D is the only x-intercept out of the options listed below.
In order to find an x-intercept, you need a value that will cause the y-value to equal 0, since this is where x-intercepts exist.
Automatically, A and B do not work since the y-values in the ordered pairs do not equal 0. By definition they are not x-intercepts. Next we can try the x-values in the equation to see which gives us a 0 y-value.
C
f(x) = (x + 6)(x - 3)
f(6) = (6 + 6)(6 - 3)
f(6) = (12)(3)
f(6) = 36
Since this does not equal 0, it is not an x-intercept.
D
f(x) = (x + 6)(x - 3)
f(-6) = (-6 + 6)(-6 - 3)
f(-6) = (0)(-9)
f(-6) = 0
This shows us that D yields a 0 value for y and is thus a x-intercept.
A.) (-2,-7) is the answer.
The answer to this question would be: <span>C. 259,459,200
</span>To answer this question, you will need to understand how to use permutation in probability. In this question, there will be 9 people out of 13 people that make an order for batting. In this case, if same people used but the batting order is different that could be considered different ways. Then the answer would be: P(13,9)= 13! / (13-9)!= 13!/4!= <span>259,459,200 </span>
correct Ans:
P(H) = 0.60
P(W | H) = P(H and W)/P(H)=
0.33
0.20/0.60
my mistake:
P(H and W) = 0.20
