Answer: Yes it can form a triangle and its a right triangle.
Step-by-step explanation:
Using the Pythagorean theorem we can see that the longest side (20) is our hypotenuse. From there you just check if its true. :)
Her average rate of the entire trip would be 2 hours since 12mph for 10 miles and 12 miles going 10mph would crossed each other out and have 10 miles go 10mph (1 hour) and 12 miles going 12mph(1 hour)
1+1=2
We can substitute<span> y in the second </span>equation<span> with the first </span>equation<span> since y = y. The solution of the </span>linear<span> system is (1, 6). You can use the </span>substitution method<span> even if both </span>equations<span> of the </span>linear<span> system are in standard form. Just begin by solving one of the </span>equations<span> for one of its variables.</span>
Answer:
A. 6.5
Step-by-step explanation:
First we find the average 
of the 9 data:
Where n is the data number, that in this case is 9.
The formula of the standard deviation 
is:
We replace the data and find the value of the standard deviation:
We approximate the number and the solution is 6,5
