Answer: There is an association because the distribution of correct guesses is the same among the mint groups.
Step-by-step explanation:
We would have to see the graph but I know it's either B or C because the other answer choices don't make sense. I chose B because it seems like the most logical choice of the two.
Exact Area = 98pi
Approximate Area = 307.8760800518 (use calculator stored version of pi)
Approximate Area = 307.72 (using pi = 3.14)
Units are in square millimeters
======================================================
Explanation:
In 60 seconds, the hand sweeps out a full circle of radius 14. The area of this circle is
A = pi*r^2 = pi*14^2 = 196pi
Half of this is what the hand sweeps out in 30 seconds, so A/2 = (196pi)/2 = 98pi is the exact area it sweeps out. Your calculator would then show 98pi = 307.8760800518 approximately
If instead you use pi = 3.14, then the approximate area is 98*3.14 = 307.72
Step-by-step explanation:
Area = 14/5 m2
L = 2m
W = ?
area = LxW
14/5 = 2xW
2.8 = 2xW
W = 2.8/2
W = 1.4m
I wish I could help you out on that
Answer:
30/7
Step-by-step explanation:
So we have the equation:

Combine like terms:

Add:

Add 28 to both sides:

Divide both sides by 7:

So, our answer is 30/7
Or approximately 4.2857 :)
