Given: g(x) = Square Root x - 4 and h(x) = 2x-8 What are the restrictions on the domain of g ⋅ h? x ≥

Step-by-step explanation:

Given

Now, g of h i.e.

Put h(x) in place of x in g(x)

Now, the value inside square root must be greater than zero

part a: if the manager wants to award the sales team that has the most consistent earnings among its team members, which team should it choose and why? justify your answer mathematically.

team y has the most consistent earnings among the team members.

i considered the mean, median, and iqr of team y.

median is in the 50% of the data. iqr is the difference between the 75% and 25% of the quartiles. the value of the mean is above the value of the median. the mean is w/in the 50%-75% of the quartile.

part b: if the manager wants to award the sales team with the highest average earnings, which team should it choose and why? justify your answer mathematically.

team z has the highest average earnings. average refers to the mean of the group. among the three, team z has the highest mean value which is 1906.60
