7 . 阅读材料:
在平面直角坐标系中,若点
与定点
(或
的距离和它到定直线
(或
)的距离之比是常数
,则
,化简可得
,设
,则得到方程
,所以点
的轨迹是一个椭圆,这是从另一个角度给出了椭圆的定义.这里定点
是椭圆的一个焦点,直线
称为相应于焦点
的准线;定点
是椭圆的另一个焦点,直线
称为相应于焦点
的准线.
根据椭圆的这个定义,我们可以把到焦点的距离转化为到准线的距离.若点
在椭圆
上,
是椭圆的右焦点,椭圆的离心率
,则点
到准线
的距离为
,所以
,我们把这个公式称为椭圆的焦半径公式.
结合阅读材料回答下面的问题:
已知椭圆
的右焦点为
,点
是该椭圆上第一象限的点,且
轴,若直线
是椭圆右准线方程,点
到直线
的距离为8.
(1)求点
的坐标;
(2)若点
也在椭圆
上且
的重心为
,判断
是否能构成等差数列?如果能,求出该等差数列的公差,如果不能,说明理由.

.现有如下定义:在n维空间中两点间的曼哈顿距离为两点
与
坐标差的绝对值之和,即为
.回答下列问题:
(1)求出n维“立方体”的顶点数;
(2)在n维“立方体”中任取两个不同顶点,记随机变量X为所取两点间的曼哈顿距离
①求出X的分布列与期望;
②证明:在n足够大时,随机变量X的方差小于
.
(已知对于正态分布
