Answer:
The area of this park is 130.60 square miles.
Step-by-step explanation:
Given : The scale of a certain map is
inch = 16 miles. A square park is represented on the map by a square with side length
inch.
To find : What is the actual area of this park?
Solution :
The scale of a certain map is
inch = 16 miles.
Let the side length of
inch = x miles.
So, 




The side length of a square is 11.428 miles.
The area of the square is
.


To nearest hundredth,
The area of this park is 130.60 square miles.
Answer:
142m
Step-by-step explanation:
This problem can be solved by simply using the pythagorean theorem, as you stated at the beginning of the problem, which is: 
You are given the <em>a</em> side and <em>b</em> side that are needed for this equation, so it's all a matter of plugging in the information you have:





Now, because the <em>c</em> is still squared, you must take the square root of 20200 in order to get the length of just side <em>c</em>:
≈142m
Answer:
x = 4
Step-by-step explanation:
2x/2 = 8/2
x =4
Answer:
a. Check the attached image
b. The Pr(Y > 2) = ½
c. The mean is 2.4
d. The standard deviation is: 2.72
e. The exact value is 1 because it is certain from the given data that any probability will fall within that range.
Step-by-step explanation:
a. An image showing the step by step solution is attached.
b. P(Y > 2) = P(3) + P(4)
= 2/10 + 3/10 = 5/10 = ½
c. The mean is 2.4
d. The standard deviation is: 2.72
e. Check the attached image for the steps.
