The volume of a rock is measured by placing the rock in a graduated cylinder partially filled with water and measuring the increase in volume. Eight independent measurements are made. The average of the measurements is 87.0 mL, and the standard deviation is 2.0 mL.
(a) Estimate the volume of the rock, and find the uncertainty in the estimate.
(b) Eight additional measurements are made, for a total of 16. What is the uncertainty, approximately, in the average of the 16 measurements?
(c) Approximately how many measurements would be needed to reduce the uncertainty to 0.4 mL?

answer: r there any options?

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
