Small boxes of NutraFlakes cereal are labeled "net weight 10 ounces." Each hour, a random sample of 6 boxes is weighed to check process control. Five hours of observations yielded the following sample information. Construct a 3-sigma R chart. What does the chart tell you? Hour 1 2 3 4 5 Sample mean (x-bar) 10.5 10.0 9.6 10.5 9.4 ∑x-bar =50.0 Sample range (R) 0.8 1.2 0.9 0.6 0.5 ∑R =4.0

sorry not sure

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
