Percent decrease=decrease/original times 100
decrease=23.5-21.2=2.3
original=23.5
percent decrease=2.3/23.5 times 100=0.0978 times 100=9.8%
B is answer
The formula of a slope:
We have the points (15, 130) amd (1, 160). Substitute:
Find the difference between each term, (e.g 3,5,7,9 —> the difference is 2 so it would be 2n) and then you minus that number from the first term (3-2=1) so therefore the nth term for that sequence would be 2n + 1
<h3>
Answer: Choice D. (0, 13) and (10, 0)</h3>
Reason:
If you were to draw a line through the points mentioned in choice A, the line wouldn't be close to the points since (4,15) isn't close to the points. The same goes for (10,7). So we can rule out choice A. Choices B and C are similar stories.
Choice D on the other hand has its line fairly close to all of the points.
Length of AB: 8 - - 6 = 14
Mid point at half length: 14/2 =7
