Let X be the number of lightning strikes in a year at the top of particular mountain.
X follows Poisson distribution with mean μ = 3.8
We have to find here the probability that in randomly selected year the number of lightning strikes is 0
The Poisson probability is given by,
P(X=k) = 
Here we have X=0, mean =3.8
Hence probability that X=0 is given by
P(X=0) = 
P(X=0) = 
P(X=0) = 0.0224
The probability that in a randomly selected year, the number of lightning strikes is 0 is 0.0224
Answer:
George made the first mistake by multiplying by 7 instead of 8
Step-by-step explanation:
The total cars needed to have a mean of 24:
24 x 8 = 192
Total cars sold during the seven months:
18 + 22 + 26 + 12 + 25 + 20 + 19 = 142
Subtract the total cars sold from the total cars needed:
192 - 142 = 50
George needs to sell 50 cars in the eight month in order to have an average of 24 cars sold per month.
Answer:
The answer is A so put it
For this case we have the following function:
![s (V) = \sqrt [3] {V}](https://tex.z-dn.net/?f=s%20%28V%29%20%3D%20%5Csqrt%20%5B3%5D%20%7BV%7D)
This function describes the side length of the cube.
If Jason wants a cube with a minimum volume of 64 cubic centimeters, then we propose the following inequality:
![s \geq \sqrt [3] {64}](https://tex.z-dn.net/?f=s%20%5Cgeq%20%5Csqrt%20%5B3%5D%20%7B64%7D)
Rewriting we have:
![s \geq \sqrt [3] {4 ^ 3}\\s \geq4](https://tex.z-dn.net/?f=s%20%5Cgeq%20%5Csqrt%20%5B3%5D%20%7B4%20%5E%203%7D%5C%5Cs%20%5Cgeq4)
Answer:
Option B
Answer:
If log x = 2
x = 100
Step-by-step explanation:
Logarithm always has a base and an index. It can be I many forms.
It can be in base 2, 3, 4, 5, and so on.
It is a property of logarithm that if
logarithm of 'a' to base 'b' equals 'x', we write:
log_b (a) = x
Then,
a = b^x.
Usually, when a logarithm is written without a base, it tells us that it is in base 10. Instead of writing a logarithm of x to base 10,we can just write 'log x', it is sufficient to say that it is in base 10.
It can also be in the form of the Napierian Logarithm, 'ln'.
'ln x' is logarithm to base 'e'.
if ln x = 5
Then
x = e^5.
So,
log x = 2
Means logarithm of 'x' to base 10 equals 2.
x = 10^2
= 100
x = 100
