Applying arithmetic operators Assume that \( x=7, y=20 \), and \( z=2 \). 4. Given the following lines of code, what is the output of the code? \[ =0 \] \( c=x-z \) \( c=c+1 \) print (c) \( \quad \begin{array}{r}\text { a. } 1 \\ \text { b. } 5 \\ \text { (c. } 6 \\ \text { 5. What is the value of } a \text { ? } \\ \text { a }=3.5 \text { - } 1.5 \\ \text { a. } 2 \\ \text { b. } 2.0 \\ \text { c. } 2.5\end{array} \)

Let's evaluate each problem step by step. --- **4. Given the following lines of code, what is the output of the code?** ```python x = 7 z = 2 c = x - z c = c + 1 print(c) ``` **Step-by-Step Evaluation:** 1. **Initialize Variables:** - `x = 7` - `z = 2` 2. **First Operation:** - `c = x - z` - `c = 7 - 2` - `c = 5` 3. **Second Operation:** - `c = c + 1` - `c = 5 + 1` - `c = 6` 4. **Print Statement:** - `print(c)` will output `6` **Answer Choices:** - a. 1 - b. 5 - c. 6 **Correct Answer:** **c. 6** --- **5. What is the value of \( a \)?** \[ a = 3.5 - 1.5 \] **Calculation:** - \( a = 3.5 - 1.5 = 2.0 \) **Answer Choices:** - a. 2 - b. 2.0 - c. 2.5 **Correct Answer:** **b. 2.0** --- **Summary of Answers:** - **Problem 4:** c. 6 - **Problem 5:** b. 2.0
