Answer:
±12
15.8% or 13.5 %
Step-by-step explanation:
Most absolute error would be when actual count was 77 or 89 but number counted was 89 or 77 respectively.
absolute error= 89-77 or 77-89
Percent error= 12/77 × 100 or 12/89× 100
Answer:
B. 1
Step-by-step explanation:
The slope is calculated by taking the difference in the y-coordinates of two points and dividing that by the difference in the x-coordinates of those two points.
Here, we have (6, -12) and (15, -3).
The difference in the y-coordinates is:
15 - 6 = 9
The difference in the x-coordinates is:
-3 - (-12) = -3 + 12 = 9
Divide 9 by 9:
9/9 = 1
The slope is thus 1, and the answer is B.
7x-2=-23 add 2 to both sides to get 7x by itself
7x=-23+2 now add the right side
7x=-21 now divide both sides by 7
x=-21/7
x=-3
Multiply then combine similar variables
. The answer is y6
