Find out the odd one. 
Let’s analyze the given options one by one:
- Option A: The shape inside the box in option A has a triangle and a circle, which is different from other shapes that involve a combination of different geometric shapes (square, triangle, and circle).
- Option B: The shapes in the box involve a circle, square, and triangle, and follow a similar pattern as the other options.
- Option C: Similarly, option C involves different shapes (circle, square, and triangle) in different orientations.
- Option D: This option is the most different as it involves a circle and square, with the other shapes (triangle) placed differently.
Thus, option A is the odd one out as it doesn't follow the same pattern of shapes as the others.
Final Answer: (D) A
If for \( 3 \leq r \leq 30 \), \[ \binom{30}{30-r} + 3\binom{30}{31-r} + 3\binom{30}{32-r} + \binom{30}{33-r} = \binom{m}{r}, \] then \( m \) equals: ________
Let \[ \alpha = \frac{1}{4} + \frac{1}{8} + \frac{1}{16} + \dots \infty \] and \[ \beta = \frac{1}{3} + \frac{1}{9} + \frac{1}{27} + \dots \infty. \]
Then the value of \[ (0.2)^{\log_{\sqrt{5}}(\alpha)} + (0.04)^{\log_{5}(\beta)} \] is equal to: ________
Let \( y = y(x) \) be the solution of the differential equation:
\[ \frac{dy}{dx} + \left( \frac{6x^2 + (3x^2 + 2x^3 + 4)e^{-2x}}{(x^3 + 2)(2 + e^{-2x})} \right)y = 2 + e^{-2x}, \quad x \in (-1, 2) \]
satisfying \( y(0) = \frac{3}{2} \).
If \( y(1) = \alpha \left(2 + e^{-2}\right) \), then the value of \( \alpha \) is ________.
