Complete question :
X: 3, 4, 5, 6
f(x): .25, .55, .15, .05
Answer:
0.60
Step-by-step explanation:
Given the data:
Variance (s) :
Σx²*f(x) - E(x)²:
E(x) = (3*0.25) + (4*0.55)+(5*0.15)+(6*0.05) = 4
Σx²*f(x) - E(x)²: [(3^2 * 0.25)+(4^2 * 0.55)+(5^2 * 0.15)+(6^2 * 0.05)] - 4²
16.6 - 16 = 0.6
A. No x value can have multiple different outputs.
D. The change in y between x values is 4 but the function when x is 0 is -2
The answer to the question
Answer:
$9261
$1261
Step-by-step explanation:
Principal: $8000
Interest rate: 5% PA compounded annually
Time: 3 years
- Sum = $8000*(1.05)³ = $9261
- Interest = $9261 - $8000 = $1261
