Answer:
C
Step-by-step explanation:
g is distributed
Answer:
its b
Step-by-step explanation:
Use binomial distribution, with p=0.20, n=20, x=3
P(X=x)=C(n,x)p^x (1-p)^(n-x)
P(X>=3)
=1-(P(X=0)+P(X=1)+P(X=2))
=1-(C(20,0)0.2^0 (0.8)^(20-0)+C(20,1)0.2^1 (0.8)^(20-1)+C(20,2)0.2^2 (0.8)^(20-2))
=1-(0.0115292+0.057646+0.136909)
=1-0.206085
=0.793915
I just found 10% of it, which is 14, then found 5% of it through the previous work, which is 7
then i multiplied 7 by 11, because 55/5 is 11, so 55% of 140 is 77
Answer:
75
Step-by-step explanation:
alternate interior angles are always equal, so that means 6 = 4 = 75.
