4 yellow + 6 green + 10 purple = 20 total tiles

1st draw P purple: 10 purple/20 total
2nd draw P purple: 9 purple/19 total

Probability purple then purple (no returns): \frac{10}{20} x  \frac{9}{19}
= 90/380
= 45/190
= 9/38

one standard deviation lie within 68% of the mean

Two standard deviations lie within 95%

Three standard deviations lie within 99.7%

Hence, for the question given, 95% fall within 2 standard deviations of the mean

How do you convert 14x + 19y = 20 into slope intercept form?
nevsk [136]

Subtract 14x from both sides. Then divide both sides by 19

14x + 19y = 20\\\\19y = 20-14x\\\\19y = -14x+20\\\\y = \frac{-14x+20}{19}\\\\y = \frac{-14x}{19}+\frac{20}{19}\\\\y = -\frac{14}{19}x+\frac{20}{19}\\\\

The equation is now in slope intercept form y = mx+b

m = -14/19 is the slope

b = 20/19 is the y intercept
