Answer:
177 and 178
Step-by-step explanation:
First, the expression for the 2nd mile marker is x+1.
Now, you add x and x + 1 together to get 2x + 1
Next, make 2x + 1 equal to 355
Now subtract 1 and then divide by two on both sides to get x = 177.
This means that the first mile marker is 177 and the next is 178.
It would be a 1 in 4 chance

An experiment value can either represent statistic or parameter
The value of the average (mean) weight at birth represents is parameter
<h3>How to determine if the value is statistic or parameter</h3>
The mean value is given as:

From the question, we understand that the value represents the average weight at birth of all babies born at hospitals in one state
The keyword "all" means that the value represents parameter
Hence, the value of the average (mean) weight at birth represents is parameter

17 + 2 = 19 km is 1/2 of the total length, that is,
19 = (1/2)h
(1/2)h = 19 multiply both sides by 2
h = 2*19
h = 38 km
The total length in kilometers is 38 km
