The explicit formula of the function d(n) is 
<h3>How to determine the explicit formula?</h3>
The function is given as:
d(1) = 2.7
d(n) = d(n-1) x (6.1)
The above means that the function is an exponential function, and it has the following parameters:
First term, d(1) = 2.7
Common ratio, r = 6.1
The explicit formula of an exponential function is:
So, we have
Hence, the explicit formula of d(n) is

One of your answers for sure can be D as it is a world wide company assembly.
I think the answer would be be C.
Answer: A,B, and D
Step-by-step explanation:
Answer:
Mean = 30.68
Standard deviation = 6.095
Two standard deviations above the mean = 42.87
Step-by-step explanation:
Given the following data :
21; 21; 22; 23; 24; 24; 25; 25; 28; 29; 29; 31; 32; 33; 33; 34; 35; 36; 36; 36; 36; 38; 38; 38; 40
Mean = Σ(x) / n
n = 25
Σ (X) = 767
Mean (m) = 767 / 25
Mean (m) = 30.68
Standard deviation : sqrt[Σ(x - m) / n]
Using a calculator :
Standard deviation = 6.095 ( 2 decimal places)
2 standard deviations above the mean :
Mean + 2(standard deviation)
Mean + 2(6.095)
30.68 + 12.19
30.68 + 12.19
= 42.87
