Answer:
There are 35 students in the class
Step-by-step explanation:
We would divide 21 by 60%
21/0.6 = 35 students.
35 students are in the class
21/x 60/100
cross multiply so you will get
2100 = 60x
divide each side by 60x
2100/60 = 35
21 students out of 35
20,25,30,30,31,40,41,49
median=30.5
Q¹= 27.5
Q³=40.5
40.5-27.5= 13 IQR = 13
Y=-5/3x-1
y=2/3x-8
If you are adding then it is:
7x=21
x=3
5x+3y=-3
3y=-5x-3
y=-5/3-1
2x-3y=24
-3y=-2x+24
6/8×100=75%
100-75=25
the answer is 25
The rational number 1 is the multiplicative identity for rational numbers.
I hope this will help you buddy
