Show Answer Key & Explanations
Step-by-step solution for: Reading Graphs Worksheets | Worsheets library
Let’s go step by step to answer each question based on the bar graph.
First, let’s understand what the graph shows:
- There are 8 teams: Team A through Team H.
- Each team has a colored bar showing how many points they scored.
- The x-axis (bottom) shows “Points scored” from 0 to 120.
- We need to read each bar’s length to find the score for each team.
From the graph (estimating visually):
- Team A: orange bar → ends at 40 → 40 points
- Team B: yellow bar → ends at 100 → 100 points
- Team C: blue bar → ends at 50 → 50 points
- Team D: green bar → ends at 110 → 110 points
- Team E: red bar → ends at 80 → 80 points
- Team F: purple bar → ends at 50 → 50 points
- Team G: pink bar → ends at 60 → 60 points
- Team H: light blue bar → ends at 100 → 100 points
Now let’s answer each question:
---
1. Which team won the contest?
The team with the highest score wins.
Team D has 110 points — that’s the highest.
→ Team D
---
2. How many points did Team F score?
Team F’s bar ends at 50.
→ 50 points
---
3. How many more points did Team D get than Team G?
Team D: 110
Team G: 60
Difference: 110 - 60 = 50
→ 50 points
---
4. Which teams scored equally?
Look for bars that end at the same point.
Team C: 50
Team F: 50
Also, Team B: 100
Team H: 100
So two pairs: (C and F), (B and H)
But the question says “which teams scored equally” — probably expects all pairs.
Since it’s likely expecting one pair or listing them, we’ll list both pairs.
But if only one answer is allowed, maybe the first pair? Let’s check context — no restriction.
Actually, looking again — Team C and F both have 50; Team B and H both have 100.
So answer should include both. But since it’s a fill-in, perhaps write:
→ Team C and Team F; Team B and Team H
But maybe the worksheet expects just one pair? Let’s see — in most such worksheets, if multiple pairs exist, you list all.
We’ll go with both.
Wait — actually, rechecking:
Team C: 50
Team F: 50 → yes
Team B: 100
Team H: 100 → yes
So two pairs.
But perhaps the question means “which teams” as in name them. So:
→ Team C, Team F, Team B, and Team H — but that’s not precise. Better to say pairs.
Actually, standard way: “Team C and Team F scored equally; Team B and Team H scored equally.”
But since it’s a short answer line, maybe:
→ Team C and F; Team B and H
I think that’s acceptable.
---
5. What is the difference in the amount of points Team E scored and the amount Team H scored?
Team E: 80
Team H: 100
Difference: 100 - 80 = 20
→ 20 points
---
6. How many teams scored fewer than 100 points?
List scores:
A: 40 → <100 → yes
B: 100 → not fewer → no
C: 50 → yes
D: 110 → no
E: 80 → yes
F: 50 → yes
G: 60 → yes
H: 100 → no
So teams: A, C, E, F, G → that’s 5 teams.
→ 5 teams
---
7. What is the average points of the top 3 highest teams?
Top 3 scores:
D: 110
B: 100
H: 100
(Team E is 80, so not top 3)
Average = (110 + 100 + 100) / 3 = 310 / 3 ≈ 103.333...
But since points are whole numbers, maybe round? Or keep as fraction?
In school, often decimal to one place or fraction.
310 ÷ 3 = 103.333... → usually written as 103.3 or 103 1/3.
But let’s see — the graph uses whole numbers, so perhaps expect decimal.
Actually, 310 ÷ 3 = 103.333... → we can write as 103.3 if rounding to one decimal, but better to be exact.
In many worksheets, they accept fraction or decimal.
But let’s calculate exactly: 310 / 3 = 103.333... → so 103.3 if rounded, but perhaps write as mixed number.
However, for simplicity, since it’s an average, and scores are integers, decimal is fine.
But let me double-check top 3:
Scores: 110, 100, 100, 80, 60, 50, 50, 40 → top 3 are 110, 100, 100 → sum 310, average 310/3 = 103.333...
I think for school level, they might expect 103.3 or 103 1/3.
But looking at the graph, all values are integers, so perhaps they want exact value.
Another thought: maybe I misread Team B and H? Both are 100, yes.
Perhaps the answer is 103.3, but let’s see — in the context, maybe write as fraction.
But I think for this level, decimal is acceptable.
Actually, let’s compute: 310 ÷ 3 = 103.333... so approximately 103.3, but to be precise, we can say 103 and 1/3.
But in the answer blank, probably write 103.3 or 103.33.
Wait — let’s see the other answers — they are integers except possibly this one.
Perhaps I made a mistake — is there another team with 100? Only B and H.
Team D is 110, then B and H at 100, so yes.
Average = 310/3 = 103.333...
I think we should write it as 103.3 if rounding to one decimal, but since it's money or points, sometimes they keep fraction.
But in the worksheet, it's "points", so likely decimal is fine.
To be safe, let's write 103.3, but actually, 310/3 is exactly 103.333..., so perhaps write as 103.33 if two decimals.
But I think for this, since it's a bar graph with whole numbers, and average might not be whole, we'll go with 103.3.
Wait — let me check online or standard practice — in many such worksheets, they accept the fraction or decimal.
But to match the format, perhaps write 103.3.
Another idea: maybe the top 3 are D, B, H — scores 110,100,100 — average 310/3 = 103.333... so we can write 103.3 if rounded to nearest tenth.
I think that's fine.
But let's confirm calculation: 110 + 100 = 210, +100 = 310. 310 divided by 3 is 103.333... so yes.
→ 103.3 (rounded to one decimal place)
But perhaps the worksheet expects exact value. Since it's a math problem, maybe write as mixed number.
But in the context of the other answers being integers, this might be the only non-integer.
I recall that in some curricula, they teach to leave as fraction.
But for now, I'll put 103.3, but let's see the final decision.
Actually, upon second thought, since the scores are all integers, and average is not, but in the answer, we can write 103 1/3 or 103.33.
But to be precise, let's calculate: 310 ÷ 3 = 103.333... so if we round to nearest whole number, it's 103, but that's not accurate.
I think for accuracy, we should write 103.3 if one decimal, or 103.33 if two.
But looking at the graph, the axis has marks at 20,40,etc, so precision is to 10 or so, but scores are exact.
Perhaps the expected answer is 103.3.
I'll go with 103.3 for now.
But let's move on and come back.

