The mean number of daily surgeries at a local hospital is 6.2. Assume that surgeries are random, independent events. (a) The cou
Wewaii [24]

Answer:

1)  Poisson distribution with mean 6.2 and standard deviation 2.49.

2) 0.0536

Step-by-step explanation:

We are given the following information in the question:

Mean of daily surgeries = 6.2

a) The count of daily surgeries can be treated as a Poisson distribution.

  • The Poisson distribution is the discrete probability distribution of the number of events occurring in a given time period, given the average number of times the event occurs over that time period.
  • The variance of Poisson distribution is equal to the mean of Poisson distribution.

Variance = 6.2

Standard deviation = \sqrt{6.2} = 2.49

a) Poisson distribution with mean 6.2 and standard deviation 2.49.

2) P( 2 or less surgeries)

Formula:

P(X =k) = \displaystyle\frac{\lambda^k e^{-\lambda}}{k!}\\\\ \lambda \text{ is the mean of the distribution}

P( x \leq 2) = P(x =0) + P(x=1) + P(x=2)\\\\= \displaystyle\frac{6.2^0 e^{-6.2}}{0!} + \displaystyle\frac{6.2^1 e^{-6.2}}{1!} + \displaystyle\frac{6.2^2 e^{-6.2}}{2!}\\\\ = 0.00203+ 0.01259 + 0.03900\\\\= 0.0536 = 5.36\%

What is 4.22 x 10^17 seconds
Allushta [10]

We can rewrite the given time as:

  • 7.03x10^15 mins
  • 1.17x10^14 hours.
  • 4.88x10^12 days.
<h3>What is 4.22x10^17 seconds in minutes and hours?</h3>

First, remember that:

60s = 1 min

Then to write that amount in minutes, we just need to divide by 60, so we get:

(4.22x10^17)/60  mins=  7.03x10^15 mins

Now, remember that:

1 hour = 3600s

Then to get the time in hours, we need to divide by 3600:

(4.22x10^17)/3600 h = 1.17x10^14 hours.

Similarly, you can change to any time unit that you want, for example:

1 day = 24*3600 s

Then the time in days is:

(4.22x10^17)/(24*3600) days = 4.88x10^12 days.

And so on.

Problem asked——Find a quick and easy method to compute the sum of the first 100 counting numbers. No calculators allowed.
Darya [45]

Answer

Step-by-step explanation:

split the numbers into two groups (1 to 50 and 51 to 100), he could add them together vertically to get a sum of 101.

1     + 2   + 3   + 4   + 5   + … + 48 + 49 + 50

100 + 99 + 98 + 97 + 96 + … + 53 + 52 + 51

1 + 100 = 101

2 + 99 = 101

3 + 98 = 101

.

.

.

48 + 53 = 101

49 + 52 = 101

50 + 51 = 101

Final total would be 50(101) = 5050.

50 addition problems all adding up to 101 thats how i got 50x101
