Answer:
a) Positive linear
b) 72
c) Marks scored when no time is spend on homework.
Step-by-step explanation:
a) relationship between the hours spent on homework and the test scores
As the time spent on homework increases the test score increases.
Similarly if less time is spent on homework, there would be a decrease in test score.
The two variables are directly related.
Thus, there relationship can be expressed as a positive linear relationship.
b) The model function
where y is the test score and x is the time spent on homework in hours.
Score predicted by model when x = 4
Thus, model predict that the score on test will be 72 when 4 hours are spent on homework.
c) Interpretation of 40
When x = 0
Interpretation:
Thus, when Paul spends no time on homework that is zero hours are spend on homework, then, Paul will score 40 on test.
Well if u simplify it it would be 6x+3y+7 bc u subtract 8x from 14x to get 6x
Step-by-step explanation:
2u + 4u - 3u = 18
6u - 3u = 18
3u = 18
3u/3 = 18/3
u = 6
Nothing here makes sense.
-- The question talks about "Figure ABCS", but the picture is ABCD .
Where is 'S' ?
OK. Let's assume that it's really talking about Figure ABCD. Then
the whole problem is loaded with nonsense and red herrings.
-- When a figure is rotated, translated, or both rotated AND translated,
why should the length of any of its sides change ? You can just as well
forget all about the rotation, and just check out the length of the sides
as they sit in the drawing.
-- The third choice is there just to see who has a clue and who has none.
What in the world is "DD" ? It may apply to an article of women's clothing,
but it certainly has no relevance to this drawing. The distance from 'D' to
'D' is zero.
-- The side BC is 1 unit wide and 3 units high.
Its length is √(1+ 9) = √√10 .
So the first choice is not true.
-- The side CD is 4 unit wide and 1 unit high.
Its length is √(16 + 1) = √17.
<u><em>The second choice is true.</em></u>
But wait ! Don't go away.
-- As we've said, "DD" is a zero distance.
So the third choice is nonsense.
-- Side AB is 4 units wide and 1 unit high.
Its length is √(16 + 1) = √17 .
<em><u>The fourth choice is also true.</u></em>
