Hey! Good Morning! (if its morning for you) Easy way to figure these things out is to just graph them an take a look. Since we know this is a parallelogram, we can use the basic rules of them to know for sure where that one last point is. (Or we can use the first way, your choice) So just by graphing those points and looking at the incomplete stricter it created,
We can know the last point lies at (0, 2) (I put this spaced so you don't have to read my entire message lol) Hope this helps and good luck!
(42 - 14sqrt2)/5 because rationalizing means getting the root out of the denominator, which is done by multiplying the denominator by a negative or positive root depending on the situation
1) 1/2 * 1/2 = 1/4
2) 43/100 of mine were heads, and (.43)^2 = .1849
3) 1/2 * 1/2 = 1/4
4)57/100 of mine were tails, and (.57)^2 = .3249
5) 1/2 * 1/2 * 2 (multiply by 2 because order doesn't matter) = 1/2
6) .43 *.57 = .2451
7) There is probably a difference becasue there wasn't enough data. The more times you flip the coin, the closer you'd get to 1/2 head 1/2 tails (theoretically), but you can't flip a coin an infinite amount of times, so it (usually) will not give you an exact 1:1 ratio between heads and tails
(18 - x)^2
If (a - b)^2 then the answer is a^2 - 2ab + b^2
18^2 - 36x + x^2
The answer is x^2 - 36x + 324
Answer:
Statistics makes possible the translation of data into information about causes and effects, health risks and cures. powerful and valuable indicator. The data collected through Vital Statistics system and other methods must be converted into rates if they are to be useful for many public health purposes.
