Answer:
Step-by-step explanation:
Length of the bridge = 190 m = 190*100 = 19000 cm {100cm = 1m}
Length of each pace of Robert = 80 cm
Minimum number of full paces = 19000/80
= 237.5
= 238 {because full paces}
So what you would do is 3000 divided by 150 which is 20 then you would multiply 20 by 2 which is 40 so 40 is most likely defective.
Answer:
3:2
Step-by-step explanation:
2x-y=1 is also equal to y=2x-1 so then plug in 1 or x and so on to create a table
The margin of error is ±2%
<h3>What is Margin error?</h3>
A margin of error is a statistical measurement that accounts for the difference between actual and projected results in a random survey sample.
Let x be margin of error and y be the percentages of the population.
So,
y-x =33%
y +x = 37%
Solving above equations
2y= 70
y= 35%
and x= 2%
Hence, the margin of error is ±2%.
