Answer:
7p^2 - 3p - 3
Step-by-step explanation:
the simplified version of the expression is 7p^2 - 3p - 3
A square has all the sides being equal.
Since the top can fit 3 color tiles, then the side must fit the same number of tiles.
Therefore, 3 roles and 3 columns of tiles will be required.
The number of tiles required will calculated similar to area of a square. That is,
Number of tiles = 3*3 = 9 tiles.
Given:
circle inscribed in a square.
Side length of the square = diameter of the circle.
Let x side length and diameter.
Area of a square = x²
Area of a circle = πr²
r = radius ; half of the diameter. = x/2
Area of a circle = π * (x/2)² or π (x²/4)
Ratio of the area of the square to the area of the circle
x² : π(x²/4) or x² / πx²/4
x² * 4/πx² = 4/π
Answer:
Theoretical probability. 1/13
Step-by-step explanation:
probablility = number of favorable outcomes/number of possible outcomes
Since there are four 5's in a deck, this will be the numerator and since there is 52 cards in a deck this will be the denominator.
(p of drawing a 5) = 4/52
Simplify the fraction by dividing the numerator and denominator by 4
4/52 ÷ 4/4 = 1/13
This is theoretical probability because you are not actually drawing the cards.
