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.

<h3>Answer: -a > -b</h3>

Explanation:

Let's go over an example.

We'll have a = 1 and b = 7 which makes a < b true. Feel free to pick your own favorite pair of numbers such that b is larger than 'a'.

The corresponding opposites are: -a = -1 and -b = -7

The relationship flips because the opposites of each number are flipped. So instead of saying -a < -b, we have -a > -b

Sure enough, -1 > -7 is a true statement. Use a number line to see this. I recommend a vertical number line.

In short, going from a < b to -a > -b means we flip the signs of each term, and we flip the inequality sign as well.

Novay_Z [31]

Answer:

Step-by-step explanation:

x + 3•(+1) = 2•x + 4•(-1)

x + 3 = 2x - 4

-3 -3

x = 2x - 7

-2x -2x

- x = -7

÷(-1) ÷(-1)

x = 7

Image a coordinate plane with points plotted at ordered pairs Q(-4,4) R(2,4) S(5,-3) T(2,-3) and U (-4,-3) what is the area of t

pogonyaev

In counterclockwise order that's

R(2,4), Q(-4,4), U(-4,3), T(2,-3), S(5,-3)

That's a trapezoid, height 7 upper base 6, lower base 9, so average base 15/2 and area 7(15)/2 = 105/2 = 52.5.

Answer: 52.5

The shoelace theorem gives the answer without thinking. We write the list on top of itself shifted and add up the cross produces:

R(2,4), Q(-4,4), U(-4,-3), T(2,-3), S(5,-3)

Q(-4,4), U(-4,-3), T(2,-3), S(5,-3), R(2,4),

$A = \frac 1 2 | 2(4)-(4)(-4) + -4(-3)-(-4)(4) + -4(-3)- -3(2) + 2(-3)-(-3)(5) + 5(4)- -3(2)| = \frac{105}{2} \quad\checkmark$
