What is an arithmetic operation?
The four fundamental operations of arithmetic are addition, subtracting, multiplying, and dividing two or more numbers. Included is the study of integers, especially the order of operations, which is essential for all other aspects of mathematics, notably algebra, information management, and geometry.
As per the data given in the question,
7.2 × 4= $28.8
$28.8 - 10=18.8
which means that she saves $18.8 per week.
18.8 × 12 = 225.6
She has collected 225.6 dollars over 12 weeks.
225.6 × 0.25 = 56.4
she received $56.4 from her grandparents,
$56.4 + $225.6 = $282
she has $282.

she saves 18.8 dollars per week.
18.8 times 12=225.6
after 12 weeks she has saved 225.6 dollars
225.6 times 0.25=56.4
her grandparents giver her 56.4 dollars
56.4+225.6=282
she has 282 dollars

Let's rewrite the given function notation by using y term.
f(x) = 6x-1
i.,e y = 6x-1
Let's solve this equation for x;
Add 1 to both sides we get;
y+1 =6x
Divide both sides by 6 we get;
Now, switch the "x" and "y" we have;
In the function notation:

Answer:
(a) What is the probability that you roll a 6?
1/6
(b) What is the probability that you either roll a 6 or do not roll a 6?
1
(c) What is the probability that you don't roll a 6?
5/6
Step-by-step explanation:
(a) What is the probability that you roll a 6?
In a 6- sided cube, a 6 occurs only once. That is only one face is labelled 6. Therefore, the probability that you roll a 6 is;
(number of faces labelled 6)/(totals number of sides) = 1/6
(b) What is the probability that you either roll a 6 or do not roll a 6?
The probability of rolling a 6 was found to be, 1/6.
On the other hand, the probability of not rolling a 6 is;
(number of faces not labelled 6)/(totals number of sides) = 5/6
Therefore, the probability that you either roll a 6 or do not roll a 6 is;
1/6 + 5/6 = 1
These two events are mutually exclusive and exhaustive.
(c) What is the probability that you don't roll a 6?
The probability of not rolling a 6 is;
(number of faces not labelled 6)/(totals number of sides) = 5/6
We have 5 faces not labelled 6 out of 6 possible faces or outcomes
