(It is best to have test questions) Chinese composition topics Fill-in-the-blank question: This big question is a small question of *** 14, with 5 points for each small question and 70 points for * * *. Please fill in the answer directly in the corresponding position on the answer sheet.

1.？ Given a set, then = ▲.

2. It is known that (a∈R, imaginary unit), if the corresponding point of complex number Z on the complex plane is on the real axis, then

a= ▲ . 1

3. If the distance from the point on the parabola to the focus is 6, then p =▲8.

4. The function is known. Randomly choose one in the interval so that the probability is ▲.

5. If the inclination of the straight line is obtuse, the range of real number is ▲.

6. Seven judges of a teacher's basic skills competition in a city made a stem leaf diagram of scores for a player.

As shown in the figure, the five data after the highest score and the lowest score are removed.

The standard deviation is ▲. (The stem stands for ten digits, and the leaf stands for one digit)

7. If the program block diagram shown in the figure is executed, the output value of A is ▲.

8. Given that the included angle between unit vectors A and B is 120, the minimum value of is ▲.

9. If the terminal edge of a known angle passes through this point and the distance between two adjacent symmetry axes is equal, then = ▲.

10. All terms are positive geometric series. If the derivative of the function is, then ▲.

1 1. If the moving point P is on the straight line l 1: and the moving point Q is on the straight line l2:, let the midpoint of the straight line PQ be ≤8, then the value range of is ▲. [8, 16]

12. It is known that the side lengths of cube C 1 are C2, C3, C4, etc. Remember that the side length of convex polyhedron Cn is an, then A6 = ▲.

13. If it is a function, the number of heterozeros of the function on (0, 1) is ▲3.

14. It is known that the radius of a fan-shaped AOB with a central angle of 120 is 1, where c is the midpoint of, and points D and E are on radii OA and OB respectively. If so, the maximum value of is ▲.

The Chinese answer is CBCCB.
