The answer is 10 because divide 20 and 2 and you get 10

Will i hate theese types of questions, so just guess.

Maybe 3 so 20 divided by 3= 6.66666667 (not 3)
Maybe 5 so 20 divided by 5 = 4 (works, but u must always try the other numbers to see)
Maybe 10 so 20 divided by 10= 2 (Perfect!)

So your answer is 2 rectangular prisms!

Hope my answer helped :D

2. Given a directed line segment with endpoints A(3, 2) and B(6, 11), what is the point that

KATRIN_1 [288]

Answer:

The point of division is (5 , 8)

Step-by-step explanation:

* Lets explain how to solve the problem

- If point (x , y) divides the line whose endpoints are $(x_{1},y_{1})$

and $(x_{2},y_{2})$ at ratio $m_{1}:m_{2}$ , then

$x=\frac{x_{1}m_{2}+x_{2}m_{1}}{m_{1}+m_{2}}$ and

$y=\frac{y_{1}m_{2}+y_{2}m_{1}}{m_{1}+m_{2}}$

* Lets solve the problem

- The directed line segment with endpoints A (3 , 2) and B (6 , 11)

- There is a point divides AB two-thirds from A to B

∵ The coordinates of the endpoints of the directed line segments

are A = (3 , 2) and B = (6 , 11)

∴ $(x_{1},y_{1})$ is (3 , 2)

∴ $(x_{2},y_{2})$ is (6 , 11)

∵ Point (x , y) divides AB two-thirds from A to B

- That means the distance from A to the point (x , y) is 2/3 from

the distance of the line AB, and the distance from the point (x , y)

to point B is 1/3 from the distance of the line AB

∴ $m_{1}:m_{2}$ = 2 : 1

∵ $x=\frac{(3)(1)+(6)(2)}{2+1}=\frac{3+12}{3}=\frac{15}{3}=5$

∴ The x-coordinate of the point of division is 5

∵ $y=\frac{(2)(1)+(11)(2)}{2+1}=\frac{2+22}{3}=\frac{24}{3}=8$

∴ The y-coordinate of the point of division is 8

∴ The point of division is (5 , 8)

107,600 115,220 104,910 median, mode, mean

san4es73 [151]

Answer:

1. Mean = 342.7 (Rounding to the nearest tenth)

2. Median = 167.5

3. Mode = There isn't a mode for this set of numbers because there isn't a data value that occur more than once.

Step-by-step explanation:

Given this set of numbers: 107, 600, 115, 220, 104, 910, find out these measures of central tendency:

1. Mean = 107 + 600 + 115 + 220 + 104 + 910/6 = 342.7 (Rounding to the nearest tenth)

2. Median. In this case, we calculate it as the average between the third and the fourth element, this way:

115 + 220 =335

335/2 = 167.5

3. Mode = There isn't a mode for this set of numbers because there isn't a data value that occur more than once. All the data values occur only once.
