Answer:
10%
Step-by-step explanation:
The total population of students will be equal to the sum of both those who wore the silly hat and those who didn't hence
Total students= 74+666=740
Number of students who wore silly hat is given as 74 hence when expressed as a percentage of the total students' population we get that
percentage of the students wore a silly hat=
Therefore, 10% of students wore a silly hat last Tuesday
No its not polygons dont cross lines
Answer:
Step-by-step explanation:
Ok so to find constant of proportionality, you need to find K.
X would be gallons and y is cost.
To find k you need to do k=y/x
k=17.50/5
k=3.5
That's the first one. Now you need to make sure its <em>constant</em> with each one so keep going.
k=35/10
k=3.5
k=52.50/15
k=3.5
For all of those 3.5 was constant.
Because they are constant, that means the data in the graph is a proportion.
An example of an unproportional relationship would be if instead of 15 in the last column, it was 16.
k=52.50/16
k=3.28
That be different from the other 3.5's meaning its not proportional. But that's just an example.
