Xavier created a scatterplot and a trend line for data that he collected by comparing the number of minutes he spent playing a game and the number of levels he passed.
According to the graph, which combination of minutes played and levels passed seem most likely to be possible?
A) 2 minutes played and 3 levels passed
B) 17 minutes played and 35 levels passed
C) 20 minutes played and 9 levels passed
D) 50 minutes played and 19 levels passed
Answers
Answer:
Option (C)
Step-by-step explanation:
By using regression line calculator,
Equation of the regression line will be,
y = 0.4881x - 0.85714
Here y = Levels passed
x = Number of minutes played
Now we can check every option given.
Option (A)
For x = 2 minutes,
y = 0.4881(2) - 0.85714
= 0.11906
≈ 0.1
False.
Option (B)
For x = 17 minutes,
y = 0.4881(17) - 0.85714
= 8.2971 - 0.85714
= 7.44
≈ 7th level
False.
Option (C)
For x = 20 minutes
y = 0.4881(20) - 0.85714
= 9.762 - 0.85714
= 8.9
≈ 9th level
True.
Option (D)
For x = 50 minutes,
y = 0.4881(50) - 0.85714
= 24.405 - 0.85714
= 23.54786
≈ 24th level
False.
Therefore, Option (C) will be the correct option.

Which represents the equation 6 x + 3 y = 12 when solved for y?
y = negative 2 x + 4
y = 2 x + 4
y = negative 2 x minus 4
y = 2 x minus 4
Answers
Answer:
y=(-x+2)
Step-by-step explanation:
6x+3y=12
6x+3y-6x=12-6x Subtracting 6x from both sides
3y=12-6x Simplifying
3y/3=12/3-6x/3 Divide both sides by 3
y=(-x+2) Simplifying

12y=-2x=3 simplify expressions
10x +4y =3
2x+12y=3 .......multiply both sides of the equation by -5
10x +4y=3
-10x -60= -15 sum both equations to eliminate a variable (10x cancels
and 3+-5 +-12

Find x if 75% of x = 27.
Answers
36
that is the answer
Answer:
36%
Step-by-step explanation:
"Percent'' or ''%'' means ''out of 100'' or '' per 100'',
Therefore x% can be written as x/100.
So we can write and solve for x;
27/75= x/100
100 X 27/75 = 100 X x/100
2700/75 = 100 X x/100
36=x
27/75= 36/100= 36%

6. Given the implicit curve x^2-ln(x/y)=1 , Write the linear approximation () of the tangent line at (1,1) A) L(x)=-x-2 B) L(x)= -x+2 C) L(x)= -x-1 D) L(x)= -x+1
Answers
Answer:
B) L(x) = -x + 2
Step-by-step explanation:
To find the tangent at (1,1), we differentiate x² - ln(x/y) = 1 with resect to x.
So, x² - ln(x/y) = 1
x² - (lnx - lny) = 1
x² - lnx + lny = 1
differentiating both sides with respect to x, we have
d{x² - lnx + lny]/dx = d1/dx
dx²/dx - dlnx/dx + dlny]/dx = d1/dx
2x - 1/x + 1/y(dy/dx) = 0
1/y(dy/dx) = 1/x - 2x
dy/dx = y(1/x - 2x)
dy/dx evaluated at (1,1) is
dy/dx = y(1/x - 2x)
= (1)(1/1 - 2(1))
= 1 - 2
= -1
This is the gradient of the tangent line.
To find the equation of the tangent line, we use (y - y')/(x - x') = m where y' = 1, x' = 1 and m = gradient of line = dy/dx = - 1
(y - y')/(x - x') = m
(y - y')/(x - x') = dy/dx
(y - 1)/(x - 1) = -1
cross-multiplying,
y - 1 = -1(x - 1)
expanding the bracket, we have
y - 1 = -x + 1
adding + 1 to both sides, we have
y -1 + 1 = -x + 1 + 1
y = -x + 2
So, L(x) = -x + 2
which shape has at least one 1 right angle
Answers
What do squares, rectangles, and right triangles have in common? They all contain at least one right angle!
What shape has at least one right angle?
rectangle
A rectangle is a four-sided shape where every angle is a right angle (90°). Also, the opposite sides are parallel and of equal length.
The shapes which contain at least one right angle from the given shapes are the first and third figures.
Given are four shapes.
It is required to find the shape with at least one right angle.
Now, right angles can be defined as the angle whose measure is exactly 90 degrees.
Anything measure of angle which is less than or greater than 90 degrees is not a right angle.
Consider the first figure.
There are 2 right angles marked in squared shape inside the shape in the right part.
So, the first figure contains the right angle.
In the second figure, all angle measures are 108 degrees. So none is a right angle.
In the third figure, all the angles are right angles since all are marked as squares.
In the last figure, the angle measures are only 73° and 107°. So, this is not right angles.
Hence, the options are first and third figures.
