Since children have a population of 3000 with 150 degrees
Divide both 150 and 3000 by 150 to get 1:20
Then multiply 20 with 360 to get the total population
Total Population: 7200
And since we have the ratio of degrees to population
We multiply 20 to the others to get
Number of Men: 1800
Number of Women: 2400
Answer:
x = 2.2, y = -1.8, z = -1.6
Step-by-step explanation:
Put the coefficients of each variable and their constants into a matrix, as shown below.
1 1 -1 2
2 1 1 1
2 -1 2 3
Now use the rref( function to essentially "solve" the equation for all of its variables. You end up with the following matrix:
1 0 0 2.2
0 1 0 -1.8
0 0 1 -1.6
Remember that the first three columns are the coefficients on our variables, and the last column is the constant on the other side. That means that this matrix is essentially telling us the value of each variable.
x + 0y + 0z = 2.2
0x + y + 0z = -1.8
0x + 0y + z = -1.6
