For this case we must find

By definition we have to:

We have the following functions:

Now, applying the given definition, we have:

Answer:

Hi there!

Find the perimeter using the formula:
P = 2l + 2w
It is given that the dimensions are 2.8 × 1.9 so plug these number into the equation:
P = 2(2.8) + 2(1.9)
P = 5.6 + 3.8
P = 9.4m
Calculate a simple probability p=x/n, here x is the defective,so the answer is 4/50
The standard form is 21x-y-7=0
