Life Expectancy for the lat 10 years and the next 10 years (AMERICA)

1.In words describe what the graph results mean for your country?
The graph means that the life expectancy for the countries population increases each year at a a average of 0.311.


2.How do life expectancy results relate the population growth of your country? (Were they what you expected?
It shows that the average time of life increases each year. This wasn't what I expected for the U.S. I thought the life expectancy would be lower because the American people have really bad habits of eating.

3.Can you explain any possible reasons for this relationship?
I think why the life expectancy is raising because the people are getting educated and knows what to do and what not.

Family Compound Interest Activity

For my blog post #4, I needed to talk to my parents about how much money the interest in the bank and the answer was that they didn't. My mom said that when I become older I should start interesting because of the fact that you never know when you need some money for an emergency. 

Personal CPI Percentages

The percentage in the chart increases by 1.1. Also the CPI is to small because of the increase in the price percentage each time and the only decrease is in the Ipad because the price is to big and from each generation it gets cheaper. The table of the student is not really right because you will buy for example 5 pop corns and 5 ice-creams but you will not buy 5 Ipads or 5 bikes. 

2 Real Life Situations on Calculating Percentages

1. This weekend when we went to a restaurant with my mom the bill was around 2000 dinars and my mom wanted to give a tip around 5 or 10 percent of that and she asked me to calculate how much it would be so I did. 5 percent of 2000 would be like 100 and 10 percent would be 200. So she decided that giving a tip of 5 percent was enough, which made her give a 100 dinar tip.

2. I had 20 euros and I want to change it into dinars at a currency exchange bank. But I decided I don't want to change the whole 20 euros!!! So I will only change 50 percent of it. It takes me a long time to figure out 50 percent of 20 euros, but at last I manage to so I just change 10 euros and get around 1000 dinars.

Fractions, Decimals and Percentages

How I feel on fractions, decimals and percentages at school?

When we were doing exercises on the board fractions were a bit confusing in the beginning but than I started to understand them really well. In decimals our teacher thought us a good and very interesting technique. It was like skipping two lines and drawing to half circles. He told us a story about it which makes me remember the way he does it. Percentages were much more easier than I expected at the beginning because I learned two or three easy ways to deal with them. It was really helpful for me.
