klasskru [66]

Answer: $\frac{22}{3}$

Step-by-step explanation: Divide

$5\frac{1}{2}\div \frac{3}{4}$

Step 1: Convert the mixed number to improper fraction

$5 \frac{1}{2} =\frac{11}{2}$

$= \frac{11}{2}\div \frac{3}{4}$

Step 2: Reciprocal

$\frac{11}{2}\times \frac{4}{3}$

Step 3: Divide the common factors

$4 \div 2 = 2\\\\=\frac{11}{1}\times \frac{2}{3}$

Step 4: Multiply

$\frac{11\times \:2}{1\times \:3}\\\\=\frac{22}{3}$

Greeley [361]

Answer:

<h3>The Option B) Multiple regression is correct</h3><h3>Regression analysis involving one dependent variable and more than one independent variable is known as <u>multiple regression.</u></h3>

Step-by-step explanation:

Given that regression analysis involving one dependent variable and more than one independent variable

For : Regression analysis involving one dependent variable and more than one independent variable is known as <u>multiple regression</u>

In statistics, a linear regression is a linear relationship between a dependent variable and one or more independent variables.

In statistics for more than one independent variable and with one dependent variable in regression analysis , then the regression is called as multiple regression.

Therefore Option B) Multiple regression is correct

<h3>Regression analysis involving one dependent variable and more than one independent variable is known as <u>multiple regression</u>.</h3>
