4. 1-= (m) is an isosceles triangle.

5.( 1) Average value: (9.6+9.4+9.6+9.6+9.9+9.7+9.3+9.6+9.5) ÷ 9 = 9.58.

Median: 9.6 Mode: 9.6

(2)(9.6+9.4+9.6+9.6+9.7+9.6+9.5)÷7=9.57

Six, hands-on practice

This topic should pay attention to the specifications of 1 square with a side length of 3 cm, and mark the condition of 3 cm on the side length.

2. There are different ways to divide it into eight parts on average, and any method will do, but the condition is that it must be divided equally, and five of them are shaded.

Third, the test paper scoring standard

1 coil surface requirements.

(1) The handwriting is neat and the format is standard.

2. Fill in the blanks.

If the fill-in-the-blank question is empty, then only the number and the unit name are correct can you get the corresponding score, otherwise you won't score.

3. Scoring criteria for analysis questions.

If the result is incorrect, no score will be given.

4. merit-based admission.

If the result is incorrect, no score will be given.

5. calculation questions. Write the number directly. If the result is wrong, don't score.

6. Off-mold calculation. Give points according to the steps, and give points according to the proportion of the scores. If the steps are correct and the results are wrong, deduct 1 minute. Others should be considered as appropriate according to the requirements of the topic, and those that require simplification should be simplified, otherwise points will be deducted.

7. Look for the unknown. Write the word "solve", otherwise 0.5 points will be deducted.

8. Scoring criteria for solving problems.

(1) If the formula is correct, the calculation is correct, the unit is reasonable, and the answer is complete, full marks will be obtained.

(2) If the formula is correct and the calculation is incorrect, points will be deducted according to the score proportion.

(3) 0.5 points will be deducted if the unit is incorrect or omitted.

(4) 0.5 points will be deducted if the answer is incomplete.

9. hands-on practice. You can draw a square for a point. Divide the square into 8 parts and give 2 points. Shading gives 2 points.
