Answer:
0,05
Step-by-step explanation:
1)First, Let’s find the mean of the data table
12 + 10 + 12 + 6 + 8 + 4 + 2 + 12 = 66
66 ÷ 8 = 8,25
2)12 - 8,25 = 3,75
10 - 8,25 = 1,25
12 - 8,25 = 3,75
6 - 8,25 = -1,75
8 - 8,25 = -0,75
4 - 8,25 = -3,75
2 - 8,25 = -5,75
12 - 8,25 = 3,75
3) 3,75 + 1,25 + 3,75 - 1,75 - 0,85 - 3,75 - 5,75 + 3,75 = 0,4
0,4 ÷ 8 = 0,05
Answer:
B
Step-by-step explanation:
let y = 5x - 3
rearrange making x the subject
add 3 to both sides
5x = y + 3 ( divide both sides by 5 )
x = 
change y back into terms of x, hence
(x) = 
→ B
Answer:
4 and 1/4 i think
Step-by-step explanation:
Turtle can go in any direction farthest to 4 block
hence Maximum Distance can be + 4 or - 4
Block representing farthest distance is x
Distance of block x from 112 would be
x - 112
x - 112 = ± 4
Taking mod both sides
=> | x - 112 | = | ± 4 |
=> | x - 112 | = 4
| x - 112 | = 4 is the equation which can be used to find the block numbers that represent the farthest distance that the turtle may be

Answer:
y -15 = -3(x +2)
Step-by-step explanation:
The slope will be ...
m = (y2 -y1)/(x2 -x1)
m = (-18 -15)/(9 -(-2)) = -33/11 = -3
Point-slope form is ...
y -y1 = m(x -x1) . . . . . line with slope m through point (x1, y1)
Using the first point, the equation is ...
y -15 = -3(x +2)
