"Mean" is another way of saying average.
To find the average/mean, add up all the numbers and then divide by the amount of numbers that are in the data set.
Step 1: Add the numbers.
0 + 1 + 1 + 2 + 5 + 6
= 15
Step 2: Divide the sum by the amount of numbers in the set.
There are 6 numbers in the data set.
Their sum is 15.
Divide 15 by 6.
15 / 6
= 2.5
Answer:
The mean, also known as average, of this data set is 2.5.
Hope this helps!
Answer:
A
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b [ = [ 3, 5 ]
From the table
f(b) = f(5) = - 26
f(a) = f(3) = - 10
Hence average rate of change
= 
= 
= - 8 → A
Answer: 38.2
Step-by-step explanation:
Answer:
17 students per teacher, 9 students per tutor. You need 10 tutors if the school had 90 students.
Step-by-step explanation:
51 students divided by 3 teachers = 17 students per teacher.
45 students divided by 5 tutors = 9 students per teacher.
If there are 9 students per tutor 9 * 10 = 90 so ten tutors
Answer:
2. X = 13 1/3
Step-by-step explanation:
(3/2) times x - 4 = 16/ - 16
(3/2) times x - 16 - 4 = 0
3/2 times x - 20 = 0/ + 20
3/2 times x = 20 / : 3/2
x = 20/3/2
x = 40/3 = 13 1/3
