Answer:
11) c = 16.1
12) c = 11.4
Step-by-step explanation:
11)
a² + b² = c²
8² + 14² = c²
64 + 196 = c²
c² = 260
c = 16.1
12)
a² + b² = c²
7² + 9² = c²
49 + 81 = c²
c² = 130
c = 11.4

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
