Find the slope of the line that passes through (-1, -1) and (91, 93).

alexandr402 [8]

Answer:

= 47/46

Step-by-step explanation:

Given two points on a line, we use the following formula to find the slope

m = (y2-y1)/(x2-x1)

= (93- -1)/(91 - -1)

= (93+1)/(91 +1)

= 94/92

Divide the top and bottom by 2

= 47/46

lawyer [7]

Don't listen to the guy below me haha <span> f(h) = 7.5x where you input h for x

so
f(15) = 7.5(15)
f(20) = 7.5(20)
f(25) = 7.5(25) </span>

the local store is having a sale on ground beef- $10 for 3 pounds. sylvia needs 12 pounds of meat to make 50 hamburgers. how muc

Rashid [163]

10/3 = x / 12.....$ 10 to 3 lbs = $ x to 12 lbs
cross multiply
3x = 120
x = 120/3
x = 40....so it is gonna cost Sylvia $ 40 for the meat.

she plans on making 50 burgers......40 ($ worth of meat) / 50 (burgers) =
0.8....so for each burger, the meat will cost 0.80 or 80 cents <==

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.

<em> The proportion of error-free units = NORMSDIST(Sigma Level - 1.5) </em>

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
