Answer:
B
Step-by-step explanation:
That delivery truck driver charges a fixed base price of $6 for 2 miles.
After 2 miles, he charges an additional $2 for every mile and after 6 miles, he charges an additional $4 for every mile.
We need to describe the cost of the delivery truck between 1 mile and 2 miles.
In the given graph x-axis represents the distance in miles and y-axis represents the cost in dollars.
From the given graph it is clear that the value of function is constant between x=1 and x=2.
It means the cost of the delivery truck between 1 mile and 2 miles is constant.
Therefore, the correct option is B.

Answer:
The relation between m and n is , m = n
Step-by-step explanation:
Given as :
The average for n class = 0.82 = 82%
The average for m class = 0.78 = 78%
The average for ( m + n ) class = 80%
So , 
= 82%
And 
= 78%
And , 
= 80%
So , 0.82×n + 0.78×m = 0.80× (m+n)
Or, 0.82×n - 0.80×n = 0.80×m - 0.78×m
Or, 0.02×n = 0.02×m
Or, 
= 
∴ = 1
I.e m = n
Hence The relation between m and n is , m = n Answer
