So to get 100 from 50, we’d have to do 50*2. So the bottom box/missing denominator would be 2, and since we have to find the perfect, the top box would also have to be 2 so the actual number doesn’t change. (2/2 = 1, anything multiplied by 1 is itself). We want it to look different and to be out of 100 but it should still hold the same value if that makes sense. So you do that and you do 27*2 which is 54, and the percent would be 54%

Let me know if you have any questions

Answer:

22 minutes

Step-by-step explanation:

Then you take that number and divide it by the cents per minute.

$2.64 ÷ 12 = 0.22

Then that's your answer!

Her call lasted 22 minutes.

Which of the following represents the correct calculation of the sampling interval?

Goshia [24]

Answer:

The correct answer is

d. Sampling Interval = Population size ÷ Sample size.

Step-by-step explanation:

According to Johnstone et al., (2014) "<em>Once the auditor has determined the appropriate sample size, a sampling interval is calculated by dividing the population size by the sample size.</em>"

Thus,

Sampling Interval = Population size ÷ Sample size.
