Answer: The distribution of the data set is positively skewed.
<u>Explanation: </u>
In order to see whether the given data set is symmetric, positively skewed or negatively skewed, we will find the mean, median and mode of the given data set.
For symmetric distribution,
For positively skewed distribution,
For negatively skewed distribution,
The mean of the given data set is given below:
Now, the Median is:
To find the median we need to sort the data in ascending order as:
The mode is the most frequently occurring observation. Therefore the mode is:
Since the , therefore the distribution of the given data set is positively skewed.
Answer:
Radius, r = 61 cm
Step-by-step explanation:
According to the attached figure, we have,
Length of chord, AB = 22 cm
Such that, AP = PB = 11 cm
OP = 60 cm
It is required to find the radius of the circle. We know that radius of a circle is perpendicular to chord. So, APO forms a right angled triangle. Using Pythagoras theorem to find the radius of circle. Let it is r. So,
So, the radius of the circle is 61 cm.
