Answer:
12
Step-by-step explanation:
To find the mean, add up all the numbers
18+ 19+ 19+ 4+14+ 8+ 22+ 3+ 1
108
Then divide by the number of terms
108/9 =
12
Answer:
The second group
Step-by-step explanation:
The first group is 4 apples for 3 friends.
= 4/3. They each got 1 & 1/3 of an apple.
The second group is 6 apples for 4 friends.
= 6/4. They each got 1 & 1/2 of an apple.
1 1/3 < 1 1/2, so friends in the second group get a larger portion of apples

Answer:
B
Step-by-step explanation:
Any inversely proportional equation is of the form y=k/x.
Answer:
The given function is a nonlinear function because the degree of the function is 2 and we get same value of y for more than one values of x.
Step-by-step explanation:
The given function is

To find the points which lie on the function, put difference values of x in the given function and find the values of y.
Put x= -2

Put x= -1

Put x= 0

Put x=1

Put x= 2

The table of values is shown below.
Plot these points on a coordinate plane and connect them by a free hand curve.
The given function is a nonlinear function because the degree of the function is 2 and we get same value of y for more than one values of x.
The graph of function is shown below.
