Answer:
Expected Value = -$42 (loss of 42 dollars)
Step-by-step explanation:
Complete Question Below:
<em>"There is a 0.9986 probability that a randomly selected 33-year-old male lives through the year. A life insurance company charges $182 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $110 comma 000 as a death benefit. If a 33-year-old male purchases the policy, what is his expected value?"</em>
<em />
We can say P(survival) = 0.9986 and thus P(not survival) = 1 - P(survival) = 1-0.9986 = 0.0014
Also,
In case 33 year old doesn't live, the payment would be 100,000 - 182 = $99,818
And
In case 33 year old lives, the payment is
-$182
We know, the <em>expected value is the sum of the product of each possibility with its probability.</em>
This means a loss of $42 (or -$42)
Answer:
i) 45km/hr
ii)29 min
Step-by-step explanation:
average speed = distanced travelled / time elapsed
It took 36min and need to convert to hr
36min x 
= 
= 
hours
distanced travelled is 27 km;
average speed = 27km / (9/15hr) = 45 km/hr
Add 36min to 0837 becomes 0913, the train will arrive at 0942 and the wait will be the difference of 0942 - 0913 = 29 min

Answer:
310 in²
Step-by-step explanation:
The general formula for the surface area of a prism is:
SA = 2ab + 2ac + 2bc, where 'a', 'b' and 'c' are the measures of the sides. In this case the lengths are 4 in, 5 in and 15 in.
a = 4 in
b = 5 in
c = 15 in
SA = 2(4*5) + 2(4*15) + 2(5*15)
SA = 40 + 120 + 150 = 310 in²
Answer:
D
Step-by-step explanation:
i multiplied the first equation by 60 to eliminate the fractions: 30x - 45y = 11
i multiplied the second equation by 30 to eliminate the fractions: 12x + 5y = 9
I graphed them and (2/3, 1/5) is the intersection of both lines
