Questions: Sum the scores X and sum the scores Y and then multiply the sums.

Transcript text: Sum the scores $X$ and sum the scores $Y$ and then multiply the sums.

Solution

Solution Steps

Step 1: Calculate the Sum of Scores in $ X $

We have the scores in list $ X $ as follows: \[ X = [10, 20, 30] \] The sum of the scores in $ X $ is calculated as: \[ \Sigma X = 10 + 20 + 30 = 60 \]

Step 2: Calculate the Sum of Scores in $ Y $

The scores in list $ Y $ are given as: \[ Y = [5, 15, 25] \] The sum of the scores in $ Y $ is calculated as: \[ \Sigma Y = 5 + 15 + 25 = 45 \]

Step 3: Multiply the Sums

Now, we multiply the sums obtained from the previous steps: \[ \text{Result} = \Sigma X \times \Sigma Y = 60 \times 45 = 2700 \]

Final Answer

$\boxed{2700}$
