Which relation is a function?

Mathematics
1 answer:
kirill115 [55]1 year ago
7 0

Answer:

Step-by-step explanation:

The graph certainly is, if you ignore the fact that you don't know what the equation for the graph is.

Each x has only 1 y associated with it. That's the definition of a function. This one presumably follows that definition, but I caughten you, without the equation, you can't be sure.

What is the mean? If the answer is a decimal, round it to the nearest tenth.
Semmy [17]

Answer:

The mean is 52.

Step-by-step explanation:

The mean is the sum of all elements divided by the number of elements.

In this problem, we have that:

Elements

56 47 48 52 62 59 49 56 43 48

Sum

56+47+48+52+62+59+49+56+43+48 = 520

Number of Elements

10 elements

The mean is

M = \frac{520}{10} = 52

Say you have 50k and you spend 73% of it how much do you have left
Vadim26 [7]

50k is the same as 50,000

73% = 73/100 = 0.73

Multiply 50,000 with 0.73

50,000 x 0.73 = 36500

You spend $36500.

Subtract 36500 from the total

50,000 - 36,500 = $13,500

$13,500 is the amount of money you have left.

hope this helps
