Answer:
so the probability of selected student is in the drama club is 1/5
Step-by-step explanation:
total students = 40
drama club= 8
art club= 12
we have to find probability of drama club
P (drama) = favorable outcome / total outcome
= 8 / 40
= 1/ 5
so the probability of selected student is in the drama club is 1/5
By using <em>algebra</em> properties and <em>trigonometric</em> formulas we find that the <em>trigonometric</em> expression

<h3>How to prove a trigonometric equivalence by algebraic and trigonometric procedures</h3>
In this question we have <em>trigonometric</em> expression whose equivalence to another expression has to be proved by using <em>algebra</em> properties and <em>trigonometric</em> formulas, including the <em>fundamental trigonometric</em> formula, that is, cos² x + sin² x = 1. Now we present in detail all steps to prove the equivalence:
Given.
Subtraction between fractions with different denominator / (- 1) · a = - a.
Definitions of addition and subtraction / Fundamental trigonometric formula (cos² x + sin² x = 1)
Definition of tangent / Result
By using <em>algebra</em> properties and <em>trigonometric</em> formulas we conclude that the <em>trigonometric</em> expression
is equal to the <em>trigonometric</em> expression
. Hence, the former expression is equivalent to the latter one.

What kind of question is this? and where is the data
Answer:
11 33/35
Step-by-step explanation:
5 3/7 = 5 × 7/7 + 3/7 = 35 + 37 = 38/7
38/7 ÷ 5/11 = 38/7 × 11/5 = 38 × 11/7 × 5 = 418/35
418/35 = 11 33/35
Hope this helps!
