Answer:
Option A - The number of visitors is multiplied by (1+r) each year
Step-by-step explanation:
Given : The number of visitors to an art museum increases each year. The function V(t)=N(1+r)^t represents the number of visitors to the museum at year t, where N is the number of visitors in year 0 and r is the rate of increase.
To find : Select the correct statement?
Solution :
We have given an exponential function,
The function V(t)=N(1+r)^t represents the number of visitors to the museum at year t, where N is the number of visitors in year 0 and r is the rate of increase.
As In year 0,
The initial visitors is V(t)=N(1+r)^0=N
In year 1,
V(t)=N(1+r)^1=N(1+r)
In year 2,
V(t)=N(1+r)^2
So, According to this the number of visors is multiplied by (1+r) each year.
Therefore, Option A is correct.
Answer: M =
Step-by-step explanation:
M (x + y) + 4y = x + 2y (Multiply in both sides)
M (x + y) = x + 2y - 4y
M (x + y) = x - 2y (Divide (x+y) from both sides)
M =
B. polygons are figures with 3 sides or more
You can't simply consider the mean of the three means, because each mean is achieved by a different number of students.
Consider an extreme example, just to understand the concept: if 1 students gets a grade of 100 and one million students get a grade of 0, we can't say that the combined mean is 50!
What we need to do is called a weighted average, i.e. an average where we consider the weight of every entry - in this case the weight is given by how many students achieved a certain grade.
So, if each value comes with a weight , the weighted average is computed as
Applying this formula to your case, we have
