Answer:
Step-by-step explanation:
We are given that 30% of California residents have adequate earthquake supplies.
a) Ramon variable X denotes the number of the california residents that have adequate earthquake insurance
B) x can take value 1 ,2 ,3 ......
C)The distribution of random variable is geometric distribution with parameter p=0.3
The pmf of geometric distribution is

D)P(X=1) or P(X=2)=P(X=1)+P(X=2)
P(X=1) or P(X=2)=
E)

F)

p is the resident who does not have adequate earthquake supplies.
p = 1-0.3 = 0.7

G)
Answer:
h = 
<u>Step-by-step explanation:</u>
T= 2rπh + 2πr²
Subtract terms that don't include the indicated variable from both sides:
T= 2rπh + 2πr² ⇒ T - 2πr² = 2rπh
Divide values being multiplied by indicated variable from both sides:
T - 2πr² = 2rπh ⇒
= h
