Answer:
The mean number of the children is 1.2
<em></em>
Step-by-step explanation:
Given
Children: 0, 1, 2, 1, 2
Required
Determine the Mean number
The mean of a set is calculated as follows;
Where x is the given set and n is the number of sets
In this case, n = 5 children
Hence;
<em>Hence, the mean number of the children is 1.2</em>
Answer: Algebraic linear expression
Step-by-step explanation:
An algebraic expression in mathematics is an expression built up from integer constants with
unknown variables, and the algebraic operations. For example, 6x² − 2xy + 20 is an algebraic expression which is quadratic in nature.
The general formular for algebraic linear expression is Y - MX - C
Combine like terms.
2x + 6 + 6x - 1
8x + 5
The cost of the roll = 125 * 45 = 5625 cents
5625 / 100 = 56.25 $
I'm not 100% sure if I'm doing it the right way, but I think the answer is the factorial of the number of letters divided by the factorials of the number of elements of each kind of element (in this case, the same letters)
9!/1!4!1!2!1!
= 9 · 8 · 7 · 6 · 5 · 4!/4!2!
= 9 · 8 · 7 · 6 · 5/2
= 9 · 4 · 7 · 6 · 5
= 63 · 120
= 7,560 permutations
