Answer:
The percent of the area under the density curve where 
is more that 3 is 25 %.
Step-by-step explanation:
Since the density curve is a linear function, the area under the curve can be calculated by the geometric formula for a triangle, defined by the following expression:
(1)
Where:
- Area, in square units.
- Base of the triangle, in units.
- Height of the triangle, in units.
The percent of the area is the ratio of triangle areas under the density curve multiplied by 100 per cent, that is:
The percent of the area under the density curve where is more that 3 is 25 %.
I think you mean circumference, which is equal to = 2πr

Answer:
34 minutes
Step-by-step explanation:
Given
Required
Number of minutes left to spend (x)
Since there's only 1 minute left to spend on every other call;
Time left = x * 1
Time left = x
The required can further be calculated using:
This gives:
Subtract 6 from both sides
<em>Hence, there are 34 minutes left to spend</em>
