Answer:
The expression for the given value of the variable d=75 is, 135
Step-by-step explanation:
Given the expression:
....[1]
We have to find the value for the given expression when d = 75
Substitute the value of d in [1] we have
⇒
⇒
Simplify:
⇒
Therefore, the expression for the given value of the variable d=75 is, 135
Answer:
represent the random sample selected
represent the number of pots that were bare ground (no vegetation
And replacing we got:
So then the sample proportion of bare ground spots is 0.792 for this sample
Step-by-step explanation:
We have the following info given from the problem:
represent the random sample selected
represent the number of pots that were bare ground (no vegetation)
And for this case if we want to find the sample proportion of bare ground spots we can use this formula:
And replacing we got:
So then the sample proportion of bare ground spots is 0.792 for this sample
