What is the sample relative risk?
Sample relative risk = fraction of coal miner who got lung cancer / fraction of non coal miners who got lung cancer
Sample relative risk = (30 / 150) ÷ (5/250)
(1/5) ÷ (1/50
1/5 x 50 = 10

The total of the road is 4800 m long. 4800-1440=3360m
We subtract what they have yet to cover from the total to get what they have covered.
So in 30 days they covered 3360 metres.
3660/30 (3660 is divided into 30 equal groups) = 122m
On average they covered 122 metres per day.
The line (x = 3) will be parallel to y axis, and intersects x - axis at point (3 , 0)
The coordinates of line's x - intercept is (3 , 0)
graph in attachment ~
2(x + y) + 3(x + y)
first distribute:
(multiply 2 into everything in the first parenthesis, and 3 into everything in the second)
2x + 2y + 3x + 3y
Second simplify (add all like terms (adding in this case) )
(2x + 3x) + (2y +3y)
5x + 5y
your answer is: 5x + 5y
hope this helps
