$2.50
Step-by-step explanation:
60% of 20 is (0.6 x 20) = 12 passes
There are a further 30 quizzes remaining (50 total during the year minus 20 already written)
80% of 30 is (0.8 x 30) = 24 passes
The student has passed (12 + 24) = 36 quizzes out of 50 total, giving an overall pass percentage of ((36 / 50) x 100)) = 72%.
Standardized z score for the act result = (30 - 21.5) / 5.4 = 1.574
so for the sat ressult we have 1.574 = (X - 1498) / 316
X = 316 * 1.574 + 1498 = 1995 answer
