The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The Margin of error in this survey is 1%.
<h3>What is the margin of error?</h3>
The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The random sample of 2500 sports fans, out of which 61% prefer basketball over soccer, therefore, we can write n=2500 and p=0.61. Thus, the margin of error can be written as,
Hence, the Margin of error in this survey is 1%.

Answer:
125
Step-by-step explanation:
total earning = 500
saving = 200
reaminings = 500-200
temainings= 300
vehical expenses=100
now remainings= 300-100
remaining=200
closing= 75
remaings=200-75
remainings for entertainment= 125

Answer:
8+2z
Step-by-step explanation:
8+(3z-z=2z)=
8+2z
If two angles are supplementary, then they add up to 180.
Angle 1 = twenty less than four times the other angle
Angle 2 = the other angle
Angle 2 = 1x
Angle 1 = 4x - 20
Next, we can add up angles 1 and 2 and set the sum equal to 180.
x + 4x - 20 = 180
5x - 20 = 180
5x = 200
x = 40
Now that we know x, we can find the values of our angles.
Angle 1 = 4(40) - 20 = 160 - 20 = 140 degrees
Angle 2 = 40 degrees
Hope this helps!! :)
