1

Find any equation perpendicular to the line.

y= −1/2 x

Therefore, option B is the correct answer.

The given relation {(-1, 1), (1, 1), (-2, 4), (2, 4)} is a function because: A. yes each input has exactly one output.

In Mathematics, a function can be defined as a mathematical expression which is typically used for defining and representing the relationship that exists between two (2) or more variables such as an ordered pair.

This ultimately implies that, a function is typically used in mathematics for uniquely mapping an input variable (domain) to an output variable (range).

In this context, we can reasonably infer and logically deduce that given relation is a function because each input variable (domain) has exactly an output variable (range) as illustrated below;

Answer:

b. Considering your answer to part (a) and the possible outcomes listed above, how much total revenue (i.e., regular and premium) can be expected from ticket sales?

Answer:

[tex]\boxed{x^2 - x - 6}[/tex]

Step-by-step explanation:

If a is the root of a polynomial then x-a is a factor of that polynomial

Since - 2 is a root, x -(-2) = x + 2 is a factor

Since 3 is a root, x - 3 is a factor

Multiplying the factors of a polynomial gives you the polynomial equation

So the polynomial equation is

[tex](x + 2)(x-3)[/tex]

Apply FOIL method:
[tex](x + 2)(x-3) \\\\= x\cdot x+ x\left(-3\right)+2x+2\left(-3\right)\\\\= x^2 -3x + 2x -6\\\\x^2 - x - 6\\\\Answer: \boxed{x^2 - x - 6}[/tex]

Answer: it should be 946, maybe you worded Wong

Step-by-step explanation:

o obtain an estimate for the computation 348 + 598, we can round the two numbers to the nearest ten.

348 rounded to the nearest ten is 350

598 rounded to the nearest ten is 600

So, our estimate for the sum of 348 + 598 is 350 + 600 = 950

Using a calculator, the actual computation is 348 + 598 = 946

Our estimate of 950 is 4 more than the actual answer of 946. This means that our estimate is slightly higher than the actual answer. This is not a big difference and it is reasonable as the numbers are rounded to nearest 10.

Answer:

The bus journey takes 25 minutes (5 minutes per stop x 5 stops). The bus leaves the Railway Station every 10 minutes (the wait time between circuits).

The first departure is at 09:15, so the bus will arrive back at the Railway Station at:

09:15 + 25 minutes = 09:40

Bart will drive the bus for 4 circuits, so the bus will arrive back at the Railway Station for the final time at:

09:40 + (4 x 25 minutes + 4 x 10 minutes) = 09:40 + 130 minutes =

11:50.

So the final arrival time will be D 11:55.

Answer:

Step-by-step explanation:

Each circuit takes 25 minutes (5 destinations times 5 minutes) plus the 10 minute wait at the Railway Station.  So the entire circuit is 35 minutes with the wait.  Bart drives 4 circuits - 4 times 35 minutes is 140 minutes.

140 minutes equals 2 hours and 20 minutes.

Add 2 hrs and 20 minutes to 9:15 and the sum = 11:35

The answer is B -  11:35

A unit vector u in the direction opposite of ⟨−9,−2,−8⟩  is  ⟨-9/√(149) , -2/√(149) , -8/√(149) ⟩

What are vector equations ?

Vector equations allow for the creation of parametric curves. That is, points in space are formed for each value of the parameter by the equation of a vector, where each of its elements has a function with an independent variable that we refer to as a parameter.

Let unit vector u be = k⟨−9,−2,−8⟩.

√(81k^2 + 4k^2 + 64k^2) = 1

SO k = 1/√(149)

So a unit vector u in the direction opposite of v=⟨−9,−2,−8⟩ = (-9/√(149) , -2/√(149) , -8/√(149))

Answer:

A 10

Step-by-step explanation:

a proportional relationship is defined as

y = kx

k is the constant of proportionality, because it is constant for this function for any value of x.

it is usually called the slope of the line or rate of change.

these are special lines : lines that go through the origin (0, 0).

and for these lines people often call k the constant of proportionality.

Answer: The hour hand of a clock makes one complete rotation, 360 degrees, in 12 hours or 720 minutes.

The hour hand of a clock turns 30 degrees in one hour or 0.5 degrees in one minute.

In this case, the hour hand is turned anticlockwise from 2 pm to 9 am, which is 21 hours.

So, it will have turned 21 * 30 = 630 degrees.

It is important to note that this answer only accounts for the rotation of the hour hand and does not take into account the rotation of the minute hand.

Answer:

maximum value = 2

Step-by-step explanation:

the maximum value of the function is the y- coordinate of its vertex

given a quadratic function in standard form

y = ax² + bx + c (a ≠ 0 )

then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

y = - x² + 2x + 1 ← is in standard form

with a = - 1 and b = 2 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{2}{-2}[/tex] = 1

to find the y- coordinate of the vertex, substitute x = 1 into y

y = - 1² + 2(1) + 1 = - 1 + 2 + 1 = 2

then maximum value of the function is 2

Answer:

  DE = 9

Step-by-step explanation:

Given quadrilateral DEFG with DG≅EF, ∠FDG≅∠DFE, and markings EF=(6x+4), DG=(4x+8), and FG=(4x+1), you want the measure of DE.

The given congruences mean that the figure DEFG is a parallelogram. Opposite sides are the same length.

  EF = DG

  6x +4 = 4x +8

  2x = 4 . . . . . . . . subtract (4x+4)

  x = 2 . . . . . . . . divide by 2

Now, we can find FG.

  FG = 4x+1 = 4(2) +1 = 9

Opposite side DE is the same length:

  DE = 9

Answer: We can write an inequality to show how many hours of television Julia can still watch this week by using the following information:

Julia is allowed to watch no more than 6 hours of television a week.

So far this week, she has watched 2.5 hours.

We can use the inequality x + 2.5 <= 6, where x is the number of hours Julia can still watch this week.

This inequality represents the total number of hours watched (x + 2.5) being less than or equal to the maximum number of hours allowed (6).

To solve this inequality, we can subtract 2.5 from both sides:

x <= 6 - 2.5

x <= 3.5

So, Julia can still watch 3.5 hours of television this week.

Step-by-step explanation:

Answer:

The remaining hours of TV Julia can watch this week can be expressed as

[tex]x \leq 3.5hours[/tex]

Step-by-step explanation:

since Julia is allowed not to watch not more than 6 hours of television a week and she has watched 2.5 hours already

the remaining time (X)  would be expressed as

Answer:

Let's call the two numbers x and y. We know that:

y = x + 14 (because one number is 14 more than the other)

x + y + 7 = 83 (because the sum of the two numbers plus 7 is 83)

We can substitute the first equation into the second equation:

x + (x + 14) + 7 = 83

Simplifying this equation:

x + x + 14 + 7 = 83

2x + 21 = 83

2x = 62

x = 31

So one number is 31 and the other number is 45 (since one is 14 more than the other).
