Answer: 0.2119
Step-by-step explanation:
We assume that the random variable X is normally distributed.
Given : Population mean :
Standard deviation :
Z-score :
Then, z-score corresponds to 116
By using the standard normal distribution table for z , we have
Hence, the required probability = 0.2119
Answer:
6-2y=4y+8
since you show x through y
Answer:
The result that is obtained on comparing the system of equations in order to get the solution to the system of equations is:
6 -2y =4y + 8
Step-by-step explanation:
We are given a system of equations in term of variable x and y as follows:
x + 2y = 6 --------(1)
x - 4y = 8-------------(2)
From equation (1) we have the value of x in terms of y as:
x=6-2y
From equation (2) we have the value of x in terms of y as:
x=8+2y
Hence, on equation the above two values of 'x' we obtain:
6 - 2y = 4y + 8

Answer:
(a) 720 ways
(b) 120 ways
(c) 24 ways
Step-by-step explanation:
Given
--- number of letters
Solving (a): Number of arrangements.
We have:
So, the number of arrangements is calculated as:
This gives:
This gives:
Solving (b): DA as a unit
DA as a unit implies that, we have:
[DA] N C E R
So, we have:
So, the number of arrangements is calculated as:
This gives:
This gives:
Solving (c): NCE as a unit
NCE as a unit implies that, we have:
D A [NCE] R
So, we have:
So, the number of arrangements is calculated as:
This gives:
This gives:
If the perimeter is 44 the the diagonal is 22
