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.

Maitri and Aabhas do a work in 12 hours.
tamaranim1 [39]

Answer:

See below ~

Step-by-step explanation:

<u>Given</u>

  • Maitri and Aabhas do a work in 12 hours
  • Aabhas and Kavya do the work in 15 hours
  • Kavya and Maitri do the work in 20 hours

<u>Solving</u>

  • Take Maitri, Aabhas, and Kavya to be x, y, z respectively
  • <u>x + y = 12</u> (1)
  • <u>y + z = 15</u> (2)
  • <u>x + z = 20</u> (3)

<u>Take Equation 1 and rewrite it so that it is equal to x.</u>

  • x = 12 - y

<u>Take Equation 2 and rewrite it so that it is equal to z.</u>

  • z = 15 - y

<u>Now, substitute these values in Equation 3.</u>

  • x + z = 20
  • 12 - y + 15 - y = 20
  • -2y + 27 = 20
  • 2y = 7
  • y = 7/2 = <u>3.5 hours [Aabhas]</u>

<u></u>

<u>Substitute the value of y in Equation 1.</u>

  • x + 3.5 = 12
  • x = <u>8.5 hours [Maitri]</u>

<u>Substitute the value of y in Equation 2.</u>

  • 3.5 + z = 15
  • z = <u>11.5 hours [Kavya]</u>

<u></u>

<u>Add the values of x, y, and z together.</u>

  • x + y + z
  • 8.5 + 3.5 + 11.5
  • 12 + 11.5
  • <u>23.5 hours [together]</u>

Slope: -4-2/1-(-2)=-6/3=-2

Equation: y=-2x+b

Substitute: 2=-2(-2)+b

2=4+b

b=-2
