21 is 42% of 50. To do that, you divide 21 by 50, you get .42. You then multiply .42 by 100 to get your answer.
<span>Yes it is true that a continuous function that is never zero on an interval never changes sign on that interval. This is because of ever important Intermediate Value Theorem.</span>
1 out of 52. So 1/52 equals some decimal. Plug in calc.
5-2=3 so x is equal to 3
-3+10 is equal to 7 so y is equal to 10
With this we can conclude that x=3 and y=10
I hope that helps :)
