1. Overview of the test questions
There are 11 multiple-choice questions in this question, and each question has five options. The test covers the basics of junior high school mathematics, including algebra, geometry, probability and statistics. The questions are moderately difficult and are designed to test students’ mastery of the basics.
2. Answer analysis
Here are the answers and explanations for each question:
1. [Answer] C
【Analysis】This question examines the algebraic simplification, according to the multiplicative distributive law, it can be reduced to the original formula = a×(b+c), so choose C.
2. [Answer] A
【Analysis】This question examines the properties of geometric figures, according to the properties of isosceles triangles, the two corners corresponding to the bottom edge are equal, so choose A.
3. [Answer] D
According to the definition of probability, the probability is obtained = the number of times a specific event occurs÷ the total number of times = 1/5, so choose D.
4. [Answer] B
【Analysis】This question examines the solution of the equation, and through the steps of shifting terms, merging similar terms, and converting coefficients to 1, x=3 can be solved, so B is selected.
5Ru-Đô. [Answer] E
【Analysis】This question examines the properties of the function image, and judges the function value according to the intersection point of the function image and the coordinate axis, so E is selected.
6. [Answer] C
【Analysis】This question examines logical reasoning, reasoning and analysis according to known conditions, and draws correct conclusions, so choose C.
7. [Answer] D
【Analysis】This question examines data analysis, analyzes and compares according to the given data, and draws correct conclusions, so D is chosen.
8. [Answer] A
【Analysis】This question examines the transformation of the figure, and judges the characteristics of the transformed figure according to the translation, rotation and other transformations of the figure, so choose A.
9. [Answer] B
【Analysis】This question examines the summation of the number series, and solves it through the sum formula of the equal difference number series, and the result is obtained, so B is selected.
10. [Answer] EBeach Life
【Analysis】This question examines the inequality solution, solves the inequality solution set through the inequality property, and obtains the option corresponding to the solution set range, so E is selected.
11. [Answer] D
【Analysis】This question examines the comprehensive application, solves practical problems by using mathematical knowledge, and obtains the correct answer according to the analysis of the problem conditions, so choose D.
3. Summary
