Answer:
it does represent the total area
Step-by-step explanation:
To do this, you have to know the original perimeter of this park (490 yds) and the area (14,500 yds squared)
A park with the same perimeter (490 yds) but smaller area (9,750 yds squared) is 195ydsx50yds
Answer: 20
Step-by-step explanation:
Formula to find the sample size :
Given : Significance level :
Critical value :
Margin of error :
Standard deviation:
Then, we have
Hence, the minimum sample size must be 20.
Answer:
Step-by-step explanation:
Answer: FALSE
You get y = 2x +4 so the slope is 2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is -1/2.
