Answer:

42.3% or 11/26

Step-by-step explanation:

IN order to calculate the percentage of people that voted for Candidate A you just need to add up the number of votes for that candidate and then multiply it by 100 and divided by the total votes.

There were 26 voters, since there were 7 that didn´t vote for anyone, so we have that 11 voted for Candidate A:

\frac{11}{x} =\frac{26}{100}\\ x= \frac{11*100}{26}\\ x=42.30

So the percentage of voters that voted for candidate A was 42.3 percent.

In a triangle, the sides of triangles are completely depend on the interior of the triangle. In the triangle, the longest side has the largest opposite angle and the shortest side has the smallest opposite angle.

Arrange the sides of the triangle ACR in ascending order.

12

AR

It means the order of the opposite angles to sides is:

\angle C

Therefore, the list of angles in order from least to greatest is \angle C,\angle A,\angle R.

q=0.95

n=10400

np=10400*0.05=202\\npq =494

Var(x)=npq=494\\std dev=\sqrt{494} \\=22.23