8. List the 5 teams with the most points.
Sort the teams by score descending:
1. Team D: 110
2. Team B: 100
3. Team H: 100
4. Team E: 80
5. Team G: 60
Then Team C and F: 50, Team A: 40
So top 5: D, B, H, E, G
Note: B and H are tied, but both are included.
→ Team D, Team B, Team H, Team E, Team G
---
Now, let's compile all answers:
1. Team D
2. 50
3. 50
4. Team C and Team F; Team B and Team H (or however to write)
5. 20
6. 5
7. 103.3 (or 103 1/3)
8. Team D, Team B, Team H, Team E, Team G
For question 4, since it's "which teams scored equally", and there are two pairs, we should mention both.
In many worksheets, they might expect "Team C and F" as one pair, but since B and H also, better to include both.
Perhaps write: "Team C and F; Team B and H"
For question 7, let's decide: since 310/3 is 103.333..., and in school math, often they write it as a decimal to one or two places. I think 103.3 is acceptable, but to be more accurate, 103.33.
But let's calculate exactly: 310 ÷ 3 = 103.333... so if we round to nearest tenth, it's 103.3.
I think it's fine.
Now, for the final answer, since the user wants only the final answer after reasoning, and the options are false for explain/teach/practice, we just need to provide the answers to the 8 questions.
But the response format says: "Final Answer: [Provide only the final correct answer]"
But there are 8 questions, so probably list all answers.
Perhaps write them in order.
Also, for question 4, to be clear, let's write: "Team C and F, Team B and H"
For question 7, let's use 103.3
But let me double-check the scores from the graph to ensure accuracy.
Re-examining the graph description:
- Team A: orange, to 40 — yes
- Team B: yellow, to 100 — yes
- Team C: blue, to 50 — yes
- Team D: green, to 110 — yes (since 100 to 120, and it's halfway? 110 is reasonable)
- Team E: red, to 80 — yes
- Team F: purple, to 50 — yes
- Team G: pink, to 60 — yes
- Team H: light blue, to 100 — yes
All seem correct.
For question 6: teams with fewer than 100: A(40), C(50), E(80), F(50), G(60) — that's 5, yes. B and H are 100, not fewer, D is 110.
For question 7: top 3: D(110), B(100), H(100) — sum 310, average 310/3 = 103.333...
In some contexts, they might expect the fraction, but I think for this level, decimal is fine.
Perhaps write as 103 1/3, but in decimal is more common.
I'll go with 103.3
Now, for the final answer, since it's multiple questions, we need to list all answers.
The instruction says: "Final Answer: [Provide only the final correct answer]"
But for multiple parts, probably list them numbered.
So:
Final Answer:
1. Team D
2. 50
3. 50
4. Team C and Team F; Team B and Team H
5. 20
6. 5
7. 103.3
8. Team D, Team B, Team H, Team E, Team G
For question 4, to make it clear, perhaps "Team C and F scored equally; Team B and H scored equally" but that's long. Since it's a fill-in, maybe "C and F, B and H"
I think it's ok.
For question 7, let's confirm if it's exactly 103.3 or if we should use fraction.
Upon second thought, in many educational materials, for average, they might expect the exact value. Since 310/3 is 103 1/3, and 1/3 is repeating, but in writing, we can put 103.33 if two decimals.
But to be safe, let's calculate: 310 ÷ 3 = 103.333... so if we round to one decimal, it's 103.3, to two decimals 103.33.
I think 103.3 is sufficient.
Perhaps the worksheet has integer answers, but this one isn't, so it's fine.
Another idea: maybe I misidentified the top 3. Is there a team with score between 100 and 110? No, D is 110, then B and H at 100, E at 80, so yes.
Team G is 60, etc.
So I think it's correct.
Now, for the response, since ExplainAnswer, TeachTopic, GeneratePractice are all false, we only provide the Final Answer section with the answers to the 8 questions.
So, let's write it clearly.
First, let’s understand what the graph shows:
- There are 8 teams: Team A through Team H.
- Each team has a colored bar showing how many points they scored.
- The x-axis (bottom) shows “Points scored” from 0 to 120.
- We need to read each bar’s length to find the score for each team.
From the graph (estimating visually):
- Team A: orange bar → ends at 40 → 40 points
- Team B: yellow bar → ends at 100 → 100 points
- Team C: blue bar → ends at 50 → 50 points
- Team D: green bar → ends at 110 → 110 points
- Team E: red bar → ends at 80 → 80 points
- Team F: purple bar → ends at 50 → 50 points
- Team G: pink bar → ends at 60 → 60 points
- Team H: light blue bar → ends at 100 → 100 points
Now let’s answer each question:
---
1. Which team won the contest?
The team with the highest score wins.
Team D has 110 points — that’s the highest.
→ Team D
---
2. How many points did Team F score?
Team F’s bar ends at 50.
→ 50 points
---
3. How many more points did Team D get than Team G?
Team D: 110
Team G: 60
Difference: 110 - 60 = 50
→ 50 points
---
4. Which teams scored equally?
Look for bars that end at the same point.
Team C: 50
Team F: 50
Also, Team B: 100
Team H: 100
So two pairs: (C and F), (B and H)
But the question says “which teams scored equally” — probably expects all pairs.
Since it’s likely expecting one pair or listing them, we’ll list both pairs.
But if only one answer is allowed, maybe the first pair? Let’s check context — no restriction.

