Answer:
Step-by-step explanation:
160lb.
The mean of the weights of a group of 100 men and women is 160lb. If the number of men in the group is 60 and the mean weight of the men is 180lb, what is the mean weight of the women? For a set of data, the lower quartile is 19, the median is 31, and the upper quartile is 48.
Slope of this line is a perfect 1
A=s^2, where s is a side length, and we are told A=150ft^2 so:
s^2=150
s=√150
s≈12.25 ft
So you would need a piece of carpet 13ft by 13ft
