dsp73

Answer:

The correct option is commutative property.

Step-by-step explanation:

The expression that Renee is simplifying is:

$(7)\cdot(\frac{13}{29})\cdot(\frac{1}{7})$

It is provided that, Renee recognizes that 7 and $\frac{1}{7}$ are reciprocals, so she would like to find their product before she multiplies by $\frac{13}{29}$ .

The associative property of multiplication states that:

$a\times b\times c=(a\times b)\times c=a\times (b\times c)$

The commutative property of multiplication states that:

$a\times b\times c=a\times c\times b=c\times a\times b$

The distributive property of multiplication states that:

$a\cdot (b+c)=a\cdot b+a\cdot c$

The identity property of multiplication states that:

$a\times 1=a\\b\times 1=b$

So, Renee should use the commutative property of multiplication to find the product of 7 and $\frac{1}{7}$ ,

$(7)\cdot(\frac{13}{29})\cdot(\frac{1}{7})=(7\times\frac{1}{7})\times\frac{13}{29}=\frac{13}{29}$

Thus, the correct option is commutative property.

larisa [96]

Answer:

The given statement is true.

Step-by-step explanation:

Regression Analysis:

Regression analysis is a technique that help us to find or define a relationship between a dependent and an independent variable.
It helps us to predict the dependent variables with the help of independent variables.
Various techniques are used for the prediction of independent variable.
It is a type of predictive statistical technique and helps us to find whether there is a significant relationship between the dependent and the independent variable.

Correlation analysis:

Correlation is a technique that help us to find or define a relationship between two variables.
It is a measure of linear relationship between two quantities.

It is not necessary that the that out of the two variable one needs to be dependent and the other to be independent.
Correlation can be positive, negative or zero correlation.

Thus, the given statement is true.
