800÷20= 40 so 40 winners per draw.
19/20 as a percent is 95%
So 1. 40
2. 95%
Hope this helps!
Sinα=h/L
α=arcsin(h/L)° we are told that h=18 and L=20 so
α=arcsin(9/10)°
α≈64° (to nearest whole degree)
Heres the answer to number 1 but I can't figure out the rest: A = P(1 + i)^n
A = 2400 , P = 1750 , i = 2.3% , n = ?
2400 = 1750(1 + 2.3)^n
2400 = 1750(3.3^n)
1750(3.3^n) = 2400
1750(3.3^n) / 1750 = 2400 / 1750
3.3^n = 48/35
log(3.3^n) = log(48/35)
n(log(3.3)) = log(48/35)
n = log(48/35) / log(3.3)
<span>n = 0.3</span>
