Answer :
<h3>The average of a distribution is equal to the summation of x divided by the number of observations is called <u>Mean</u></h3>
Step-by-step explanation:
<h3>The average of a distribution is equal to the summation of x divided by the number of observations is called <u>Mean</u></h3><h3>For :</h3>
- We know that

where N is the number of observations
<h3>Therefore the average of a distribution is known as Mean.</h3>
Answer:
see below
Step-by-step explanation:
1st: x
2nd: 5x + 8
x(5x + 8) = 36
5x² + 8x = 36
5x² + 8x - 36 = 0
(x - 2)(5x + 18) = 0
(x - 2) = 0
x - 2 = 0
x = 2
1st: x = 2
2nd: 5x + 8 = 5(2) + 8 = 18
(5x + 18) = 0
5x + 18 = 0
5x = -18
x = -3.6
1st: x = -3.6
2nd: 5x + 8 = 5(-3.6) + 8 = -18 + 8 = -10
1x100,000 = 100,000
3x10,000 = 30,000
9x1,000 = 9,000
8x100 = 800
5x10 = 50
2x1 = 2
Add these all together to get your answer. Standard form is the form we usual write numbers in.
I would do linear combinations
if we simplify all of them by dividing the 2nd equation by -2 and the 3rd by 3, we get
x+y+2z=5
x+y+2z=5
x+y+2z=5
which is all the same plane, so there are infnitely many solutions
