This is a "simple random sample" problem in which we randomly select a sample from a larger population therefore everyone has same probability of being selected.

Total students: 250

Labeled as 001, 002, 003,.....250

The generated random number table is:

69041 65817 87174 09514 8174 06423 93758 23612 17894

Now we have to arrange/sort this random number table in groups of three numbers.

690, 416, 581, 787, 174, 095, 148, 174, 064, 239, 375, 823, 612, 178, 94

Now we have to select first 5 distinct numbers in the range of 001 to 250

The first four numbers (690, 416, 581, 787) are out of range so ignore them.

Next we find our first three numbers (174, 095, 148)

Next we have number (174) again that we have already selected so ignore it.

Next we find our fourth and fifth number (064, 239)

We are done with selecting 5 numbers and these are:

174, 095, 148, 064, 239

Answer:

Step-by-step explanation:

To start off this problem, we are given that the line AB is equal to the line CD. In addition to that, we are given that the line EF equally intersects line AB and line CD. This provides us proof that angle AGH is equivalent to angle DHG. From this information, we can solve this problem relatively easily.

Lets work with this equation:

$80 = 5x$

Next, divide 80 by 5.

$\frac{80}{5} =x$

$16 = x$

This means that x is equal to 16.
