Answer:
C
Step-by-step explanation:
Anything multipled by 6 will always be even, and anything multiplied by 4 will also always be even. Therefore, when we multiply (6x to the 4th)(4x to the 3rd), the answer will be even. However, 3 is odd, and an even number minus an odd number is ALWAYS odd.
In the given question, there are several important information's that needs to be noticed. based on these information's the correct answer to the question can be easily deduced. It is already known that the contestants rest for the same amount of time every hour. In 6 hours they rest for 27 minutes. The 6 hours has to be converted to minutes first.
Then 6 hours = (6 * 60) minutes
= 360 minutes
So we have to first determine the amount of rest each contestants take in 1 hour.
Then
In 360 minutes the couple rests for a total time = 27 minutes
In 60 minutes the couple will rest for = (27/360) * 60
= 4.5 minutes
So the couple rests for 4.5 minutes in 1 hour
Then
In 8 hours the couple will rest for = (8 * 4.5) minutes
= 36 minutes.
The couple will rest for 36 minutes in 8 hours.
Answer:
A recent study shows that about 43% of medical doctors have a solo practice with a margin of error of 4.6 percentage points.
Step-by-step explanation:
Given that a random sample of 311 medical doctors showed that 135 had a solo practice.
Sample proportion = 0.43
Std error of sample proportion = 
Margin of error 90% 
Margin of error in percent = 4.6%
Hence correction option is:
A recent study shows that about 43% of medical doctors have a solo practice with a margin of error of 4.6 percentage points.
