The following subsets you can be able to create are:
{1}
{2}
{3}
{1,2}
{1,3}
{2,3}
{1,2,3}
Therefore, there are 7 subsets in all. However, we don't have to list all these possible outcomes because we could waste our time doing this but there is a formula, that is 2^n - 1 where n is a number of elements.

In the given, since there are 3 elements inside the set then we use 2^3 - 1 = 8 - 1 = 7.
See...it's easy.

Answer:

The correct option is d.

Step-by-step explanation:

The given set is {1, 2, 3}.

If a set has n elements , then the formula for number of subsets is

Number of subsets = 2^n

In the given set the number of elements is 3. So the number of subsets is

Number of subsets = 2^3=8

The number of subsets is 8. The subsets are

1. {}

2. {1}

3. {2}

4. {3}

5. {1,2}

6. {1,3}

7. {2,3}

8. {1,2,3}

Therefore the correct option is d.

Jasmine is part of a bowling league and wants to beat the team record of an average score of 240 out of 300 possible points per
hoa [83]

Answer:

her score in sixth game is 270

Step-by-step explanation:

The computation of the Jasmine score in her sixth game is shown below:

Let us assume her sixth game score is x

And, the first five games are 252, 227, 210, 239, 242

And, the average score is 240

So, the following formula should be used

(252 + 227 + 210 + 239 + 242 + x) ÷ 6 = 240

252 + 227 + 210 + 239 + 242 + x = 240 × 6  

252 + 227 + 210 + 239 + 242 + x = 1,440

x = 270

Hence, her score in sixth game is 270
