Male Female Total
Income over $50,000 485 385 870
Income below $50,000 65 65 130
<span>Total 550 450 1,000
Probability of being male: 550/1000 = 0.55
Probability of earning over $50,000: 870/1000 = 0.87
0.55 x 0.87 = 0.4785
Probability of being male and earning over $50,000: 485/550 = 0.8818

Answer:
its option 4
Step-by-step explanation:
(D): 18-2
Aside from its actual definition—“difference” in math terms talks about and/or means to subtract. The difference is the result/answer to a subtraction problem.
Count down until you reach the line the point is on and count to lines until you reach the point
In this case down 2 and right 4
So your slope is negative
And the line crosses the y-axis at 1 so you intercept is 1
-2/4x+1 would be correct but it is not simplified
-1/2x+1 is the correct answer because the equation is simplified
