For each of the following situations, explain why the combinations rule or the permutations rule should be used. (a) Determine the number of different groups of 5 items that can be selected from 12 distinct items. Use the permutations rule, since the number of arrangements within each group is of interest. Use the combinations rule, since the number of arrangements within each group is of interest. Use the permutations rule, since only the items in the group is of concern.
Answer:
Use the combinations rule, since the number of arrangements within each group is of interest.
Step-by-step explanation:
Arrangments rule:
Number of items to be arranged is the same as the number of places.
Permutations formula:
Number of items to be arranged is different of the number of places, and the order in which the items are placed is important(AB and BA are different outcomes).
Combinations formula:
Number of items to be arranged is different of the number of places, and the order in which the items are placed is not important(AB and BA are the same outcomes).
In this question:
5 items from a set of 12. The order in which the items are chosen is not important(for example, a book and a pencil would be the same as a pencil and a book). So the combinations formula is used, and the correct option is given by:
Use the combinations rule, since the number of arrangements within each group is of interest.

Solve for the value of z.
Answer:
13°
Step-by-step explanation:
2z + 5° + 5z - 6° = 90° { being complementary angles }
7z = 90° + 1°
7z = 91°
z = 91° / 7
z = 13°
Hope it will help :)
Answer:
2z+5+5z-6=90(right angle)
7z=90+1
z=91/7=13 is your answer

Answer:
10x+30
Step-by-step explanation:
Distributive property is distributing what is in the parentheses.
To do that on this problem you have multiply each of these numbers by 10!
10 times x is 10x
10 times 3 is 30
Put them back together and you get 10x+30!
I hope this helps, and have a great day! :)

Why do you think the cart rolls farther when it starts from a higher position?
Answer:
It has higher PE which can be converted into kinetic energy. The car also has had more work done on it when its at a higher position.
Step-by-step explanation:

solve for x=
don’t understand how to find the answer
Answer:
x=3
Step-by-step explanation:
Simplifying
9x + -4 = 3x + 14
Reorder the terms:
-4 + 9x = 3x + 14
Reorder the terms:
-4 + 9x = 14 + 3x
Solving
-4 + 9x = 14 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-4 + 9x + -3x = 14 + 3x + -3x
Combine like terms: 9x + -3x = 6x
-4 + 6x = 14 + 3x + -3x
Combine like terms: 3x + -3x = 0
-4 + 6x = 14 + 0
-4 + 6x = 14
Add '4' to each side of the equation.
-4 + 4 + 6x = 14 + 4
Combine like terms: -4 + 4 = 0
0 + 6x = 14 + 4
6x = 14 + 4
Combine like terms: 14 + 4 = 18
6x = 18
Divide each side by '6'.
x = 3
Simplifying
x = 3
Answer:
x = 3Explanation:
Write your equation
(3x + 14) = (9x - 4)Subtract 9x from both sides
3x + 14 − 9x = 9x − 4 − 9x
−6x + 14 = −4
Subtract 14 from both sides
−6x + 14 − 14 = −4 − 14
−6x = −18
Divide both sides by -6
−6x / -6 = −18 / -6
x = 3[ zyxx ]

Solve the inequality 15t > 180
Answer:
t>12
Step-by-step explanation:
t>180/15
then divide 180 by 15
and you gey t>12
The value of the given inequality is t> 12
What is inequality?inequality, In mathematics, a statement of an order relationship-greater than, greater than or equal to, less than, or less than or equal to-between two relation,
We have,
15t>180
According to the question
15t>180
t>180/15

A jar contains 38 red marbles numbered 1 to 38 and 38 blue marbles numbered 1 to 38 a marble is drawn at random from the jar
Answer:
[tex]P(Red) = 0.50[/tex]'
[tex]P(Odd) = 0.50\\[/tex]
Step-by-step explanation:
Given
[tex]Red = 38[/tex]
[tex]Blue = 38[/tex]
Required (Missing part of the question)
(a) The marble is red. (b) The marble is odd-numbered
Solving (a): Probability of Red.
This is calculated as:
[tex]P(Red) = \frac{Red}{Total}[/tex]
[tex]P(Red) = \frac{38}{38+38}[/tex]
[tex]P(Red) = \frac{38}{76}[/tex]
[tex]P(Red) = 0.50[/tex]
Solving (b): Probability of Odd
Since each marble type is numbered 1 to 38, then half of it are odd.
i.e. 19 odd numbered red marbles and 19 odd numbered blue marbles.
So, the probability of odd is:
[tex]P(Odd) = \frac{Odd}{Total}[/tex]
[tex]P(Odd) = \frac{19+19}{38+38}[/tex]
[tex]P(Odd) = \frac{38}{76}[/tex]
[tex]P(Odd) = 0.50\\[/tex]
The difference of two numbers is 2. Their sum is 12. What are the numbers?
Answer:
the numbers would be 5 and 7.
Step-by-step explanation:
"the difference of two numbers is 2."
7 - 5 = 2"their sum is 12."
7 + 5 = 12since the difference of 7 and 5 is 2 and the sum of 7 and 5 is 12, 5 and 7 are the numbers that fulfill the statement.
