Answer:
D
Step-by-step explanation:
When solving matrices, we need to get the inverse of the matrix
2 6
0 1 we need to get the inverse
The inverse is
.5 -3
0 1
This is what we have to multiply before the coefficient matrix of 2
-3
Answer:
D) No association
Step-by-step explanation:
In the given scatter plot, the points are scattered everywhere. There is no correlation between the variable x and the variable y.
This is called " no correlation". This means there is no association with the variable x and y.
Therefore, answer is D) No association
Hope this will helpful.
Thank you.
I think it's B i jope that helps but here is some extra info if you like reading(lol)
Earlier in this chapter we have expressed linear equations using the standard form Ax + By = C. Now we're going to show another way of expressing linear equations by using the slope-intercept form y = mx + b.
In the slope-intercept form you use the slope of the line and the y-intercept to express the linear function.
<span><span>y=mx+b</span><span>y=mx+b</span></span>
Where m is the slope and b is the y-intercept.
Example
Graph the equation
<span><span>y−2x=1</span><span>y−2x=1</span></span>
rewrite in slope-intercept form
<span><span>y=2x+1</span><span>y=2x+1</span></span>
Identify the slope and the y-intercept
m = 2 and b = 1
Plot the point corresponding to the y-intercept, (0,1)
The m-value, the slope, tells us that for each step to the right on the x-axis we move 2 steps upwards on the y-axis (since m = 2)
Answer:
