Answer:
They can seat <u>520</u> students.
Step-by-step explanation:
Given:
The night school auditorium is able to seat 8 elementary school groups of 65 students each.
Now, use the distributive property to determine the number of students they can seat.
Total number of elementary school groups = 8.
Number of students in each group = 65.
So, using the distributive property to get the number of students they can seat:
Therefore, they can seat 520 students.
Answer:
Standard deviation = 11.30 m/h
Mean = 57.74 m/h
Step-by-step explanation:
Assume that the travel speed is normally distributed.
The corresponding z-score to the 5th and 90th percentile of normal distribution are, respectively, -1.645 and 1.282.
For any given speed X, the z-score is:
If z = -1.645 for X = 39.15 and z= 1.282 for X=72.23, the following system can be solved for the mean and standard deviation of vehicle speed:
The standard deviation is 11.30 m/h and the mean is 57.74 m/h.
