Answer:

$\dfrac{2}{7}$

Step-by-step explanation:

3 different china dinner sets, each consisting of 5 plates consist of 15 plates.

A customer can select 2 plates in

$C^{15}_2=\dfrac{15!}{2!(15-2)!}=\dfrac{15!}{13!\cdot 2!}=\dfrac{13!\cdot 14\cdot 15}{2\cdot 13!}=7\cdot 15=105$

different ways.

2 plates can be selected from the same dinner set in

$3\cdot C^5_2=3\cdot \dfrac{5!}{2!(5-2)!}=3\cdot \dfrac{3!\cdot 4\cdot 5}{2\cdot 3!}=3\cdot 2\cdot 5=30$

different ways.

Thus, the probability that the 2 plates selected will be from the same dinner set is

$Pr=\dfrac{30}{105}=\dfrac{6}{21}=\dfrac{2}{7}$

Given: Angle 2 and Angle 3 are a linear pair. Angle 3 and Angle 4 are a linear pair. Prove Angle 2 is congruent to Angle 4.

Pachacha [2.7K]

Reason 2 is that they are linear, so they form 180 degrees, which makes them supplementary. Reason 3 is that they are both 180 - angle 3. I think. I'm not sure about reason 3.

The old price per ounce is c/4.

The new price per ounce is c/3.6.

The ratio of the old price to the new one is

... (c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . . . = 9/10 . . . "nine tenths" in either form
