Ineed with idk what to do and i know my answer is !

You did:

8 cars waxed / 3 hours = 2.666 cars waxed/hr

You found how many cars were waxed in an hour.

You should have found how many hours it took to wax one car, because you need to find how long it would take to wax 60 cars.

Instead of 8/3, you do:

3 hours / 8 cars waxed = 0.375 hours/1 car waxed

Now you multiply 0.375 with 60 = 22.5 hours

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
