Answer:
When Mary raises the probability that she has a better hand is 0.273
Step-by-step explanation:
In the poker game it is given that the probability that Mary has a better hand than John is 0.04.
Let the event that Mary has a better hand than John be A.
Let the event that that Mary raises the stakes be B.
It is also given that if Mary has a better hand than John then she would raise with a probability of 0.9
Therefore p(B | A) = 0.9
If Mary has a poorer hand she will raise with a probability of 0.1
Therefore p(B | A') = 0.1
Given that Mary raises the probability that she has a better hand is given by
p(A | B)
= 
= 0.273
So when Mary raises the probability that she has a better hand is 0.273
Answer:
∠EGB= 68°
Step-by-step explanation:
∠EGB= ∠AGF ( vert. opp. ∠s)
∠EGB= 68°
If 2 straight lines intersect, then the angles facing opposite each other are equal. In this case, the 2 lines are AB and EF.
Answer:
D (last one)
Step-by-step explanation:
(x - 3)(x + 11)
Expand
x² + 11x - 3x - 33
Simplify
x² + 8x - 33
To get your answer we'll plug 0 in for x into the equation.
So, multiply 4*0 which equals 0.
Then we'll add 0 and 7 which leaves us with
The y-intercept of this equation is: 
To find the x-intercept of this equation we'll rewrite it as
Then we'll subtract 7 from both sides,
Now we'll divide each side by 4. Then simplify which brings us to our answer,
The x-intercept of this equation is:
