纸的厚度 | 1张纸厚 | 2张纸厚 | 3张纸厚 | 4张纸厚 | 5张纸厚 | |
抗弯曲能力的大小(放垫圈的个数) | 观测 | 1 | 4 | 8 | 12 | 16 |
实测 | 2 | 8 | 15 | 25 | 40 |
1.把实测的数据制成折线统计图。
2.分析实测的数据和折线图,请你做出合理的解释:
同类型试题
y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
