A particular rat given n trials in a maze can run through the maze in t minutes, where: t=6+20

n+2
How many trials are needed so that the rat can run through the maze in exactly eight minutes?

Please check and clarify your Eq. I

don't believe it is correct.

To find the number of trials needed for the rat to run through the maze in exactly eight minutes, we need to solve the equation:

t = 8
t = 6 + 20 / (n + 2)

First, let's substitute the value of t into the equation:

8 = 6 + 20 / (n + 2)

Now, we can simplify the equation by subtracting 6 from both sides:

8 - 6 = 20 / (n + 2)

2 = 20 / (n + 2)

Next, we can cross-multiply to get rid of the fraction:

2(n + 2) = 20

Expanding the left side of the equation:

2n + 4 = 20

Subtracting 4 from both sides:

2n = 16

Finally, divide both sides by 2 to solve for n:

n = 16 / 2
n = 8

Therefore, the rat needs to have 8 trials in order to run through the maze in exactly eight minutes.
