Mariam is making
ira [324]

Answer:

  no

Step-by-step explanation:

A trapezoid is shown, not a bag. If we assume that this shape is supposed to be the front of the bag, Mariam does NOT have enough pink fabric to make the front of the bag from pink fabric.

The area of the trapezoid shown is ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(9 in + 8 in)(15 in) = 127.5 in^2

This area is larger than the amount of fabric Mariam has, so she does not have enough.

A non random sample refers to a sampling method that is not based on chance alone. A biased sampling is one in which some members of the population are more likely to be selected thereby excluding the others.
