Answer:
22.09 ft²
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr² . . . . where r is the radius, half the diameter
The slice, at 45°, is 1/8 of the circle, so the area of the slice is ...
A = (1/8)π(15 ft/2)² = 225π/32 ft² ≈ 22.09 ft²
Answer:
The LCL of the R-chart starts from the origin ( i.e. zero value ) while the LCL of an X -chart did not start from the origin
LCL of R-chart = 0 * 0.84533 = 0
LCL of R-chart = 75.128
Step-by-step explanation:
Given data:
number of observations = 15
sample size ( m ) = 6
sum of sample mean = 80.20 ounces
sum of sample range ( R ) = 12.68 ounces
Determine the control limits of an x-bar and R-chart
<em>for an R-chart </em>
LCL of R-chart = D3 * R(bar) ---- ( 1 )
where : m = 6 , D3 = 0 , R = 12.68
R(bar) = 0.84533
back to equation 1
LCL of R-chart = 0 * 0.84533 = 0
<em>for an X-chart </em>
LCL of X-bar) = ( mean ) - (m x R-bar)
= 80.20 - ( 6 * 0.84533 )
= 75.128
The LCL of the R-chart starts from the origin ( i.e. zero value ) while the LCL of an X -chart did not start from the origin
Answer:
-9x+12
Step-by-step explanation:
(-8x + 5) - (x – 7)
Distribute the minus sign
(-8x + 5) - x + 7
Combine like terms
(-8x -x+ 5+7)
-9x +12
Answer:
D
Step-by-step explanation:
Perimeter: add all sides
2(4(2x+1))+2(3(x+4))
2(8x+4)+2(3x+12)
16x+8+6x+24
22x+32
Answer:
10 pounds (lbs.)
Step-by-step explanation:
If you have 2 containers with 5 pounds of clay each, the equation would be 2 times 5. 2 x 5 is 10. If there is more, we don't know this as of now. The problem says "atleast", so we can assume that Beth has a minimum of 10 pounds of clay.
