So just divide 100 by 25 which equals 4 then divide 120 by 30 which also equals to 4 and if the rest equal 4 then its proportional (1)
And then same for 2 and 3 just divided the bottom by the top and if they all get the same answer they are proportion and if one is not the same then it’s not
For the grids if the dots are line diagonally straight and it starts at the 0 then it’s proportional if not then it’s not
Hope this helps :)
Here are the numbers of times 11 people ate out last month. 4, 6, 6, 5, 7, 4, 4, 5, 4, 5, 5 Find the modes of this data set. If

Answer:
4, 5
Step-by-step explanation:
put in order form least to greatest
4,4,4,4,5,5,5,5,6,6,7
whichever number occurs the most is the mode, if two numbers occur the same amount of times, they are bith the mode.

You have 4/11 probability of pulling a blue marble. A 5/11 probability of pulling a black marble. A 2/11 probability of pulling a red marble.
First, we have to find the length of each side of triangle. Equilateral triangle means 3 sides r in same length, so each side will be 21 ÷ 3 = 7
Now we need to calculate the height of the triangle. We can do this by Pythagoras theorem
Let the height be h
(7/2)^2 + x^2 = 7^2
The area should be 6.0621778265
Or u can say 6.06 corrected to 3 sig fig
