Concept: Caclulating Standard Variables
- We have a five number summary which is more than enough information to calculate our mean.
- The mean is the sum of all the numbers divided by the nth number of numbers.
- Note that we can only find a rough estimation not the EXACT value
- We do (min +max + 2(Q1+median+Q3))/8
- Now let's plug in our values!
- (0+85.3+2(8.4+17.4+30.9))/8
- Which gives us option B

Answer:
2(xy + 2)(x + 1) (C)
Step-by-step explanation:
2x^2y + 2xy + 4x + 4
= 2xy(x + 1) + 4(x + 1)
= (2xy + 4)(x + 1)
= 2(xy + 2)(x + 1)
