Answer:
96
Step-by-step explanation:
Total number of people attending the history museum is 200
Surveyed people are 25
Out of the 25, 12 people said yes
Therefore; the fraction which said yes = 12/25
To find the total number of people expected to say yes out of those that attended the history museum;
Fraction of the sampled that said yes × total number of people that attended.
= 12/25 × 200
= 96
Answer:
x=8 and y = -11
Step-by-step explanation:
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
