The table represents the cost of flowers at the tigerlily flower shop.

quantity price
1 2.00
2 3.50
3 5.00
4 6.50
5 8.00
6 9.00
which graph is the best interpretation of this table?
(the table is messed up a bit but the decimal numbers are the price and the 1,2,3,4,5, and 6 are quantity.)

The correct option is 1.

Step-by-step explanation:

The given table is

Quantity(x)     Price(y)

    1                  2.00

    2                 3.50

    3                 5.00

    4                 6.50

    5                 8.00

    6                 9.00

It means the points on the graph are (1,2), (2,3.50), (3,5), (4,6.50), (5,8) and (6,9).

The graph 1 represents all the above mentioned point, therefore option 1 is correct.

According to the graph 2, at quantity 6 the price of flower is 12, which is not correct. Therefore option 2 is incorrect.

The quantity of flower is always a whole number. So the graph is defined on the whole numbers only. It means the graph is a scatter plot instead of a curve of a straight line.

Therefore the option 3 and 4 are incorrect.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
