Answer:
In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others.
The order of operations is PEMDAS (parenthesis, exponents, multiplication/division, addition/subtraction). This means that you do multiplication before adding, so 3 + 4*6 is the same thing as 3 + (4*6). Because of this, Omar did not need to use a grouping symbol.
Answer:
(a) 21
(b)2520
Step-by-step explanation:
(a)
Using combination formula, nCr where n is the total sample and r is the limitation hence 7 combination 5.
[tex}7C5=\frac {7*6*5*4*3}{5*4*3*2*1}=\frac {2520}{120}=21[/tex]
(b)
If the scholarships are not equal
The number of ways to select the 5 students from 7 we use permutation formula hence
7P5 = 7*6*5*4*3 = 2520
