What did I do wrong, it says I'm wrong

Mathematics
1 answer:
Alisiya [41]3 years ago
7 0

Answer:

This is not a function.

Step-by-step explanation:

Note, that set A contains 3 elements that only map to 2 elements in set B.  A function would require that each element of set A to match to only one element of set B.

Since set B contains an element with no mapping to an element in set A, this does not represent a function.

Answer:

Tomas is incorrect.

Step-by-step explanation:

Example : If we divide a cake into 8 pieces and a similar cake is into 4 pieces, a piece of cake taken from 4 pieces will be bigger than a piece taken from 8 pieces.

Similarly, size of 3 pieces of cake taken from 4 pieces will be bigger than the 3 pieces taken from 8 pieces.

Therefore, \frac{3}{4} will be greater than \frac{3}{8}.

Tomas is incorrect.

Simplify the expression
NeTakaya

First, solve the parenthesis

Remember to follow PEMDAS, and the left-> right rule

12/3 = 4

4 x 2 = 8

8 + 3 = 11

11 - 7 = 4

Square the remaining number

4² = 4 x 4 = 16

16 is your answer

hope this helps

If the original quantity is 10 and the new quantity is 11, what is the percent crease?
LenKa [72]

Answer:

10 %

Step-by-step explanation:

We first find change in the quantities

Then we write the change in quantity on original quantity and multiply by 100%

This implies that,

\frac{11 - 10}{10} \times 100\%

=\frac{1}{10}\times100\%

=10\%

Therefore the percentage increase is 10%
