First i will build the envelope. for this, i am using a rectangular piece of material 28m long and 12m wide. out of this material, i have to cut patches that are 1/12 the length and 2/15 the width of the whole material. what is the area of a patch and how many such patches can i make out of the whole material?

3.728 cm²

90

Step-by-step explanation:

To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.  

Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.

So, the length of the patches is m and the width of the patches is m.

Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)

Now, the area of the rectangular piece of material is (28 × 12) = 336 m²

Hence, ≈ 90 such patches can be made out of the whole material. (Answer)

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
