Ans: 720
<span>This is equal to the number of different arrangements of three persons from a group of 10 persons </span>
Required number of ways = 10P3 = 720
OR can be solved in this way
select 3 runners (10C3 ways)
These 3 runners can be arranged in 3! ways
<span>Total = 10C3×3! = 720
</span>
sin(48°) = x / 1200ft. Multiply each side by 1200ft.
1200ft × sin(48°) = x.
x = 891.77 ft.
F(q)=0
so, q^2 - 125 = 0
(q)^2 - (5)^2 = 0
(q+5) (q-5) = 0
q = 5, -5
I believe the answer is 6
Only because I see that I can divide 3 and 2 and I know that the answer is 6
