Answer:
a. 205320
b. 34220
c. 60! / (35)! (25)! + 60!/ (40)!(20)! + 60!/ (45)! (15)!
Step-by-step explanation:
a) The number of ways to dustribute exams among the TA's is:
n / (n - r)!
n= number of things to choose from
r= Choosing r number
60P3= 60! / (60 - 3)!
(60)(59)(58)(57)! / (57)!
=205320
B) The number of ways to dustribute the exams among the TA's is:
n! /(n - r)! r!
60C3= 60! /(60 - 3)! 3!
= 60!/ 57! 3!
= 60 × 59 × 58 / 3 × 2 × 1
= 34220
C) The required number of ways is:
60C25 + 60C20 + 60C15
= 60! / (35)! (25)! + 60!/ (40)!(20)! + 60!/ (45)! (15)!
The answer is 144 because you have to do this 4 ×(2+34).it is telling you that the x equals to 4 that’s why it is 34 not 3x.
Table b
explanation: there’s a pattern
Answer:
The answer is below!!
Step-by-step explanation:
The formula used to find the area of a circlular sector - a pie-shaped part of a circle. ... π. 4. 2. ·. 86. 360. = 12.01. What the formulae are doing is taking the area of the whole ... So for example, if thecentral angle was 90°, then the sector would have an area equal to one ... r is the radius of the circleof which the sector is part.
