<span>The identity element when applied does not change the other elements hence in multiplication 1x7=7 and 1x5=5 the elements 5 and 7 do not change for addition its 0 such as 0+10=10.

Answer:
The least number of bills you could use for any item is using just 5 to pay for the doll.
Step-by-step explanation:
For any of these, you have to break the number down into its largest parts. Take the doll for examples.
$18 = $10 + $8 = $10 + $5 + $3 = $10 + $5 + $1 + $2 = $10 + $5 + $1 + $1 + $1
Once you have only bill amounts, you can count the number and see how many bills you have to use. Repeat this process for each one.
Answer:
0.0321
Step-by-step explanation:
This can be found by binomial probability distribution as the probability of success is constant. There are a given number of trials. the successive tosses are independent.
Here n= 5
The probability of getting a four in a roll of a die = 1/6
The probability of not getting a four in a roll of a die = 5/6
The probability of getting exactly three 4s in five throws is given by
5C3 (1/6)³ (5/6)² = 10 (0.0046) (0.694)= 0.0321
Do Pythagorean Theorem because a rectangle divided in diagonals form right triangles
A^2+b^2=C^2
Plug in the correct numbers and solve
A and B can be switched around but C is always the longest diagonal side which is called the hypotenuse not the Adjacent sides that form a right angle
So with correct solving you should get 5.
