Answer:
Factoring
Step-by-step explanation:
and 
Answer:
1/5
Step-by-step explanation:
F(x)=x^2
g(x)=1/(2x+3)
g(f(-1))=?
x=-1→f(-1)=(-1)^2→f(-1)=1
g(f(-1))=g(1)=1/[2(1)+3]=1/(2+3)→g(f(-1))=1/5
Answer:
D. 0.27
Step-by-step explanation:
An X-bar is a control chart used with processes that have a subgroup size of two or more. X - bar chart helps us to determine if a process is stable and predictable.It shows how the mean or average changes over time.
T o determine the A2 factor for the X-bar chart of a particular sample size, n, check the table of control chart constant.
For a sample size of 12, the A2 constant for the X-bar chart is 0.266
Let the width = x -12
the length = x
we have this area equation: x(x-12)=380.16
=>x^2-12x-380.16=0
=>(5x-132)(5x+72)=0
=>x= 132/5 and x= -72/5 (no)
=>The width of the poster is: 132/5 -12 =72/5 inches
