<h3> What is randomization?</h3>

Randomization allows a sample or small groups with similar characteristics to determine a probability or to hypothesize an event, that is why this type of sample is important in an experiment, that is, to carry it out in a random way.

If a crop at a certain time of year, for example in summer, is affected by a certain fungus, to know if it is really the time of year that affects this problem, random samples of the same crop with the same characteristics and put it to the test at another time of the year to see if the weather is really a risk factor in the spread of this fungus.

Use the formula A=bh , where A is the area, b is the base length, and h is the height of the parallelogram, to solve this proble
harkovskaia [24]
We know that:

A = 1440
H = 32

So you need to work backwards to find base.

1440 / 32 = 45

We can check our work:

32 x 45 = 1440

B = 45
