a motorist drives 80km at an average speed of 63km/h.which average is this:mean median or mode
mean
No problem, I can help you out!
In this case, the given information is the distance traveled (80km) and the average speed (63km/h).
To find the mean average of speed, we need to divide the total distance by the time taken. We can use the formula:
mean = total distance / total time
We don't have the time taken, but we can calculate it using:
time = distance / speed
So, time taken = distance / speed = 80km / 63km/h = 1.27 hours
Now we can find the mean average using:
mean = total distance / total time = 80km / 1.27 hours = 63.0 km/h
Therefore, the average given is the mean.
Well, if the motorist drove 80km at an average speed of 63km/h, we aren't talking about mean or median.
The mean is calculated by adding up all the values and then dividing by the number of values. In this case, we don't have multiple values for speed, just one average speed.
The median, on the other hand, is the middle value when the data is arranged in order. But here, we don't have a set of speeds to arrange.
The mode is the most frequently occurring value. But again, we only have one average speed here.
So, in this case, it's none of the above. The average speed of 63km/h is simply the average speed.
A motorist drives 80km as an average speed of 63km/h.which average is this mean,median and mode
I don't know
To identify which average (mean, median, or mode) is being referred to in this scenario, let's first understand what each of these terms represents:
1. Mean: The mean is calculated by summing up all the values in a dataset and dividing it by the total number of values. It represents the central tendency of the data.
2. Median: The median represents the middle value in an ordered dataset. If the dataset has an odd number of values, the median is the exact middle value. If the dataset has an even number of values, the median is the average of the two middle values.
3. Mode: The mode is the value (or values) that appear most frequently in a dataset.
Now, let's apply this knowledge to the scenario provided. In the given information, a motorist drives 80 km at an average speed of 63 km/h.
This scenario does not provide a dataset but rather a single value (average speed) for a given distance. Since we only have a single value and no other data points, there is no need to calculate any of the three averages mentioned.
Therefore, in this particular scenario, none of the averages (mean, median, or mode) are applicable.
