My pictures are the one's that we learnt today.

Aicelle's Graphing Post

There are 5 different graphs that can be represented.
Graphs: Bar Graphs, Line Graphs, Double Bar Graphs, Circle Graphs, and Pictographs.

Bar Graphs

Advantage - Good for comparing across categories.

Disadvantage - You can only use it with several data.

Line Graphs

Advantage - Good for showing changes over time.

Disadvantage - You can only use it when it changes over time.

Double Bar Graphs

Advantage - Good for comparing 2 sets of data across categories.

Disadvantage - You might get mixed up.

Circle Graphs

Advantage - Good for comparing to the whole using percents.

Disadvantage - You will not know the exact number and it also takes long to do.

Pictographs

Advantage - Good for comparing data that can be counted easily.

Disadvantage - You will not know if it is a half or not.

3 ways you can misrepresent a graph.

Break in the y-axis.

Make one picture bigger than the other.

Colour one bar different from the others.

The 2 graphs that will show it more accurately are line graphs and a bar graph.

If I was selling Pizza Subs I will continue because a lot of people are buying every week.

I would choose a Line Graph because it shows that every month, a lot more people are choosing healthy food.

Aicelle's Proportion Post

What is ratio?

A ratio shows the relationship between 2 quantities.
Ex. 13:43

What is rate?

A rate compares two quantities measured in different units.
Ex. 40m/h or $0.70/100g

What is proportion?

A proportion shows an equation which state that 2 ratios or fractions are equal.
Ex. 4/8=48/96

4x12=48 8x12=96

1.) 5 hours to travel 360 miles is about 72mph

2.) As a playgroup worker, if I increase the amount of apple juice I am serving at the playgroup from 25 ml to 100 ml, how much should I increase the orange juice to, to keep the quantities in the same proportion? The orange juice is 50 ml to start with. 200 ml

25/100 = 50/x

25x4=100 50x4=200

What are the three ways you can prove that equivalent ratio statements are true?

3/4 = 12/16 TRUE

4/9 = 16/32 FALSE

Proportion problem image

1. Does this seem fair? No.
2. With what you know about proportion look and read what is in the image above. Does it seem just and fair? Why have you made this choice? No, it does not seem fair because the homeless person had 15 years in prison for stealing $100 to have a place to sleep in, but surrendered the next day because he felt guilty. While the CEO of the Ex-Mortgage took away $3 billion and only went to prison for 3 years.
   
3. What would you have done if you were the judge? I would have given him a year or 10 months in prison because he surrendered voluntarily also he only took $100. The CEO, I would've given him 30 years in prison because he took away the $3 billion from the company.
