the number of ways 15 students can be selected from a class of 32 students

Here the number of students to be selected = 15

And the total number of students = 32

So the Number of ways 15 students can be selected from a class of 32 students should be

32 C 15 ,

it means we have to solve 32 C 15 ,

for this we need to see the 15th row of the pascals triangle.

Abdul is working on a project and has cut a number of wooden blocks of equal size that are represented by this right rectangular
Valentin [98]

The amount of fabric needed to cover 8 blocks is 192cm.

<h3>How much fabric is needed to cover 8 blocks?</h3>

In order to determine the amount of fabric needed, the total surface area of the rectangular prism has to be determined. The total surface area of the rectangular prism is the sum of the areas its faces.

Total surface area of a rectangular prism = 2 (lw + wh + lh)

where:

  • l = length
  • w = width
  • h = height

2 x [(4 x 1/2) + (1/2 x 2) + (4 x2)] = 24cm

Fabric needed fo 8 blocks = 24 x 8 = 192cm
