It would be 22/125.
You'd convert the fraction by placing the decimal number over a power of 10.
No, the reverse is not always true, because it isn't always snowing outside when it's cold. However, if it's snowing outside, it must be cold as snow is, essentially, tiny bits of ice.
(gof)(x) = g(f(x))
so
g(f(x)) = 3(6x - 4)^2 -2(6x - 4) - 10
g(f(x)) = 3(36x^2 - 48x + 16) - 12x + 8 - 10
g(f(x)) = 72x^2 - 144x + 48 - 12x - 2
g(f(x)) = 72x^2 - 156x + 46
answer
(gof)(x) = 72x^2 - 156x + 46
The mode is the score that occurs the most often and the median is the middle number when arranged in order.
