To solve the problem we must know about the correlation coefficients.
<h3>What is the
correlation coefficient?</h3>
The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
- 1 indicates a strong positive relationship.
- -1 indicates a strong negative relationship.
- A result of zero indicates no relationship at all, therefore, independent variable.
The correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".
Given to us
- The correlation coefficient for the data is −0. 9847.
As we can see that the value of the correlation coefficient is 0.9847, therefore, it is close to 1 means the relationship is strong, while the '-' symbol denotes that the relationship is negative.
Hence, the correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".

Answer:
Step-by-step explanation:
The value of a simple interest account is
A=P(1+rt), A=present amount, P=principle, r=rate, t=time
A=20000(1+0.02(8))
A=20000(1.16)
A=$23200.00
Answer: choice A) -6
-----------------------------------------------
Work Shown:
Plug in x = 1
f(x) = 17-x^2
f(1) = 17-1^2
f(1) = 17-1
f(1) = 16
Then plug in x = 5
f(x) = 17-x^2
f(5) = 17-5^2
f(5) = 17-25
f(5) = -8
So the average rate of change (AROC) from x = 1 to x = 5 is...
AROC = (f(b)-f(a))/(b-a)
AROC = (f(5)-f(1))/(5-1)
AROC = (-8-16)/(5-1)
AROC = (-24)/(4)
AROC = -6
That's why the answer is choice A) -6
