The first picture answer is H, because you plug in (-2/3) for x in the equation.
Im not sure what you are asking for in the second picture, but I think the answer is (3,8) if you are looking for a point, or 7 if you are just subtracting 12 from 5.
The third picture answer is x=20, because you you look at the table and find f(30), you will see across from it will be x=20
For the last picture the answer is F.) because you plug in all the numbers and will get the answer choice F.
Answer:
See below.
Step-by-step explanation:
The mean of set A = 4.3625
The mean of set B = 4.1.
The means are very close.
The median of set A = 4.5
The median of set B = 3.5.
The mean and median of Set A are quite close so we can say that the data is close to Symmetrical.
In the case of set B the mean and median are further apart so the data is more skewed . it is skewed towards the lower values (to the left).
60 minutes being in each hour, then 60 seconds in each minute multipled will be 3600 seconds in one hour. multiply by 2 to find 5-6 then 6-7 and you end up with 7200 seconds :)
1-7 so 6 is your range i think!
