Answer:
v=a+ 2e1= [3 1 1 1] 
.
Step-by-step explanation:
Let a = 
![\left[\begin{array}{ccc}\\1&1&1\\\end{array}\right] ^{T}](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%5C%5C1%261%261%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%5E%7BT%7D)
and we know that
=±║α║₂= 2.
As we have gone over in class, the formula for v is v= a-e1
with the sign of chosen to avoid subtraction. This gives v=a+ 2e1= [3 1 1 1] .

Answer:
Option C is correct.
Step-by-step explanation:
Number of students of Deerlake middle school that voted = 442
Percentage of student that voted = 76%
Let x be the total number of student.
According to the Question,
Therefore, Option C is correct.
The proportion would be the number of the sample (x) over the population size (n)
Here we have x = 59,969 and n= 461,299
P = x/n = 59969/461299
P = 0.13
We need to get x alone, to do that we add 1 to both sides to cancel out the -1 on the right.
-4 = x -1
+1 +1
-3=x
This means x is equal to -3. Hope this helps!
