For the given set, first calculate the number of subsets for the set, then calculate the number of proper subsets. {18, 8, 14, 9
kicyunya [14]

Answer:

Subsets of the given set = 32

Proper subset of the given set = 31

Step-by-step explanation:

Given set is {18, 8, 14, 9, 6} having 5 elements.

We know number of subsets of a set having n elements are represented by

2^{n}

where n is the number of elements in the set.

Therefore, subsets of the given set = 2^{5}

= 32

Since original set itself is a subset of its own, is not a proper subset.

Therefore, proper subset of a set = 2^{n}-1

= 2^{5}-1

= 32 - 1

= 31

NO LINKS I NEED REAL ANSWERS <br> what are the 2 missing numbers on the blanks?
zavuch27 [327]

Answer:

Step-by-step explanation:

P1 = (2000, 1000)  in the form (x1,y1)

P2 = (2012, 3400) in the form (x2,y2)

m = (y2-y1 / x2-x1)

m = ( 3400-1000 ) / (2012 - 2000)

m = 2400 / 12

m = 200

y = 200x + 800

The outlier, 78, is removed from the data set shown.
bixtya [17]

Answer:

Well, in order o figure this out, you have to understand the definition or range.

Range is the difference between the lowest and highest values.

Since 78 use to be the highest number, the range was 55

Now when we remove the outlier, the new highest value is 45, decreasing the range to 22.

Hope this helps!
