djyliett [7]
Enable to get the median. you have to put the numbers in order from least to greatest. Once you have done that, if there are two numbers in the middle, add them up and divide by 2.
your IQR is: 14.75

Solve the system by elimination (show all work)
Snezhnost [94]

Answer:

[1, 1, 0]

Step-by-step explanation:

{−2x + 2y + 3z = 0

{−2x - y + z = −3 ←

{2x + 3y + 3z = 5 ←

2y + 4z = 2 ↷

{−2x + 2y + 3z = 0 ←

{−2x - y + z = −3

{2x + 3y + 3z = 5 ←

5y + 6z = 5 ↷

{5y + 6z = 5

{2y + 4z = 2

−⅖[5y + 6z = 5]

{−2y - 2⅖z = −2 >> New Temporary Equation

{2y + 4z = 2

____________

1⅗z = 0

___ _

1⅗ 1⅗

z = 0 [Plug this back into both equations above to get the y-term of 1, then plugging both z-term and y-term into all three equations at the very top, will give you the x-term of 1]; 1 = y; 1 = x
