A cohort study was conducted to examine the relationship between smoking and risk of lung cancer. Among 4000 smokers, 800 were eventually diagnosed with lung cancer and among 6000 non-smokers, 500 were eventually diagnosed with lung cancer. (Use this information to answer questions below)What was the relative risk of being diagnosed with lung cancer in this study?a. 0.08b. 0.13c. 0.20d. 0.40e. 2.40

Step-by-step explanation:

they go with it happens or they mite give a chance?

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
