Answer:

A rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. ... However, numbers like √2 are irrational because it is impossible to express √2 as a ratio of two integers.

The perfect squares are the squares of the whole numbers: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 … Here are the square roots of all the perfect squares from 1 to 100. 1.

A waste management survey collected data about the types of materials that were recycled by three different states in

Lelechka [254]

As a percentage, the relative frequency of plastics recycling in New Mexico in 2008 compared to plastics recycled in all three states combined is approximately <u>11%</u>.

<h3>What is relative frequency?</h3>

A relative frequency measures the proportion of events that occur within a class out of the total number of observations.

When using relative frequency, the results are usually displayed in percentages, proportions, and fractions.

<h3>Data and Calculations:</h3>

Year State Recycled Plastics Relative

(thousands of tons) Frequency

2008 New Mexico 500 0.111 (500/4,500)

2008 New York 1,500 0.333 (1,500/4,500)

2008 Texas 2,500 0.566 (2,500/4,500)

Total 4,500 1

Thus, the relative frequency of plastics recycling in New Mexico in 2008 compared to plastics recycled in all three states combined is approximately <u>11%</u>.

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

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