The value of three subsets is [tex]n(x_{1})=36, n(x_{2})=9, & n\left(x_3\right)=54[/tex].
A set is a collection of objects or elements, grouped in the curly braces, such as {a, b, c, d}. If a set A is a collection of even number and set B consists of {2,4,6}, then B is said to be a subset of A, denoted by B⊆A and A is the superset of B.
The elements of sets could be anything such as a group of real numbers, variables, constants, whole numbers, etc. It consists of a null set as well.
If set A has {X, Y} and set B has {X, Y, Z}, then A is the subset of B because elements of A are also present in set B.

does a complex carbohydrate molecule have more or less atoms than a glucose molecule?
Note that a complex carbohydrate molecule has more atoms than a glucose molecule.
What is the rationale for the above response?Glucose is a simple sugar and is composed of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Complex carbohydrates, such as starches and fibers, are made up of multiple glucose molecules linked together, so they have more atoms than a single glucose molecule.
Sugar molecules are joined together in long, complicated chains to form complex carbohydrates.
Foods high in complex carbs include peas, beans, whole grains, and vegetables. In the body, both simple and complex carbohydrates are converted to glucose (blood sugar) and utilized as energy.

Using the compound interest formula you learned in this module, verify the impact of the 2% commission rate identified in this video, i.e., 63% difference. Specifically, compare 5% vs 7% compounded annually on the amount (A) over 50 years using principal (P) = $10,000. Then, calculate the difference in the two amounts (A) for the same principal over 10 years. What can you conclude from your analysis?
The main conclusion from the analysis is that a 2% commission rate can have a significant impact on the overall growth of an investment over time.
Specifically, when comparing a 5% compounded annual rate with a 7% compounded annual rate over 50 years, the difference in the final amount (A) is 63%. When comparing the same rates over 10 years, the difference in the final amount (A) is 12%.
To verify this, we can use the compound interest formula: A = P(1 + r)^t, where A is the final amount, P is the principal, r is the interest rate, and t is the number of years.
First, let's calculate the final amount (A) for a 5% compounded annual rate over 50 years:
A = $10,000(1 + 0.05)^50 = $10,000(1.05)^50 = $10,000(2.65892) = $26,589.20
Next, let's calculate the final amount (A) for a 7% compounded annual rate over 50 years:
A = $10,000(1 + 0.07)^50 = $10,000(1.07)^50 = $10,000(3.98107) = $39,810.70
To calculate the difference between the two amounts (A), we can subtract the first amount from the second amount:
$39,810.70 - $26,589.20 = $13,221.50
To calculate the percentage difference, we can divide the difference by the first amount and multiply by 100:
($13,221.50 / $26,589.20) * 100 = 49.86%
Now, let's calculate the final amount (A) for a 5% compounded annual rate over 10 years:
A = $10,000(1 + 0.05)^10 = $10,000(1.05)^10 = $10,000(1.63) = $16,300
Next, let's calculate the final amount (A) for a 7% compounded annual rate over 10 years:
A = $10,000(1 + 0.07)^10 = $10,000(1.07)^10 = $10,000(1.9079) = $19,079
To calculate the difference between the two amounts (A), we can subtract the first amount from the second amount:
$19,079 - $16,300 = $2,779
To calculate the percentage difference, we can divide the difference by the first amount and multiply by 100:
($2,779 / $16,300) * 100 = 17%

[tex]\textsf{i)} \quad n = 2\ln 2+\dfrac{5}{2}[/tex]
[tex]\textsf{j)} \quad x=\dfrac{5}{4}[/tex]
Step-by-step explanation:
Part hGiven equation:
[tex]20\left(\dfrac{1}{2}\right)^{\frac{x}{3}} = 5[/tex]
Divide both sides by 20:
[tex]\implies\left(\dfrac{1}{2}\right)^{\frac{x}{3}} = \dfrac{20}{5}[/tex]
[tex]\implies\left(\dfrac{1}{2}\right)^{\frac{x}{3}} =\dfrac{1}{4}[/tex]

