Answer:

Step-by-step explanation:

    Remember the SAS rule is that you know the measure of 2 sides and their angle in between. (Note that SSA side side angle DOESN'T work.)  For the first question we know that sides JH and LM are congruent, and sides GJ and MK are as well. Secondly, we know that angles M and J are congruent. The question is; does this problem follow the SAS (side angle side) rule? Yes, their are two proven congruent sides on the two triangles, and the angle between them is proven congruent as well.

Second one is congruent because it follows the SSS rule (side side side) ie: all sides are congruent, so therefore the triangles are congruent.

Think about the third one. Is it congruent or not. (To be congruent it has to follow SSS, or SAS) Comment below so I can correct you.

What is the probability of getting 2 of the same colour?

PLZ answer fast urgant help needed!

Answers

Answer:

0.5041 = 50.41% probability of getting 2 of the same colour

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

What is the probability of getting 2 of the same colour?

Both blue or both red

Since they are replaced, we have, in each trial:

6 blue from a set of 6 + 5 = 11

5 red from a set of 6 + 5 = 11

Probability of both blue:

Each with 6/11 probability. So

[tex]P = (\frac{6}{11})^2 = \frac{36}{121}[/tex]

Probability of both red:

Each with 5/11 probability. So

[tex]P = (\frac{5}{11})^2 = \frac{25}{121}[/tex]

Total:

[tex]p = \frac{36}{121} + \frac{25}{121} = \frac{61}{121} = 0.5041[/tex]

0.5041 = 50.41% probability of getting 2 of the same colour

The floor area is found by multiplying its length by its width: 6*5=30

The amount of area covered by one tile is found by multiplying its length by its width: 3*w=3w.

Ten tiles are used to cover the floor, so the floor area should be equal to ten times the tile area:

The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10.
