Use volume displacement to determine the volume of this metal sample to the nearest 0.1 ml.

1 answer:

6 0

The volume displacement method is a manifestation of Archimedes' Principle. This principle states that the volume of the object placed on a known volume of water, is equal to the volume of water displaced. Actually, it could just be any liquid. Thus, whatever the displaced volume is, that is equivalent to the volume of the metal sample. I can't give an exact answer because there is no given information. But the concept works that way.

Answer: d) 0.31

Step-by-step explanation:

Given : In a health club, research shows that on average, patrons spend an average of 42.5 minutes on the treadmill, with a standard deviation of 5.4 minutes.

i.e. $\mu=42.5$ and $\sigma= 5.4$

It is assumed that this is a normally distributed variable.

Let x denotes the time spend by a person on treadmill.

Then, the probability that randomly selected individual would spent between 30 and 40 minutes on the treadmill.

$P(30$

Hence, the required probability = 0.31

Thus , the correct answer = d) 0.31
