Altho' I can easily guess what you're supposed to do here, I must point out that you haven't included the instructions for this problem.
I'll help you by example. Let's look at the first problem:
"Evaluate 6(z-1) at z-4."
Due to "order of operations" rules, we must do the work inside the parentheses FIRST. Replace the z inside (z-1) with "-4". We obtain
6(-4-1) = 6(-5) = -30 (answer.)
Your turn. Try the next one. If it's unclear, as questions.
Arrange them in ascending order
3,4,6,7,10
Median = the term in the middle = 6
The answer is D my dude don’t over think. Since it’s are multiply your answer choices till you reach 60.75
The answer is 10 hope this helps
