Answer:
Step-by-step explanation:
Let's substitute the first equation into the second one.
- Multiply by and bring all the terms to one side.
I'll use my graphical calculator to solve this but you could factor:
(All rounded to 2 decimal places)
Now we can substitute these values into an equation for .
Answer:
0.03177
Step-by-step explanation:
Prob (Bld grp) ~ Bin (N, P)
N = 15, P = Prob of success ie 'O' blood type = 0.45
P (BG = 0) for 3 people = (N c X) P^X . (1-P)^N-X
As X = 3. So Prob = (15 c 3) (0.45)^3 (0.55)^12
= 455 (0.091125) (0.0007662)
= 0.03177
Possible zeros: Factors of P/Factors of Q, where P is the constant and Q is the leading coefficient.
P = 35: 1, 5, 7, 35
Q = 2: 1, 2
+1, -1, +1/2, -1/2, +5, -5, +5/2, -5/2, +7, -7, +7/2, -7/2, +35, -35, + 35/2, -35/2
