Which of the following is not a function?
rusak2 [61]
Answer: B

Number on the left: x-value
Number on the right: y-value

If there are 2 y-values for one x-value it is NOT considered a function.

For instance in the answer:

(2,3), (2,4), (3,3), (3,4)

You can clearly see that the x-values (2 & 3) repeat more than once; therefore, it is NOT a function.

On the other hand if you have 2 DIFFERENT x-values for the same y-value it IS A FUNCTION.

For ex D: (2,4), (3,4), (5,4), (6,4)

As you can see there are 4 DIFFERENT x-values with same y-value; therefore it is A FUNCTION

To make it easier:

If x-values appear more than once = NOT A FUNCTION

If x-values appear only ONCE = FUNCTION

Remember: y-values are ALLOWED to repeat

I hope this helps. If you have any questions please let me know in the comments.

Ira Lisetskai [31]

Answer:

C. 3.2

Step-by-step explanation:

Heights of dogs: 10, 22, 15, 12, 16

✔️Find the mean of the data set = \frac{10 + 22 + 15 + 12 + 16}{5} = \frac{75}{5} = 15

✔️Find |data value - mean|:

|10 - 15| = 5

|22 - 15| = 7

|15 - 15| = 0

|12 - 15| = 3

|16 - 15| = 1

✔️Find the sum of |data value - mean| and divide by 10:

\frac{5 + 7 + 0 + 3 + 1}{5} = \frac{16}{5} = 3.2

✅M.A.D = 3.2

Use this formula:  d= \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }

a)  d=11

Work:
d=sqrt((4-(-7))^2+(5-5)^2
d=sqrt((11)^2+(0)^2)
d=sqrt(121+0)
d=sqrt(121)
d=11

b) d=4

c) d = 16

d) d=160

e) d=12
