Answer:
4
Step-by-step explanation:
The lowest common denominator for 1/2 and 1/4 is also the lowest common multiple of 2 and 4. Since 4 is a multiple of 2, 4 itself is the lowest common multiple.
1/4 would remain, and 1/2 would be written as 2/4.

every number 5 and over, you round it one number up. if youre rounding the thousands place, look at the hundreds place. if its 5 or over you round the thousands number up one then add the zeros.
Answer:
Rate in still water = 27.5 mph
Current's rate = 12.5 mph
Step-by-step explanation:
Let
x mph = row team rate in still water
y mph = current's rate
<u>Upstream:</u>
Distance = 30 miles
Time = 2 hours
Rate = x - y mph
Then
<u>Downstream:</u>
Distance = 30 miles
Time = 45 minutes 
hour
Rate = x + y mph
Then
From the first equation:
From the second equation:
Add these two equations:
Subtract these two equations:
Using the interpretation of the confidence interval, the correct option is:
We are 95% confident that those who studied had a higher passing rate than those who did not study.
<h3>What is the interpretation of a x% confidence interval?</h3>
It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.
The confidence interval of the difference is:
(0.005, 0.125).
Since the entire interval is positive, the correct option is:
We are 95% confident that those who studied had a higher passing rate than those who did not study.
