Final answer:
Double one hundred and fifty means to multiply 150 by 2. The calculation gives us the result of 300. Significance of figures is a different concept pertinent to measurements and precision, but not directly relevant to this multiplication.
Step-by-step explanation:
Double one hundred and fifty means to multiply the number 150 by two. To find this, we perform the multiplication: 150 × 2, which equals 300. Hence, double one hundred and fifty is 300.
This process involves a basic arithmetic operation known as multiplication, which is often used in various mathematical contexts. For instance, when understanding probabilities in a group of people where the chances of selection change with each pick, such as the chance being one in 150 for the first pick, and then one in 149 for the second pick, it's important to understand the implications of each numerical value. However, for our specific question, we are just dealing with the simple doubling of a number.
Understanding the significance of numbers is also relevant in mathematics, especially when considering significant figures in measurements. If you come across a measurement like 150 mm, one must consider if the zero is simply a placeholder or a significant figure. The context, such as the precision of the measuring device, plays a crucial role. However, in our case, where we are merely doubling the number, the significance of digits does not directly come into play.
