The independent variable of a data set is w, while the dependent variable is x. Which of these is a response variable?

andrew-mc [135]

Well X in this is the response variable because it depends on the input of the w.

Factor −14 out of −12x−54y.

uysha [10]

we are given

$-12x-54y$

Since, we have to factor out -14

So, we will make both terms multiple of -14

so, we will multiply top and bottom of each terms by -14

$-12x-54y=\frac{-14}{-14}\times -12x-\frac{-14}{-14}\times 54y$

we can also write as

$-12x-54y=-14\times \frac{-12x}{-14}-(-14)\times \frac{54y}{-14}$

now, we can factor out -14

$-12x-54y=-14\times (\frac{-12x}{-14}-\frac{54y}{-14})$

now, we can simplify it

$-12x-54y=-14\times (\frac{6x}{7}+\frac{27y}{7})$ ..............Answer

The length and width of a rectangular room are measured to be 3.955±0.005m. Calculate the area of the room and its uncertainty i

Margarita [4]

Answer:

The area of the room and its uncertainty in square meters is:

15.642±0.040 $m^2$

Step-by-step explanation:

We know the area of a rectangular room is the multiplication of the length and width:

$Area= 3.955m*3.955m\\Area= 15.642 m^2$

Now we need to know the uncertainty, the uncertainty of a multiplication is:

$\frac{δ_a}{|Area|} =\frac{δ_L}{|L|}+\frac{δ_W}{|W|}$ (1)

$δ_A$ : Area uncertainty

$δ_L$ : Length uncertainty

$δ_W$ : Width uncertainty

A: Area of the room

L: Length

W: Width

Clearing the uncertainty of the area:

$δ_A=(\frac{δ_x}{|x|}+\frac{δ_y}{|y|})*Area$ (2)

$δ_A=(\frac{0.005}{|3.955|}+\frac{0.005}{|3.955|})*15.642 m^2$

$δ_A= 0.040 m^2$

The area of the room and its uncertainty in square meters is:

15.642±0.040 $m^2$
