Question

Accepted Answer

1. **For creating a histogram**:
   - **Explanation**:
     - **Step1: Determine data - range and bins**
       - First, we need to collect data on the number of jobs people have had in their life. Let's assume we have a set of values like $1,2,3,4,5,\cdots$. Decide on the number of bins. For example, if the maximum number of jobs is 10, we could have bins like $0 - 2$, $3 - 5$, $6 - 8$, $9 - 10$.
     - **Step2: Count data in each bin**
       - Go through the data set and count how many values fall into each bin. For instance, if our data set is $\{1,3,4,6,8\}$, the first bin ($0 - 2$) has 1 value, the second bin ($3 - 5$) has 2 values, the third bin ($6 - 8$) has 2 values, and the fourth bin ($9 - 10$) has 0 values.
     - **Step3: Draw the histogram**
       - On the x - axis, label the bins, and on the y - axis, label the frequency (the number of data points in each bin). Draw bars for each bin with heights corresponding to the frequency of that bin.
   - **Answer**: A histogram with appropriate bins and frequencies based on the collected data.
2. **For reflecting a shape over the y - axis**:
   - **Explanation**:
     - **Step1: Recall the reflection rule**
       - The rule for reflecting a point $(x,y)$ over the y - axis is $(-x,y)$.
     - **Step2: Apply the rule to each point**
       - Let's say we have a shape with points $(1,2)$, $(3,4)$, $(5,6)$. After reflection over the y - axis, the new points are $(-1,2)$, $(-3,4)$, $(-5,6)$.
   - **Answer**: The new set of coordinate points obtained by applying the $(-x,y)$ rule to each original point.
3. **For filling out coding blocks**:
   - Since no specific coding blocks or language is given, an example in a general block - based coding like Scratch could be: If the block is a "move" block, we could fill it with "move 10 steps forward".
   - **Answer**: An appropriate instruction filled in the given coding blocks based on the nature of the blocks.
4. **For drawing the top - view of a 3D object**:
   - **Explanation**:
     - **Step1: Visualize the top - down perspective**
       - Imagine looking at the 3D object from directly above. Identify the outlines and shapes that would be visible. For example, if the 3D object is a rectangular prism with a triangular prism on top, from the top - view, we might see a rectangle (from the base of the rectangular prism) and a triangle (from the top of the triangular prism).
     - **Step2: Draw the top - view**
       - Use a ruler (if drawing by hand) to draw the shapes accurately. If using a digital tool, use the appropriate drawing functions to create the top - view.
   - **Answer**: A 2D drawing representing the top - view of the given 3D object.
5. **For finding the angle measure**:
   - **Explanation**:
     - **Step1: Identify the scale on the protractor**
       - The protractor has two sets of numbers, an inner and an outer scale. Determine which scale to use based on the orientation of the angle.
     - **Step2: Align the protractor**
       - Place the center of the protractor on the vertex of the angle and align one side of the angle with the 0 - degree mark on the protractor.
     - **Step3: Read the angle measure**
       - Look at the point where the other side of the angle intersects the protractor and read the corresponding degree value.
   - **Answer**: The degree value of the angle as read from the protractor.
