Let's solve each question step by step using the information from the pictograph titled *"Blinks in a Minute"*, where each eye symbol (👁️) represents 3 blinks.

---

Step 1: Understand the Pictograph



Each eye icon = 3 blinks

We'll count the number of eye icons for each student and multiply by 3 to get total blinks per person.

---

#### Counting Blinks for Each Student

1. Meghan:
- 5 eye icons → 5 × 3 = 15 blinks

2. Winston:
- 4 eye icons → 4 × 3 = 12 blinks

3. Hunter:
- 10 full eyes + 1 half-eye? Wait — let’s check carefully.
Actually, the pictograph shows:
- 9 full eye symbols, then one eye with only one pupil shown (half)?
But looking closely: It appears that each row is made of complete eye icons, and Hunter has 10 full eye icons?
Let’s count:

Looking at the image:
- Hunter has 10 eye icons → 10 × 3 = 30 blinks

*(Note: The last icon might be slightly different, but it's still counted as one full icon unless otherwise specified.)*

So we’ll assume all are full icons.

Hunter: 10 icons → 10 × 3 = 30 blinks

4. Larissa:
- 6 eye icons → 6 × 3 = 18 blinks

5. Miah:
- 7 eye icons → 7 × 3 = 21 blinks

6. Max:
- 5 eye icons → 5 × 3 = 15 blinks

---

Now, summarize:

| Name | Eye Icons | Total Blinks |
|-----------|-----------|--------------|
| Meghan | 5 | 15 |
| Winston | 4 | 12 |
| Hunter | 10 | 30 |
| Larissa | 6 | 18 |
| Miah | 7 | 21 |
| Max | 5 | 15 |

Now Answer Each Question



---

#### a) What data does the pictograph show?

Answer: The pictograph shows how many times each student blinked in one minute.

---

#### b) What is another way you could display the data?

Answer: Another way to display the data is using a bar graph, table, or line plot.

---

#### c) Why was the scale of one eye equals three blinks used?

Answer: The scale of one eye equaling three blinks was used to make the pictograph easier to read and more compact. Since the number of blinks is relatively large, using a scale reduces the number of symbols needed and prevents overcrowding.

---

#### d) How many times did the students blink in all?

Add up all the blinks:

- Meghan: 15
- Winston: 12
- Hunter: 30
- Larissa: 18
- Miah: 21
- Max: 15

Total = 15 + 12 + 30 + 18 + 21 + 15 = 111 blinks

Answer: 111 blinks

---

#### e) Who blinked the most?

From the table: Hunter with 30 blinks.

Answer: Hunter

---

#### f) Who blinked the least?

Winston had 12 blinks — the lowest.

Answer: Winston

---

#### g) How likely is the probability that Hunter would blink the most after two minutes?

This is a prediction based on current trend.

- Hunter blinked the most in one minute.
- Assuming blinking rate stays consistent, Hunter is likely to blink the most again in two minutes.
- However, this is not guaranteed — people may vary.

But since the question asks how likely, and we have no evidence of change, we can say:

Answer: It is very likely that Hunter would blink the most after two minutes, assuming his blinking rate remains consistent.

---

Final Answers:



a) The pictograph shows how many times each student blinked in one minute.
b) A bar graph or table could be used instead.
c) The scale was used to make the graph easier to read and less cluttered.
d) 111 blinks in total.
e) Hunter blinked the most.
f) Winston blinked the least.
g) Very likely, assuming consistent blinking rate.
