What can you conclude from the diagram
sveta [45]

Answer:

You can conclude from the diagram that m∠P is less than m∠N ⇒ A

Step-by-step explanation:

  • In any triangle, you can arrange the lengths of the sides according to the measure of the opposite angles
  • In any triangle, you can arrange the measure of the angles according to the lengths of the opposite sides

<u><em>Example:</em></u>

In ΔABC, if the arrangement of the sides is AB < BC < CA, then the arrangement of the measures of the angles is m∠C < m∠A < m∠B

Let us use this fact to solve the question

→ In ΔKNP

∵ KP = 8 units

∵ KN = 6 units

∵ 6 < 8

∴ KN < KP

∵ ∠P is opposite to the side KN

∵ ∠N is opposite to the side KP

∵ KN < KP

→ By using the fact above

∴ m∠P < m∠N

∴ m∠P is less than m∠N

∴ You can conclude from the diagram that m∠P is less than m∠N

The table represents the cost of flowers at the Tigerlily Flower Shop.
Afina-wow [57]

Answer:

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.
