What are the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2? x = (

Crank

The x =0 and y = 1 are coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2.

<h2>We have to determine</h2>

What are the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2?

<h3>According to the question</h3>

A line segment at points A(2, -3) and B (-4, 9).

The x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2 is given by;

$\rm x=\dfrac{m}{(m+n)} [x_2- x_1]+ x_1 \\
\\
 y=\dfrac{m}{(m+n)} [y_2- y_1]+ y_1 \\
\\$

Where $\rm x_1 = 2 , \ x_2 =-4, \ y_1 =-3, \ y_2 = 9$

Substitute all the values in the formula;

$\rm x=\dfrac{m}{(m+n)} [x_2- x_1]+ x_1 \\\\$

$\rm x=\dfrac{1}{(1+2)} [-4-(2)]+ (2)\\\\ x = \dfrac{1}{3} \times (-6) +2 \\
\\
x = -2+2\\
\\
x=0$

$\rm y=\dfrac{m}{(m+n)} [y_2- y_1]+ y_1 \\\\ y=\dfrac{1}{(1+2)} [9-(-3)]+ (-3)\\\\
y = \dfrac{1}{3} \times (12) -3\\
\\
y = 4-3\\
\\
y =1$

Hence, the x =0 and y = 1 are coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2.

In a hat, you have index cards with the numbers 1 through 10 written on them. Find how many of the 10 possible numbers you can p

AURORKA [14]

8,5.7,1,3,2,4,6 is the correct order

Step-by-step explanation:

1. There are 10 numbers from 1 to 10 , thus there are 10 possible outcomes.

Determine the number of favourable outcomes for each event:

Number greater than 0 : 10 favourable outcomes ( 1,2,3,4,5,6,7,8,9,10)

Even number : 5 favourable outcomes ( 2,4,6,8,10)

Number is at least 2 : 9 favourable outcomes ( 2,3,4,5,6,7,8,9,10)

Number is at most 0 : 0 favourable outcomes ( as none of the integers from 1 to 10 are at most 0 )

Number is divisible by 3 : 3 favourable outcomes ( 3, 6,9)

Number is divisible by 5 : 2 favourable outcomes ( 5, 10)

Prime number : 4 favourable outcomes ( 2, 3, 5, 7 )

Number less than the greatest prime number : 6 favourable outcomes ( 1, 2,3,4,5,6 as 7 is the greatest prime number from the numbers of 1 to 10 )

2. The more favourable outcomes correspond with an event, the more likely the event is to happen. Thus the number is at most 0 is the least likely and the number greater than 0 is the most likely.

Let us then number the events from least likely to most likely:

Number greater than 0: 8

Even number: 5

Number is at least 2: 7

Number is at most 0:1

Number is divisible by 3: 3

Number is divisible by 5: 2

Prime number 4

Number less than the greatest prime number: 6

So the order is 8,5.7,1,3,2,4,6
