Answer:
8b- 13 6/7
Step-by-step explanation:
A product of 8 and b just means 8 x b or 8b.
13 6/7 less than that product means subtraction.
Therefore, it would be 8b - ![13\frac{6}{7}](https://tex.z-dn.net/?f=13%5Cfrac%7B6%7D%7B7%7D)
Two events are described as dependent if the outcomes/ occurrence of the first effects the outcome of the second so that the probability is changed. From the choices given, dependent event will be:
determining first, second and third place runners.
This is because, it will require the assumptions that previous races maybe considered to come up with the probabilities.
For the game to be fair it should have 50 50 winning and losing chances right?
You get paid only if u pick a red one and choosing a red one out of all is having a
520=1
chance right? So do u think it's fair ?
-t(5t - 7) = -5
-1 -1
t(5t - 7) = 5
t(5t) - t(7) = 5
5t² - 7t = 5
5t² - 7t - 5 = 0
t = -(-7) ± √(-7)² - 4(5)(-5)
2(5)
t = 7 ± √49 - 4(-25)
10
t = 7 ± √49 + 100
10
t = 7 ± √149
10
t = 0.7 ± 0.1√149
The answer to number one is C
