https://padlet.com/kathmatics/7329a4qkiph Directions: I want your group to estimate the percentage of BLACK cars parked ON CAMPUS. I want your group to post 2 things on this page: 1) A description of HOW you made your estimate. 2) What your estimate of the percentage of black cars parked on campus is. en-us 2017-06-12 17:29:23 UTC 2023-05-20 15:35:13 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Carfront.png https://padlet.com/kathmatics/7329a4qkiph/wish/176154384 According to Wikipedia, 19% of cars in North America are painted black.  We sampled  73 cars in the parking lot, and 17 were painted black (23%).

Final answer: 21%]]> 2017-06-12 19:43:59 UTC https://padlet.com/kathmatics/7329a4qkiph/wish/176154384 https://padlet.com/kathmatics/7329a4qkiph/wish/176154390 1.We narrowed it down to one small parking lot in front of the mub building.  

2.  A total of 30 cars were parked in the parking lot and 8 of them were black. 

8/30= 26.666666667%

There is a small percentage with colored cars, from typical experiences and what we see in the CCSF parking lot. Then we just estimated that about 40% are black, 40% white, and 20% colored.

We did this with two different areas in the parking lot around the MUB building. From that, we calculated two percentages and found the average of the two.

The total cars counted was 162 and the total number of black cars counted was 27.

2) 16.7%  of the cars were black.

To give the estimate of how many Black cars are here in the CCSF parking lots, our estimation would be around 35%-40%.

Assuming that all areas of North America are uniformly distributed, then we can say that around 19% of all cars parked in the CCSF parking lot are painted black.]]> 2017-06-12 19:45:06 UTC https://padlet.com/kathmatics/7329a4qkiph/wish/176154461 cynthia_g_taylor https://padlet.com/kathmatics/7329a4qkiph/wish/176154623 1. We counted the black cars in three rows in the student parking lot. We then calculated the percentage of black cars in each of those rows and averaged those three numbers.

2. We determined that approximately 29% of cars on campus are black.]]> 2017-06-12 19:46:43 UTC https://padlet.com/kathmatics/7329a4qkiph/wish/176154623 https://padlet.com/kathmatics/7329a4qkiph/wish/176154682 We calculated the number of parking spaces on campus and counted the number of visible black cars to get roughly 20% of the cars on campus being black.
