Answer:
x = 9
Step-by-step explanation:
Given
5x - 31 = 23 - x ( add x to both sides )
6x - 31 = 23 ( add 31 to both sides )
6x = 54 ( divide both sides by 6 )
x = 9
Answer:
The set of all real values except 7
Step-by-step explanation:
We are given that,
Domain of the function f(x) is 'the set of all real values except 7'.
Domain of the function g(x) is 'the set of all real values except -3'.
It is required to find the domain of 
.
Now, we know that,
<em>The composition of functions 
and 
will be defined where the function is defined.</em>
Since, the domain of f(x) is 'the set of all real values except 7'.
Thus, the domain of is also 'the set of all real values except 7'.
Using a calculator, inserting the values of x and y, the correlation coefficient for the given data-set is of -0.9422.
<h3>How to find the correlation coefficient of a data-set?</h3>
Using a calculator, the correlation coefficient is found inserting the ordered pairs (x,y) in the calculator.
In this problem, we have that:
- The values of x are: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5.
- The values of y are: 112.5, 110.875, 106.8, 100.275, 91.3, 79.875, 70.083, 59.83, 30.65, 0.
Hence, using a calculator, the correlation coefficient is of -0.9422.
