To solve this problem, I would transfer this word problem into an equation with variables.
let the variable m stand for the amount of movies andrew rents.
5.00+1.25m=16.25
Now that we have our equation, we can just solve it like any other equation.
To do this, first, we would subtract 5.00 from both sides, resulting in the equation
1.25m=11.25
Next, we would divide both sides by 1.25, resulting in your final answer
m=9.
This means that Andrew rented 9 movies if his total was 16.25
2(x + delta x) = 2x + 2 delta x
so on top you have 2x + 2 delta x - 2x
which is 2 delta x
the delta x cancels out and you are left with just 2
so the limit is 2
Answer:
0.2406 = 24.06% probability that exactly two of the selected major customers accept the plan
Step-by-step explanation:
The customers are chosen without replacement, which means that we use the hypergeometric distribution to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:

In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
50 major customers, 15 would accept the plan.
This means that 
The utility selects 10 major customers randomly (without replacement) to contact and promote the plan.
This means that 
a. What is the probability that exactly two of the selected major customers accept the plan
This is P(X = 2).


0.2406 = 24.06% probability that exactly two of the selected major customers accept the plan
Answer:
either 10 or 1.6
