By making 80=2x+20 by corresponding angles in parallel lines you find x=30 because 2(30)+20=80

Which teacher exhibited the most variable year to year performance over this 5 year span?
Tanzania [10]

<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.

Ken is going to throw a biased dice once.
satela [25.4K]

Answer:

0.7

Step-by-step explanation:

Given a biased dice :

Probability of landing on 6 = P(6) ;

P(6) = 0.3

Recall :

P(A') = 1 - P(A)

Therefore,

If

P(6) = 0.3

P(not landing on 6) ; P(not 6) ;

P(not 6) = 1 - P(6)

P(not 6) = 1 - 0.3 = 0.7

Hence, Probability of not landing on 6 = 0.7
