Answer:
The answer is B
Step-by-step explanation:
Definition of margin of error is simply expected error from result of a survey. Which means the actual vote results are in the range of plus or minus %3.
On this survey the result is %55 percent in favor of Taylor and the margin of error is %3. That means in the real election Taylor will get votes in between %52-%58. In other word

The sample proportion minus the margin of error is greater than 0.50, which provides evidence that more than half of all likely voters plan to vote for candidate Taylor.
The angles are 45° 60° and 75°
Elaboration:
Let the three angles be 3x 4x and 5x
( since the sum of interior angles of triangle=180° )
3x+4x+5x= 180
12x = 180
x = 15
3x= 45
4x= 60
5x= 75
Answer:
x >-11
Explanation:
2x+7>-15
Subtract 7 from both sides
2x >-15-7
Simplify-15-7 to -22
2x >-22
Divide both sides by 2
22
x > - ___
2
Simplify 22/2 to 11
x >-11

Assuming you are asking what does x represent when you say "What does represent" the answer is a: the number of days it take the brothers to paint 13 pictures.
The first 2 sentences are useless and don't tell you anything (well they do but you don't need the information).
Both brothers can paint 13 pictures in x days.
So x means days, more specifically, the number of days it took for the brothers to paint 13 pictures.

425.69+298.72=724.41
29.72+135.47+208.28=373.47
724.41-373.47=350.94
350.94-5=345.94
The answer is c