Part iGiven equation:
[tex]2e^{2n-5} + 4= 36[/tex]
Subtract 4 from both sides:
[tex]\implies 2e^{2n-5} = 32[/tex]
Divide both sides by 2:
[tex]\implies e^{2n-5} = 16[/tex]
Take natural logs of both sides:
[tex]\implies \ln e^{2n-5} = \ln 16[/tex]
[tex]\textsf{Apply the power law}: \quad \ln x^n=n \ln x[/tex]
[tex]\implies (2n-5)\ln e = \ln 16[/tex]
Apply the law ln(e) = 1:
[tex]\implies 2n-5 = \ln 16[/tex]
Rewrite 16 as 2⁴:
[tex]\implies 2n-5 = \ln 2^4[/tex]
[tex]\implies 2n-5 = 4\ln 2[/tex]
Add 5 to both sides:
[tex]\implies 2n = 4\ln 2+5[/tex]
Divide both sides by 2:
[tex]\implies n = 2\ln 2+\dfrac{5}{2}[/tex]
Part jGiven equation:
[tex]\log_9x + 2\log_94= \log_920[/tex]
[tex]\textsf{Apply the log power law}: \quad n\log_ax=\log_ax^n[/tex]
[tex]\implies \log_9x + \log_94^2= \log_920[/tex]
[tex]\implies \log_9x + \log_916= \log_920[/tex]
[tex]\textsf{Apply the log product law}: \quad \log_ax + \log_ay=\log_axy[/tex]
[tex]\implies \log_916x= \log_920[/tex]
[tex]\textsf{Apply the log equality law}: \quad \textsf{If $\log_ax=\log_ay$ then $x=y$}[/tex]
[tex]\implies 16x=20[/tex]
Divide both sides by 16:

four patients receive?
Patient 1:
Patient 3:
DONE
✓ Patient 2:
✓Patient 4:
The blood type of each patient must be taken into account when determining which pint of blood they should receive.
Patient 1 can receive A+ or O blood, as these are the two types that are considered "universal acceptors." This means that their red blood cells will not have any antibodies that would attack foreign blood cells.
Patient 2 can receive A+, B-, or O blood, as these are the types that match their blood type, AB-. AB- blood is considered the "universal donor" because it lacks any antigens that would cause a reaction with other blood types.
Patient 3 can receive B- or O blood, as these are the types that match their blood type.
Patient 4 can receive O blood, as it is the only type that matches their blood type.
What is the Blood type about?Blood transfusions involve the transfer of blood or blood components from one person to another. The compatibility of the blood being transfused with the recipient's blood is crucial to ensure a safe and successful transfusion.
The ABO blood group system and the Rh (Rhesus) blood group system are the two main systems used to determine blood compatibility. The ABO system has four blood types: A, B, AB, and O. The Rh system has two possible results: positive or negative.
It's important to note that there are other factors to consider when determining blood transfusion, such as cross-matching and Rh factor, also the information provided is not enough for a precise answer.

The base radius and height of a circular cone are measured as 10cm
and 25cm respectively, with a possible error in measurement of as much as 0.1cm in
each. Using linear approximation, estimate the magnitude of maximum error in the
calculated volume of the cone.
The error is large in terms of the volume of the cone, which is about (1/3) * pi * 10^2 * 25 = (1/3) * 250 * pi cm^3
What does weight vs. volume mean?The volume of something determines how much space it takes up. Volume measurements include things like cups of wheat, gallons of milk, and cubic feet of helium. An object's weight serves as a proxy for its weightiness. Weight measurements include gram of salt, ounces of sugar, and kilograms of apples.
What are the three methods for gauging volume?Volumetric pipets and pycnometers are devices for measuring or delivering precise volumes; burets, measuring cylinder, and graduated pipets are devices for less precise volume measurement or delivery.
The partial derivative of the volume formula with respect to the radius is (2/3) * pi * r * h and with respect to the height is (1/3) * pi * r^2
So the maximum error in the calculated volume, due to the error in measurement of radius, is (2/3) * pi * 10cm * 25cm * 0.1cm = (2/3)* 25 * pi cm^3
and the error in height is (1/3) * pi * 10cm^2 * 0.1cm = (1/3) * pi cm^3
So the total error in the volume would be the sum of both error from radius and height which is (2/3)* 25 * pi + (1/3) * pi cm^3
The error is large in terms of the volume of the cone, which is about (1/3) * pi * 10^2 * 25 = (1/3) * 250 * pi cm^3

a six sided fair die is rolled 4 times. the produce that all four numbers rolled is a perfect square
The probability of rolling a perfect square on a fair six-sided die is 2/6 or 1/3 since there are two perfect squares (4 and 9) out of six possible outcomes, the probability of rolling a perfect square on all four rolls is 1/81.
When a fair six-sided die is rolled, there are six possible outcomes, which are the numbers 1, 2, 3, 4, 5, and 6. Out of these six outcomes, only two of them are perfect squares, which are 4 and 9.
Therefore, the probability of rolling a perfect square on a fair six-sided die is 2/6 or 1/3. Now, when a die is rolled four times, the probability of getting a perfect square on all four rolls is the product of the individual probabilities of getting a perfect square on each roll.
Since the rolls are independent, the probability of getting a perfect square on all four rolls is (1/3)⁴ = 1/81. Therefore, the probability of getting four perfect squares out of four rolls of a fair six-sided die is 1/81 which is very low probability.
