Explanation:

First Question (Picture Enlargement)

Step1: Find the scale factor

To enlarge by 75%, the scale factor is \(1 + 0.75=1.75\) (or \(\frac{7}{4}\)).

Step2: Calculate new length (8 inches side)

New length \(= 8\times1.75 = 14\) inches.

Step3: Calculate new width (12 inches side)

New width \(= 12\times1.75 = 21\) inches.

Step1: Count total games

Total games \(= 8\) (from Game 1 to Game 8).

Step2: Count win games

Win games: Game 1, 3, 4, 5, 7, 8 (that's 6 wins? Wait, wait: Game 1 (Win), Game 2 (Loss), Game 3 (Win), Game 4 (Win), Game 5 (Win), Game 6 (Loss), Game 7 (Win), Game 8 (Win). So wins: 1,3,4,5,7,8 – that's 6? Wait no, let's count again: Game 1: Win (1), Game 2: Loss (0), Game 3: Win (2), Game 4: Win (3), Game 5: Win (4), Game 6: Loss (0), Game 7: Win (5), Game 8: Win (6). Wait, but wait the table: Game 1 (Win), Game 2 (Loss), Game 3 (Win), Game 4 (Win), Game 5 (Win), Game 6 (loss), Game 7 (Win), Game 8 (Win). So number of wins: 6? Wait no, wait the original table: let's list them:

1. Game 1: Win
2. Game 2: Loss
3. Game 3: Win
4. Game 4: Win
5. Game 5: Win
6. Game 6: loss
7. Game 7: Win
8. Game 8: Win

So wins: 1,3,4,5,7,8 – that's 6? Wait, no: 1 (Win), 3 (Win), 4 (Win), 5 (Win), 7 (Win), 8 (Win) – that's 6 wins? Wait, but 1+1 (Game3) +1 (Game4)+1 (Game5)+1 (Game7)+1 (Game8) = 6? Wait, Game 1: 1, Game3:2, Game4:3, Game5:4, Game7:5, Game8:6. Yes, 6 wins. Wait, but total games 8. Wait, but wait the table: Game 1 (Win), Game 2 (Loss), Game 3 (Win), Game 4 (Win), Game 5 (Win), Game 6 (loss), Game 7 (Win), Game 8 (Win). So wins: 6? Wait, no, wait: Game 1 (Win), Game3 (Win), Game4 (Win), Game5 (Win), Game7 (Win), Game8 (Win) – that's 6? Wait, but 1 (Game1) + 1 (Game3) +1 (Game4)+1 (Game5)+1 (Game7)+1 (Game8) = 6. Losses: Game2 and Game6 – 2 losses. So total games 8. Then win percentage \(=\frac{\text{Wins}}{\text{Total}}\times100=\frac{6}{8}\times100 = 75\%\)? Wait, no, \(\frac{6}{8}=0.75\), so 75%? But option A is 75%, B is 60%. Wait, did I count wrong? Wait let's check again:

Game 1: Win (1)

Game 2: Loss (0)

Game 3: Win (2)

Game 4: Win (3)

Game 5: Win (4)

Game 6: loss (0)

Game 7: Win (5)

Game 8: Win (6)

Ah! Wait, Game 7 and Game 8: that's two more. So total wins: 6? Wait, 1 (Game1) +1 (Game3)+1 (Game4)+1 (Game5)+1 (Game7)+1 (Game8) = 6. Total games 8. So \(\frac{6}{8}=0.75 = 75\%\). Wait, but the options have A as 75%. But wait, maybe I miscounted. Wait, Game 1: Win, Game3: Win, Game4: Win, Game5: Win, Game7: Win, Game8: Win – that's 6 wins. Losses: Game2 and Game6 – 2. So 6 wins out of 8. 6/8 = 0.75 = 75%. So answer is A? Wait, but let's check again. Wait the table:

Game 1: Win

Game 2: Loss

Game 3: Win

Game 4: Win

Game 5: Win

Game 6: loss

Game 7: Win

Game 8: Win

So wins: 1,3,4,5,7,8 – 6 wins. Total games: 8. So 6/8 = 0.75 = 75%. So:

Step1: Count total games

Total games \(n = 8\).

Step2: Count win games

Win games \(w = 6\) (Wait, no: wait Game 1 (Win), Game3 (Win), Game4 (Win), Game5 (Win), Game7 (Win), Game8 (Win) – that's 6? Wait, no, Game 1:1, Game3:2, Game4:3, Game5:4, Game7:5, Game8:6. Yes, 6. Wait, but maybe I made a mistake. Wait, Game 1: Win, Game3: Win, Game4: Win, Game5: Win, Game7: Win, Game8: Win – 6 wins. Losses: 2. So 6/8 = 75%. So:

Step3: Calculate win percentage

Win percentage \(=\frac{w}{n}\times100=\frac{6}{8}\times100 = 75\%\). Wait, but 6 divided by 8 is 0.75, times 100 is 75%. So:

Answer:

D. 14 in by 21 in
