Answer:
942 ft²
Step-by-step explanation:
The diagram shows the area to be 3/4 of that of a circle of radius 20 ft. The area of a circle is given by ...
A = πr² = π(20 ft)² = 400π ft²
Then 3/4 of that area is ...
dog run = (3/4)(400π ft²) = 300π ft² ≈ 942.48 ft²
The area of the dog's run is about 942 ft².
Answer: 0.22
Step-by-step explanation:
We know that the best point estimate for the difference between two population mean is the difference between their sample means.
Given : For the 39 randomly selected upperclassmen, the sample mean was 0.12 and sample standard deviation was 0.42. For the 35 randomly selected underclassmen, the sample mean was 0.34 and the sample standard deviation was 0.87.
Let A denotes the population of upperclassmen and B denotes the population of underclassmen .


Then, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen will be :-

Hence, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen =0.22
Hello! 3.5m is equivalent to 350cm, which is also equivalent to 3,500mm. 100cm = 1 meter and 10mm = 1cm. 350/100 is 3.5. 3,500/10 is 350. 3,500 km does not belong, because that measurement would be way too big. The answer is 3,500km
