Answer:
Step-by-step explanation:
The theoretical result is 0.2 * 20 = 4
The experimental result is 1/2 * 20 = 10
The difference is 10 - 4 = 6
The probability difference = 6/20 = 0.3
Answer:
Area = 3.3998
Perimeter = 2.9
Step-by-step explanation:
A method for calculating the area of a triangle when you know the lengths of all three sides.
Let a,b,c be the lengths of the sides of a triangle. The area is given by:
Area = √ p ( p − a ) ( p − b ) ( p − c )
where p is half the perimeter, or
a + b + c / 2
p = 1.7 + 1.7 + 2.4 / 2 = 5.8 / 2 = 2.9
a = Area = 3.3998
Heron was one of the great mathematicians of antiquity and came up with this formula sometime in the first century BC, although it may have been known earlier. He also extended it to the area of quadrilaterals and higher-order polygons.

The azalea is located at point (4, -4). You have already plotted the hydrangea at (4, 6). If you count up the number of squares from the hydrangea to the azalea plant, you will get a distance of 10.
Since the problem tells you the length of each square is 1 ft, then you know that the distance between the two plants is 10 squares * 1 ft/square = 10ft.
