Point estimate (average) = $750
Standard deviation = $85
P(X>$825) = ?
Z = (X-mean)/Standard deviation = (825-750)/85 ≈ 0.88
From Z-table, P(X=825) = 0.8106
Therefore,
P(X>$825) = 1 - P(X=$825) = 1-0.8106 = 0.1894 = 18.94%
Percentage of teachers earning more than $825 is 18.94%.

Answer:
Amount of water left = 25 / 8 cups
Step-by-step explanation:
Given:
Amount of water teacher Sara have =
cups = 55 / 8 cups
Amount of water teacher used = 4/8 cups
Amount of water used by student =
cups = 26 / 8 cups
Find:
Amount of water left
Computation:
Amount of water left = Amount of water teacher Sara have - [Amount of water teacher used + Amount of water used by student]
Amount of water left = [55/8] - [4/8 + 26/8]
Amount of water left = [55/8] - [30/8]
Amount of water left = [55-30] / 8
Amount of water left = 25 / 8 cups
