Answer:
tank 1 : 19 gallons
tank 2 : 42 gallons
Step-by-step explanation:
tank 1 : x
tank 2 : 2x+4 ( 4 more than <u>twice</u> the other )
x + ( 2x + 4 ) = 61
3x + 4 = 61 [ add x + 2x = 3x ]
3x = 57 [ subtract 4 on both sides ]
x = 19 [divide 3 on both sides ]
tank 1 : 19 gallons
tank 2 : 42 gallons

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
