we can use distributive property
Distributive property:

now, we can apply this formula
and we get

we can see that there are two negative signs in last term
so, we can write as

so,
option-B
Answer:
A
Step-by-step explanation:
Range of a box plot is the highest value minus the lowest value.
<u>The picture attached shows which one is the highest value and which one is the lowest value.</u>
From our understanding and given graphs:
- The first Box Plot's Highest Value is 15 and Lowest Value is 3.
Range = Highest - Lowest = 15 - 3 = 12
- The second Box Plot's Highest Value is 16 and Lowest Value is 4.
Range = Highest - Lowest = 16 - 4 = 12
<u>Thus, the range of both the box plots are same</u>. Answer choice A is right.
There are 16 possible hands.
Choosing 3 aces from 4 possible is expressed by:

Choosing 1 queen from 4 possible is expressed by:

This gives us 4*4 = 16 possible hands.
The correct answer is -5n+1
Answer:
There are 13 cards for each suit so the first fraction is 13/52 and the next one is 13/51 as there is no replacement for the first card you pulled.
Multiplying them you get: 13/52*13/51= 169/2652,
Then you divide both sides by 13 to get: 13/204
So, the answer is C.
I hope this helps!
