The median is the middle of a list of numbers from least to greatest.
I will set up the numbers from least to greatest for you.
5, 6, 6, 8, 9.
To determine the median, cross out the smallest number with the largest number until you can no longer do so.
5, 6, 6, 8, 9.
6, 6, 8.
6.
Your median is 6.
I hope this helps!
Answer:
Express your answer using positive exponent.
adding power of common term and multiply constant term:
we know that
<u>The correlation coefficient</u> is a measure of linear association between two variables. Values of the correlation coefficient are always between −1 and +1.
Using a mathematical tool-------> Excel software
Find the correlation coefficient
see the attached table N 1 and N 2
the answer is
Part 1) The correlation coefficient of the data is 0.02
Part 2) The correlation coefficient of the data is 0.98
SOLUTION:
Let unknown number = x
x + 19 = 8
x = 8 - 19
x = - 11

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
x + 5y = 0
3y + 2x = -21
<u>Step 2: Rewrite Systems</u>
x + 5y = 0
- Subtract 5y on both sides: x = -5y
<u>Step 3: Redefine Systems</u>
x = -5y
3y + 2x = -21
<u>Step 4: Solve for </u><em><u>y</u></em>
<em>Substitution</em>
- Substitute in <em>x</em>: 3y + 2(-5y) = -21
- Multiply: 3y - 10y = -21
- Combine like terms: -7y = -21
- Isolate <em>y</em>: y = 3
<u>Step 5: Solve for </u><em><u>x</u></em>
- Define equation: x + 5y = 0
- Substitute in <em>y</em>: x + 5(3) = 0
- Multiply: x + 15 = 0
- Isolate <em>x</em>: x = -15
