Step-by-step explanation:
<u>Quadratic Equation Solving</u>
We have the equation:
Divide by 8:
Now complete the squares so the left side is a perfect square of a binomial:
Factoring the perfect square:
Taking the square root:
The square root of a negative number is an imaginary number:
Solving for x:
The solutions are:
Answer:
-10.
Step-by-step explanation:
x^0 = 1 so its -10 * 1
= -10.
When calculating correlation and regression both sets of data must be Statistical.
According to the statement
we have to find the type of data when we calculate the correlation and regression both sets.
so, The difference between these two statistical measurements is that correlation measures the degree of a relationship between two variables (x and y), whereas regression is how one variable affects another.
And when we calculate both then data sets must be a statistical data. because correlation summarizing direct relationship between two variables and regression predict or explain numeric response. So, without statistical data this is not possible to calculate correlation and regression both sets.
so, When calculating correlation and regression both sets of data must be Statistical.
