At a large university, 20% of students are enrolled in the nursing program. The dean of students selects a random sample of 20 s

tudents and records n = the number of students enrolled in the nursing program. The dean decides to simulate this random process by using a random number table. He assigns the digits to the outcomes.
1 = student enrolled in nursing program

2–5 = student not enrolled in nursing program

Skip 6–9 and 0

How can the dean use a random number table to simulate one trial of this situation?

He can select a row of the random number table and read 20 single digits between 1 and 5. He will record the mean of the 20 digits.
He can select a row of the random number table and read 20 single digits between 1 and 5. He will record the number of digits that are a 1.
He can select a row of the random number table and read 100 single digits between 1 and 5. He will record the number of digits that are a 1.
He can select a row of the random number table and read 100 single digits between 1 and 5. He will record the percentage of the digits that are a 1.

Answer:

  y = 27

Step-by-step explanation:

The altitude of a right triangle creates two <em>triangles that are each similar to each other and to the larger right triangle</em>. This means corresponding sides are proportional.

If we write the proportion for the legs, we get ...

  (long leg) / (short leg) = y/18 = 18/12

Multiplying by 18 gives us ...

  y = 18(18/12)

  y = 27

_____

<em>Additional comment</em>

The leg/leg proportion above gave rise to the relation ...

  altitude² = (left hypotenuse segment)×(right hypotenuse segment)

That is, the altitude is the <em>geometric mean</em> of the two hypotenuse segments it touches. 18 = √(12y)

__

There are two other "geometric mean" relationships in this triangle.

  • The upper left side is the geometric mean of the left hypotenuse segment and the whole hypotenuse (the two segments it touches at the bottom).
  • The upper right side is the geometric mean of the right hypotenuse segment and the whole hypotenuse (the two segments it touches at the bottom).

Each of these relationships is ultimately derived from the fact that all of the triangles are similar. You really only need to remember that these triangles are all similar and corresponding sides of similar triangles are proportional. (In some cases, it can be a bit of a shortcut if you remember the geometric mean relations.)

Just want to double check our answer.
bearhunter [10]

0 divided by 2 is 0.

You can use the multiplicative identity property: the product of any number and zero is still zero.

Hope this helped :)
