25 × x = 45
or 25÷100 × x= 45
multiplying both sides by 100 and dividing both sides by 25, we have x = 45×100÷25
therefore, x = 180
( if you use a calculator simply enter 45×100÷ 25)
ANSWER

EXPLANATION
We want to find an odds ratio from a given probability, which is

We subtract the numerator 1 from the denominator 4 to obtain

The answer is the number of unfavorable outcomes.
The Odds can then be expressed as

The ratio of favourable outcomes to unfavorable outcomes.
Or
A circle equation is (x – h)^2<span> + (y – k)^</span>2<span> = r^</span><span>2 where (h,k) is the center and r is the radius. Now all we have to do is plug in the variables.
Since (h,k)=(5,4) and r= 6
The answer would be C.
