Question

(12, 18), (10, 15), (6, 9), (4, 6)

What is the average number of heartbeats per second?

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the average number of heartbeats per second, we need to calculate the total number of heartbeats and divide it by the total time elapsed.

First, we need to find the total number of heartbeats: (18 + 15 + 9 + 6) = 48

Next, we need to find the total time elapsed: (12 - 4) = 8 seconds

Finally, we divide the total number of heartbeats by the total time elapsed: 48 / 8 = 6

Therefore, the average number of heartbeats per second is 6.

[AI-generated answer — Step-by-Step Bot]

To find the average number of heartbeats per second, we need to calculate the total number of heartbeats and divide it by the total time.

Given the data points:

(12, 18), (10, 15), (6, 9), (4, 6)

The first number in each pair represents the time in seconds, and the second number represents the number of heartbeats.

To find the total number of heartbeats, we add up the number of heartbeats from each pair:

18 + 15 + 9 + 6 = 48

To find the total time, we add up the time from each pair:

12 + 10 + 6 + 4 = 32

Now, we divide the total number of heartbeats (48) by the total time (32) to find the average number of heartbeats per second:

48 / 32 = 1.5

Therefore, the average number of heartbeats per second is 1.5.

Answer 3

[AI-generated answer — Explain Bot]

To find the average number of heartbeats per second, we need to calculate the average heartbeats over a given time period.

Given the data points you provided, each data point represents a pair in the form (time in seconds, number of heartbeats). Let's calculate the total number of heartbeats and the total time.

Total number of heartbeats = 18 + 15 + 9 + 6 = 48
Total time = 12 + 10 + 6 + 4 = 32

To calculate the average number of heartbeats per second, divide the total number of heartbeats by the total time:
Average number of heartbeats per second = Total number of heartbeats / Total time

Average number of heartbeats per second = 48 / 32

Simplifying the expression, we get:
Average number of heartbeats per second = 1.5

Therefore, the average number of heartbeats per second is 1.5.
