Answer:
Step-by-step explanation:
in this case, x = the number of success in 3 trials, so x is a binomial distributed random variable, hence:
P(x=0) = (3C0)*(0.11)^0*(1-0.11)^(3-0)=0.704969
P(x=1) = (3C1)*(0.11)^1*(1-0.11)^(3-1) = 0.261393
P(x=2) = (3C2)*(0.11)^2*(1-0.11)^(3-2)= 0.032307
P(x=3) = (3C3)*(0.11)^3*(1-0.11)^(3-3)= 0.001331
E(x) = n*p = 3*0.11=0.33
σ = (n*p*(1-p)=0.542
E(y) = n*p = 1700*0.11=187
Answer:
×
Step-by-step explanation:
To find: factors of the composite number
Solution:
Numbers that have exactly two factors are known as prime numbers.
Composite numbers are numbers which have at least 3 factors.
For example,
consider a composite number 54
×
Here, 54 is a composite number as it has factors 1, 54, 2, 27, 3, 18, 6, 9.
In the factorisation ×
, 3 and 2 are prime numbers.
Answer:
The sum is 32766.
Step-by-step explanation:
The 7 terms of the series are as follows:
namely: 6, 24, 96, 384, 1536, 6144, 24576
and their sum is 32766.
