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.

She could do 1 chore in 38 hours. you could make an equation by doing 3/x=114
Answer:
see explanation
Step-by-step explanation:
There is a common difference d in the values, that is
9 - 5 = 13 - 9 = 17 - 13 = 21- 17 = 4
To obtain a term in the sequence add 4 to the previous term, thus
t₉ = t₈ + 4 → C
(b)
Given the n th term formula 3n - 8
To find any term, substitute the term position n into the formula
(i) first term (n = 1), then
3(1) - 8 = 3 - 8 = - 5
(ii) tenth term (n = 10, then
3(10) - 8 = 30 - 8 = 22
(iii) 100 th term ( n = 100), then
3(100) - 8 = 300 - 8 = 292
The answer is y=40. hope this helps you
Yeah that equal to 9\28 because 4\7-n\4= 9\28 caused 16-7n \28 =9n\28
