Answer: 0.3679
Step-by-step explanation:
The cumulative distribution function for exponential distribution is :-
, where 
is the mean of the distribution.
Given : A mean length of waiting time equal 
minutes
i.e. Mean number of calls answered in a minute 
Now, the proportion of callers is put on hold longer than 2.8 minutes is given by :_
Hence, the proportion of callers is put on hold longer than 2.8 minutes = 0.3679
Volume = pi*r^2
so 58^2*pi= 3364pi = approx 10,562.96 in^2
3-2y-8x is it's most simplified form I think.
The smaller triangle is 1/6 the size of the large one ( 5/30 = 1/
Area is squared 1/6 ^2 = 1/36
Multiply the area of the large triangle by 1/36:
270 x 1/36 = 270 /36 = 7.5
The area is 7.5 cm^2
The answer is A.
Answer:
The slope seems to be 4.
Step-by-step explanation:
The line seems to be starting at (3,0) and if you use the rule rise/run, it goes up (rises) 4 units and moves over (runs) 1 unit. You then rewrite this as 4/1 and you get 4 as the slope!
