A ball club makes $450,000 when it does not rain. It also loses $250,000 when there is a rain out. If the
probability of it raining is.32, find the expectation of profit?

$226,000
$216,000
$236,000
$256,000

The system of equations graphed below has how many solutions?

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.
