Step-by-step explanation:
x+z = 1, z = 0
x + 0=1
x = 1
3x+3z= 3
3(1) + 3(0) = 3
3 = 3
Mean = (9.1 + 9.2 + 9.3 + 9.3 + 9.5 + 10.4 + 10.5 + 10.6 + 10.6 + 10.7 + 11.1 + 11.1 + 11.4 + 11.8 + 11.9 + 11.9 + 12.4 + 12.7 + 12.9)/19 = 196/19 = 10.3

Answer:
Step-by-step explanation:
The area of the rectangular window is equal to the product between the length of the window and its width:
(1)
where
A is the area
L is the length
W is the width
In this problem, the area of the glass window is
This can be rewritten as
(2)
The two expressions, in fact, are equivalent.
Also, we know that the width is
(3)
By comparing (1) with (2) and (3), we notice immediately that
Therefore, this is the length of the glass pane.
