In a herd of 80 dairy cows, 16 have clack-and -white coats, and 64 have solid black coats. what is the frequency of cows with black-and-white coats?

20%

Explanation:

The frequency is the number of times a given thing appears in a specific period of time.

In the given situation, you have a total of 80 cows, amongst these 16 have black and white coat and 64 have solid black coats.

To find the frequency of black and white coats you need to simply find it probability.

This would be = No. of cows with black and white coats/ total number of cows

using this formula we get => 16/80 = 2/10

Therefore frequency in terms of percentage would be 2/10 X 100 = 20%.

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
