16.4 is the answer. How to get the answer and others like it is like this. The first number after the decimal is the tenth place signaled by this .1 (For the examples I will always put the "1" where the value I'm trying to show) the hundredth place is here .21, and the thousandth is here .321 , hope this helps.
Part A:
For this case we have that the relationship between time and radius is linear.
We observe that for each day that passes, the radius increases two centimeters.
Therefore, the linear function is:
y = 2x
Since the linear function is exact, the correlation coefficient is:
r = 1
Answer:
r = 1
Part B:
As the linear function is:
y = 2x
So for days 1 and 2 the slope of the graph is:
m = 2
It means that the radius increases 2 centimeters per day.
Answer:
m = 2
Part C:
The data represents a correlation.
This is because the data follows a linear trend.
The radius always grows 2 centimeters for each day that passes.
Answer:
Correlation.
It depends on the value of t.
Answer:
A Median is the middle data value of an ordered data set, so, that leads me to believe your answer is 6.
Hope this helps!!
Have a nice day :)

Answer:
3+3i
Step-by-step explanation:
The mid point formula in a complex plane is for points a+bi and s+ti is

For points 1 + 9i and 5 — 3i


Midpoint = 3 + 3i