But since it’s a short answer line, maybe:
→ Team C and F; Team B and H
I think that’s acceptable.
---
5. What is the difference in the amount of points Team E scored and the amount Team H scored?
Team E: 80
Team H: 100
Difference: 100 - 80 = 20
→ 20 points
---
6. How many teams scored fewer than 100 points?
List scores:
A: 40 → <100 → yes
B: 100 → not fewer → no
C: 50 → yes
D: 110 → no
E: 80 → yes
F: 50 → yes
G: 60 → yes
H: 100 → no
So teams: A, C, E, F, G → that’s 5 teams.
→ 5 teams
---
7. What is the average points of the top 3 highest teams?
Top 3 scores:
D: 110
B: 100
H: 100
(Team E is 80, so not top 3)
Average = (110 + 100 + 100) / 3 = 310 / 3 ≈ 103.333...
But since points are whole numbers, maybe round? Or keep as fraction?
In school, often decimal to one place or fraction.
310 ÷ 3 = 103.333... → usually written as 103.3 or 103 1/3.
But let’s see — the graph uses whole numbers, so perhaps expect decimal.

However, for simplicity, since it’s an average, and scores are integers, decimal is fine.
But let me double-check top 3:
Scores: 110, 100, 100, 80, 60, 50, 50, 40 → top 3 are 110, 100, 100 → sum 310, average 310/3 = 103.333...
I think for school level, they might expect 103.3 or 103 1/3.
But looking at the graph, all values are integers, so perhaps they want exact value.

I think that's fine.
But let's confirm calculation: 110 + 100 = 210, +100 = 310. 310 divided by 3 is 103.333... so yes.
→ 103.3 (rounded to one decimal place)
But perhaps the worksheet expects exact value. Since it's a math problem, maybe write as mixed number.
But in the context of the other answers being integers, this might be the only non-integer.

8. List the 5 teams with the most points.
Sort the teams by score descending:
1. Team D: 110
2. Team B: 100
3. Team H: 100
4. Team E: 80
5. Team G: 60
Then Team C and F: 50, Team A: 40
So top 5: D, B, H, E, G
Note: B and H are tied, but both are included.
→ Team D, Team B, Team H, Team E, Team G
---
Now, let's compile all answers:
1. Team D
2. 50
3. 50
4. Team C and Team F; Team B and Team H (or however to write)
5. 20
6. 5

- Team G: pink, to 60 — yes
- Team H: light blue, to 100 — yes
All seem correct.
For question 6: teams with fewer than 100: A(40), C(50), E(80), F(50), G(60) — that's 5, yes. B and H are 100, not fewer, D is 110.
For question 7: top 3: D(110), B(100), H(100) — sum 310, average 310/3 = 103.333...
In some contexts, they might expect the fraction, but I think for this level, decimal is fine.

4. Team C and Team F; Team B and Team H
5. 20
6. 5
7. 103.3

For question 4, to make it clear, perhaps "Team C and F scored equally; Team B and H scored equally" but that's long. Since it's a fill-in, maybe "C and F, B and H"
