Answer: The correct answer is option B: There are between 15 and 20 green pieces in all 5 packages
Step-by-step explanation: The most important factor has been given which is, "Which statement about the candy pieces in the remaining packages is best supported by this information."
The information given is such that, the first package she opened had 4 green pieces and on this basis we can safely assume that all other packages have 4 green pieces as well. The second package had 3 green pieces and this based on this too we can safely assume that all other packages had 3 green pieces. Hence, all 5 packages can either have a total of 4 x 5 green candies which equals a total of 20 green pieces or, all 5 packages can have a total of 3 x 5 green candies which equals a total of 15 green pieces.
So according to Suzi's experiment, there are between 15 and 20 green pieces in all 5 packages.
Answer: 70%
Step-by-step explanation:
A percentage is a way of writing a fraction, but with a denominator of
100
Asking the question a different way makes it easier to understand.
What percent is
35
shirts out of
50
?
This indicates that there is a fraction.

Jaun has to use inverse before using those properties as they does not support subtraction but only addition.
<u>Solution:</u>
Given that , Juan used the expression 16 – 9 – 12 + 22 to find his profit for days 2 and 3.
He rewrote the expression as 16 + (–9) + (–12) + 22
Juan can use the associative and commutative properties to rewrite the expression again.
We have to explain why he had to use the additive inverse before he could use these properties.
Now, Associative property and commutative property true for addition.
i) a + (b + c) = (a + b) + c ---> Associative property of addition
ii) a + b = b + a --> commutative property of addition.
These properties not true for subtraction.
That's the reason Juan used additive inverse before applying these property.
Hence, jaun has to use inverse before using those properties as they does not support subtraction but only addition.
