Answer:
Step-by-step explanation:
We are given that
Mean,
%=68.5/100
Standard deviation, 
%=8.2/100
We have to find the probability that a student who wrote the examination had a mark between 80% and 100%.
We know that
Using the formula
Its a solid line going down with a x-intercept of (1, 0) and y-intercept of (1, 0)
We shall use a negative sign for an elevation below sea level, and a positive sign for an elevation above sea level.
Given:
Elevation of city A = -96 ft (below sea level)
Elevation of city C = -24 ft (below sea level)
Let x = elevation of city D.
Part A.
Because the elevation of city D is 1/4 of the elevation of city C, therefore
x = (1/4)*(-24)
Part B.
Because 24/4 = 6, therefore
x = -6 ft.
Answer:
The elevation of city D is 6 feet below sea level.
The answer is negative because the elevation is below sea level.

Step-by-step explanation:
45c = 5 · 9c
10d = 5 · 2d
45c + 10d = 5 · 9c + 5 · 2d = 5(9c + 2d)
