Answer:
the rate of change is 4.
Step-by-step explanation:
It is 4 because to find the rate of change you need to see how many pieces of corn (y) there are for every serving (x). If you see if you plug in the number three in between 2 and 4 for the servings and you follow the pattern of the table you will get 12. Then you subtract 8 from 12 and you get 4.
so basically the rate of change is the difference in corn for every serving.
Answer:
The expression is 
Step-by-step explanation:
Define the following events:
A: The student is enrolled in a foreign language class,
B: The student is enrolled in a technology class
We are given that 
Recall the definition of conditional probability: Let A, B be sets if P(B)>0, then, the probability of A given B is given by the expression
So, using this, we are asked for the probability 
which is
Answer:
<em>The minimum number of glasses of lemonade is 70</em>
Step-by-step explanation:
<u>Equations</u>
With the data provided, we can build a model for the profit that Michael gets for selling lemonade.
First, we set up the cost function. He purchased $12 in lemons and $4 in glasses. It makes a fixed cost of $16. He also spends $0.02 per glass of lemonade fot the sugar. Being x the number of glasses of lemonade Michael sells, the total cost is modeled by
C(x)=16+0.02x
The revenue for selling x glasses of lemonade is
R(x)=0.25x
The profit is
P(x)=R(x)-C(x)=0.25x-(16+0.02x)
P(x)=0.23x-16
To make profits:
0.23x-16>0
Solving for x
x>16/0.23
x>69.6
Since x must be an integer
The minimum number of glasses of lemonade is 70
