Yes! 40:70 can be simplified! A ratio can be simplified if both numbers have a GCF that is not 1. Looking at 40 and 70, we see that they have a GCF of 10. That means that to simplify 40:70, we need to divide both numbers by 10. 40/10 = 4, and 70/10 = 7, so that means that our simplified ratio is 4:7.
Answer:
slope -1/2, y-intercept: 1
Step-by-step explanation:
1. y-intercept is the point where the line crosses the y axis. Line crosses y axis at (0,1).
2. Equation of a slope for a line given two points on the line is (y2-y1)/(x2-x1). We'll use (0,1) and (2,0).
3. Set one point as (x1, y1) and the other as (x2, y2). The way you assign them doesn't matter, as long as the 0 and 1 and the 2 and 0 remain together. We'll make (0,1) = (x1, y1) and (2,0) = (x2, y2).
4. Plug in the points for the variables in the equation they correspond to.
5. Solve: (0-1)/(2-0)
=-1/2
2/21 is the answer

Answer:
973.68 times
Step-by-step explanation:
Since you would expect to win 1 in 38, the amount of times you will win in 1000 times is 1000 / 38 which is 26.32. therefore you would expect to lose 1000 - 26.32 times which is 973.68
