The table below shows the height and the hand span of five students.
Which pattern of association best describes the relationship between the height and the hand span?
A. no association
B. nonlinear association
C. positive linear association
D. negative linear association
There is no association between the height and the hand span.
We can only establish an association when there is a consistent rate of increase or decrease between two variables. The increase or decrease is linear when they occur smoothly.
As we can see, we can not establish any particular relationship between the height and the hand span hence we conclude that there is no association between them.

Click to show whether each equation represents a linear or nonlinear function.
Answer:
[tex]y = x^2 + 1[/tex] -- Nonlinear
[tex]y = x^1 + 2[/tex] -- Linear
[tex]y = x[/tex] --- Linear
[tex]y = 5(x + 2)[/tex] --- Linear
[tex]y = x(x)[/tex] --- Nonlinear
Step-by-step explanation:
Required
Categorize each function as linear or nonlinear
First, it should be noted that a linear function has the form [tex]y = mx + b[/tex].
So, the following question will be solved based on the above form
(a):
[tex]y = x^2 + 1[/tex]
This can not be expressed as [tex]y = mx + b[/tex]
Hence, it is a nonlinear function
(b):
[tex]y = x^1 + 2[/tex]
This can be further expressed as:
[tex]y = x + 2[/tex]
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(c):
[tex]y = x[/tex]
This can be further expressed as:
[tex]y = x + 0[/tex]
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(d):
[tex]y = 5(x + 2)[/tex]
This can be further expressed as:
[tex]y = 5x + 10[/tex] -- by opening the bracket
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(e):
[tex]y = x(x)[/tex]
This can be further expressed as:
[tex]y = x^2[/tex] --- by opening the bracket
This can not be expressed as [tex]y = mx + b[/tex]
Hence, it is a nonlinear function
Draw a line representing the "rise" and a line representing the "run" of the line. State
the slope of the line in simplest form.
Answer: The slope of the line is 3/5 or 0.6
Step-by-step explanation: The line you drew was run of 4 and -1 and the rise was 7 and 4.
y=y1-y2/x1-x2
7-4/4-(-1)
7-4/4+1
3/5 or 0.6
BRAINLEIST Using the graph below, find the missing value to complete the t-chart.
x y
-3 5
0 -1
2 ?
A.5
B.-3
C.-5
D.3
Answer: C. (2, -5 )
Step-by-step explanation:
These are the coordinates of the points on the line
We can see (-3, 5) and (0, -1) on the line.
To find the y-coordinate of a point when the x-coordinate is 2, all you have to do is look for the x-intercept of 2 and look for the y-intercept.
When you look at the bottom of the graph, you can see that the x-coordinate 2 and the y-coordinate -5 intersect to form a point.

Please Help and write the equation down as well!!
I´ll mark whoever is right Brainiest!
Answer:
y=6x+4
Step-by-step explanation:
now the formula for slope-intercept is y=mx+b
Slope (aka m) is 6
[how I got the slope is every time it goes forward 1 it goes up 6 rise/run]
so y=6x+[y intercept]
the y intercept is 4 as seen in the chart so:
y=6x+4

Step-by-step explanation:
(this is how I did it, like I said, not sure its right)
Dotted line:
we need to find the length of the dotted line in order to be able to calculate the area of the rectangle
radius = 8 in
diameter (dotted line)
= 8 x 2
= 16 in
(radius is half the diameter so now you know the length of the dotted line is 16 in - this answer is for the rectangle)
Area of the rectangle
A = L x W
using the 16 we found to calculate the area of the rectangle
A = 23 x 16
A = 368 in
Area of semi-circle:
Now to calculate the area of the semi-circle
A = π r² ÷ 2
A = π 8² ÷ 2
= 100.48
Adding the area of the rectangle and semi-circle together:
= 100.48 + 368
= 468.48
1dp = 468.5

Sara can travel 23 feet in 11 hours. Please calculate Sara's rate of speed. (round to 2 decimal places)
A. 2.09 feet per hour
B. 0.21 hours per feet
C. 2.09 hours per feet
D. 0.21 feet per hour
Answer:
I think is C sorry if i'm incorrect
Step-by-step explanation:
Answer:
A. 2.09 feet per hour
Step-by-step explanation:
Speed= Distance/Time
All you have to do is divide the time by distance
like this: 23 ÷ 11
The answer would be 2.090909090909091, but since you are rounding the answer would be A. 2.09
But don't forget that you want to know how far she is going per hour
