Add 8x to both sides of the equation this gives:-
2x + 4 = -12
2x = -16
x = -8 answer
Cos35= y/15
y= 15cos35
y= 12.3 cm
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%
