Answer:
Variability
Step-by-step explanation:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.
60-12-18-2-8=20
=48-18-2-8
=30-2-8
=28-8
=20
So, 20 students don't take either of these subjects.
♥ Solve:
(Arjun) 40*30=1200
(Dalia) 55*30=1650
Now subtract
1650-1200=450.
That means that Dalia will type 450 minutes more.
Final answer: 450
number of student attend the college are 3150
Step-by-step explanation:
the student teacher ratio is 35:2

according to the problem,
2x = 180
or, x = 180/2
= 90
so number of students = 35 X 90 = 3150
Answer:
Step-by-step explanation:
1/4 x 2 = 2/4
2/4 simplified = 1/2
