Identify which of these designs is most appropriate for the given​ experiment: completely randomized​ design, randomized block​d
sasho [114]

Answer:

Matched pairs design

Step-by-step explanation:

Looking at the options;

-It's not a completely randomized design because a randomized design will assign all individuals to a group which in this case it doesn't.

- It's not a randomized block design because randomized block design will group the subjects in question into 2 or more blocks which have a common characteristic and will then randomly assign subjects in each of the blocks.

-It's a matched pair because every individual/subject undergoes measurements both before and after being treated with the drugs.

Thus, the correct option is matched pairs design.

a rectangular pool is 20 ft wide and 50 ft long. the deck is the same width all the way around the pool. the total area of the d
Alex
First, we need to get the total area of the rectangular pool.
Area = l * w
Area = 20 ft * 50 ft
Area = 1000 ft^2

Then the deck is 456 ft^2 with the width of 20ft, the same as the rectangular pool.

Area = l * w
456 = l * 20
l = 456 / 20
l = 22.8 ft.

So the walkway is 22.8ft wide.
