The number of errors in a textbook follow a poisson distribution with a mean of 0.01 errors per page. what is the probability th
neonofarm [45]
Mean number of errors in each page = 0.01
Mean number of errors in 100 pages = 0.01*100=1

It is possible to use the cumulative distribution function (CMF), but the math is a little more complex, involving the gamma-function.  Tables and software are available for that purpose.

Thus it is easier to evaluate with a calculator for the individual cases of k=0,1,2 and 3.

The Poisson distribution has a PMF (probability mass function) 
P(k):=\frac{\lambda^ke^{-\lambda}}{k!}
with λ = 1
=>
P(0):=\frac{1^0e^{-1}}{0!}=0.3678794
P(1):=\frac{1^1e^{-1}}{1!}=0.3678794
P(2):=\frac{1^2e^{-1}}{2!}=0.1839397
P(3):=\frac{1^3e^{-1}}{3!}=0.0613132
=>
P(k
or
P(k<=3)=0.9810 (to four decimal places)

Kumar the painter has 17 gallons of paints. He puts it into 6 buckets so each has the same amount. How many gallons are in each
9966 [12]

Answer:

17/6 or 2 5/6 gallons of paint

Step-by-step explanation:

First, do 17/6= 2 5/6.

That's really all, but I can't help you with the number line because of no attachment, but just put it on the part where it says 17/6 or 2 5/6.

Hope this helped!

Find sum of three consecutive even integers if the largest integer is Y
KATRIN_1 [288]

Answer:

3y -- 6

Step-by-step explanation:

if the largest number is y, then the other two integers would be (y -- 2) and (y -- 4).

Therefore the sum of the integers would be

y + (y -- 2) + (y -- 4) = 3y -- 6.

2. In the diagram below, set I represents rational numbers, set II represents integers, and set III represents whole numbers. Sh
MrRa [10]

The information about the rational numbers and integers shows that the correct option is C.

<h3>How to explain the information?</h3>

It should be noted that rational numbers are numbers where we can write as a fraction of two integers. Any rational number is in the form a/b where a,b are integers and b is nonzero.

Terminating decimals can be written as a rational number. Something like 3.1 is equivalent to 31/10.

Of the four answer choices, only choice C is correct.

Choice A has the value '3' as a rational number, but it doesn't have it in the set of integers as well. So that's why choice A is incorrect.

Choice B has -3.4 in the set of integers, which is not correct. Integers do not have any decimal portion. The same applies to choice D also. We can rule choices B and D out.

Therefore, the correct option is C.
