If the point P(x, y) partitions the segment AB in the ratio 1 : 1, then the point P is midpoint of segment AB.

The formula of a midpoint of segment:

$A(x_A;\ y_A),\ B(x_B,\ y_B)\\\\P_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)$

We have:

$A(13,\ 1)\to x_A=13,\ y_A=1\\B(-5,\ -3)\to x_B=-5,\ y_B-3\\\\P\left(\dfrac{13+(-5)}{2};\ \dfrac{1+(-3)}{2}\right)\to P\left(\dfrac{8}{2};\ \dfrac{-2}{2}\right)\to P(4,\ -1)$

Answer: C. (4, -1)

A company that relies on Internet-based advertising linked to key age demographics wants to understand the relationship between

MA_775_DIABLO [31]

Answer:

a)D. Since the company wants to predict revenue from advertising expenditure, the explanatory variable is advertising expenditure.

b)B. Since the company wants to predict revenue from advertising expenditure, the response variable is revenue

c)C. Since advertising expenditure is the explanatory variable, it should be plotted on the x-axis.

Step-by-step explanation:

a) The explanatory variable is the independent variable (the difference between explanatory an indepent is that independent means that it doesn´t depend of any variable at all and in the explanatory variable we are not 100% sure)

In this case, the company wants to know if the money they spend in advertising is related to the company's revenue. So , in this case the explanatory variablle is the money they spend in advetirsing while the dependent variable is the revenue ( that will increase or decrease depending on the money spent)

b) The response variable ist he dependent variable so like it was explained in a) is revenue.

c) In a cartesian graphic on the x axis we always draw the independent variable, so in this case we will draw the money spent in advertising.

What is the area of the composite figure? 262 cm2 264 cm2 266 cm2 268 cm2

miv72 [106K]

The Area is a two-dimensional scalar quantity. The area of the composite figure is 264 cm².

The area of a two-dimensional region, form, or planar lamina in the plane is the quantity that represents its extent. On the two-dimensional surface of a three-dimensional object, the surface area is its counterpart.

The composite figure can be broken down into four parts a square(A), a triangle(B) and two rectangles(C and D).

Now, if the area of the composite figure is taken out it will be,

$\text{Area of composite}=\text{Area of Square A} + \text{Area of triangle B} + \text{Area of Rectangle C} + \text{Area of Rectangle D}\\$

$\text{Area of Composte}=(10^2)+(\dfrac12 \times 6 \times 4)+(8 \times 4)+(20 \times 6)\\\\\text{Area of Composte}= 100+ 12 + 32 + 120 =264\rm\ cm^2$

Thus, the area of the composite figure is 264 cm².
