The 3 types of sides in a right triangle are hypotenuse, base, and perpendicular.

A triangle is a form of a two-dimensional polygon with three edges and vertices. It is divided on the basis of sides as a Scalene triangle, Isosceles triangle, and Equilateral triangle. It is also divided on the basis of angles as acute, obtuse, and right-angle triangles.

A right-angle triangle has one angle equal to 90° and the other two angle sums up to be 90°.  The angle formed by the base and perpendicular is 90°.

The hypotenuse is the longest side of the triangle and it is opposite of the right angle. The relation between the three sides is Hypotenuse∧2 = Perpendicular∧2 + Base∧2. this relation is also called Pythagoras theorem.

A monomial is an algebraic expression that consists of only one term. Examples of monomials include 4x², a + 6, and a + b + c + d.

In the given example, (a) 4x² is a monomial because it consists of only one term, 4x². (b) a + 6 is also a monomial because it consists of only one term, a + 6. (c) a + 6 + c is not a monomial because it consists of more than one term, namely a + 6 and c. (d) a + b + c + d is also not a monomial because it consists of more than one term, namely a, b, c, and d.

To calculate the value of a monomial, we must first determine its degree. The degree of a monomial is the sum of the exponents of its variables. For example, the degree of 4x² is 2 because it consists of only one variable, x, with an exponent of 2.

Once the degree of a monomial is determined, its value can be calculated by substituting the values of its variables. For example, if x = 3, then 4x² = 4(3)² = 36.

In summary, a monomial is an algebraic expression that consists of only one term. Its degree is the sum of the exponents of its variables. To calculate its value, substitute the values of its variables into the expression.

Answer:

Step-by-step explanation:

Part A.

An appropriate design for the new study to examine whether vitamin E oil reduces pain in patients suffering from bulging disks in the thoracic region of the back would be a randomized controlled trial (RCT). The study should include the following elements:

1.Treatments: The study should include two treatment groups, one receiving vitamin E oil injections and the other receiving a placebo (e.g. a neutral oil) injections.

2.Method of treatment assignment: Patients should be randomly assigned to either the vitamin E oil treatment group or the placebo group, to control for potential confounding variables.

3.Variables that should be measured: The study should measure the following variables:

-Pain levels: Pain should be measured using a validated self-reported pain scale (such as the Visual Analog Scale or the Numeric Rating Scale) before and after each treatment session.

-Patient's demographics: Age, sex, and medical history should be recorded to evaluate the effect of these factors on the treatment outcome.

-Number of treatments: The number of treatments should be recorded for each patient.

-Adverse effects: Any adverse effects should be recorded, such as redness or swelling at the injection site.

It is important to note that this is a simplified design and a real study would need to consider many other aspects such as sample size, statistical analysis, and ethical considerations.

Part B

If the study consisted of 100 young patients and 100 old patients instead of 200 patients aged 20-40, I would likely modify the study design. One reason is that age can be a confounding variable and could affect the outcome of the study. Studies have shown that age can affect pain perception and management, older adults have been found to have more chronic pain, and different pain management strategies might be more effective for different age groups.

I would modify the study design by including an age variable in the analysis and stratifying the sample by age, creating two subgroups (young and old patients) and comparing the results separately. This would allow us to see if there is any age-related differences in the effectiveness of vitamin E oil in reducing pain in patients suffering from bulging disks in the thoracic region of the back.

Another modification would be to include a larger sample size to ensure that there are enough patients in each subgroup to detect any potential differences in the effect of vitamin E oil on pain reduction between young and old patients.

It is important to note that this is a simplified design and a real study would need to consider many other aspects such as sample size, statistical analysis, and ethical considerations.

Part C

To construct 90% confidence intervals for the proportion of pain reduction for each treatment group, we can use the following steps:

1.Calculate the sample proportion of pain reduction for each treatment group:

For the Vitamin E oil group, the proportion of pain reduction = (52 / 100) = 0.52

For the Placebo group, the proportion of pain reduction = (35 / 100) = 0.35

2.Calculate the standard error (SE) for each proportion:

SE = sqrt( (p * (1-p)) / n )

Where p is the sample proportion and n is the sample size.

