Area of the yard is 40 .20 = 800sq ft
time taken = 25 mins
time taken to mow 1sq ft = 25/800 mins
time taken to mow 40 .30 =1200sq ft = ( 25 .1200)/800 = 371/2 mins
thus the extra time taken will be 371/2-25 = 121/2 mins

Step-by-step explanation:
Answer:
The median value is better because it is not affected by the skewness of the data
Step-by-step explanation:
The median is better in representing the data of a stem and leaf plot because the median value is not affected so much by outliers and skewness of the data. for example: for a downward skewed stem and leaf plot the value of the median is greater than the mean value
Hence the median value is a better representation of the central tendency
Given that the coordinates of the point A is (2,7) and the coordinates of the point B is (6,3)
We need to determine the midpoint of A and B
<u>Midpoint of A and B:</u>
The midpoint of A and B can be determined using the formula,
Substituting the points (2,7) and (6,3) in the above formula, we get;
Adding the numerator, we have;
Dividing the terms, we get;
Thus, the midpoint of the points A and B is (4,5)
