Looks like one of my homework papers, back in the day. Calculus always gave me fits. If I can't count it, draw a picture of it, or get my hands on it, it's hopeless. :-(

4. (TCO B) A study of homeowners in the 5th congressional district in Maryland found that their annual household incomes are normally distributed with a mean of $41,182 and a standard deviation of $11,990 (based on data from Nielsen Media Research).
5. (TCO C) Until this year, the mean braking distance of a Nikton automobile moving at 60 mi per hour was 175 ft. Nikton engineers have developed what they consider a better braking system. They test the new brake system on a random sample of 81 cars and determine the sample mean braking distance. The results are the following
6. (TCO C) You are in charge of selling advertising for radio station WQAA. The fee you can set for airtime is directly related to the share of the listening market your station reaches. From time to time, you conduct surveys to determine WQAA’s share of the market. This month, when you contacted 200 randomly selected residential phone numbers, 12 respondents said they listen to WQAA
7. (TCO D) Persons living near a smelting plant have complained that the plant violates the city’s noise pollution code. The code states that to be in compliance, noise levels are only allowed to exceed 120 decibels less than 10% of the time. You monitor the noise levels at 150 randomly selected times and found that 11 were above 120 decibels. Does the sample data provide evidence to conclude that the plant is in compliance with the noise pollution code (witha = .05)? Use the hypothesis testing procedure outlined below.
8. (TCO D)Bill Smith is the Worthington Township manager. When citizens request a traffic light, the staff assesses the traffic flow at the requested intersection.

With the business of moving into a new home over the last month, it was finally good to get out a grab some pictures of the new neighborhood on an unseasonably warm fall evening.
Here are some shots of various buildings around the UIC campus. I found rickety fire-escape staircase and setup camp to grab this one.

It's powerful to still know how to use cross multiplication (here calculating dimensions for a video conversion). Thanks to my math teachers at Bedford Elementary School, Sudbrook Middle School, and Milford Mill High for showing me the power of math... even wacky Blooma Friedman, my 10th grade chemistry teacher, who insisted we learn how to use a slide rule (sorry Blooma, I did forget that).

The crow probably feels a little bit left out but thats ok because crows are the best.
We had to do a project as part of the summer scholl I attened in Beijing. I ended up in a group doing a mathematical model of coca production in Peru. This is what the blackboard looked like when we finally finished designing the thing.
We think that

The core of economy is finance.
The foundation of finance is Mathematics, etc.

Imagine letting your child play with sharp map pins AND higher math--all by themselves!
That's what I did when I was a kid--this isn't my set but it is the same one that I had. I struggled trying to keep the map pins in the big wheels, and never had the patience to make the more complicated diagrams.
I found this set, missing its four pens and two plastic wheels, but with the map pins (under the blue storage case) and the original booklet of instructions.
BTW, this is the 1967 version--Kenner introduced the toy in 1966.
