There are 13 students in a​ class: 8 are wearing all blue and 5 are wearing all green. The teacher assigns seats at random. How
Ulleksa [173]

Using the arrangements formula, the number of distinct seating arrangements is:

1287.

<h3>What is the arrangements formula?</h3>

The number of possible arrangements of n elements is given by the factorial of the number n, that is:

A_n = n!

When elements are divided and classified with repetition, the number of arrangements is given as follows:

A_n^{n_1, n_2, \cdots, n_n} = \frac{n!}{n_1!n_2! \cdots n_n}

In the context of this problem, the parameters are given as follows:

  • n = 13, as there are 13 students in the class.
  • n_1 = 8, as 8 of the students are wearing all blue.
  • n_2 = 5, as 5 of the students are wearing all red.

Hence the number of distinct seating arrangements is calculated as follows:

A_{13}^{8,5} = \frac{13!}{5!8!} = 1287

bagirrra123 [75]

Answer:

See below

Step-by-step explanation:

The three angles inside of the triangle sum to 180

11x + 4       + 3x      + 78 = 180

14x +82 =180

x = 7

then B =   11x + 4    = 11(7) + 4 = 81 degrees

C =  3x = 21 degrees
