A.) P(defective | foo) = P(defective & foo)/P(foo)
4% = P(defective & foo)/30% . . . . . . . . . plug in the given data
0.04*0.30 = P(defective & foo) = 0.012 = 1.2%
The probability that a widget was produced at the foo factory and is defective is 1.2%.
b.) P(defective | foo) ≠ P(defective) (4% ≠ 5%), so the events P(defective) and P(foo) are NOT independent.
c.) P(foo | defective) = P(defective & foo)/P(defective)
P(foo | defective) = 1.2%/5% = 24%
The probability that a widget was produced at the foo factory given it is defective is 24%.

C will be the y-intercept in the equation which will shift it up and down
Answer : A
We want to solve this:
54x + 64 ≥ 49x + 59
First, subtract 49x from both sides and you would get:
5x + 64 ≥ 59
Then subtract 64 from both sides:
5x ≥ -5
Divide both sides by 5:
x ≥ -1
Answer:
x=-6
Step-by-step explanation:
2x-1=3x-7
2x-3x=-7+1
x=-6
