Answer:
y = 6.22
You can solve this in two ways.
1.) Use SOH CAH TOA:
I typically start off by labeling the sides of the triangle with H (hypotenuse), O (opposite), and A (adjacent). Because I need to figure out what y is when given an angle and 4, I will use CAH, or cosine.





2.) Use Law of Sines:
Solve for the last angle inside the triangle first.

Then use the angle you found (40°) in the equation.



Y = 4x - 4

The answer is 81.

Answer:
From the graph and data points, you can observe that Group B has a HIGHER range and has a greater variability. so it's NOT 1. 4. or 3. THEREFORE it's 2.
Explanation:
You start out by finding the mean (finding the sum of the data values and then dividing the sum by the number of data values)
and subtracting the first plot by the last in each graph.
(at least I think)
I've been through this topic. (it was a long time ago since I'm now in highschool so this might be different now as the grading curriculum has changed)
