Answer:
(1,1)
Step-by-step explanation:
M=(x1+x2 / 2 , y1+y2 / 2)
M=(-2+4 / 2 , 4+ -2 / 2)
M=(2 / 2 , 2 / 2)
M=(1,1)
Just take the shape and make it upside down and thats a 180
The solution for this problem is:
One way to solve is to using the "stars and bars"
approach, but this could be the other one:
x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9 + x10 = 20
then use (20+10-1) C(10-1), this will
result to 29C9.
Then find the way to distribute x
as a result, (20-10+10-1) C (10-1) = 19C9
Thus, the probability is 19C9/29C9 or 0.0093
Answer:
65 km/hr
Step-by-step explanation:
The average of numbers can be calculated by adding them up and dividing that by how many numbers there are.
Here, we have two numbers. Therefore, we first add them (55+75 = 130) and then divide by 2 because there are 2 numbers, so 130/2 = 65
