<span>Two separate bacteria populations grow each month and are represented by the functions f(x) = 3x and g(x) = 7x + 6. The function f(x) would be greater than the function g(x) when the value of x will correspond to the inequality f(x) is greater than g(x) that is 3x > 7x + 6.</span>
Answer:
D
Step-by-step explanation:
D is the correct answer
Answer:
It is not ''significant''
Step-by-step explanation:
Let's call the event
A : ''Answer a question correctly if a random guess is made''
Now we calculate the probability for the event A
![P(A)=\frac{cases where A occurs}{total cases}](https://tex.z-dn.net/?f=P%28A%29%3D%5Cfrac%7Bcases%20where%20A%20occurs%7D%7Btotal%20cases%7D)
In the exercise A occurs in only one way and the total cases are the number of possible answers
![Total cases = 18](https://tex.z-dn.net/?f=Total%20cases%20%3D%2018)
![P(A)=\frac{1}{18} =0.0555555](https://tex.z-dn.net/?f=P%28A%29%3D%5Cfrac%7B1%7D%7B18%7D%20%3D0.0555555)
An event B is ''significant'' if ![P(B)\leq 0.05](https://tex.z-dn.net/?f=P%28B%29%5Cleq%200.05)
![P(A)=0.0555555](https://tex.z-dn.net/?f=P%28A%29%3D0.0555555)
⇒A it is not a ''significant'' event
Subtract 1 because the number is going down by one
