Answers

Answer:

Okay so for A the thing that is wrong with this experiment is that Cindy has done quite a few things incorrectly. Firstly what her experiment was about. Being healthy is a good thing but then turning around and doing the exact opposite for a week can damage your body. Secondly, Running 4 miles after school is good but then for the next week she sits and watches tv for 3 hours. It doesn't make sense on how she measured her experiment. Cindy should have recorded the times when she ran four miles and then used the same time to watch Tv for the next week.

We can fix this experiment by maybe taking out the hot Cheetos from it as that's just not healthy. Secondly we can have Cindy record how many minutes/hours she ran in the 4 miles and use those same times to watch Tv so that it's even.

Explanation:

For part B firstly it's just not possible to predict the weather with your feet. Secondly your grandpa could easily lie and tell you their hurting or they could just always be sore. Lastly, His feet could be not sore and it still rains.

We can fix this experiment by may be doing something more realistic. But to stay on this instead of calling him you should maybe stay over so that in the morning you can tell whether or not his feet are sore then record for the rest of the day to see if it rains or not. If their not sore and it rains then we know he can't predict weather with his feet the same goes for if they were sore and didn't rain.

Answers

Low precision and low accuracy best describe the archer's results. So the correct option is A.

Who is an archer?

Archery is a sport that involves firing arrows with a bow at inanimate objects or animals during a hunt.

With the exception of Australia, the bow has been a primary tool of combat and the hunt from prehistoric times.

Ancient Egyptians and Greeks also engaged in recreational archery in addition to military archery, an example of the latter being the contest in which Odysseus triumphed and gained Penelope's hand.

Large portions of Asia were ruled by horse-mounted archers such as the Huns, Seljuq Turks, Mongols, and others for around 15 centuries beginning in the first century CE.

During the Hundred Years' War (1337–1453), English longbowmen earned magnificent military successes, while the crossbow gained popularity throughout continental Europe, particularly in Switzerland, some regions of Germany, France, and the Low Countries.

Therefore the correct option is A.
