The answer to the question is 0.022222222
Answer:
Step-by-step explanation:
Given that twenty-three percent of automobiles are not covered by insurance (CNN, February 23,2006).
considering the total number of vehicles, probability for a randomly drawn vehicle not covered by insurance = 0.23
Each vehicle can be treated as independent of the other
Hence X no of vehicles not covered by insurance is Binom with n = 35 and p - 0.23
a) the expected number of these automobiles that are not covered by insurance=E(x) =
![np = 35(0.23)\\= 8.05](https://tex.z-dn.net/?f=np%20%3D%2035%280.23%29%5C%5C%3D%208.05)
b) the variance
=![npq = 8.05(0.77) \\=6.1985](https://tex.z-dn.net/?f=npq%20%3D%208.05%280.77%29%20%5C%5C%3D6.1985)
Std dev = square root of variance = 2.4897
Answer:
2
Step-by-step explanation:
A geometric sequence means that each term is the previous term multiplied by a certain common ratio. For instance, here, -30 is 2 times -15, and -60 is 2 times -30. Hope this helps!
