Answer:

C. 8 inches wide and 15 inches long

Step-by-step explanation:

20 x 10 equals 200, so that means the only option that also equals 200 when multiplied togethor is C.

Area of the rectangle which was drawn by Lanu

=l*B

=10*20

=200

So if we multiply 8 and 25 then it equals to 200.

So the right answer of your question is of option B.

hope it will help you....

Good luck on your assignment

PLEASE HELP!! Convert each linear equation to standard form. y-4= -2(x+3)

So first, this is point slope form. The first step is to distribute.)
$y-4=-2x-6$
Then add 4 to both sides.
$y=-2x-2$
Then add 2x and it becomes
$2x+y=-2$

Use the figure below to find the value of x and PQ.

Scilla [17]

Answer:

x=14

PQ=46

Step-by-step explanation:

PT and TQ are equal, so we can set up the equation like this: PT=TQ

23=2x-5

calculate to find x

x=14

PQ is just PT+TQ so 23+23=46

. 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:

$b_1 = 0.5906\\b_2 = 0.4980$
