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:
There are equal ratios
Step-by-step explanation:
100/25=4 and 15x4 is 60
100/20=5 and 12x5 is also 60
Answer: 4
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes 8/5 x 15/6
For fraction multiplication, multiply the numerators and then multiply the denominators to get 8x15/5x6 = 120/30
Since 120 divided by 30 equals 4 then, 120/30 = 4
Therefore 8/5, 6/15 = 4
