6 = 3( + -4) + -1

:

6 = 3(-4 + ) + -1

6 = (-4 * 3 + * 3) + -1

6 = (-12 + 3) + -1

: 3 + -1 = 2

6 = -12 + 2

6 = -12 + 2

''.

, .

'-2' .

6 + -2 = -12 + 2 + -2

: 6 + -2 = 4

4 = -12 + 2 + -2

: 2 + -2 = 0

4 = -12 + 0

4 = -12

'4'.

= -3

= -3

the data of the detroit pistons in numerical order from least to greatest is 0.30, 0.37, 0.55, 0.62, 0.69, 0.72, 0.73, 0.75, 0.77, 0.78, 0.80, 0.81, 0.81, 0.83, 0.84, 0.89

the data of the miami heat in numerical order from least to greatest is 0.50, 0.50, 0.56, 0.57, 0.67, 0.72, 0.72, 0.72, 0.75, 0.75, 0.76, 0.81, 0.82, 0.90, 1.00, 1.00

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
