Answer:
(a) plane NOU
Step-by-step explanation:
The points identified on plane <em>L</em> are {M, N, O, U}. All but point U are on the same line.
To identify the plane we need to name 3 non-collinear points. U must be one of them. The other two could by any two from the set {M, N, O}.
One possible name for plane <em>L</em> is plane NOU.
Answer:
-1
Step-by-step explanation:
Slope formula: (y₂ - y₁) / (x₂ - x₁)
= (2 - 1) / (1 - 2)
= -1
Here given,
and 
we have to find
which means the subtracting of the functions f(x) and g(x).

= 
= 
=
( we know that multiplication of negative and negative is positive)
= 
=
We have got the required answer here.

Answer:
0.08065
Step-by-step explanation:
Given that in a recent study,1 2006 randomly selected US adults (age 18 or older) were asked to give the number of people in the last six months with whom you discussed matters that are important to you.
If X is random variable then X has mean 2.2 and s = 1.4
n=2006
Std error of mean =
For 99% since sample size is large, t and z distn almost coincide.
Hence we can take 2.58 as critical value
Margin of error at 99% =
