A) 1.44
C) 3
The median is wrong because the median is the middle number
5 would be the dependent variable because the number 5 depends on how many greeting cards are bought.
Answer:
Exponential decay function; -0.94%
Step-by-step explanation:
We are given an exponential function and we are supposed to find whether the given function increases or decreases and also the percentage of increase or decrease.
Th given function is f(x) = 2060
Here x denotes the number of years.
At the start the value was 2060. In the next year it was multiplied by 0.9906.
This means that the value becomes 0.9906 times after each year.
Hence the value decreases by 0.0094 times its original value.
Converting to percentage it becomes 0.94% decrease after each year.
Yes it is. If you see any zero after the last number after a decimal point and then compare the same numbers but without the zero they are equivalent.
