Answer:

distance = independant; time = dependant

Step-by-step explanation:

You are able to change the distance you travel, making it the independant. As you go farther, the time increases, so it is dependant on the distance traveled, therefore it is the dependant.

The total distance traveled by a car depends on the amount of time. For instance, a car has been driving 50 miles per hour. Therefore, the distance covered is the dependent variable and time is the independent variable.

Statistics Question. Use the Desmos graphing calculator to find the least-squares regression line for the dataset in the table:

Soloha48 [4]

Given:

The table of values.

To find:

The least-squares regression line for the data set in the table by using the desmos graphing calculator.

Solution:

The general form of least-squares regression line is:

$\hat{y}=mx+b$ ...(i)

Where, m is the slope and b is the y-intercept.

By using the desmos graphing calculator, we get

$m\approx 2.55,b\approx -6.435$

Substitute these values in (i).

$\hat{y}=(2.55)x+(-6.435)$

$\hat{y}=2.55x-6.435$

Therefore, the correct option is A.

Answer and Step-by-step explanation:

The answer is the second answer choice. y = 2x + 1

By looking at the graph, we see that there is a y-intercept at (0, 1), and it has a positive slope of 2.

Hi,

$f(x)=x+7\\

g(x)= \dfrac{1}{x-13} \\

(fog)(x)=f(g(x))=f(\dfrac{1}{x-13})=\dfrac{1}{x-13}+7\\


$
Domain of (fog)(x) is R \ {13} =(-oo 13[ U ]13 +oo)

If prism A and Prism B have a ratio of similarity of 2:3, what is the volume of prism A if Prism B's volume is 56 cubic inches

Sunny_sXe [5.5K]

Answer:

16.6 in³

Step-by-step explanation:

Given the ratio of similarity = 2 : 3, then

the ratio of volumes = 2³ : 3³ = 8 : 27

let the volume of prism A be x then by proportion

$\frac{x}{8}$ = $\frac{56}{27}$ ( cross- multiply )

27x = 448 ( divide both sides by 27 )

x = 448 ÷ 27 ≈ 16.6 ( to 1 dec. place )

Prism A has a volume of approx 16.6 in³
