Answer:
40cm
Step-by-step explanation:
volume of a cylinder= πr²h
V=24litres, Area=πr²=600cm², height=?
converting litres to cm³
1litre=1000cm³
24litres= 24×1000
=24000cm³
24000=600× h
h= 24000/600
= 40cm
The formula for the equation of a circle is (x - h)² + (y - k)² = r²
where (h, k) is the center of the circle and <em>r</em> is the radius.
So we need to find the values of (h, k) in order to find the center of the circle.
If we simply line up the equation of our given circle with our formula,
we can see that -h = 3 or h = -3 and -k = -2 so k = 2.
So now we have our answer.
center ⇒ (-3, 2)
Answer:
a) correct option is
Poisson distribution is 6.2 and standard deviation is 2.49
b) probability for only 2 or less than 2 surgeries in a given day is 0.0536
Step-by-step explanation:
Given data:
mean number is given as 6.2
correct option is
Poisson distribution is 6.2 and standard deviation is 2.49
we know that variance is given as![\sigma^2 = mean = 6.2](https://tex.z-dn.net/?f=%20%5Csigma%5E2%20%3D%20mean%20%3D%206.2)
hence, standard deviation is given as ![\sqrt{6.2} = 2.48998](https://tex.z-dn.net/?f=%5Csqrt%7B6.2%7D%20%3D%202.48998%20)
thus standard deviation is 2.49
correct option is
Poisson distribution is 6.2 and standard deviation is 2.49
b) probability for only 2 or less than 2 surgeries in a given day is
![P(X \leq 2) = P(X =0) + P(X =1) + P(X =2)](https://tex.z-dn.net/?f=P%28X%20%5Cleq%202%29%20%3D%20P%28X%20%3D0%29%20%2B%20P%28X%20%3D1%29%20%2B%20P%28X%20%3D2%29)
![= \frac{e^{-6.2} 6.2^0}{0!} +\frac{e^{-6.2} 6.2^1}{1!} +\frac{e^{-6.2} 6.2^2}{2!}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7Be%5E%7B-6.2%7D%206.2%5E0%7D%7B0%21%7D%20%2B%5Cfrac%7Be%5E%7B-6.2%7D%206.2%5E1%7D%7B1%21%7D%20%2B%5Cfrac%7Be%5E%7B-6.2%7D%206.2%5E2%7D%7B2%21%7D)
= 0.002029 + 0.012582+ 0.039006
= 0.053617
= 0.0536
