during the sports period 1/4 of the students in class were playing chess and 1/3 of the students were playing badminton the remaining 15 students play football what is the total number of students in the class

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
