Answer:
E. 31.64
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between the legs of a right triangle:
Tan = Opposite/Adjacent
You are given trig values for 36°. That means ...
tan(36°) = 23/x
x = 23/0.727 ≈ 31.64
She then lets a real rat run the maze and measures the long run to be 13 feet.

What is a normal distribution?</h3>
A function that represents the distribution of many random variables as a symmetrical bell-shaped graph.
We first need to find the z-score which is given by applying the following formula:
z-score = (X-μ) ÷ σ
Where: μ is the average, σ is the standard deviation, X is the sampled value.
Therefore,
z-score = (13-14.8) ÷ 2.4
z-score = -0.75
Finding the probability, or the p-value by looking upon the z-table
P(Z<z) = P(Z<-0.75) = 0.2266
The conclusion that the biologist could make is that out of 1000 virtual rats, there are 0.2266×1000 = 226.6 ≈ 227 virtual rats that run the maze with a length of 13 feet.
Hence, She then lets a real rat run the maze and measures the long run to be 13 feet.

Displacement x would be in terms of length, while t would be in terms of time.
Therefore the equation would have units of:
length = (b)*time^2
b = length/(time^2)
Therefore, the units of the constant b should be in length per time^2 (for example, in m/s^2, such as in acceleration).
