A statistician estimates that the probability the #8 car will win the race tomorrow is 32%. The weather forecast for Reykjavik, Iceland says there is a 16% chance of snow. Assuming snow and the #8 car winning are independent events, what is the probability that it snows and the #8 car wins tomorrow? Give your answer as an exact fraction and reduce the fraction as much as possible.

Simplify (a/b - b/a) times (a - a^2/a+b) a - a^2/a=b is a mixed number

Which expression is not a polynomial?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
