2x+3y=6 fins the slope of the line
klasskru [66]
2x + 3y = 6

Put this into y=mx+b form (which is also called slope-intercept form)

Where m=slope and b=y-intercept

In order to put this into slope-intercept form, we simply need to subtract 2x from both side.s

3y = 6 - 2x

Then, divide both sides by 3 so that we fully isolate y.

3y ÷ 3 = (6 - 2x) ÷ 3

Simplify.

y = 2 - 2/3x

Put this into order by moving "x" onto the correct place.

y = -2/3x + 2

Therefore -2/3 is the slope, as it is in the "m" spot.

Hope I helped! :)

VARVARA [1.3K]
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%.
