Answer:

Explanation:

The associative property of multiplication basically groups two numbers together in parentheses without changing the answer to the equation, for example (6 * 3) * 6 = 108

That equations equals the same as 6 * 3 * 6 = 108

Answer:

clockwise
90°
origin

Step-by-step explanation:

The answer statement tells you the transformation is a rotation. The original is in the 2nd quadrant, and the image is in the 1st quadrant, representing a clockwise rotation. AB points east, while A'B' points south, a rotation of 90° (clockwise). Each image point is the same distance from the origin as its preimage point. The origin is the center of rotation.

∆ABC is transformed by a clockwise rotation 90 degrees with a center at the origin .

Select all expressions that are equivalent to 4x+2(2x-5)-(3-5x)

Arada [10]

For this case we have the following expression:

$4x + 2 (2x-5) - (3-5x)$

Applying distributive property to the terms within parentheses taking into account that:

$- * + = -\\- * - = +$

We have:

$4x + 4x-10-3 + 5x =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

$4x + 4x + 5x-10-3 =\\13x-13$

Thus, an equivalent expression is:

$13x-13$

Answer:

$13x-13$

. 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

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