Answer:
2
Step-by-step explanation:

Answer:
$200
Step-by-step explanation:
You can take .1 times $2000 since 1-tenth is equal to .1
or you can 1 over ten times 2000 over 1 which makes 2000 over 10 and you divide 2000 by 10 to get $200
the larger the sample the more accurate the prediction
so since Tim looked at a larger quantity of coins his would be more accurate
2) AAA
or the angle-angle-angle postulate.
There are congruent angles (as seen by the lines on the angles) that indicate this is the accurate answer.
