PLEASE HELP NOW I WILL MARK BRAINLYST IF CORRECT What property of equality is demonstrated below? 2 + (5 + 6) = (2 + 5) + 6

The property demonstrated in the example 2 + (5 + 6) = (2 + 5) + 6 is The Associative Property.

We can tell this is the associative property because of what the associative property states. The associative property states that it doesn't matter where you put parenthesis when adding or multiplying numbers. Since we see an equation that has addition, and two equations being equal to each other, despite having different placements of parenthesis, we can see that this equation is demonstrating The Associative Property.

What is 2.1 times 3.2 find the missing partial products HELP.

vredina [299]

Given:

The area model for $2.1\times 3.2$ .

To find:

The value of $2.1\times 3.2$ and the missing values in the area model.

Solution:

2.1 can be written as 2 and 0.1 on the left side of the area model.

3.2 can be written as 3 and 0.2 on the top of area model.

Area of the four parts of the area model are:

$2\times 3=6$

$2\times 0.2=0.4$

$0.1\times 3=0.3$

$0.1\times 0.2=0.02$

The complete area model is shown below.

After adding all areas of the area model, we get

$6+0.4+0.3+0.02=6.72$

Therefore, the value of $2.1\times 3.2$ is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.

If the order of selection is considered relevant, in how many ways can k objects be selected from a set of n objects?

Hoochie [10]

hi,

You have to use a formula which is known as of binomial coefficient which is :

k among n is : C ( n /k) = n! / k! ( n-k)!

! = factorial

ex : 5 object among 8 is : C ( 8/5 ) = 8 ! / 5! * ( 8-5) !

As 8! = 8*7*6*5*4*3*2*1 = 40 320

As 5! = 5*4*3*2*1 = 120

as 3 ! = 3*2*1 = 6

then : 40 320 / 120 * 6

40 320 / 720 = 56

Conclusion : there is 56 way to select 5 object among 8 of them.

ps : you can also use Pascal Triangle to do such a thing.
