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
answer is cpctc
corresponding parts of congruent triangles are congruent (cpctc)
Answer:
C
Step-by-step explanation:
First, factor the original expression:
As we can see, D is the same as above. Eliminate D.
Go through each of the answer choices.
A:
This is equivalent to what we factored. Eliminate A.
B:
This is again equivalent to what we factored. Eliminate B.
C:
This cannot be simplified and it is not equivalent to what we have previously. C is not the equivalent expression.
