4.81
5.This would affect the final answers because then each section could have more or less students.
6.No, because if you don't know how many students are in one category then there is a very big array of different numbers that could be in that one category.
Page 2:
1.Less, because just by looking at the yellow section you can see that it does not cover at least half of the chart.
2. 48%
3.550
4.44
5.264
6.77
7.66
8.No because if you know the value of one category then you can't determine the other percentages because they could be anything.

1.42%
2.300
3.45
4.27
5.18
6.7 times more people said popcorn is their favorite movie snack than hot dogs.
7. I added the percentages I know and then subtracted that number from 100 to get the percentage of popcorn.
Step-by-step explanation:
I included the explanation for answers that required in the answer and this took a long time to complete. I hope I could help!
Given that amount of first acid solution = 4 liters
Let concentration of the first acid solution = x
then effective amount of first solution = 4x
Given that amount of second acid solution = 10 liters
Givn that concentration of the second acid solution = 40% = 0.4
then effective amount of second solution = 0.4(10)
Then amount of resulting acid solution = (4+10) liters
Givn that concentration of the resulting acid solution = 30% = 0.3
then effective amount of resulting solution = 0.3(4+10)
Combining all those results gives equation
4x +0.4(10) = 0.3(4+10)
4x +4 = 0.3(14)
4x +4 = 4.2
4x = 0.2
x=0.05
Hence final answer is 0.05 or you can say 5%.
Answer:
Division Equation: 5,640 ÷ 15 = y
Multiplication Equation: 15 x y = 5,640
Answer:
y = |x + 2|
Step-by-step explanation:
given the straight shape, it must be a linear function, but the "bend" in it indicates that an absolute value is being used.
So to start we can say: y = |x|
But that's not sufficient, as it would show that bend being at 0, 0. Instead, we need to translate it two units to the left, giving us:
y = |x + 2|
