Answer:
By making use of a lower confidence level
Step-by-step explanation:
The margin of error is also referred to as the confidence interval and it is the system in which we use to measure the error in the result of the survey or experiment.
Now, for us to reduce the margin of error, there are different things we can do such as;
- increasing sample size
- using less data variation
- making use of a lower confidence level
- making use of a one sided confidence interval rather than a two sided confidence interval.
Looking at the above different methods of making the margin of error smaller, the one that is always under the control of the researcher is "making use of a lower confidence level".
Every other means, he does not have as much control as he has to do to lower the confidence level. That one is strictly based on his jurisdiction.
Answer:
A triangle has side lengths 10 feet, V205 feet, and V105 feet
Step-by-step explanation:
8 1/2=17/2=8.5
24,700 divided by 8.5=2,905,8823
OR
24,700:17/2 =24,700x2/17=2,905,8823
Answer:
4'9"
Method 1:
First, convert both numbers into inches. Remember that 1' = 12", and the rest is like a remainder.
7'5" = (7*12)+5 = 84+5 = 89
2'8" = (2*12)+8 = 24+8 = 32
Next, subtract the two numbers.
89 - 32 = ?
89 - 32 = 57
There's your answer! You can change it back into feet by dividing it by 12.
57 / 12 = 4.75 = 4'9"
Method 2:
Another way of solving this problem is to borrow from the "feet" place.
7'5" - 2'8"
You can't take 8 away from 5, so you borrow from the "feet" place. Remember that unlike normal borrowing, you need to add 12 instead of adding 10.
6'17" - 2'8" = 4'9"
Whichever method you choose, you should get the same answer!
