In the ratio of miles traveled, Mr. Storey and Mrs. Storey's journey is represented as mr: mrs = 3: 1. The total of these ratio units equals 4 (3+1), which means each unit corresponds to 3200 divided by 4, resulting in 800 miles. Mr. Storey drove 3 multiplied by 800, equating to 2400 miles, while Mrs. Storey drove 1 multiplied by 800, totaling 800 miles.
Answer:
In this case, the method of sampling employed by the poll
Explanation:
Convenience sampling, often referred to as grab, opportunity, or accidental sampling, is a non-probability sampling technique where the sample is collected from the part of the population that is easily accessible. This technique proves to be particularly useful for preliminary investigations.
This type of sampling makes selections based on ease of access, willingness of individuals to participate, and availability at specific times.
Consequently, this approach can lead to biased results and may not yield the expected outcomes.
In this scenario, we have the complex number:
1 + i
The corresponding pair is represented as:
root (2) * (cos (pi / 4) + i * sin (pi / 4))
By rewriting this, we have:
root (2) * (root (2) / 2 + i * (root (2) / 2))
(2/2 + i * (2/2))
(1 + i)
Answer:
option A shows a pair representing the same complex number
