Which set represents the
domain of the
function shown?
{(-3, 6), (0, 2), (4,
7), (11, 15)}
Select one:
a. {(6,-3), (2,0), (7,4),
(15, 11)
b. {2, 6, 7, 15)
c. {-3, 0, 4, 11)
d. (-3,0, 2, 4, 6, 7, 11,
15)

The correct answer is: c. {-3, 0, 4, 11}

Step-by-step explanation:

A function consists of ordered pairs. In the ordered pairs, the first element is the input and second value is the output.

All the possible set of inputs for a function are called domain.

Given function is:

{(-3, 6), (0, 2), (4, 7), (11, 15)}

The domain set will consist of the first elements of all the ordered pairs.

The domain of this function is: {-3,0,4,11}

Hence,

The correct answer is: c. {-3, 0, 4, 11}

-50/3 is the final answer! : )

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
