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:
see the explanation
Step-by-step explanation:
we know that
In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant called the common difference
we have
Let
------>
------>
------>
------>
so
the common difference between consecutive terms is equal to 5
we can rewrite the formula as
-----> given formula
For n > 1
where
an is the term that you want to find (position n)
a(n-1) is the known term position (n-1)
Find a_8
For n=8
I need to know a_7
or
we know that
The general formula for arithmetic sequence is equal to
where
an is the term that you want to find (position n)
a_1 is the first term
d is the common difference
n is the number of terms
we have
substitute
so
For n=8
Answer:
Domain: [-3, 3]
Range: [-1, 5]
Step-by-step explanation:
Reminder: domain is the x values that will make the function defined, and range is the possible y values the function could get.
Keeping that in mind, you can see that the domain of this function is [-3, 3] (using interval notation) and the range is [-1, 5].
Or, you could express the domain as -3≤x≤3 and the range as -1≤y≤5.
I hope this helped.
Answer:
A
Step-by-step explanation:
The tangent- tangent angle DEF is half the difference of the measure of the intercepted arcs , that is
(y - 127) = 53 → A
