Answer:

Average range(R-bar) = Sum of the sample range for each sample/number of samples = (9+8+1+8+7) /5 = 33/5 = 6.6

Sample size = 8

For a sample size of 8 the factors for control limit for range (D3) = 0.136 (obtained from table of constraints for x-bar and R chart

LCL = R-bar × D3 = 6.6 × 0.136 = 0.90

I NEED HELP ASAPP!!!

Llana [10]

Answer:

Step-by-step explanation:

$x - 2y = -8 \\y = 5x-2$

$x - 2 y = - 8$

add -x to both sides

$x - 2y - x = -8 - x \\- 2y = -8 - x$

multiply both sides by -1/2

$-2y * (\frac{-1}{2} ) = (-8-x) (\frac{-1}{2} )$

$y = 4 + \frac{x}{2} \\y = \frac{x}{2} + 4$

the equations don't have the same slope so they aren't parallel

The solpes product doesn't equal -1 so they aren't perpendicular
