One cubic yard is equal to 27 cubic feet because one yard is equal to 3 feet
<em><u>Solution:</u></em>
Given that, there 27 cubic feet in one cubic yard
Yard and feet are units of distance
1 Yard (yd) is equal to 3 feet (ft). To convert yards to feet, multiply the yard value by 3.
<em><u>The conversion factor for 1 yard to 1 feet is given as:</u></em>
Now find for 1 cubic yard . Cubic yard means yard raised to power 3
Therefore,
Thus one cubic yard is equal to 27 cubic feet
Therefore, there are 27 cubic feet in one cubic feet
Answer: 16590
Step-by-step explanation:
The formula we use to find the sample size is given by :-
, where p = prior estimate of population proportion.
= Critical z-value (Two- tailed)
E= Margin of error .
Let p be the population proportion of cyanobacteria.
Given : E = 0.01
Critical value for 99% confidence interval :
If Ian does not want to rely on previous knowledge , then we assume p=0.5 because the largest standard error is at p=0.5.
Now, the required sample size =
Required sample size = 16590
