Answer:

About 2,800 hours of sleep per year

Step-by-step explanation:

Sleep per day= 7 hours 45 minutes

7 hours 45 minutes=465 minutes

Sleep per day =465 minutes

Sleep per year=365 days × 465 minutes

=169,725 minutes

There are 60 minutes in one hour

Divide 169,725 by 60 minutes

We have,

169,725/60

=2828.7500000 hours

Total sleep in a year is about 2,800 hours

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

Find the average rate of change.
alina1380 [7]

The average rate of change = 1.59 ≈ 2

The average rate of change can be calculated by

1) The first one = \frac{3 + 0}{2} = 1.5

2 ) the second can also be solved by ; 8 + 2/ 2 = 5

3 ) the third one will be 20 + 6 / 2 = 13

4) 8.5

5) 12.5

To calculate the average rate of change

we will first add all the distance

Adding all the distance we will get the sum = 3 + 8 + 20 + 10 + 10 = 51

The total time = 2 + 6 + 9 +15 = 32

Thus the average rate of change = 51 / 32 = 1.59
