Answer:
it is 4.17
Step-by-step explanation:
i just know
The cost price of each pair of socks is 3 dollars and 97 cents
The total money paid by Jessica for 4 pair of socks = $20
The money that the cashier returned = $4.12
It is also given that, each pair of sock would cost same price
We need to find, The cost price of each pair of socks
To do that, first let's find
The amount that was paid for 4 pair of socks = 20 - 4.12 = $15.88
Now,
The cost price of one pair of sock = 
= $3.97
= 3 dollars and 97 cents

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.
