To find out how much she earned hourly, all we need to do is divide 312 and 39
312 ÷ 39 = 8
Therefore, she was paid $8 per hour
Hope this helps!
To find the slope ...
1) (5,-1)and(2,4)
4+1 / 2-5
5/-3
So slope for #1 would be -3/5
2x + b = w
2x = w - b
x = (w - b)/2
For Independent Events, P(A) × P(B) = P(A∩B)
so we have, P(A∩B) = 0.4×0.1 = 0.04
P(A') = 1 - 0.4 = 0.6
This information can be represented on a Venn diagram as shown below
P(A'∪B) means the union of everything that is not A with everything that is B
P(A'∪B) = 0.06 + 0.54 + 0.04 = 0.64
