Mathematics

Bond [772]2 years ago
6 0

Answer:

2 days

Step-by-step explanation:

Understanding :

  • Number of men is inversely proportional to the number of days taken to complete a job
  • 6 men take 5 days to complete 1
  • Now the number of men is 15

Solving :

  • Rate of change of men ∝ 1/Rate of change of days
  • 15/6 ∝ 1/(d/5)
  • 2.5 = 5/d
  • d = 2 days

g100num [7]

Answer:

The hiker's elevation  after 145 minutes will be 1958 meters.

Step-by-step explanation:

The equation of the trend line of the scatter plot showing a hiker's elevation is y = 8.77x + 686 .......... (1), where x is in minutes (say) and y is in meters (say).

Now, we have to predict the hiker's elevation after 145 minutes.

So, from equation (1) we get, y = 8.77 × 145 + 686 = 1957.65 ≈ 1958 meters. (Answer)
