<u>Answer-</u>
Ed exhibited the most variable year to year performance over this 5 year span.
<u>Solution-</u>
Most variable performance means varying performance or non-consistence performance.
As shown in the graph,
Jill's performance was constant throughout 2005-07.
Ralph's performance was constant throughout 2006-07 and also in 2008-09.
Tina's performance was constant throughout 2007-09
Sam's performance was constant throughout 2008-09.
All of them has been consistence for at-least once. But, in case of Ed, throughout the time, his performance was in-consistence or variable.
<u>Given</u>:
Given that TUV is a right triangle with measure of ∠V=90°
The measure of ∠U = 55°, and the length of VT is 82 feet.
We need to determine the length of TU.
<u>Length of TU:</u>
The length of TU can be determined using the trigonometric ratio.
Thus, we have;

where
, opp = VT and hyp = TU
Thus, we have;

Substituting the values, we have;

Simplifying, we have;



Thus, the length of TU is 100.1 feet.

We Know, speed = Distance / Time
Here, Distance = 2748 miles
Time = 6 hours
Substitute their values in to the expression,
Speed = 2748 / 6 = 458 Miles / Hour
So, the speed would be: 458 miles/hour
Hope this helps!
