B -13 -34i
(7 + 2i)(-3 - 4i)
Take the 7 then times it buy the second bracket 7x(-3-4i) then take 2i from the first bracket and times it with the second bracket 2ix (-3-4i)
Then keep simplifying

What is the standard deviation of this sampling distribution?
Ď /âšn
= 60/âš840
=2.0702
b)
1 standard deviation of the mean
= (1) 2.07
= 2.07
c)
272+/- 1(2.07)
(269.93, 274.07)</span>
Personally if I would of put it in a fraction it be 2/10
Answer:
3,500 no votes
Step-by-step explanation:
There were 7 yes votes to every 4 no votes. There were a total of 6,125 yes votes, so set up a proportion to find the number of no votes
Let x represent the number of no votes
7 is to 4 as 6,125 is to x
We get
7/4 = 6,125/x
Now solve for x
First cross multiply
7x = 24,500
Divide both sides by 7 to isolate x..
x = 3,500 no votes
