Answer:
Step-by-step explanation:
SD of mean = 2.3/
= 0.418
5 hours = 300 minutes
300 minutes/55 students = 5.45 min/student
The problem asks what is the probability he needs more than an average of 5 min/student
P(XBAR < 5.0) = P((XBAR - 4.8) / 0.418) < (5.0 - 4.8) /0.418) = P(Z < 0.478) = 0.8893
P(XBAR > 5.0) = 1 - 0.8893 = 0.1107
Answer:
19x - 17
Step-by-step explanation:
d = 7x - 5 - x - 1 = 6x - 6
7x - 5 + 6x - 6 + 6x - 6 = 19x - 17
