- (A) The following data was received from the Student Affairs Unit of the University
Concerning 100 students resident in Diamond hostel: 27 Students registered for Biology,
30 Students registered for Chemistry 18 Students registered for both subjects. With the
help of a Venn diagram, obtain the number of Students who registered for:
Chemistry; (ii) One subject only: (iii) Neither of the two subjects.

i) 30 students for chemistry

ii) 21 students for only one subject

iii) 61 students

Step-by-step explanation: from the question we got 30 students registered for chemistry. number students only for biology = (27-18) = 9

number of students only for chemistry = (30-18) = 12

number of student registered for only one subject = (12+9)= 21

number of students registered for neither two subjects = {100-(9+12+18)} = 61

42

step-by-step explanation:

256/6=42

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
