S casts a "shadow" on the x-y plane given by the set
Each cross section is a square whose side length is determined by the vertical distance between y = 1 and y = x², which is |1 - x²|. But since -1 ≤ x ≤ 1, this distance simplifies to 1 - x².
The volume of an infinitesimally thin section is then (1 - x²)² ∆x (where ∆x represents its thickness), and so the volume of S is
The integrand is even, so this integral is equal to twice the integral over [0, 1] :
Let us assume that : 7 × 10⁶ is P times Greater than 4.5 × 10⁻¹
It means when we Multiply P with 4.5 × 10⁻¹, We should get 7 × 10⁶
⇒ (P × 4.5 × 10⁻¹) = 7 × 10⁶
⇒ 7 × 10⁶ is 1.56 × 10⁷ times Greater than 4.5 × 10⁻¹

Answer:
45 girls
Step-by-step explanation:
The ratio of girls to boys is 3:5
There are 120 children altogether
The number of girls is;
× 120 = 45 girls
The answer is a. two more than three times a number
