To decode Jameela's shopping list, we need to convert the binary numbers into decimal.
1. **Binary "101"**:
- This converts to decimal as follows:
- \( 1 \times 2^2 + 0 \times 2^1 + 1 \times 2^0 = 4 + 0 + 1 = 5 \)
- So, she needs **5 notebooks**.
2. **Binary "1111"**:
- This converts to decimal as follows:
- \( 1 \times 2^3 + 1 \times 2^2 + 1 \times 2^1 + 1 \times 2^0 = 8 + 4 + 2 + 1 = 15 \)
- So, she needs **15 apples**.
Therefore, Jameela really needs **five notebooks and 15 apples**.
The correct response is:
**five notebooks and 15 apples**.

The term **"bit"** refers to a single binary digit, which can either be 0 or 1. The representation "110010" consists of multiple bits (specifically, 6 bits in this case).
When referring to "110010" as a whole, it is more accurate to call it a **binary number** because it represents a complete numerical value in the binary numeral system.
In summary:
- **"Bit"** refers to a single 0 or 1.
- **"Binary number"** refers to a complete sequence of bits representing a numerical value.
Thus, while "110010" is made up of bits, it is more appropriately identified as a binary number.

The letter "J" can be represented in binary using the ASCII encoding system. In ASCII, the letter "J" has the decimal value 74.
To convert 74 to binary:
1. Start dividing the number by 2 and noting the remainders.
2. 74 divided by 2 equals 37 with a remainder of 0.
3. 37 divided by 2 equals 18 with a remainder of 1.
4. 18 divided by 2 equals 9 with a remainder of 0.
5. 9 divided by 2 equals 4 with a remainder of 1.
6. 4 divided by 2 equals 2 with a remainder of 0.
7. 2 divided by 2 equals 1 with a remainder of 0.
8. 1 divided by 2 equals 0 with a remainder of 1.
Reading the remainders from bottom to top, 74 in binary is represented as **1001010**.
This binary representation consists of **7 bits**.
So, it takes **7 individual bits** to write the letter "J" in binary.
To convert 74 to binary:
1. Start dividing the number by 2 and noting the remainders.
2. 74 divided by 2 equals 37 with a remainder of 0.
3. 37 divided by 2 equals 18 with a remainder of 1.
4. 18 divided by 2 equals 9 with a remainder of 0.
5. 9 divided by 2 equals 4 with a remainder of 1.
6. 4 divided by 2 equals 2 with a remainder of 0.
7. 2 divided by 2 equals 1 with a remainder of 0.
8. 1 divided by 2 equals 0 with a remainder of 1.
Reading the remainders from bottom to top, 74 in binary is represented as **1001010**.
This binary representation consists of **7 bits**.
So, it takes **7 individual bits** to write the letter "J" in binary.

The number 35,674 is an example of a **long** integer.
Here's a brief explanation of the terms in the given options:
- **Long**: Typically used to refer to an integer type that can hold larger values than a standard integer. It generally is chosen for integer values that exceed the range of a typical 32-bit integer.
- **Float**: Refers to a floating-point number, which includes decimal values (e.g., 35,674.5).
- **Short**: Refers to a smaller integer type, which usually has a limited range compared to a standard or long integer.
- **Boolean**: Refers to a value that can be either true or false.
Since 35,674 is a whole number, it fits best as a **long integer**.
So, the correct response is:
**long**.

Code that has been converted from binary into letters and symbols that computers can "read" is typically referred to as **source code** or **human-readable code**. This can also include formats like plaintext, which represent data in a way that is more understandable to programmers and users.
In a broader sense, you might also encounter the term **compiled code**, which refers to code that has been translated from a high-level programming language (like C++ or Java) into machine code that a computer's processor can execute, but this is a step beyond just converting binary into letters and symbols.
So, the best general term to describe code converted from binary is **source code** or simply **code** that is human-readable.
