Answer: 2 ^56 times more unique user ID's can be represented in the system.
Explanation:
5 bits will produce a maximum data allocation for User ID entries of 2^ 10.
12 bits will produce a maximum data allocation for User ID entries of 2^ 66.
Therefore the number of times more unique user ID's will be represented is 2^(66-10) = 2 ^ 56 times.
let's say they catch-up to each other after t hour.
so
in t hour distance travelled by Renee
d = speed × time = 50t
in t hour distance travelled by Kim
d = speed × time = 60(t-1) + 0×1 = 60(t-1)
Note: here kim didn't covered any distance in first hour and in rest t-1 hour it travelled all distance
now.as distance travelled by both is same so
60(t-1) = 50t
60t -60 = 50t
adding 60 both sides
60t = 50t+60
subtracting 50t both sides
60t -50t = 50t+60 - 50t
10t = 60
dividing by 10 both sides
t = 60/10 = 6
so in 6 hour both will catch-up to each other
Answer:
a parameter is fixed over time, while an exogenous variable is allowed to change over time.
Explanation:
A parameter can be defined as a value that can be passed to a function. Thus, a parameter refers to a value that must be passed into a function, subroutine or procedure when it is called.
This value can be passed to a function either by reference or by value.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
A variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited. Thus, a variable stores information which is passed from the location of the method call directly to the method that is called by the program.
An exogenous variable can be defined as a that's independent of other variables in a system i.e it's not affected by other variables.
This ultimately implies that, the difference between a parameter and an exogenous variable is that a parameter is fixed over time, while an exogenous variable is allowed to change over time and as such it has a relationship with other variables in a system.
