U^2(2u+3)+7(2u+3)
(u^2+7)(2u+3)
Answer: 0.421
Step-by-step explanation:
Heavy smoker = 20%
Light smoker = 30%
Non smokers = 50%
We can assume that the probability that a non-smoker is going to die in the next 5 years be y.
Since light smokers were twice as likely as nonsmokers to die during the five-year study, the probability will be:
= 2 × y = 2y
Probability for the Heavy smokers will be:= 2 × 2y = 4y
The expected number of people that will die for each in the next 5 years will be:
Non smoker:
= 50% × y
= 0.5 × y
= 0.5y
Light smoker:
= 30% × 2y
= 0.3 × 2y.
= 0.6y
Heavy smoker:
= 20% × 4y.
= 0.2 × 4y
= 0.8y
Total = 0.5y + 0.6y + 0.8y = 1.9y
The probability that the participant was a heavy smoker will be:
= 0.8y/1.9y
= 0.421
Answer:
A) Y=3X -2
Step-by-step explanation:
<em>Factors and multiples are related by multiplication.</em>
<h2>
Explanation:</h2>
When you multiply numbers together to find a number, say, n, then those numbers are called factors of n. For instance:
On the other hand, a multiple, say, n, results when multiplying a number by an integer. For instance:
So 
is multiple of 
<em></em>
<em>As you can see, both factors and multiples implies a multiplication. So factors and multiples are related by multiplication.</em>
