Answer:

3240°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 20, hence

sum = 180° × 18 = 3240°

108 / 1376 is the probability that a student participates in both sports and music.

<u>Step-by-step explanation:</u>

It is given that,

A suburban high school has a population of 1376 students.

  • Let the event A be the no.of students participated in sports.
  • Let the event B be the no.of students participated in music.

The number of students who participate in sports is 649.

The number of students who participate in music is 433.

<u>To find the probability of event A (sports) :</u>

P(sports) = No.of students participated in sports / Total students.

⇒ 649 / 1376

∴ P(A) = 649 / 1376

<u>To find the probability of event B (music) :</u>

P(music) = No.of students participated in music / Total students.

⇒ 433 / 1376

∴ P(B) = 443 / 1376

From the question, we know that the probability that a student participates in either sports or music is 974 /1376.

∴ P(A∪B) = 974 / 1376

<u>To find the probability that a student participates in both sports and music :</u>

The formula used here is,

P(A∩B) = P(A) + P(B) - P(A∪B)

⇒ 649 / 1376 + 433 / 1376 - 974 /1376

⇒ 108 / 1376

∴ P(A∩B) = 108 / 1376

andrew-mc [135]

Answer:

There are 192 window panes in total.

Step-by-step explanation:

Since each window has four window panes across and four window panes down,the number of panes per window is:

w=4*4=4^2

The total number of window panes in 'n' windows is:

P=n*4^2

With n = 12 windows, the expression that describes the total number of window panes is:

P=12*4^2\\P=192\ panes

There are 192 window panes in total.
