Answer:
Therefore the probability that a person with lung cancer is a smoker is
= 0.58
Step-by-step explanation:
Given, 11% of population smokes. Then(100-11)%=89% of population do not smoke. The probability of getting lung cancer if a person smoker is 0.34. The probability that a nonsmoker will get lung cancer is 0.03.
Cancer
Smoker (11%× 0.34)=3.74%
nonsmoker (89%×0.03)=2.67%
______
6.41%
Therefore the probability that a person with lung cancer is a smoker is
= 0.58
<h3>
Answer: 12,201.90 dollars</h3>
You may need to delete the comma if you are entering this result into a computer system.
=====================================================
Work Shown:
P = 10,000 = deposit
r = 0.04 = decimal form of 4% interest rate
n = 4 = we're compounding 4 times a year
t = 5 years
-------------
A = P*(1+r/n)^(n*t) .... compound interest formula
A = 10,000*(1+0.04/4)^(4*5)
A = 12,201.9003994797
A = 12,201.90
After 5 years, there is $12,201.90 in the account.
This is assuming you do not deposit any more money, and it also assumes that you don't take any money out during the 5 year timespan either.
Answer:
c=16
Step-by-step explanation:
hello :
x2+8x+c is the perfect square means : x²+8x+c= (x+a)²
x²+8x+c = x²+2ax+a²
so : 2a=8
c=a²
a=8/2 = 4 but : c = a²
conclusion : c=16