For the Vitamin E oil group, SE = sqrt( (0.52 * (1-0.52)) / 100) = 0.049

For the Placebo group, SE = sqrt( (0.35 * (1-0.35)) / 100) = 0.045

3.Calculate the margin of error (ME) for each proportion:

ME = z * SE

Where z is the critical value for a 90% confidence level, which is approximately 1.645.

For the Vitamin E oil group, ME = 1.645 * 0.049 = 0.0806

For the Placebo group, ME = 1.645 * 0.045 = 0.0743

4. Calculate the lower and upper bounds of the 90% confidence intervals for each proportion:

Lower bound = p - ME

Upper bound = p + ME

For the Vitamin E oil group, the 90% confidence interval is:

0.52 - 0.0806 = 0.4394 and 0.52 + 0.0806 = 0.6006

For the Placebo group, the 90% confidence interval is:

0.35 - 0.0743 = 0.2757 and 0.35 + 0.0743 = 0.4243

Therefore, the 90% confidence interval for the proportion of pain reduction for the Vitamin E oil group is (0.4394, 0.6006) and the 90% confidence interval for the proportion of pain reduction for the Placebo group is (0.2757, 0.4243)

The volume of the storage compartment is 1246 cube ft.

In the given question, we have to find the volume of the storage compartment.

The diagram of the question is given below.

If we see the diagram it forms two recatangle with the lengths given below.

As we know that the volume of the cuboid is

V = LBH

where, L = length, B = breadth, H = Height

Now finding the volume of the cuboid A.

So V(A) = 10*8*15

V(A) = 1200 cube ft

Now finding the volume of the cuboid B.

So V(B) = 2*8*3

V(B) = 48 cube ft

Now the volume of the storage compartment is the sum of the volume of cuboid A and volume of the cuboid B, then we subtract 2 ft because we count the 2 ft of height two times.

The volume of storage compartment = volume of the cuboid A + volume of the cuboid B - 2 ft

The volume of storage compartment = 1200 + 48 - 2

The volume of storage compartment = 1248 - 2

The volume of storage compartment = 1246 cube ft

To find the area of a triangle with 3 unequal sides, you can use Heron's Formula.

This formula states that the area of a triangle (A) is equal to the square root of s(s-a)(s-b)(s-c), where s is half of the perimeter of the triangle and a, b, and c are the lengths of the sides of the triangle.

1. Calculate the perimeter of the triangle by adding together the lengths of all three sides.

2. Divide the perimeter by two to find s.

3. Plug in the lengths of the three sides and the value of s into Heron's Formula to calculate the area of the triangle.

A = √s(s-a)(s-b)(s-c)

The value of t in the trigonometric equation are The value of t is cos-1(-3 ± 1)

The study of correlations between triangles' side lengths and angles is known as trigonometry. The field was created in the Hellenistic era in the third century BC as a result of the use of geometry in astronomical research.

One of the most significant areas of mathematics is trigonometry. The terms "Trigonon" and "Metron," which imply triangle and measure respectively, are combined to produce the word "trigonometry." It is the examination of how a right-angled triangle's sides and angles relate to one another. It is therefore helpful to use formulae and identities based on this connection to determine the measure of a right-angled triangle's unknown dimensions.

In trigonometry, there are six fundamental ratios that are used to create a connection between a right triangle's side-to-angle ratio and its angle. If the angle created by the base and hypotenuse of a right-angled triangle is, then

sin θ = Perpendicular/Hypotenuse

cos θ = Base/Hypotenuse

tan θ = Perpendicular/Base

Now,

sin2(t) = Gcos(t)

I — cos2(t) — 6cos(t) = O

cos(t) = -3 ± 1
