I need help pls, thank you, friends :)

No, the scenario won't earn you enough money

Explanation:

You work 4 hours with your uncle, at $8 an hour, so that means you earn 4*8 = 32 dollars.

You work 12 hours online, at $4 an hour, so you earn 12*4 = 48 dollars.

In total, you earn 32+48 = 80 dollars overall when combining the two lines of work.

The total 80 is smaller than 120, so this scenario isn't possible if you want to aim for $120 or more. You'll need to work more hours somehow.

the answer is:

mean: 6

mad: 2.14

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
