(A ∩ B) means "A intersection B". Your problem statement tells you the intersection contains
{3, 4}
You is not slow just read it and you will get it
Answer:
Step-by-step explanation:
AD and EH are parallel lines
Angle CBD = Angle CFH = x (corresponding angles)
x + 2x = 180 (angles on a straight line)
3x = 180
x = 60
Angle GFH = 120
Angle CBD = 60
To find the diameter, divide the area(254.34) by pi(3.1415) and then square the quotient


That is the radius now just times that by 2 so 2 x 8.99 = 17.98
Now I have a felling the might be wanting 18 because 8.99 is so close to 9 and this is also true for 80.95. They probably want 80.95 = 81, which the square root of that is 9, which is the radius and if you times that by 2 the diameter would equal 18
9 students earned an 85 or higher.
2 earned 85
1 earned 86
3 earned 91
1 earned 94
2 earned 95.
2+1+3+1+2=9
