Hope this helps!!
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.

Complete question :
The birthweight of newborn babies is Normally distributed with a mean of 3.96 kg and a standard deviation of 0.53 kg. Find the probability that an SRS of 36 babies will have an average birthweight of over 3.9 kg. Write your answer as a decimal. Round your answer to two places after the decimal
Answer:
0.75151
Step-by-step explanation:
Given that :
Mean weight (m) = 3.96kg
Standard deviation (σ) = 0.53kg
Sample size (n) = 36
Probability of average weight over 3.9
P(x > 3.9)
Using the z relation :
Zscore = (x - m) / (σ / √n)
Zscore = (3.9 - 3.96) / (0.53 / √36)
Zscore = - 0.06 / 0.0883333
Zscore = −0.679245
Using the Z probability calculator :
P(Z > - 0.679245) = 0.75151
= 0.75151
