The number property that will justify the step in the following expression. 2(5 • 17) = (2 • 5) 17 = 10 • 17 = 170 is; Associative Property

<h3>What is the Number Property that was used?</h3>

The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.

Now, this associative property is used here because we see that;

2(5 • 17) = (2 • 5) 17

In both left and right hand sides we see that despite the change in order, the result remains the same.

Aliun [14]
(141 + 162 + S) / 3 = 160

(303 + S) / 3 = 160

101 + S/3 = 160
-101 -101
S/3 = 59
*3 *3

S= 177

Jacques needs at least a 177 to get a 160 average

The estimate regression equation for a model involving two independent variables and 10 observations follows.
True [87]

Answer:

a) b_1 = 0.5906\\b_2 = 0.4980

b) y = 289.815

Step-by-step explanation:

We are given the following information:

The estimate regression equation for a model involving two independent variables and 10 observations follows:

y = 29.1270 + 0.5906x_1 + 0.4980x_2

where x_1, x_2 are the two independent variable and y is the dependent variable.

a) The regression line is of the form:

y = b_0 + b_1x_1 + b_2x_2\\\text{where } b_0 \text{ is the y-intercept and }b_1, b_2\text{ are the coefficients of} x_1, x_2\text{ respectively}

Comparing, we get,

b_1 = 0.5906\\b_2 = 0.4980

These are the coefficients of x_1, x_2 respectively, and helps us to know the the significance of the independent variable in predicting the independent variable.

b) We have to estimate y when

x_1 = 180 \text{ and } x_2 = 310\\y = 29.1270 + 0.5906x_1 + 0.4980x_2\\\text{Putting values}\\y = 29.1270 + 0.5906(180) + 0.4980(320)\\y = 289.815
