1/2 is the probability, or 50%. There are 4 teams of S and B n the Y, 2 are B. so its 2/4
Area of a rectangle can be calculated by multiplying the length by the height.
So:
l x w
3 x 13
39 cm squared
Area of a triangle can be calculated by multiply the length by the height and dividing by two. So:
1/2 x l x w
1/2 x 10 x 8
40 m squared
8 because the line is going up by 1 as seen from 4 and 6
For f(x)=ax^2+bx+c
the axis of symmetry is -b/2a
f(x)=2x^2+4x+2
a=2
b=4
-4/(2*2)=-4/4=-1
the axis of symmetry is x=-1
B
1. 3
2. -9
3. negative, loss was -6
