Answer:
b) 10 to 20
Step-by-step explanation:
You have to multiply each of the given numbers by 4, and add 8 to that result.
So:
And 60 is between the result of <u>10 and 20</u>, so that's the interval you have to select.
<em>The correct answer is b) 10 to 20</em>
Answer:
Mean=685
Variance=36.7
Step-by-step explanation:
The mean of uniform discrete distribution can be expressed as the average of the boundaries
mean=( b+a)/2
The variance of uniform discrete distribution can be expressed as the difference of the boundaries decreased by 1 and squared, decreased by 1 and divided by 12.
σ²=[(b-a+1)^2 - 1]/12
We were given the wavelength from from 675 to 695 nm which means
a= 675, b= 695
We can now calculate the mean by using the expresion below
mean=( b+a)/2
Mean=( 675 + 695)/2
=685
The variance can be calculated by using the expression below
σ²=[(b-a+1)^2 - 1]/12
σ²=[(695-675+1)^2 -1]/12
σ²=440/12
σ²=36.7
Therefore, the the mean and variance, of the wavelength distribution for this radiation are 685 and 36.7 respectively
Hello!
First you have to find the area of the space
300 * 500 = 150000
Next you have to find the space 5 people take up
5 * 5 = 25
Divide these two numbers
150000 / 25 = 6000
multiply this by the amount of people take up that space
6000 * 5 = 30000
The answer is D)30,000 people
Hope this helps!
The answer is 9.
6x4=24
?x4=36
