This question is a thought experiment.
It's essentially asking "Is 2πr² the same or not the same as π(2r)²?"
To figure it out, simply simplify π(2r)²
=π(2r)²
=π(2r)(2r)
=4πr²
Quite obviously, 2πr² is not the same as 4πr²
<em>a</em> = 8 - a train arrives at the station once every 8 minutes, so for any given 8 minute interval, a randomly selected train has uniform probability of arriving at the station at some point in this time.
<em>f(x)</em> = 1/8 - the area under the graph of <em>f(x)</em> must be equal to 1. This area corresponds to a rectangle with length <em>a</em> = 8 and height <em>x</em> such that 8<em>x</em> = 1. Solving for <em>x</em> gives 1/8.
<em>P</em> = 5/8 - this is equal to the area under the graph over the interval [0, 5], which is the area of a rectangle with length 5 and height 1/8.
Answer:
The 9th term would be 10.
Step-by-step explanation:
Each of the odd terms is 2 more than the previous. We do not even need to look at the even terms to find the 9th one.
2, odd, 4, odd, 6, odd, 8, odd, 10
Answer:
Step-by-step explanation:
a+b=41
consecutive=>b=a+1
2a+1=41
2a=41-1=40
a=20 => b=20+1=21
