well, from 340 down to 150, their difference is 190.

now, if we take 340 to be the 100%, what is 190 off of it in percentage?

\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 340&100\\ 190&p \end{array}\implies \cfrac{340}{190}=\cfrac{100}{p}\implies p=\cfrac{190\cdot 100}{340}\implies p\approx 55.88

One in 1200 are not particularly good odds. On the other hand, winning the lotto is 1 chance in 13,000,000 which if you've ever played the lotto you know that those odds are good enough to insure that if you played for the rest of your life and you are 18 not expect to live to 80 and you have 104 [given 2 draw a week] chances of winning per year, it likely won't happen. One in 1200 is better but still not good, especially with only 1 draw.

As a fraction her probability of winning is 1/2000 which is 0.000833333 as a decimal. You can put that in as

What are the types of roots of the equation below?<br><br>x^4 - 81 = 0​
natali 33 [55]

Answer:

x^4 - 81 = 0  

(x² - 9)(x² + 9) = 0  

Notice that the first of these is itself a difference of two squares:  

(x - 3)(x + 3)(x² + 9) = 0  

So the solutions are x = 3, x = -3, x = 3i, x = -3i
