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) =
b) the variance
=
Std dev = square root of variance = 2.4897
Answer:
$54
Step-by-step explanation:
she had 6 grandchildren and she used $9 for one grandchild so we multiply
9 x 6 = $ 54
Answer:
x=8
Step-by-step explanation:
Answer:
x = -2
∠A = 35
Step-by-step explanation:
x + 37 + x + 57 = 90
reduce:
2x = -4
x = -2
∠A = 37-2 = 35
Answer:
$53.83
Step-by-step explanation:
The question is <em>"What is the expected value for the insurance company?"</em>
<em />
The expected value is the sum of the product of each possibility and its probability.
Thus, we have:
The probability of living is 0.9989 and its value is 153
THe probability of dying is (1-0.9989=0.0011) and its value is -90,000
Now, the expected value is:
E(x) = (0.9989)(153) + (0.0011)(-90,000) = $53.83
