Answer:
um the best i can say is 25% if thats the only info you give
Step-by-step explanation:
Hi again............. I am glad to help you again.
6x + 35 + 9x = 15x(x+4) -25
6x + 35 + 9x = 15x² + 60x - 25
15x + 35 = 15x² + 60x - 25
Now, we gonna put all the common terms together
15x - 60x + 35 + 25 - 15x² =
-45x + 60 - 15x² = 0
Now, we need to factorize
-15(x-1)(x+4)=0
Set factors equal to 0
x -1 = 0 or x + 4 = 0
x = 1 or x = 4
I hope that's help !

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.
