This table shows the number of hours Harry spent watching television and the hours he spent doing his homework on three days last week.
hours of tv: 1.5 2 3
hours of homework: 2 1.5 1
What kind of relationship do these data appear to have?
A. Directly proportional.
B. Inversely proportional.
C. Neither directly nor inversely proportional.
D.Both directly and inversely proportional.
Pls help
This is hard and I don't get it at all.
2/1.5 = 4/3 = 16/12
1.5/2 = 3/4 =9/12
1/3 = 4/12
No constant ratio in this whole scheme so no proportionality
Thanks Damon.
To determine the relationship between the number of hours Harry spent watching television and the hours he spent doing his homework, we need to examine the data.
Looking at the numbers:
- On the first day, Harry watched 1.5 hours of television and did 2 hours of homework.
- On the second day, Harry watched 2 hours of television and did 1.5 hours of homework.
- On the third day, Harry watched 3 hours of television and did 1 hour of homework.
A direct relationship means that as one variable increases, the other variable also increases. An inverse relationship means that as one variable increases, the other variable decreases.
In this case, there is no clear pattern of direct or inverse relationship between the hours Harry spent watching television and the hours he spent doing his homework. On some days, he watched more television and did less homework, while on other days, he watched less television and did more homework.
Therefore, the correct answer is C. Neither directly nor inversely proportional.
