Answer:
29000 - 24360 = $4,640
Step-by-step explanation:
23/10 = 2.3 pages per minute.
23. 1
10 = x
23x = 10
X = 10/23 of a minute per page.
Answer: (0.4247,0.7753)
Step-by-step explanation:
Given : Sample size : n=30
Number of people graduated from a registered welding course =18
The probability of people graduated from a registered welding course :
Significance level : 
Critical value : 
A confidence interval for population proportion is given by :-

Hence, the 95 percent confidence interval for the proportion of all welders who graduated from a registered welding course = (0.4247,0.7753)
Answer:
the parameter equation of given line is
x= 1+t
y=0+ 2t
z= 9+t
( note: in plane no signs given so we assume + so x+2y+z)
Step-by-step explanation:
A vector perpendicular to the plane a
x
+
b
y

c
z

d
=
0 is given by ⟨
a
,
b
,
c
⟩
So a vector perpendicular to the plane x
+2
y
+ z
− =

⟩
The parametric equation of a line through
and parallel to the vector ⟨
a
,
b
,
c
⟩ is

so the parametric equation of our line is

The vector form of the line is
