Answer:
Step-by-step explanation:
For the disease having force of mortality µ.
we apply exponential distribution law
probability of dying within 20 years
p( x <20) = 
= .1
= .9
For the disease having force of mortality 2µ.
we apply exponential distribution law
probability of dying within 20 years
p( x <20) = 1 - 
= 1 - ( .9)²
= 1 - .81
= .19
or 19%

Answer:
What do you mean by a "Good estimate"? There's no picture or questions.
Step-by-step explanation:
Answer:
3x +4y = 118
5x+6y =180
y= $25
Step-by-step explanation:
Let x = the cost of a flashlight
Let y = the cost of a sleeping bag
3x +4y = 118
5x+6y =180
Multiply the first equation by -5
-5(3x +4y) = -5*118
-15x -20y = -590
Multiply the second equation by 3
3(5x+6y) =3*180
15x + 18y = 540
Add the modified equations together.
We are using elimination to eliminate the variable x
-15x -20y = -590
15x + 18y = 540
----------------------------
-2y = -50
Divide by -2
-2y/-2 = -50/-2
y =25
Each sleeping bag costs $25
Answer: (d). Area = 6.8 × 10^3 m^2 (to 2 significant figure)
Step-by-step explanation:
The area to find rectangular is:
Area = length × breadth
Area = 32.30 × 210
Area = 6783 m^2
Area = 6.8 × 10^3 m^2 (to 2 significant figure)
