An easy one.
Answer:
Step-by-step explanation:
If you let b = x^2 the problem becomes a whole lot easier. Note that x = √b
x^2 + x - 12
Now factor this trinomial.
(x + 4)(x - 3)
Now put b back into the equation
(√b + 4)(√b - 3)
Answer:
Choice D
Step-by-step explanation:
probability of B given A
given you win the first race, you win the second race
Answer: The correct option is
(D) The probability that you win the second race given that you win the first race.
Step-by-step explanation: We are given the following two events :
A : You win the first race
B : You win the second race.
We are given to select the statement that represents P(B\A).
We know that
for any two events R and Q, the probability P(Q\R) represents the probability of happening of event Q given that the event R has already happened.
Therefore, for the given two events A and B,
the probability P(B\A) represents the probability that you win the second race given that you win the first race.
Thus, (D) is the correct option.
B) 1.6^4
C) 1.6 x 4
D) 1.6 + 4
