400(1.07)=428
28(5)=140
140+400= 540.

The correct answer is D. NURSING AIDES HAD FEWER PEOPLE IN 2002.
<span>Employment Projections
Job Number of People (2002) Projection (2012) Percent Change
Nursing Aides 1,375,000 1,718,000 25
Customer Service 1,894,000 2,354,000 24
(1,718,000 - 1,375,000) / 1,375,000 = 343,000 / 1,375,000 = 0.249 or 0.25 or 25%
(2,354,000 - 1,894,000) / 1,894,000 = 460,000 / 1,894,000 = 0.242 or 0.24 or 24%
The base number is the number of people in 2002. There is a higher percent change in number for nursing aides despite having lesser people added because its base number is lower than those in customer service. </span>
3.Slope: 10 Y int: 5
4. Slope: 5 Y int: 10
6.Slope: 1/3 Y int: 3.5
7.Slope: 4/3 Y int: -1
8.Slope: 2/-4 Y int: -1
The way you do this is the Y int is where the line crosses through the y-axis. Finding the slope is finding the rise over run (y/x). It's easy to find when you know how to.
Use 4. as an example. Start where at (-3,-5) or (-2,0). Each 'rise' up 5 and 'runs' one block over, giving you the slope of 5/1 or 5 simplified.
7 is harder, but start at (-3,-5). It 'rises' up 4, then 'runs' 3, also giving you the y int, as it crosses the axis. As the rise is 4 and run is 3, it creates the slope 4/3.

use Pythagorean Theorem to satisfy...a^2 + b^2 = c^2
200^2 + b^2 = 300^2
b^2 = 300^2 - 200^2
b^2 = 50000 (get square root of each)
b = 223.606 (rounded to the nearest tenth.... = 223.6
