The best way I can explain the elimination method is, it's a method where you either add or subtract equations in order to get rid of a variable.

For elimination you would be canceling out your x or your y. When canceling out one of them you would then be solving for whatever variable is left over. Say you have your y left over and you solved it already, you will take whatever you got for your y and plug it into whichever equation is easiest to solve for x. Once you have both of your variables, y and x, that would be your coordinate.
HOPE THIS HELPS! ^_^

A new surgery is successful 75% of the time. if the results of 10 such surgeries are randomly sampled, what is the probability t
valentinak56 [21]
\text{Binomial Distribution: } P(X = r) = \binom{n}{r}(p)^{r}(1 - p)^{n - r}
P(X < 9) = 1 - P(X = 9) - P(x = 10)

P(X = 9) = \binom{10}{9}(0.75)^{9}(0.25)
P(X = 10) = \binom{10}{10}(0.75)^{10}

P(X < 9) = 1 - \binom{10}{9}(0.75)^{9}(0.25) - \binom{10}{10}(0.75)^{10}
\approx 0.755974769...

2cm = 25mi

1cm = 12.5 (25/2)

5cm is 2 + 2 + 1

2 + 2 + 1 = 25 + 25 + 12.5 = 62.5
