FrozenT [24]

Answer:

Step-by-step explanation:

There are 9 city council members.

We have to choose 4 of them.

We have to use the combination as :

$^9C_4$

where, 9 is the population size

4 is the sample size.

Therefore, the total number of possible samples without replacement is given as :

$^9C_4=\frac{9!}{4!(9-4)!}$

$=\frac{9!}{5! \ 4!}$

$=\frac{9 \times 8 \times 7 \times 6}{4 \times 3 \times 2 \times 1}$

= 126

Which set of three numbers could represent the lengths of the sides of a right triangle?

Lubov Fominskaja [6]

Answer=5,12,13

Just plug all of these values into the pythagorean theorem. If they work, then they could represent a right triangle.

For example:
5²+12²=13²
25+144=169
169=169
