Answer:

C. No, because one x value corresponds to two different y values.

Step-by-step explanation:

We are given a table having value of x and y such that it forms a function.

Now, we know that a 'function' is a mapping from domain to the co-domain such that every value of the domain is mapped to a unique value of the co-domain.

According to our table, we can see that corresponding to the point x = 5, there are two different values y = 2 and y = 5.

So, this table does not represents a function.

Hence, option C is correct.

A polynomial is factored using algebra tiles

dezoksy [38]

Answer:

A) $x^2-2x-8$

Step-by-step explanation:

The polynomial factored is equal to the area of the algebra tiles. This means the quadratic is

$x^2 + x+ x -x -x -x -x-1-1-1-1-1-1-1-1\\x^2-2x-8$

After writing out each tile as a term, combine like terms to simplify. This ia the quadratic.

$x^2-2x-8$

This table shows the number of points two teams scored in five games

mezya [45]

Answer:

2.16

Step-by-step explanation:

The question is on mean absolute deviation

The general formula ,

Mean deviation = sum║x-μ║/N where x is the each individual value, μ is the mean and N is number of values

Team 1

Finding the mean ;

$mean= \frac{51+47+35+48+64}{5} =49$

Points Absolute Deviation from mean

51 2

47 2

35 14

48 1

64 15

Sum 34

Absolute mean deviation = 34/5= 6.8

Team 2

Finding the mean

$mean=\frac{27+55+53+38+41}{5} = 42.8$

Points Absolute deviation from the mean

27 15.8

55 12.2

53 10.2

38 4.8

41 1.8

Sum 44.8

Absolute deviation from the mean = 44.8/5 =8.96

Solution

Difference in mean absolute deviation of the two teams = 8.96-6.8 = 2.16
