If the charge on a single-use bag is 25 fils, then the notations that shows the amount of dirhams that the store will get after one year can be expressed as 0.25x.
Given that the charge on single-use bag is 25 fils.
We are required to give the express the amount of dirhams that the store will get after one year.
Equation is the relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It may be a linear equation,quadratic equation,cubic equation and many more depending on the powers of variables that are present in the equation.
let the number that single use bag used in 1 year be x.
We know that there are 100 files in a dirham, so 25 fils will be 0.25 dirham.
Equation that shows the number of dirham that the store will get after one year=0.25x.
Hence if the charge on a single-use bag is 25 fils, then the notation that shows the amount of dirham that store will get after one year can be expressed as 0.25x.

Whether the events are dependent or not, the rule for conditional probability applies:
P(a|b) = P(a∩b)/P(b)
P(a|b)×P(b) = P(a∩b)
0.25×0.4 = P(a∩b) = 0.1
The appropriate choice is
C. 0.1
Question is nottttt clearrrrrrr
Answer:
You'll have a <u>closed circle at x = 2</u>, and <u>shading to the left</u>
See the diagram below
=========================================================
Explanation:
The fractions here are 3/7 and 21/2. The denominators of which are 7 and 2 respectively. The LCD is 7*2 = 14.
If we multiply both sides by 14, then this will clear out the denominators and make the fractions go away.
- 14*(3/7) = (14*3)/7 = 42/7 = 8
- 14*(21/2) = (14*21)/2 = 294/2 = 147
So if we multiplied both sides by 14, then we have these steps
--------------------------
Let's isolate x
The graph of this will consist of a closed or filled in circle at x = 2. We shade to the left to represent numbers smaller than 2.
So either x = 2 or x < 2.
If we used an open hole at 2, then we wouldn't be including 2 (but we want to include this endpoint).
See the diagram below.
