Answer:
a=1/10, b=17/6
Step-by-step explanation:
IF you mean the points (9,a), (b,3) lie on the line y=2/(3x-7),
then a=2/(3*9-7)=1/10;
3=2/(3b-7)
b=17/6
Answer:
21/20
Step-by-step explanation:
you find a common multiple for the 4 and 5, and multiply to get it. In this case, it would be 20. So, you multiply 1 and 4 by 5 so it would be 5/20. And multiply 4 and 5 by 4 to get 16/20. 5/20+16/20 is 21/20.
Answer: 8/9
Step-by-step explanation:
Taking the probability as
AA = 4/9 AB = 2/9 BA = 2/9 BB = 1/9
These spaces AA,AB,BA,BB is indicates who wins each game.
There is a 2/3 probability that A will win any particular game.
But considering that these events are independent events, the probability that A wins both games is 2/3 and 2/3 which equals to 4/9.
Therefore the probability that A wins at least one match would be 1 − P(BB).
And this gives 1 - (1/9) =
8/9
