Answer:
In statistics, the three most common measures of central tendency are the mean, median, and mode. Each of these measures calculates the location of the central point using a different method.
Answer:
x = 5 , y = -1
Step-by-step explanation:
x + 2y = 3........(equation 1)
x - y = 6..........(equation 2)
make x the subject of the formula in (equation 1)
x = 3 - 2y
substitute for x in (equation 2)
3x - y = 6
(3- 2y) - y = 6
3 - 2y - y = 6
3 - 3y = 6
-3y = 6 - 3
substitute for y in (equation 1)
x = 3 - 2y
x = 5
Ok here is what I think.
Let us first number these statements, as #1, and #2.
First statement: 3x + 8y = 12 (1)
Second Statement: 2x + 2y = 3 (2)
Now, we can work from this.
We want to make one of the equations be equal to 0 so that at the end when we check they can be equal to each other.
Let us use 4.
3x+8y=12 1-8x-8y=-12 2
This gives us:-5x = 0
Now we should try and isolate x so we can substitute it into one of the equations.
We have -5x=0
and x=0
3(0)+8y=12
8y=12
y=12/8
y=3/2
Plug in these new equations
y=3/2 and y=0 into any of the first equations
3x+8y=12 3(0)+8(3/2)= 12 8(3/2)=12 4(3)=12 12=12
Now we know it works, thats our check^^
