780 feet because 200 feet below sea level means -200 and 580 feet above sea level mean +580 so if you add 580 and the 200 you get the distance between the two points.
Answer:
Basketball 300
Football 100
Baseball 50
Soccer 150
Step-by-step explanation:
Half of the students would choose basketball
so 600/2 = 300
Half of the remaining students would choose soccer
so 300/2 = 150
2/3 of the remaining students would choose football
so 150 x 2/3 = 100
1/3 of the remaining students would choose baseball
150 x 1/3 = 50
Proving a relation for all natural numbers involves proving it for n = 1 and showing that it holds for n + 1 if it is assumed that it is true for any n.
The relation 2+4+6+...+2n = n^2+n has to be proved.
If n = 1, the right hand side is equal to 2*1 = 2 and the left hand side is equal to 1^1 + 1 = 1 + 1 = 2
Assume that the relation holds for any value of n.
2 + 4 + 6 + ... + 2n + 2(n+1) = n^2 + n + 2(n + 1)
= n^2 + n + 2n + 2
= n^2 + 2n + 1 + n + 1
= (n + 1)^2 + (n + 1)
This shows that the given relation is true for n = 1 and if it is assumed to be true for n it is also true for n + 1.
<span>By mathematical induction the relation is true for any value of n.</span>

Hello!
2,230 rounded to the nearest thousand is: 2,000
13,587 rounded to the nearest thousand is: 14,000
Add:
2,000 + 14,000 = 16,000
The sum is approximately 16,000.
