Answer:
Hello! answer: 2
Step-by-step explanation:
Hello the mean is just all the numbers added up in a data set divided by the amount of numbers in the data set to get the average! So... 2 + 1 + 3 + 2 = 8 theres 4 numbers so we would divide by 4 so... 8 ÷ 4 = 2 therefore the mean is 2 HOPE THAT HELPS!
First of all, to find the ratio of male to female players you need to add the 5 and the 3 to get 8
You then need to divide 240 by 8 to get 30
You then multiply 30 by 3 to get 90 and 30 by 5 to get 150 respectively
The number of male players is 90 and female players is 150
You then do 150-90 which is 60
There is 60 females without male partners
Answer:
The area of the triangle is 16 unit²
Step-by-step explanation:
Area of a triangle given coordinates
D = (-1, -2)
E = (-5, 2)
F = (2, 2)
We note that the formula for finding the are triangle given the coordinates if presented as follows;
A = (x₁·y₂ + x₂·y₃ + x₃·y₁ - x₁·y₃ - x₂·y₁ - x₃·y₂)/2
Where:
D = (x₁, y₁)
F = (x₂, y₂)
E = (x₃, y₃)
Therefore;
x₁ = -1, y₁ = -2, x₂ = 2, y₂ = 2, x₃ = -5, y₃ = 2
Which gives;
A = ((-1)*(-2) + 2*2 + (-5)*(-2) - (-1)*2 - 2*(-2) - (-5)*2)/2
A = ((-1)·(-2) + 2·2 + (-5)·(-2) - (-1)·2 - 2·(-2) - (-5)·2)/2 = 16
The area of the triangle = 16 unit².
To maintain the same form, ergo, the same relative position between points A, B, C, and D, each of them have to be modified the same way, so speaking in coordinates, the following cannot happen:
A'-A ≠ B'-B ≠ C'-C<span> ≠ D'-D
being A, A', B, B', and so on, the coordinates for each point.
