Answer:
Pete
Step-by-step explanation:
Given that:
Mandy's Estimate :
Number of spins , n = 20
Pete's Estimate:
Number of spins, n = 200
A good probability estimate is one which has narrow margin of error with a high degree of confidence. These two variables are affected by sample size.
A high sample size give a narrower margin of error and increases the confidence level probability
Based on the sample size used by each of Pete and Mandy, we can conclude that, Pete's probability estimate would be better due to its significantly higher sample size.
1,000 cubic feet because the pyramid is 4000 cubic feet on an area base of 40.
Definition of a rational number:
A rational number is a number that can be written as fraction of integers.
19/10 is a fraction.
19 and 10 are integers.
19/10 follows exactly the definition of a rational number, so it is rational.
Answer:
The volume of the ball is 
or 
Step-by-step explanation:
we know that
The volume of the sphere ( a ball) is equal to
we have
-----> the radius is half the diameter
substitute
----> exact value of the volume
assume
substitute
-----> approximate value
