Explanation:
1. Europeans spread christianity to Rome, this was a problem because the Romans believed in many gods.
2. The middle ages began when different culture spread and some people wanted to stay traditional.
Answer:

Explanation:
Given that:
Area = 475 acres
The length of the channel (L) = 6870 feet
The average water shield slope (S) = 100 feet/mile
Since; 1 mile = 5280 feet
Burst duration D = 15 min
∴
100 feet/mile = 100/5280
The average water shield slope (S) = 5/264
Using hydrograph method:
The time of concentration 
where;
L = 6870
S = 5/264

min
Since 60 min = 1 hour
32.34 min will be (32.34*1)/60
= 0.539 hour
Lag time 


The time to peak i.e


Since D = 15 min is not equal to
, then we hydrograph apart from
duration lag time.
Then;

Now, we need to determine the peak discharge
by using the formula:

where
484 = peak factor
Recall that A = 475 acres, to miles, we have:
A = 0.7422 mile²

∴


B) 12.5
Interquartile range, part of the descriptive statistics is where you measure the between the difference of Q1 and Q3. Q2 is then the interquartile range. Further, interquartile range is the midpoint or the mid-spread of the data given.
