Answer:
Age of q = 42 years
Step-by-step explanation:
Ratio of the ages of three people p, q and r is 6 : 7 : 11
Sum of the ages of p and r = 102 years
Age of p =
= 36 years
Therefore, age of r = 102 - 36
= 66 years
Since, ratio of p and q = 6 : 7
Therefore,
q =
q = 42 years
Answer:
you do what it says so 13=x
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that X is binomial with n = 13 and p = 0.30
Pdf of x is
f(x) =
a) f(0) = P(x=0)
=0.00969
= 0.01
b) f(12) =
4.83(10^-6) ~0.00
c)
Answer:
- 60%
- 29.4
Step-by-step explanation:
42 / 70 = 0.6 * 100% = 60%
