ANSWER: The statistical procedure that should be performed is REGRESSION.
Step-by-step explanation: Regression is a statistical procedure that is used to estimate the relationship between an independent variable and a dependent variable using their mean values.
The independent variable in this case is the hours each student spend in studying, while the dependent variable is the students grade.
Since the researcher wants to determine if the hours a student spend in studying maths and science has any significant effect on their grades. The researcher should use regression, because it will show if the two variables are related and how it relates, by showing how far the points are from the trend lines of the graph.
I think the area of 1 is 5 or 8
The Fundamental Theorem of Algebra states that any constant-coefficient single-variable polynomial of degree n has (counting multiplicity) n complex roots (Real numbers are a subset of Complex numbers).
_____
Especially for higher-degree polynomials, some roots may not be real. Certainly, if the polynomial has complex coefficients (having an imaginary part), at least one root will be complex (have an imaginary part). That is, the only way you can find the roots is to admit the existence of complex numbers. One simple example is ...
... x^2 +1 = 0
Answer:
14
Step-by-step explanation:
To find the unit rate, we want the denominator to be 1. So 168/12 is 14.
