Answer:
9+t= 54
Step-by-step explanation:
Answer:The correct option is a)
The upper limit of successes that would be deemed to be usual is 5, so more than 5 successes would be unusual.
Step-by-step explanation:
The mean of a binomial distribution
μ= np where n=10 and p= 0.2 q= 1-p, q= 1-0.2=0.8
μ= 10×0.2=2
σ=√npq
σ=√10×0.2×0.8=1.26
Is unusual for the number of success to be greater than μ + 2.5σ.
= 2+2.5(1.26)
=5 approximately.
So it is unusual for it to be greater than 0.5. The right option Is a)
Answer:
s = q/5 + 6r/5 - 3/5
Step-by-step explanation:
-5s + q = -6r + 3
-5s = -q - 6r + 3
s = q/5 + 6r/5 - 3/5
Solution:
from; f(2)=3
f(2n) nf(2)
(3)(n)
therefore :
f(32)=f(2.16)
f(32)=16f(2)
f(32)=(16)(3)
f(32)=48 final answer
