Answer:
First Option
Step-by-step explanation:
First, we will find the equation for the total cost of the tickets.
Given x = Cost of 1 adult ticket
y = Cost of 1 Child ticket
Total Cost of tickets at $40:
2x + 4y = 40
To find which graph represent the cost of the tickets,
we can substitute x = 0 to find y and vice-versa.
If x = 0 ,
So when x = 0 , y = 10 which gives the coordinates (0,10).
Now if y = 0,
So when y = 0 , x = 20 which gives the coordinates (20,0)
This shows that this particular line passes through these 2 points and therefore the answer is the first option.
Answer:
A. For the situation presented, we find that the researcher assumes that the test with the new method will obtain results at a cost of less than $ 220.
the null hypothesis will be that the operation of the new method will cost not less than $ 220.
the alternative hypothesis will be that the operation of the new method will be less than $ 220
B. With the situation of the exercise we can affirm that the null hypothesis is not rejected, since the director has verified that the cost of the new method is below $ 220, so the new method can be implemented.
C. For this situation, it is observed that the null hypothesis has been rejected, so after verification, the manager has observed that the cost of the new method is less than $ 220, so the manager's proposal can be developed.
