Answer:
The third table.
Step-by-step explanation:
To have a proportional relationship there must be a constant rate of change
6-5 / 9-7 = 1 /2
5-3 /7-4 = 2/3
these are different so this is not a proportional relationship
10-8 /150-120 =2/30
8-5 /120-75 =3/45
these are different so this is not a proportional relationship
10-8 /12-10 =2/2 =1
8-6 /10-8 =2/2= 1
These are the same therefore it is proportional
Answer:
The profit function would be p(x) = 7x - 20
Step-by-step explanation:
In order to find this, start by listing just as asked.
p(x) = r(x) - c(x)
Now input the functions where indicated
p(x) = 12x - (5x + 20)
p(x) = 12x - 5x - 20
p(x) = 7x - 20
We have 9, 9.86, 9.42
So in order from least to greatest it would be: 9, 3 times pi, pi squared
not much on the probability of getting exactly one 4 on four rolls of a die
