若数据表中C列数据为性别,1表示男性, 2表示女性,为方便查看,现需在D列利用函数计算出对应性别,则D2单元格应输入公式为( )
A. =IF(C2=1,"男",IF(C2=1,"女"))
B. =IF(C2=1,男)
C. =IF(C2=1,男,女)
D. =IF(C2=1,"男","女")
函数MID(“student”,3,3)的值是( )
A. stu
B. tud
C. ude
D. den
如何用IF嵌套完成成绩从百分制转换成五级制。(90-100为优,80-89为良,70-79为中,60-69为及格,少于60为不及格)假定A2-A55放置百分制成绩,B2-B55放置转换后成绩,请问B2中函数应为()
A. =IF(A2>90,"优",IF(A2>80,"良",IF(A2>70,"中",IF(A2>60,"及格","不及格"))))
B. =IF(A2>=90,优,IF(A2>=80,良,IF(A2>=70,中,IF(A2>=60,及格,IF(A2<60,不及格)))))
C. =IF(A2>=90,"优",IF A2>=80,"良",IF A2>=70,"中",IF A2>=60,"及格","不及格")
D. =IF(A2>=90,"优",IF(A2>=80,"良",IF(A2>=70,"中",IF(A2>=60,"及格","不及格"))))
