A fair con is tossed 80 times in an experiment. If the coin is fair, what would be a reasonable number of times tails should appear
based on your knowledge of the theoretical probability of this event?
Answer: 40 would be a reasonable number of times tails should appear if the coin is fair. Fair means 50/50 chance.

The perimeter of a rectangle is 26 inches. If the length of the rectangle is 6 inches, find the width.
Answer:
7 inches
Step-by-step explanation:
The perimeter of a rectangle = 2 x ( length + breadth)
26 = 2 x (6 + breadth)
Divide both sides of the equation by 2
26/2 = 6 + width
13 = 6 + width
Collect like terms
13 - 6 = width
width = 7 inches

the answers are 13, ab/2, 20 and 15x²/2
Answer:
1/2 a^2, 1/2 b*a , 20, 7.5x^2
Step-by-step explanation:
Area of right angle triangle = 1/2 height * base so
Area of MSP = 1/2 a^2 , Area of BUC =1/2 a*b
Area of BAC =1/2 8*5 , Area of DRK =1/2 3x*5x =1/2 *15x =7.5x^2
Find the area in the pic please!!
Answer:
Area = 970 ft²
Step-by-step explanation:
The shape is composed of a square and a triangle.
Therefore:
Area of the shape = area of square + area of triangle
✔️Area of square = s²
s = 20 ft
Area = 20²
Area of square = 400 ft²
✔️Area of triangle = ½*b*h
b = 20 + 9 + 9 = 38 ft
h = 30 ft
Area of triangle = ½*38*30 = 570 ft²
✅Area of the shape = 400 + 570 = 970 ft²
