enot [183]

Answer:

$y = 415.113 -6.593 x_1 -4.504 x_2$

Step-by-step explanation:

Given

$x_1: 16.7\ 17.4\ 18.4\ 16.8\ 18.9\ 17.1\ 17.3\ 18.2\ 21.3\ 21.2\ 20.7\ 18.5$

$x_2: 30\ 42\ 47\ 47\ 43\ 41\ 48\ 44\ 43\ 50\ 56\ 60$

$y: 210\ 110\ 103\ 103\ 91\ 76\ 73\ 70\ 68\ 53\ 45\ 31$

Required

Use R code to determine the regression equation

$y = b_o + b_1x_1 + b_2x_2$

First, write the following code in a R program

$x1$

$x2$

$y$

$mod$ ~ $x1+x2)\\$

$summary(mod)$

Next, run the program

See attachment for program and output

From the output, go to coefficients:

Check Estimate Std. column, you have the following:

$(Intercept) = 415.113$

$x_1 = -6.593$

$x_2 = -4.504$

$y = b_o + b_1x_1 + b_2x_2$ implies that:

$b_o \to$ Intercept

$b_1 \to x_1$

$b_2 \to x_2$

Hence, the least square regression equation is:

$y = 415.113 -6.593 x_1 -4.504 x_2$

A rectangle has a width of 44 centimeters and a perimeter of 180 centimeters what is the rectangle length

Mumz [18]

If the width of a rectangle is 44 cm, multiply that by 2 for the other side and you have 88. 180 - 88 = 92, so divide that by 2 for each side and the length is 46 cm.

2 significant figures of 124.4562 L

Charra [1.4K]

Answer:

120 liters.

Step-by-step explanation:

124.4562 rounded to the nearest 2 significant figures is 120.

The third significant figure is 4, which is lower than five, so when rounded don't add +1 to the second significant figure.

The answer is 120 liters.

Expand . ( 3x –2 ) 2 please help me with this.

Ainat [17]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{9x}^2\textsf{ - 12x + 4}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{(3x - 2)}^2$

Find: $\textsf{Simplify the expression}$

Solution: It looks like 2 is at the end of the parenthesis where the power would be instead of distributing the number. If so the following steps would be followed.

<u>Expand</u>

$\textsf{(3x - 2)}^2$

$\textsf{(3x - 2)(3x - 2)}$

$\textsf{(3x * 3x) + (3x * (-2)) + (3x * (-2)) + (-2 * (-2))}$

<u>Simplify</u>

$\textsf{9x}^2\textsf{ - 6x - 6x + 4}$

$\textsf{9x}^2\textsf{ - 12x + 4}$

Therefore, after following the provided information we are able to determine that the expanded form would be 9x^2 - 12x + 4.
