Answer:
2.0
Step-by-step explanation:
Couldn't really understnd what you wrote but I'll assume it's the standard deviation of a fair, 7-sided die
The standard deviation is just the square root of the variance (which is just the second moment minus the first moment squared)
The first moment (AKA the average is..)
The second moment is..
Answer:
(a) Bacterial 1 had a faster rate of growth.
(b) The population of f(x) always exceed the population of g(x). In other words, population of g(x) cannot exceed the population of f(x).
Step-by-step explanation:
Consider the given functions are
where, x is the time (in hours) and f(x) and g(x) are the number of bacteria (in thousands).
(a)
The rate of change of a function f(x) on [a,b] is
Rate of change between third and sixth hour of first function is
Rate of change between third and sixth hour of second function is
Since , therefore bacterial 1 had a faster rate of growth.
(b)
The initial population of f(x) is 7 and it increases exponentially.
The initial population of g(x) is 0 and it increases linearly.
It means population of f(x) always exceed the population of g(x).
In other words, population of g(x) cannot exceed the population of f(x).
