Answer: 0.3679

Step-by-step explanation:

The cumulative distribution function for exponential distribution is :-

P(x)=1-e^{-\lambda x}, where \lambda  is the mean of the distribution.

Given :  A mean length of waiting time equal 2.8 minutes

i.e. Mean number of calls answered in a minute \lambda=\dfrac{1}{2.8}

Now, the proportion of callers is put on hold longer than 2.8 minutes is given by :_

P(x>2.8)=1-P(x

Hence, the proportion of callers is put on hold longer than 2.8 minutes = 0.3679

Rasek [7]

Answer:

x=2\sqrt3\ km

Step-by-step explanation:

Given that,

The base of a triangle = 2 km

The perpendicular height of the triangle = 2\sqrt{2} \ km

We need to find the value of x. It is the Hypotenuse of the triangle. It can be solved as :

x=\sqrt{(2\sqrt{2})^2+2^2 } \\\\=2\sqrt{2+1 } \\\\=2\sqrt3\ km

So, the value of x is equal to 2\sqrt3\ km.
