A for ampere
K for kelvin
mol for mole
cd for candela
Answer: 3424.28
Step-by-step explanation:
Given data : 378, 361, 350, 375, 200, 391, 375, 368, 321
Number of data values = 9
Mean :

Variance = 

Variance = 
Step 1: Given
Step 2: Distributive Property
Step 3: Addition Property of Equality
Step 4: Division Property of Equality
Step-by-step explanation:
We need to match the reason with the correct step in the equation.
Equation:
Given:

Applying Distributive property a(b+c)=ab+ac

Now, Applying addition property of equality:
Adding +4x on both sides

Now, Applying Division property of Equality:
Divide both sides by 6:

So, Answer will be:
Step 1: Given
Step 2: Distributive Property
Step 3: Addition Property of Equality
Step 4: Division Property of Equality
