Answer:
0.6125
Step-by-step explanation:
We have,
P(ripe avocados) = 0.45 , n = 5
by binomial distribution,
P(x=k) = 
P(2 ≤ x ≤ 3) = P(x=2) + P(x=3)
P(x=2) = 
= 10 x (0.45)² x (0.55)³
= 0.3369
P(x=3) = 
= 10 x (0.45)³ x (0.55)²
= 0.2756
So, P(2 ≤ x ≤ 3 ) = 0.3369 + 0.2756
= 0.6125
Answer:
D) AC = 5 and BC = 53
Step-by-step explanation:
Answer:
a) 4.16 years
b) 27.73 years
c) 238.44 years
d) 3,870.53 years
Step-by-step explanation:
Let X be the random variable that measures the decomposition time.
a)
In this case, since the decomposition time is exponentially distributed with a mean of 1/6, we have
and we must find a t such that P(x>t)=0.5.
b)
c)
d)

14.95 would be the answer
