Answer:
The mean absolute deviation of this data is .
Step-by-step explanation:
The mean absolute deviation (MAD) of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.
The steps to find the MAD include:
- find the mean (average)
- find the difference between each data value and the mean
- take the absolute value of each difference
- find the mean (average) of these differences
To find the mean absolute deviation of this data you must
Step 1: Calculate the mean.
Step 2: Calculate the distance between each data point and the mean and take the absolute value of each difference
.
Step 3: Add the distances together.
Step 4: Divide the sum by the number of data points.
I think you divide 5/9 divided by 2/3.
5/9 divided by 2/3=4/3 simplified=2/3.
Just know I'm terrible at math so this could be like totally off the hook crazy and wrong.
Answer:
90km/h in m/s will be
90×1000m/3600s ( convert 1km/1h to 1000m/3600sec )
=> 25m/s
Answer:
The right solution is "0.15%".

Answer:
1/25
Step-by-step explanation:
The bag has:
- 2 yellow marbles
- 3 red marbles
- 5 blue marbles
- 10 total marbles
The probability of picking a yellow marble is 2/10=1/5.
So, the answer is (1/5)² = 1/25
