A visual example of this is one my mother showed me. She drew a circle and laid out a piece of yarn around it so that it imitated the perfect shape of the circle. She laid out another piece that was as long as the circle's radius. She wrapped the longer piece around the shorter one, and I saw that it could wrap around it three times and still have at least 0.14 units left. I'm not sure if this helps, but the circumference of this circle is 18.84 cm ^2. I hope I answered your question.
3^2 + 4^2 = 5^2
65/5=13
3x13 =39
4 x 13= 42
Answer:
66
Step-by-step explanation:
105+420=525 (Total Money)
7x3.25=22.75 (Cost of all bracelets)
8x11.74=93.92 (Cost of all necklaces)
93.92+22.75=116.67 (Cost of all Christmas presents)
525-116.67=408.33 (Total money - Cost of all Christmas presents)
408.33/6.15=66.39... (Amount of necklaces)
since in real life you can only buy a whole number of things, you would round down 66.39 to 66. I hope this helped!
Answer: Biased sample
Step-by-step explanation:
This is a biased sample because only students with strong opinions are likely going to volunteer or show interest in representing the school at the board meeting. This sample is a voluntary type sample, and at such the conclusion is not valid. This sample is biased because a group or population of students have a higher or lower sampling probability.
