Answer:

So the coordinates of M are (8.5,2.17)

Step-by-step explanation:

To obtain a 3:5 ratio, the x coordinate of M is 3/5 of the way between the x-coordinate of X (1) and the x-coordinate of Y (10).

3/5 of that distance = 3/5 * (10 - 1) = 7.5, which you add to the x-coordinate of X(1), to get the x-coordinate of M (8.5).

Similarly, the y-coordinate of M is 3/5 of the way between the y-coordinate of X (-2) and the y-coordinate of y (3). 5/6 of that distance = 3/5* (3 - - 2) = 4.17, which you add to the y-coordinate of X(-2), to get the y-coordinate of M(2.17).

So the coordinates of M are (8.5,2.17)

Solve by elimination method : x - y = 2 , x + y = 12.
aalyn [17]
Answer: (7,5) X=7 and Y=5

Explanation:

Add the two equations together to eliminate y from the system.

x-y=2 + x+y=12
= 2x = 14

Divide both sides by 2

x=7

Substitute the value found for x into one of the original equations to solve for y

(7)-y=2

Move all terms to one side to make it easier

-y=2-7

Subtract

y=5

Answer:

This would be test of independence because it contain only one sample test

Step-by-step explanation:

Test of independence determine two factors are independent or not

For example

if we do a test of independence  

null hypothesis : H 0: Being a cell phone user while driving and receiving a speeding violation are independent events. If the null hypothesis were true, we would expect about 28 people to use cell phones while driving and to receive a speeding violation.

Therefore in the given question Each respondent answer that it might be in "Right Direction " or "Wrong Direction".

So it is a independent test.

<h3>Answer:  10</h3>

============================================

Work Shown:

First add up all the ages

9+13+9+10+10+9+10+10+11+9 = 100

Then divide that sum by 10, since there are 10 values we added up

100/10 = 10

The average age is 10 years old.
