Answer:

$\dfrac{3x^3+x-11}{x+1}=3x^2-3x+4-\dfrac{15}{x+1}$

Step-by-step explanation:

We want to determine the result of the quotient: $\dfrac{3x^3+x-11}{x+1}$

We follow the procedure of long division which is set out int he table below.

$\left|\begin{array}{c|c}&3x^2-3x+4\\-----&-----\\x+1&3x^3+x-11\\Subtract&-(3x^3+3x^2)\\&------\\&-3x^2+x-11\\Subtract&-3x^2-3x\\&------\\&4x-11\\Subtract&4x+4\\&------\\&-15\end{array}\right|$

Therefore:

$\dfrac{3x^3+x-11}{x+1}=3x^2-3x+4-\dfrac{15}{x+1}$

marin [14]

Answer:

D. Coefficient of Correlation

Step-by-step explanation:

The name itself "Coefficient of Correlation" involves the word correlation, meaning relationship between two things.

The coefficient of Correlation is used to determine how strong a relationship is between two variables.

The formula of Coefficient of Correlation gives a value between -1 and 1. Moreover, it helps to plot a graph showing the strength of relationship.

1 : A strong positive relationship

-1: A Strong negative relationship

0: No relationship at all

One of the most used formula is Pearson Correlation Coefficient Formula, picture of which is attached. X and Y represent two different set of datas.

The other terms are defined as :

Coefficient of Determination : Square of correlation between predicted scores and actual scores. It usually ranges from 0 to 1 .

Standard deviation of estimate : represents the amount of variation among a set of values .

Standard Error of estimate : It is the measure of dispersion of sample means around population means.
