Rewrite using a single exponent.<br> 53.53

Helga [31]

Answer:

${5}^{6} \: \: or \: \: {25}^{3} = 15625$

Step-by-step explanation:

${5}^{3} \times {5}^{3}$

Here we can solve this in 2 ways ,

Method 1 :

${5}^{3} \times {5}^{3}$

Here the bases are equal. So,

$= > {5}^{3 + 3} = {5}^{6} = 15625$

Method 2 :

${5}^{3} \times {5}^{3}$

Here the exponents are same. So,

$= > {(5 \times 5)}^{3} = {25}^{3} = 15625$

. The estimate regression equation for a model involving two independent variables and 10 observations follows.y = 29.1270 + 0.5

beks73 [17]

Answer:

b) y = 289.815 when $x_1 = 180 \text{ and } x_2 = 310$

Step-by-step explanation:

We are given the following information in the question:

$y = 29.1270 + 0.5906x_1 + 0.4980x_2$

where y is the dependent variable,

$x_1, x_2$ are the independent variable.

The multiple regression equation is of the form:

$y = b_0 + b_1x_1 + b_2x_2$

where,

$b_0$ : is the intercept of the equation and is the value of dependent variable when all the independent variable are zero.

$b_1$ : It is the slope coefficient of the independent variable $x_1$ .

$b_2$ : It is the slope coefficient of the independent variable $x_2$ .

The regression coefficient in multiple regression is the slope of the linear relationship between the dependent and the part of a predictor variable that is independent of all other predictor variables.

Comparing the equations, we get:

$b_1 = 0.5906\\b_2 = 0.4980$

This means holding $x_2$ constant, a change of one in $x_1$ is associated with a change of 0.5906 in the dependent variable.

This means holding $x_1$ constant, a change of 1 in $x_2$ is associated with a change of 0.4980 in the dependent variable.

b) We have to estimate the value of y

$y = 29.1270 + 0.5906(180) + 0.4980(310) = 289.815$
