This is pretty much asking "what squared it 0.09". The answer is 0.3, as 0.3 to the power of 2 is 0.09
The ratio from 80 to 5 would be 16. so divide 144 by 16 and you get 9. Answer:9
Answer:
1: D. 1/336
Explanation:
10 x 9 x 8 = 720
There are 720 ways for them to come in first, second and third place.
2. Probability = 1/8 x 1/7 x 1/6 = 1/336
The probability is 1/336 or 0.002976.

so. hmm which is it? the +/- ? well, neverminding for a second, the value of tangent, just looking at the sign, the tangent is positive,
tangent = opposite/adjacent.... so that only happens, when both are the same sign, + or - both
now, we know the sine is -1/5.. if the sine is negative, the cosine also has t to be negative, so we'd use the -2√(6) = a
thus
Required number
= 1500*(1+2%)^4
=1624(cor.to.the nearest integer)
