最佳答案波段方程

1.设这个数为x。

6.4x+2.6=6.1

6.4倍=3.5倍

x=0.546875

2.设解的个数为x。

2x-7/5-65438/7+0x = 3/2。

三十个中的八个8x=2个中的三个

x=35中的X = 12。

3.设这个数为x。

75%x-1.8×5=4.5

75%x×9=4.5

x=6

4.35÷40×(四分之一)=0.4375

5.(1.3+ 4/5) ÷(3- 2/3) = 65438+9/00

6.省略(不会)

7.设这个数是x .

4/9 x-1.2 x 5/3 =1.6

4/9 x- 2/5 =1.6

4/9 x=2

X= 9/2

8.设这个数是x .

1.5x=(3.1+0.5)×6

1.5x=3.6×6

1.5x=21.6

x=14.4

9.(4.5÷ 3/8 +8)×6=120

10.(9/2× 2/3 -1.5)÷1.5=1.

11.五十六三分之(四十的七分之五)=三分之一。

问题挺难的，呵呵。最后打出来一定要选我！

家庭作业3(第5-7章)1。是非题1、× 2、× 3、√ 4、× 5、√ 6、√ 7、√ 8、× 2、单项选择题1、A 2、C 3、D 4、C 5、C 6、B 7。选择题1，ABCD 2，ACD 3，BC 4，ABCE 5，BDE 6，AD 7，ABCD 8，BCDE 9，ABD 10，ACE IV，简答题1，什么是抽样误差？影响抽样误差的因素有哪些？答:抽样误差是指由于抽样的偶然因素，造成抽样指标与总量指标之间的绝对偏差，使样本单位的结构不足以代表整体单位的机构。影响抽样误差的因素有:整体中各单元标志值的差异、样本中的单元数、抽样方法和抽样调查的组织形式。2.什么是抽样平均误差和抽样极限误差？两者是什么关系？答:平均抽样误差是反映抽样误差总体水平的指标；抽样极限误差是反映抽样误差最大范围的指标，两者既有联系又有区别。它们之间的关系是:极限误差是在抽样平均误差的基础上计算的，即；两者的区别是:(1)含义不同；(2)影响误差的因素不同；(3)计算方法不同。3.请写出相关系数的简要公式，并说明相关系数的取值范围及其判断标准。答:相关系数的简单公式:(1)相关系数的数值范围在-1到+1之间，即(2)判断标准:，，；不相关，完全相关。4.拟合回归方程yc=a+bx的前提条件是什么？写出参数A和B的计算公式并说明经济意义。答:拟合线性回归方程的要求是:(1)两个变量之间确实存在线性相关关系；(2)两个变量之间的相关性必须是显著的；(3)寻找合适的参数A和B，使确定的回归方程能使实际Y值与相应理论值的偏差平方和最小。回归方程中，参数A代表直线的起点，数学上称为直线的纵向截距，它代表x=0时y的常数项。参数b称为回归系数，表示自变量x增加一个单位时，因变量y的平均增加量。回归系数的符号与相关系数的符号是一致的，所以我们可以从回归系数的符号来判断两个变量的相关方向。不及物动词计算题1。答案见学习指南第344页第二个计算题。2.答案请参考学习指南第348页第8道计算题。3.答案请参考学习指南第352页的计算题17。4.求解:(1)样本合格率=平均抽样误差= (2)抽样限误差△p=产品合格率区间:下限=p-△p=上限=p-△p= 5。答案见学习指南第73页的计算题。6.答案请参考学习指南第360页第三道计算题。7.答案请参考学习指南第363页第7道计算题。
