Thank you for posting your question here. I think the question is "
<span>What is the estimated mean for the population? Explain your answer and show your work."

Below is the solution. I hope it helps.

</span>µ= (1*248 +2*567 +3*1402 +4*728 +5*419 +6*456 +7*203)/(1 +2 +3 +4 +5 +6 +7) 
<span>=14752/28≈ 526.9</span>

Answer:

  • Tyler
  • 2 hundredths of a mile

Step-by-step explanation:

The graph is a little difficult to read, but we note that there are 6 grid lines between times that are 2 minutes apart. So, each grid line stands for 2/6 = 1/3 minute.

At the 1-mile mark, the graph crosses 1 grid line above 8 minutes, indicating it takes Tyler 8 1/3 minutes to run 1 mile.

Then in 10 minutes, Tyler will run ...

  distance = speed · time = 1 mile/(8 1/3 min) · 10 min

  = 1/(25/3)·10 = 10·3/25 = 30/25 = 1.2 . . . . miles

__

The equation tells you that Elena runs each mile in 8.5 minutes. To see how far she runs in 10 minutes, we can solve ...

  10 = 8.5x

  x = 10/8.5 ≈ 1.18 . . . . miles

So, Tyler runs farther in 10 minutes by a distance of ...

  1.20 -1.18 = 0.02 . . . . miles
