Answer:
-3072
Step-by-step explanation:
You can use sigma notation to represent an infinite series. For example, ∞∑n=110(12)n−1 is an infinite series. The infinity symbol that placed above the sigma notation indicates that the series is infinite. To find the sum of the above infinite geometric series, first check if the sum exists by using the value of r .
35 if whole number
34.7 to 1 dp
34.72 to 2dp
Answer: Yes
Step-by-step explanation:
Given that:
Number of employees (n) = 6
Number of employees who can work at a time (r) = 3
To know of its possible for different groups of employees to work for two wweka, then, the number of different groups or combination must be greater Than or equal to 14 (two weeks) ; Assume (1 week = 14 days)
Using the combination formula :
nCr = n! ÷ (n - r)!r!
6C3 = 6! ÷ (6 - 3)!3!
6C3 = 6! ÷ 3!3!
6C3 = (6*5*4) ÷ (3*2*1)
6C3 = 120 / 6
6C3 = 20 ways
Hence, 20 different groups of 3 employees can be made from all 6 employees. Hence, it is possible to have different groups work for two weeks
