The weight of a bag of industrial salt needs to be monitored using control charts. Several samples were taken where fifteen bags were randomly selected. The average weight of the bag and range were calculated for each sample. Over all the samples, the average weight of the bag was found to be 400 ounces and the average range was found to be 25.50 ounces. What is the lower control limit of the - chart (i. e., x-bar chart)

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

answer

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
