A bag contains 10 red marbles, 15 yellow marbles, 5 green marbles, and 20 blue marbles. Two marbles are drawn from the bag.
kherson [118]

Answer:

It is the third option: (10C1) (20C1( / 50C2.

Step-by-step explanation:

The number of ways of selecting 2 marbles = the number of combination of any 2 marbles in the 50 marbles in the bag and this is 50C2. It is combinations because the order of drawing the marbles does not matter.

The number of combinations  of one being red and the other blue =  10C1 times 20C1.

So the answer is (10C1) (20C1( / 50C2.

URGENT!: Which best explains why these two figures are similar or not similar?
-BARSIC- [3]

Answer:

These two figures are similar because \frac{5}{3} equals \frac{15}{9}.

Step-by-step explanation:

The figures will be similar if their ratios of the two sides are equal. So we need to check the ratios of the figures to see if they are similar or not.

For the smaller figure the ratio is \frac{5}{3}, and for the bigger figure the ratio is \frac{15}{9}. which upon simplification reduces to  \frac{5}{3}.

So we see that the ratios are equal. Thus the figures are similar.
