Suppose that a process is currently operating at a 3.5-sigma quality level, and it is planned to use improvement projects to mov

jenyasd209 [6]

Answer:

$11,373 PPM$

Step-by-step explanation:

The following formula is used to compute the Proportion of error-free units given the sigma level in Excel.

The proportion of error-free units = NORMSDIST(Sigma Level - 1.5)

Suppose that a process is currently operating at a 3.5-sigma quality level.

The proportion of error-free units for this process is

NORMSDIST(3.5 - 1.5) = 0.977250

Therefore, the rejection rate is equal to

$1 - 0.977250 = 0.022750$

or 22750 PPM.

Now, consider a 6-sigma level process.

The proportion of error-free units equals

NORMSDIST(6.0 - 1.5) = 0.9999966

and the rejection rate is

$1 - 0.9999966 = 3.4 PPM$

Hence, reduction is PPM required per year , that is

$\dfrac{22750 - 3.4}{2} = 11,373 PPM$

reduction per year

Find the coordinates of the point three tenths of the way from A(-4, -8) to B(11, 7)

Leviafan [203]

let's first off take a peek at those values.

let's say the point with those coordinates is point C, so C is 3/10 of the way from A to B.

meaning, we take the segment AB and cut it in 10 equal pieces, AC takes 3 pieces, and CB takes 7 pieces, namely AC and CB are at a 3:7 ratio.

$\bf ~~~~~~~~~~~~\textit{internal division of a line segment}
\\\\\\
A(-4,-8)\qquad B(11,7)\qquad
\qquad \stackrel{\textit{ratio from A to B}}{3:7}
\\\\\\
\cfrac{A\underline{C}}{\underline{C} B} = \cfrac{3}{7}\implies \cfrac{A}{B} = \cfrac{3}{7}\implies 7A=3B\implies 7(-4,-8)=3(11,7)\\\\[-0.35em]
~\dotfill\\\\
C=\left(\frac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \frac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)\\\\[-0.35em]
~\dotfill$

$\bf C=\left(\cfrac{(7\cdot -4)+(3\cdot 11)}{3+7}\quad ,\quad \cfrac{(7\cdot -8)+(3\cdot 7)}{3+7}\right)
\\\\\\
C=\left( \cfrac{-28+33}{10}~~,~~\cfrac{-56+21}{10} \right)\implies C=\left( \cfrac{5}{10}~~,~~\cfrac{-35}{10} \right)
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
~\hfill C=\left( \frac{1}{2}~,~-\frac{7}{2} \right)~\hfill$
