Using the probability concept, it is found that there is a \frac{2}{5} probability the student is a boy.

<h3>What is a probability?</h3>
  • A <em>probability </em>is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, according to the two-way table found on the internet when we research the problem:

  • There are 11 people who are 12, of which 4 are girls and 7 are boys.
  • Hence, in total, there are 21 people, of which 13 are girls and 8 are boys.
  • Then, we find that there are 10 people aged 11, of which 6 are girls and 4 are boys.

Then:

p = \frac{4}{10} = \frac{2}{5}

There is a \frac{2}{5} probability the student is a boy.

Answer:

\displaystyle 36\:units

Step-by-step explanation:

Split up this Isosceles, Right Triangle into two congruent smaller right triangles. The reflexive side [the line that splits them apart] is 6 units, and both legs are 8 units, leaving the hypotenuses to AUTOMATICALLY be 10 units, according to the Pythagorean Theorem:

\displaystyle a^2 + b^2 = c^2 \\ \\ 6^2 + 8^2 = 10^2 \\ \\ 36 + 64 = 100 \\ \\ 100 = 100

With this Pythagorean Triple, we know that our dimensions are correct. Now, to find the perimeter, just add up all the sides EXCEPT for the divider:

\displaystyle 2[10] + 2[8] = 20 + 16 = 36
