Area of a circular play parachute:
A = 324 ft²
A = r² π
r² π = 324
r² = 324 : 3.14
r² = 103.1874
r = √103.1874
r = 10.157987 ≈ 10.2 ft
Andy will spend 12$ in wire.
We know this because he wants 25 ft of wire and there are 300 inches in 25ft
In the chart it says 150 inches is 6$ so if we multiply that by 2 we get the price for 300 inches which is 12$
Hope this helps :) comment if you need anymore help!
Answer:



Step-by-step explanation:
For this case we have a confidence interval given as a percent:

If we express this in terms of fraction we have this:

We know that the confidence interval for the true proportion is given by:

And thats equivalent to:

We can estimate the estimated proportion like this:

And the margin of error can be estimaed using the fact that the confidence interval is symmetrical

And then the confidence interval in the form desired is:

(D)We can prove THEOREMS with geometric rules........
