计算排名的函数不会是哪个? A: rank B: rank.eq C: rand D: rank.avg

‏函数rank()和函数rank.eq()的功能完全相同，都是在不打乱记录顺序的情况下完成排名操作。（ ）​

公式=RANK.EQ(A3，A3：A20，1）的功能是

‎If A and B are m × n matrices then have the same rank, then the rank of AB must equal the rank of BA.‌‎‌

库面板可以存储（ ）。1.各种元件 2.声音3.位图4.视频 A: eq \o\ac(○,1)1 B: eq \o\ac(○,1)1、 eq \o\ac(○,2)2、 eq \o\ac(○,3)3 C: eq \o\ac(○,2)2、 eq \o\ac(○,4)4 D: eq \o\ac(○,1)1、 eq \o\ac(○,2)2、 eq \o\ac(○,3)3、 eq \o\ac(○,4)4

RANK.EQ 函数完成的是排名系列函数中的

已知Eq(BrO3-/Br2)=1.48 V，Eq(HBrO/Br2)=1.60 V，求Eq (BrO3-/HBrO)=____V。

以下语句错误的是() A: LECT rank, AVG(salary) FROM people HAVING AVG(salary) > 1000 GROUP BY rank; B: SELECT rank, AVG(salary) FROM people GROUP BY rank HAVING AVG(salary) > 1000 C: SELECT rank, AVG(salary) FROM people HAVING AVG(salary) > 1000 GROUP BY rank; D: SELECT AVG(salary) FROM people GROUP BY rank HAVING AVG(salary) > 1000; E: SELECT rank, AVG(salary) FROM people GROUP BY rank WHERE AVG(salary) > 1000;

Let A be an m×n matrix, then ( ). A: AAT =ATA. B: if rank(A) = m, then AT A is invertible. C: if rank(A) = n, then AAT is invertible. D: if rank(A) = n, then AT A is invertible.
