Answer:
1) 1.8
2) 1.7
Step-by-step explanation:
(for part A)
Mean: 3 + 5 + 6 + 3 + 2 + 2 + 1 + 0 + 0 + 4 + 7 + 4 + 5 + 5 + 6 = 53/15 = 3.5
3.5 - 3 = 0.5
3.5 - 5 = 1.5
3.5 - 6 = 2.5
3.5 - 3 = 0.5
3.5 - 2 = 1.5
3.5 - 2 = 1.5
3.5 - 1 = 2.5
3.5 - 0 = 3.5
3.5 - 0 = 3.5
3.5 - 4 = 0.5
3.5 - 7 = 3.5
3.5 - 4 = 0.5
3.5 - 5 = 1.5
3.5 - 5 = 1.5
3.5 - 6 = 2.5
mean absolute deviation: 0.5 + 1.5 + 2.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 0.5 + 3.5 + 0.5 + 1.5 + 1.5 + 2.5 = 27.5/15 = 1.8
(part B)
Mean: -3 + -2 + -1 + 0 + 1 + 2 + 3 = 0/7 = 0
0 - (-3) = 3
0 - (-2) = 2
0 - (-1) = 1
0 - 0 = 0
0 - 1 = 1
0 - 2 = 2
0 - 3 = 3
mean absolute deviation: 3 + 2 + 1 + 0 + 1 + 2 + 3 = 12/7 = 1.7
Answer:
Step-by-step explanation:
11 - 19 - 4 - (-8) =
11 - 19 - 4 + 8 =
- 23 + 19 =
- 4 <===
First find the answer to the equation
3 • 3/4 = 9/4
Reduce the fraction to a mixed number
9/4 = 2 1/4
Now determine which 2 whole numbers it is between
2 1/4 lies between 2 and 3
12 goes with 6 and 5 with 10
(6x^4+12x^2)+(-5x^2-10)
(6x^2)(x^2+2)+(-5)(x^2+2)
undistribute
(x^2+2)(6x^2-5)
Answer:
<h3>
</h3>
Step-by-step explanation:
Move 5x to left hand side and change it's sign
⇒
Move 3 to right hand side and change it's sign
⇒
Collect like terms
⇒
Subtract 3 from 21
⇒
Divide both sides of the equation by -6
⇒
Calculate
⇒
