Answer:
yea
Step-by-step explanation:
<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.
Step-by-step explanation:
x² + y² = 153 and y = -4x.
=> x² + (-4x)² = 153
=> x² + 16x² = 153
=> 17x² = 153
=> x² = 9.
Answer:
1771 possible ways
Step-by-step explanation:
In this case, we need to know first how many candidates are in total:
10 + 3 + 10 = 23 candidates in total.
Now, we need to choose 3 of them to receive an award. In this case, we have several scenarios, but as it's an award we can also assume that the order in which the candidates are chosen do not matter, so, the formula to use is the following:
C = m! / n! (m - n)!
Where m is the total candidates and n, is the number of candidates to be chosen. Replacing this data we have:
C = 23! / 3! (23 - 3)!
C = 2.59x10^22 / 6(2.43x10^18)
C = 1771
So we have 1771 ways of choose the candidates.
