Suppose that you collect data for 15 samples of 30 units each, and find that on average, 2.5 percent of the products are defecti

ve. What are the UCL and LCL for this process? (Leave no cells blank - be certain to enter "0" wherever required. Do not round intermediate calculations. Round up negative LCL values to zero. Round your answers to 3 decimal places.)

Answer:

The  UCL  is  UCL  =  0.054

The LCL  is  LCL \approx 0

Step-by-step explanation:

From the question we are told that  

     The quantity of each sample is  n =  30

     The  average of defective products is  p  =  0.025

Now  the upper control limit [UCL] is  mathematically represented as

       

      UCL  = p +  3 \sqrt{\frac{p(1-p)}{n}  }

substituting values  

      UCL  = 0.025 +  3 \sqrt{\frac{0.025 (1-0.025)}{30}  }

      UCL  =  0.054

The  upper control limit (LCL) is mathematically represented as

       LCL  = p -  3 \sqrt{\frac{p(1-p)}{n}  }

substituting values  

      LCL  = 0.025 -  3 \sqrt{\frac{0.025 (1-0.025)}{30}  }

       LCL  = -0.004

        LCL \approx 0

What is the perimeter of the figure?​
rewona [7]

Answer:

Oh! We should start with finding the lngths of the "curvy sides". As you can see there are 2 semi circles which we can combine to make one circle with a diameter of 7. The formula for the circumference of the circle is 2πr which is also equal to the diameter x π. SO the circumeference is 7π which is this case equals 22 since they are telling us to use  π as 22/7. I'm not sure about the rest but I hope this helped a little!!

Starting with x=4.62 repeating express x as a fraction in simplest form
arsen [322]

x=4.62=4+0.62=4+\dfrac{62}{100}=4+\dfrac{62:2}{100:2}=4+\dfrac{31}{50}\\\\\text{as a mixed number}\ 4\dfrac{31}{50}\\\\\text{as an improper fraction}\ \dfrac{4\cdot50+31}{50}=\dfrac{231}{50}

The area of a rectangular concrete patio is 70 square meters. the perimeter is 34 meters. what are the dimensions of the patio?
Finger [1]
A = L * W
A = 70

70 = L * W

P = 2(L + W)
P = 34

34 = 2(L + W)
34/2 = L + W
17 = L + W
17 - W = L

70 = L * W
L = 17 - W

70 = W(17 - W)
70 = -W^2 + 17W
W^2 - 17W + 70 = 0
(W - 10)(W - 7) = 0

W - 10 = 0        L = 17 - 10
W = 10              L = 7

W - 7 = 0          L = 17 - 7
W = 7               L = 10

so either the width is 10 meters and the length is 7 meters OR the width is 7 meters and the length is 10 meters
