We can conclude that the ascending to descending order of the given fractions are, 7/5, 3/2, 11/4, 15/4, and 13/3.
What are fractions?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many parts of a particular size there are when spoken in everyday English. There are three main categories of fractions in mathematics. Proper fractions, incorrect fractions, and mixed fractions are these three types. The terms with a numerator and a denominator are called fractions.So, first, we need to find the LCM of all the denominators:
LCM of 5, 4, 2, 4, 3: 60(Refer to the attached image for calculation)Now, the fractions will be:
12(7)/60, 15(15)/60, 30(3)/60, 15(11)/60, 20(13)/6084/60, 225/60, 90/60, 165/60, 260/60So, ascending to descending order will be:
84/60, 90/60,165/60, 225/60, 260/60That is 7/5, 3/2, 11/4, 15/4, 13/3

The area of Desert A is five times the area of Desert B. If the sum of their areas is 600,000 square miles, find the area of each desert.
Answers
The area of Desert A is 500,000 square miles and the area of Desert B is 100,000 square miles.
What is area?
Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Area of a square is side × side.
Let the area of Desert A = x square miles
and the area of Desert B = y square miles
Given that, the area of Desert A is five times the area of Desert B,
i.e. x = 5y ...(1)
and the sum of their areas is 600,000 square miles,
i.e. x + y = 600,000 square miles ...(2)
Putting equation (1) in (2), we get
5y + y = 600,000
or 6y = 600,000 or y = 100,000 square miles
Using equation (1),
x = 5 × 100,000 = 500,000 square miles
Hence, the area of Desert A is 500,000 square miles and the area of Desert B is 100,000 square miles.

Find the measure of the angle at the center of atom B inside the triangle
Answers
The measure of the angle having the question mark, found using the law of sines is ? ≈ 140°
What is the law of sines?The law of sines states that the sine of an interior angle of a triangle is proportional to the the length of the side opposite to the angle.
The given parameters are;
The radius of circle A = 6.4
The radius of circle B = 4.0
The radius of circle C = 3.0
The measure of angle at C = 24°
The length of the segment AB = 6.4 + 4 = 10.4
According to the law of sines, we have;
[tex]\dfrac{sin(A)}{a} = \dfrac{sin(B)}{b} = \dfrac{sin(C)}{c}[/tex]
Where;
a = The length of the side opposite angle ∠A
b = The length of the side opposite angle ∠B
c = the length of the side opposite angle ∠C
From the diagram, the side opposite angle ∠C, is AB, which by comparison indicates that when side c = AB = 10.4
c = 10.4
Similarly, the side opposite angle ∠A = a = BC = 4 + 3 = 7
a = 7
The known information are therefore; ∠C = 24°, a = 7, c = 10.4
[tex]\dfrac{sin(A)}{a} = \dfrac{sin(C)}{c}[/tex]
[tex]\dfrac{sin(A)}{7} = \dfrac{sin(24^{\circ})}{10.4}[/tex]
[tex]sin(A) = \dfrac{sin(24^{\circ})}{10.4}\times 7[/tex]
[tex]\angle A = arcsine \left( \dfrac{sin(24^{\circ})}{10.4}\times 7\right)[/tex]
∠A + ∠B + ∠C = 180° (angle sum property of a triangle)
∠B = 180° - (∠A + ∠C)
Which gives;
[tex]\angle B = 180^{\circ} -\left(24^{\circ} + arcsine \left( \dfrac{sin(24^{\circ})}{10.4}\times 7\right)\right) \approx 140^{\circ}[/tex]

Unoccupied seats on flights cause airlines to loose revenue. Suppose a large airline wants to estimate its average number of unoccupied seats per flight over the past year. To accomplish this, the records of 225 flights are randomly selected, and the number of unoccupied seats is noted for each of the sampled flights. The sample mean and standard deviations are
x-bar =11.6 seats s=4.1 seats
Use Central Limit Theorem to help the company estimate its average number of unoccupied seats per flight over the past year.
Answers
The mean number of unoccupied seats per flight during the past year will lie between 11.15 and 12.05.
What is mean in mathematics?
There are many mean types in maths, particularly in statistics. Each mean serves to condense a specific set of data, frequently so that the general magnitude and sign of the data set can be better understood.
The arithmetic mean, also referred to as "arithmetic average," is a calculation that divides the total number of values in a data collection by their sum to get the central tendency of that set of numbers.
a) Calculations:
Degrees of freedom = n - 1 = 225 - 1 = 224
For 224 degrees of freedom and 90% confidence interval,
Critical t value = 1.652
Hence,
90% confidence interval will be:
[tex]11.6 \pm 1.652*4.1/\sqrt{225}[/tex]
[tex]11.6 \pm 0.45[/tex]
(11.15, 12.05)
b) Interpretation:
We are 90% confident that the population mean number of unoccupied seats will lie between 11.15 and 12.05
c) Caution with interpretation:
In this scenario, individual confidence interval should be calculated rather than mean number of unoccupied seats since we can't generalize this interpretation for individual flights.
d) To narrow a confidence interval, we can either increase the sample size or can decrease the confidence level.

The value of x is (t - ab)/ad while taking the subject x.
What does it mean when some variable is made the subject?Making x the subject of an equation or formula entails rearranging the equation or formula so that the x variable is equal to the other variables. The variable being calculated is the formula's subject. On one side of the equals sign, it is identifiable as the letter on its own. When changing a formula's subject, we rearrange the formula's components to create a new subject. In other words, alter the operation to do the opposite if you move a term from one side of the equals sign to the other. (An operation's inverse is known as the operation's opposite.)So, t = a(b + dx):
Now, solve taking the subject 'x' as follows:
t = a(b + dx)t = ab + adxt - ab = adx(t - ab)/ad = xx = (t - ab)/adTherefore, the value of x is (t - ab)/ad while taking the subject x.
