Answer:
P(X=0) = 0.25
P(X=1) = 0.50
P(X=2) = 0.25
Step-by-step explanation:
The possible outcomes of this event are: BB, BG, GB and GG.
There is one out of four events (GG) in which there are two girls (X=2).
There is one out of four events (BB) in which there are no girls(X=0).
There are two out of four events (GB and BG)) in which there is one girl (X=1).
Therefore, the probability distribution of X is:
P(X=0) = 1/4 = 0.25
P(X=1) = 2/4 = 0.50
P(X=2) = 1/4 = 0.25
I think 3 or 2 if this is not right am sorry ;-;
1.6 -1.6 +1.6 is the following
Answer: 21, 28
Step-by-step explanation:
- Side #1 = x
- Side #2 = x + 7
- Hypotenuse = 35
Use the Pythagorean Theorem 
:
Substitute in the values & solve:
<em><u>-28 is not a possible solution since you can't have negative inches...</u></em>
- a = x = 21
- b = x + 7 = 21 + 7 = 28
- c = 35
Answer:
The first one: 19/15a
second one: b²-4ac = D
Step-by-step explanation:
for first one: take LCM and solve
for second one: you square the expression on both sides then b²= D + 4ac, then when you take 4ac to the left hand side, it becomes b²-4ac= D
