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

write the slope - intercept equation of the line that passes through the point (6, "-1)" and has a slope of "-1/3"
andreev551 [17]

Answer:

-1 = 1/3 * 6 - 3

Step-by-step explanation:

So if it goes through point (6, -1) and has a slope of -1/3, all of this is parts of the slope intercept equal, Y = mx - B. You have the slope, which is m in the equation, y = -1/3 x - b. you already have a y and x which are the points passed, -1 = -1/3 * 6 - b, but this can't equal y, so you must have did it wrong, the only way this could equal y is if the slope wasn't negative, and in that case it would be -1 = 1/3 * 6 - 3. Because 1/3 * 6 is 2 and then subract 3 and you get -1.

A triangle is removed from the rectangle. Find the area of the remaining figure.
Mariulka [41]

Answer

C) 160 in^2


Step by step explanation

First, let's find the area of the rectangle.

Area of a rectangle = length x width

The area of the rectangle = 20 * 10

= 200 in^2

Now let's find the area of the triangle that is removed.

Area of a triangle = 1/2 base * height.

Here base = 10 and height = 8. Plug in these values into the formula, we get

Area of the triangle = 1/2 * 10*8

= 5* 8

The area of the triangle = 40 in^2

The area of the remaining figure = Area of the rectangle - area of the triangle

=  200 - 40

= 160 in^2

The answer is "160 in^2"

Thank you.
