Answer:
f=4
Step-by-step explanation:
-11f = 7(1-2f)+5
step 1 distribute what is outside of the parenthesis to the inside of the parenthesis
-11f=7-14f+5
step 2 combine like terms
-11f=12-14f
step 3 add 14 to each side
3f=12
step 4 divide each side by 3
f=4
Answer:
W =1 1/4Step-by-step explanation:
Let W = what
W - 1/2 = 3/4
Add 1/2 to each side
W -1/2 +1/2 = 3/4+1/2
W = 3/4+1/2
Getting a common denominator of 4
W =3/4+1/2*2/2
W =3/4 +2/4
W = 5/4
Changing to a mixed number
W = 4/4 +1/4
W = 1 +1/4
W =1 1/4
2x + 3y = 23...........................(1)
3x - y = 7 Multiply by 3:-
9x - 3y = 21 Adding this to equation (1):-
11x = 44
x =
Plug this into equation (1):-
2(4) + 3y = 23
3y = 15
y = 5
Answer is x = 4, y = 5

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
