Match the vocabulary word to its correct definition. 1. element 2. null set 3. set 4. subset A a set containing no elements; also called the empty set B a member of a set C set A is a subset of set B if all of the elements of set A are contained in set B or it is the empty set D a collection or group of objects indicated by braces, { }

1. Element - B. A member of a set

2. Null set - A. A set containing no elements; also called the empty set

3. Set - D. A collection or group of objects indicated by braces, {}

4. Subset - C. set A is a subset of set B if all of the elements of set A are contained in set B or it is the empty set

hope this helps!

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
