Answer:
B
Step-by-step explanation:
recall that any radical expression 
has real solutions only if A is not negative. (otherwise you will have imaginary solutions)
hence in this case we have
,
for real solutions, 8x must be ≥ 0,
since 8 is a positive number, x must be ≥ 0 (answer)

Answer:
Step-by-step explanation:
The null hypothesis is usually the default statement. The alternative is the opposite of the null and usually tested against the null hypothesis
In this case study,
The null hypothesis in would be that the mean time between clicks of the second hand on a particular clock is 1 second. In symbolic form it would be u = 1
The alternative hypothesis would be that the mean time between clicks of the second hand on a particular clock is 1 not second. In symbolic form, it would be: u =/ 1
Answer:
Option 3: 1 Hour 37 Minutes
Step-by-step explanation:
The start clock is at 12:47. The end clock is at 2:24. 12:47 + 37 minutes brings us to 1:24, then add 1 hour and you'll be at 2:24. So your answer should be 1 hour 37 minutes
