Answer:
A = 3
B = 1
C = 2
D = 10
E = 2
F = Not listed
G = 1
Step-by-step explanation:
Answer:
1. y = -2/3x + 2
2. y = 2/4x + -3
3. y = 1x -1
To find the solution we will first find the difference between each number and mean, and then substitute the value in the formula of standard deviation.
The standard deviation is 8.4477 and the variance is 71.40.
Given to us
- Test scores of Adimas = (76, 87, 65, 88, 67, 84, 77, 82, 91, 85, 90)
- Mean = 81
difference between each number and mean,
= 25 + 36 + 256 + 49 + 196 + 9 + 16 + 1 + 100 +16 + 81
= 785
Variance =
= 71.40
Hence, the standard deviation is 8.4477 and the variance is 71.40.
