Answer:

∠B = 89°

Step-by-step explanation:

  • supplementary angles are two angles whose sum is 180°

∠A + ∠B = 180°

x - 18 + x - 20 = 180

x + x = 180 + 18 + 20

2x = 218

x = 218/2

x = 109

∠B = 109 - 20 = 89

∠B = 89°

Then , the number of ways to choose a dancing committee if it is to consist of 4 freshmen, 5 sophomores, 2 juniors, and 3 seniors :-

Then , the number of ways to choose a dancing committee if it is to consist of 4 freshmen, 5 sophomores, 2 juniors, and 3 seniors :-

Then , the number of ways to choose a dancing committee if it is to consist of 4 freshmen, 5 sophomores, 2 juniors, and 3 seniors :-

^8C_4\times ^9C_5\times^9C_2\times^7C_3

=\dfrac{8!}{(8-4)!4!}\times\dfrac{9!}{(9-5)!5!}\times\dfrac{9!}{(9-2)!2!}\times\dfrac{7!}{3!(7-3)!}\\\\ =\dfrac{8\times7\times6\times5\times4!}{4!4!}\times\dfrac{9\times8\times7\times6\times5!}{4!5!}\times\dfrac{9\times8\times7!}{7!2!}\times\dfrac{7\times6\times5\times4!}{3!4!}\\\\=11113200

∴ The number of ways to choose a dancing committee if it is to consist of 4 freshmen, 5 sophomores, 2 juniors, and 3 seniors = 11113200

Answer:

1. Degree= 6, trinomial

2. degree= 4, binomial

Step-by-step explanation:

1. The largest exponent is 6 making it the degree and there are three terms because (m^5n^2), (mn^2), (n^6).

2. Since (9a^2bc^2) has the more than 1 exponent, you add them and the  degree is 4. There are two terms because (2a^3b), (9a^2bc^2).

How many license plates in Ontario were registered between the following licence plates? As the question is asking for plates be
Liono4ka [1.6K]

The number of plates is an illustration of permutation and combination

The number of plates is 2592

<h3>How to determine the number of plates</h3>

The range is given as: AVVJ 144 To: BVNP 199 (exclusive)

From the range, we have the following highlights:

  • The first letter can be either A or B (i.e. 2 letters)
  • The second letter can be only V (i.e. 1 letter)
  • The third letter can be from W to M (24 letters)
  • There are 54 numbers between 144 and 199

The number of plates (n) is then calculated as:

n = 2 * 1 * 24 * 54

Evaluate the product

n = 2592

Hence, the number of plates (n) is 2592
