Read carefully — this is an easy 2 point giveaway:

The total number of tickets is 150 and a is how many adult tickets and c is how many child tickets. The adult ticket is $10.25 and the child ticket is $7.75 so this has to go with the $$.

As more popcorn is sold, what is happening to soda sales?

Another question to think about, if you were to draw a line of best fit would the slope be negative or positive?

Read carefully and think thoughtfully about correlation vs causation..

Since all of the intervals are two years, we just need to find the smallest change:

For answer (1), it changed 12 (from 11 to 23)

Answer (2), 17 (from 16 to 33)

Answer (3), 19 (from 23 to 42)

Answer (4), 14 (from 33 to 47)

That’s it — 2 points!!

This question is categorization and is easy to figure out with some close reading:

A fifth degree expression has a highest power of 5 so that takes out answers (2) and (3) leaving (1) and (4).

A leading coefficient of 7 is exactly what it sounds like — does answer choice (1) or (4) have a first term that starts with a 7?

A constant of 6 is 6 without any algebra or variables so find that to confirm your answer!

We can either recognize the factoring as DOTS Difference of Two Squares and see that the 16 would be 4 x 4 (not 8 x 8). Then by checking the signs of the remaining answers (3) and (4) we would see that answer (4) would give us a trinomial and not the binomial given.

Another way to do this would be to use the TI-84:

Here is answer (1) compared to the original expression, um, not a match!

Below is answer (2) compared to the original expression. Also not a match!!

And now to check answer (3) and from the table voila!! also we only see one graph which means the Y= are the same

# Generous Scaled Score for CC Alg II Regents

Look at where the 65 is!!

The usual cut score for Alg 2/Trig has been in the 40’s. Don’t think anyone expected this to be at 25. Congrats to all the students who passed (and who even took it!) and to their teachers and families.

# June 2016 Brain Teaser Solution

No other numbers can be written.

No inequality symbols can be used like a “greater than” sign, a “less than” sign or “not equal to” sign.1 1 1 =6

2 2 2 =6

3 3 3 =6

4 4 4 =6

5 5 5 =6

6 6 6 =6

7 7 7 =6

8 8 8 =6

9 9 9 =6

0 0 0 =6There can be multiple answers for one equation.

(1+1+1)! = 3! = 3 x 2 x 1 = 6

2 + 2 + 2 = 6

3 x 3 – 3 = 6

5 + 5/5 = 6

6 + 6 – 6 = 6

7 – 7/7 = 6

8 – sqrt(sqrt(8 + 8) = 2

9/sqrt(9) + sqrt(9) = 6

(0! + 0! +0!)! = 6
