Answer:
Relation 3 is a function and Relation 4 is nog
1.) 4.358898944
2.) 7.071067812
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
Given :
- 2 - 1/2y = 0
To find :-
Solution :-
<u>The </u><u>gradient</u><u> form</u><u>/</u><u> </u><u>slope</u><u> intercept</u><u> form</u><u> </u>
<u>On </u><u>converting</u><u> </u><u>,</u>
- 2 - 1/2y = 0
- 1/2y = 2
- y = 2*2
- y = 4
- y = 0x + 4
Steps to solve:
7 = 11t
~Divide 11 to both sides
7/11 = 11t/11
~Simplfy
7/11 = t
The fraction can't be simplified any further.
Best of Luck!
