5W = 24D is the expression that represents the change in the rate of dosage as per the weight.
What is an expression?A mathematical expression is a sentence that includes numbers, variables, or both. The equal symbol is never used in expressions. Here are a few phrases as examples. A mathematical statement stating the equality of two expressions is known as an equation.
Given the relation between dosage and the weight of a medicine
Children's Fever Medicine
(given every 4-6 hours, as needed)
Weight: 24 lbs 36+ lbs 48+lbs 60+lbs 72+ lbs
Dosage: 5 mL 7.5 mL 10 mL 12.5 mL 15 mL
ratio of weught and dose
24/5 = 36/7.5 = 48/ 10 = 60/12.5 = 75/15
=> 4.8 = 4.8 = 4.8 = 4.8 = 4.8
Since weight is directly proportional to the dosage
let W be the weight of the child and D be the Dose of the medicine
Thus, Relation between them:
=>W/D = 24/5
=> 5W = 24D
Therefore, The formula that describes the change in dosage rate in relation to weight is 5W = 24D.

What is cartesian coordinate system?
The coordinate system in where the location of a point is identified by a pair of numerical terms and that has two reference axis is termed as cartesian coordinate system.
In cartesian plane the reference axis are named as X - axis and Y -axis.
In this system, location of a point p is identified by p (x, y) that means x is the x coordinate of point p and y is the y coordinate of point p. Generally, X-axis is horizontal, and Y-axis is vertical. Both axes are intersected at the origin.
What is the distance of 2/3 from the horizontal axis in cartesian plane?The point coordinate 2/3 denotes the location of a point with respect to a reference direction in the polar coordinate system. In the polar coordinate system, the angle between horizontal axis and a reference point is called polar angle. we know tan angle = vertical coordinate / horizontal coordinate.
hence, tan angle = 2/3
for this reason, if we imagine a cartesian coordinate system 2 is the y coordinate and 3 is the x coordinate.
Finally, the distance of 2/3 from the horizontal axis is 2.

We have to given that;
There are three angles are shown in figure.
That is,
⇒ 59°, 108°, and 81°.
Now, We know that;
Sum of all four angles is 360°.
So, We can formulate;
⇒ 59° + 108° + 81° + x = 360°
⇒ 248° + x = 360°
⇒ x = 360° - 248°

The circumference of a circular field is 276 yards. What is the diameter of the field?
Round your answer to the nearest hundredth.
Answers
C = πd or C = π2r
So we already have the circumference which is 276 yd
276 = πd
We just need to find the diameter, so we divide d/1 on both sides:
d/276 = π
Now we divide 276/1 on both sides:
d = 276/π
Now we solve
d = 87.90

What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. To find the probability of a single event to occur, first, we should know the total number of possible outcomes.To learn more about distribution refer to:

A tower that is 103 feet tall casts a shadow 117 feet long. Find the angle of elevation of the sun to the
nearest degree
Answers
Answer:
[tex]\theta=61.68^{\circ}[/tex]
Step-by-step explanation:
Given that,
The height of a tower, h = 103 feet
The height of its shadow, H = 117 feet
The height of tower is perpendicular and the height of shadow is hypotenuse of a right angled triangle. We can use trigonometry such that,
[tex]\sin\theta=\dfrac{h}{H}\\\\\theta=\sin^{-1}(\dfrac{103}{117})\\\\\theta=61.68^{\circ}[/tex]
So, the angle of elevation of the sun is equal to [tex]61.68^{\circ}[/tex].
Three line segments have measures of 18 units, 12 units, and 10 units. Will the segments form a triangle?
Does it form a triangle?
Answers
No, the segments will not form a triangle based on the line segments provided.
For three line segments to form a triangle, they must satisfy the triangle inequality theorem. The triangle inequality theorem states that for any triangle, the sum of the lengths of any two sides of the triangle must be greater than the length of the third side.
This is because if the sum of the lengths of any two sides is less than or equal to the third side, it would not be possible to form a triangle with those side lengths, as the two shorter sides would not be able to reach the longer side to form the triangle.
In this case, the sum of the two shorter segments (12 units + 10 units) is 22 units, which is less than the measure of the longest segment (18 units). Therefore, the three segments will not form a triangle.
