(a) How would you characterize the relationship between the hours spent on homework and the test scores? Explain
For this case what we see is that we have a scatter diagram, which we can model using a linear trend defining the following variables:
x: number of hours studied.
y: test scores.
The linear relationship would be of the form:
y = mx + b
(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework?
y = 8x + 40
For three hours of study we have that the note would be approximately:
y = 8 * (3) + 40
y = 64
(c) What does the number 40 in Part (b) mean in the context of the situation?
The number 40 means that if you do not devote any study time, then you expect the test score to be 40.
Answer:
1) vertical
2) adjacent
Step-by-step explanation:
so, vertical is when two different numbers are congruent and adjacent is numbers next to each other but are no congruent
Assuming that x2=x^2 or x squared
so evaluate
basically subsitute values for x
0
6(0)-0^2
0-0
0
1
6(1)-1^2
6-1
5
2
6(2)-2^2
12-4
8
3
6(3)-3^2
18-9
9
4
6(4)-4^2
24-16
8
5
6(5)-5^2
30-25
5
6
6(6)-6^2
36-36
0
if we were to display the results on a table with the numbers we subsituted on the left and results on the right we would get
0,0
<span>1,5
</span>2,8
<span>3,9
</span><span>4,8
</span><span>5,5
</span>6,0
we notice that the outputs/results go up then down
the outputs were
0,5,8,9,8,5,0 when the inputs were
0,1,2,3,4,5,6
