in an examination 80%students passed in physics 70% in chemistry while 15% failed in both the subjects. if 3250 students passed in both the subjects. find the total number of students who appeared in examanitaion

5,000 students (hope this helps!)

Step-by-step explanation:

3250 students passed in both subjects

x is the percentage of students that passed in both subjects

total=100%

Passed students=100-15(failed students)=85

85 is the passed students so

passed students in both subjects x= 80+70-85=65

Now x=65

65% of total students=325

.°. Total students = 3250×100/65=5000

Ans. There were a total of 5000 students.

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

your answer would be 12
