One important thing to note when dealing with probability problems is to look for the words 'or' or 'and'. If you encountered 'or', you'll have to add the probabilities. If you encounter 'and', you'll have to multiply them.

In this problem, you'll have to add the probability for the males and the probability for the smokers. Thus,

Probabilty = 22 + 57 = 79%

3x-2y=6<br><br> y=3/2x-3<br><br> Find the slope, x-intercept, and y-intercept for both equations.
lys-0071 [83]

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have 3x - 2y = 6       <em>subtract 3x from both sides</em>

-2y = -3x + 6      <em>divide both sides by -2</em>

y = 3/2 x - 3

slope: m = 3/2

y-intercept: b = -3

x-intercept for y = 0. Substitute:

3/2 x - 3 = 0      <em>add 3 to both sides</em>

3/2 x = 3       <em>multiply both sides by 2/3</em>

x = 2

<h3>Answer:</h3><h3>slope = 3/2</h3><h3>y-intercept = -3</h3><h3>x-intercept = 2</h3>

----------------------------------------------------------------

y = 3/2 x - 3 it's the same function like first function.
