The equation of variation in which y varies jointly as x and z and inversely as the product of w and p is y=0.5(xz/wp).
Given that variable y varies jointly as x and z and inversely as the product of w and p,where y=7/28 where x=7,z=4,w=7 and p=8.
We are required to find the equation of variation.
To solve this problem we must apply the following procedure:
1) We have that y varies jointly as x and z and inversely as the product of w and p. Therefore we can write the following equation,where k is the constant of proportionality:
y=k(xz/wp)----------1
Now we have to solve for the constant of proportionality as done under:
k=ywp/xz-------------2
Using the values in equation 1.
k=(7/28)(7)(8)/(7)(4)
=0.5
Using all the values in the equation 2.
y=0.5(xz/wp)
Hence the equation of variance is y=0.5(xz/wp).
Question is incomplete.The following values should be included:
y=7/28 where x=7,z=4,w=7 and p=8.

Answer:
I need more information to solve this problem
Option D : 54 is the range of the distribution
Explanation:
The given distribution is 21, 32, 49, 67, 75
The range of the distribution is the difference between the highest value and the lowest value in the distribution.
From the given data, we can see that,
Highest value = 75
Lowest value = 21
The range can be determined by subtracting by the highest value and the lowest value.
Thus, we have,
Range = Highest value - Lowest value
Range = 75 - 21
Range = 54
Thus, the range of the given distribution is 54.
Hence, Option D is the correct answer.
Answer:
I = 1.47001
Step-by-step explanation:
we have the function

In polar coordinates we have

and dA is given by

Hence, the integral that we have to solve is

This integral can be solved in a convenient program of your choice (it is very difficult to solve in an analytical way, I use Wolfram Alpha on line)
I = 1.47001
Hope this helps!!!
2x + 3x + x + 60= 180
6x + 60= 180
6x° = 120°
x° = 20°
(2x)°= 40°
(3x)°= 60°
(x+60)°= 80°
