He started with 16 because he sold half so add half and that would be 16 ;)
240 students = 48% of total enrollment
48% means 0.48
"of" means "times" .
240 students = 0.48 x total enrollment
Divide each side by 0.48 :
Total enrollment = 240 students / 0.48 = <em>500 students</em>
The correct statement is test is reliable and authentic as the probability of no false positives is more than 0.5
Given that

Now following calculations to be done to reach out the conclusion
There is no false positive as
= 100 - 5.5
= 94.5%

Now

So
P value = P(z >3.08) = 0.0010
Therefore we can conclude that test is reliable and authentic as the probability of no false positives is more than 0.5

Answer:

Step-by-step explanation:
Given the solution to an inequality
{x|x>2/3}
The solution set does not include
, therefore, it must be open at the left. Recall that we use a curvy bracket ( to denote openness at the left.
Since x is greater than
, the solution set contains all values of larger than
up till infinity. Since infinity is an arbitrarily large value, we also use an open bracket at the right.
Therefore, another way to represent the solution {x|x>2/3} is:

The correct option is C.
