Additional Note: Associative Property is modifying the addendum grouping does not alter the number.

Answer: The friend is wrong.

Step-by-step explanation:

In this equation, they are doing the commutative property. Commutative property is a property that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The Associative Property of Addition is a property which means that rearranging the parentheses in an expression will not change the result. Clearly, they didn’t do that; they just switched the 7 and x around which is the commutative property.

This might be slightly confusing but I hope this helps :’)

A diagonal of a square is defined, [tex]d=a\sqrt{2}[/tex] where a is side of the square. Solve for a to get [tex]a=\frac{d}{\sqrt{2}}[/tex].

Now multiply a by 4 since that is the definition of a perimeter,

Answer:

5/9

Step-by-step explanation:

Number of players = 3

number of times game is repeated = 4

P( any person wins a game ) = 1/3

P ( any person does not win a game ) = 1 - 1/3 = 2/3

P ( any person wins no game in 4 attempts ) = ( 2/3 )^4 = 16/81

Note : each player has equal chance of winning

Find the probability that there is at least one person who wins no games

lets represent the probability of each player not wining a game with alphabet A

A1 = player 1 wins no game

A2 = player 2 wins no game

A3 = players 3 wins no game

Applying the inclusion-exclusion formula

P( A1 ∪ A2 U A3 ) = P(A1 ) + P(A2) + P(A3) - P( A1 ∩ A2 ) - P( A2 ∩ A3 ) - P( A1            ∩ A3 )  + P( A1 ∩ A2 ∩ A3 )

where

P( A1 ∩ A2 ) = P( A1 wins all games )

P ( A1 wins all games in 4 attempts ) = ( 1/3 )^4 = 1/81

P( A1 ∩ A2 ∩ A3 ) = P ( no players wins any game in 4 attempts ) = 0

Hence

P( A1 ∪ A2 U A3 ) = 16/81 + 16/81 + 16/81 - 1/81 - 1/81 - 1/81 - 0 = 5/9

The probability should be[tex]5\div 9[/tex]

Number of players = 3

number of times game is repeated = 4

P( any person wins a game ) = [tex]1\div 3[/tex]

P ( any person does not win a game ) = [tex]1 - 1\div 3 = 2\div 3[/tex]

P ( any person wins no game in 4 attempts ) = [tex]( 2\div 3 )^4 = 16\div 81[/tex]

Now

A1 = player 1 wins no game

A2 = player 2 wins no game

A3 = players 3 wins no game

So,

P( A1 ∪ A2 U A3 ) = P(A1 ) + P(A2) + P(A3) - P( A1 ∩ A2 ) - P( A2 ∩ A3 ) - P( A1            ∩ A3 )  + P( A1 ∩ A2 ∩ A3 )

[tex]= 16\div 81 + 16 \div81 + 16\div 81 - 1 \div 81 - 1 \div 81 - 1 \div81 - 0 \\\\= 5 \div9[/tex]

Answer:

5 dimes and 2 quarters

Step-by-step explanation:

A dime is worth 10 cents. To figure out how many dimes it takes to get to fifty, do:

[tex]50/10[/tex]

Doing this will give you the answer of 5 dimes.

A quarter is worth 25 cents. To figure out how many dimes it takes to get to fifty, do:

[tex]50/25[/tex]

Doing this will give you the answer of 2 quarters.

Answer:

1. 5 Dimes

2. 2 Quarters

Step-by-step explanation:

A fifty-cent coin can be written as $0.50. A dime can be written as $0.10. Now you just solve with the simplest math by figuring out how many 0.10's you need to get 0.50. This would be 5

Now a quarter can be written as $0.25. Now you just do the same thing as before. So you would need two $0.25 to get $0.50

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

Answer:

no

Step-by-step explanation:

First, we need to plug in the ordered pair inside the equation with -3 as x and 5 as y.

-3=5(5)-20  Multiply 5 times 5.

-3=25-20    Subtract 20 from 25.

-3=5

-3 does not equal 5, so the ordered pair is not a solution.

Answer:

1/36

Step-by-step explanation:

There is a 1/6 probability the first die will be a 6

There is a 1/6 probability the second die will be a 6

There is a (1/6 * 1/6) = 1/36 probability that both will be a 6

Answer:

a = 3/28

Step-by-step explanation:

To start solving for a variable, you need to isolate it.

-4/3b = 4a

-4/3 divided by 4 equals -4/12 or -1/3

a = -1/3b

To completely solve for a we need to plug it back in and solve for b.

b = (4(-1/3b)) - 3/4

b = -4/3b - 3/4

7/3b = -3/4

b = -9/28

Finally, we can plug b back in to the previous equation we got for a to solve for a.

a = -1/3(-9/28)

a = 3/28

Furthermore, we can check if this is correct by plugging in 3/28 for a into the original problem and see if we get what we got for b (-9/28)

Answer:

B. A reflection

Answer:

The expression is equal to 1 over 12 factors of r

Multiplying the exponents will create an equivalent expression.

Step-by-step explanation:

We are given the following in the question:

[tex](r^-^4)^3[/tex]

[tex](x^m)^n=x^m^n[/tex]

[tex]x^-^a=\frac{1}{x^a}[/tex]

Thus, we can simplify the given expression as:

[tex](r^-^4)^3[/tex]

= [tex]r^-^1^2[/tex]

= [tex]\frac{1}{r^1^2}[/tex]

Thus, the correct answer is:

Option 2) The expression is equal to 1 over 12 factors of r

Option 4) Multiplying the exponents will create an equivalent expression.

The measure of supplement of angle A is 109°.

Here,

Measure of angle A is 71°.

We have to find the supplement of angle A.

What are Supplementary angles?

Two angle are called supplementary angles if sum of both angles are 180°.

Now,

Measure of angle A is 71°.

Let the measure of its supplement is x°.

Then, By definition of supplementary angles;

x° + 71° = 180°

x° = 180° - 71°

x° = 109°

Therefore, The measure of supplement of angle A is 109°.
