Critical Thinking Question (5 pts.)
(You may use the back of the page to write your answer if needed). Here is a case-study for you to solve. Use what you learned
about blood types and Rhesus factor to solve this situation.
Two friends, Mike and Jake were returning late at night from a club in the same car. Suddenly, Mike, who was driving, lost control of
the car and they crashed into a big tree. Mike ended up with only a few bruises and scratches, but Jake got hurt.
Jake had internal bleeding and was taken to a hospital, but he lost a lot of blood and needed a blood transfusion. Mike, feeling
responsible for his friend's condition, wanted to donate blood to his friend. Both Mike and Jake had blood type O. So, in the ER, Mike
gave 2 pints of blood to Jake.
Two weeks later, Jake became anemic. So, Mike, being a good friend, decided to give blood again. However, after the second
transfusion, Jake went into an anaphylactic shock (severe immune response) and almost died.
What, do you think, was the problem here? Your answer should have two parts:
1. Explain, what happened in Jake's body after the first blood transfusion - why did he become anemic so soon after the transfusion?
(hint: it's not from bleeding)
2. Explain, what happened after the second blood transfusion - why did Jake go into an anaphylactic shock?

What is the Gaussian method?

The Gaussian method, also known as Gaussian elimination or row reduction, is a technique for solving systems of linear equations. It involves performing a sequence of operations on the rows of a matrix to transform it into an equivalent matrix that is in row echelon form or reduced row echelon form.

To use the Gaussian method, we need to set up a system of linear equations based on the given information. Let x, y, and z be the number of units of Metakeb, Mewesson, and Metekem produced per month, respectively. Then we have:

Machining department: 1200x + 1800y + 3000z = 1050(60)

Inspection department: 2400x + 1200y = 1160(60)

Assembly department: 600x + 3000y = 830(60)

Simplifying these equations, we get:

Machining department: 20x + 30y + 50z = 3150

Inspection department: 8x + 4y = 232

Assembly department: x + 5y = 139

Now we can use the Gaussian method to solve for x, y, and z:

Step 1: Write the augmented matrix:

| 20 30 50 | 3150 |

| 8 4 0 | 232 |

| 1 5 0 | 139 |

Step 2: Use row operations to get the matrix in row echelon form:

R2 → R2 - 4/5 R3

R1 → R1 - 20R3

| 0 -2 50 | 850 |

| 0 2 -4   | -28 |

| 1 5 0     | 139 |

R2→ -1/2 R2

R1 → R1 + R2

| 0 1 -25 | 407 |

| 0 1 -2 | 14 |

| 1 5 0 | 139 |

R1→ R1 - R2

| 0 0 -23 | 393 |

| 0 1 -2 | 14 |

| 1 5 0 | 139 |

R3→ R3 - 5R2

| 0 0 -23 | 393 |

| 0 1 -2 | 14 |

| 1 0 10 | 65 |

R1→ -1/23 R1

| 0 0 1 | -17 |

| 0 1 -2 | 14 |

| 1 0 10 | 65 |

R2 → R2 + 2R3

| 0 0 1 | -17 |

| 0 1 0 | 96 |

| 1 0 10 | 65 |

R3 → R3 - 10R1

| 0 0 1 | -17 |

| 0 1 0 | 96 |

| 1 0 0 | 235 |

Step 3: Read off the solution from the row echelon form:

z = -17

y = 96

x = 235

Therefore, the company should produce 235 units of Metakeb, 96 units of Mewesson, and 17 units of Metekem per month to use up all the available resources.

Callie will need a total of 112 feet of fence for the triangle DFG.

We can find the amount of fence needed by finding the relationship between both triangles and find the missing side.

The sum of all the sides of the triangle will be known as the perimeter of the triangle. we can use this knowledge to find the amount of fence needed.

Both triangles are similar and are in the ratio of 1:7To find the missing side of triangle DFG, we multiply the corresponding side of triangle BAC by 7 to find the missing side.

This will give us 7 x 7 = 49ft

To find the amount of fence needed for triangle DFG we add all the sides of triangle DFG which will be 49 + 35 + 28.

The total will be 112ft.

x - y = 4

________

2x = 24

Divide by 2.

The numbers are 12 and 8.

8 is the smaller number.

Answer:

To solve this problem, we can use the central limit theorem and the standard normal distribution.

The central limit theorem states that the distribution of sample means is approximately normal, with a mean equal to the population mean, and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

Let X be the systolic blood pressure of an individual in the population. We know that X is normally distributed with a mean of 120 and a standard deviation of 8.

Let Y be the sample mean blood pressure of a sample of 20 individuals. Then Y is also normally distributed, with a mean of 120 and a standard deviation of 8 / sqrt(20) = 1.7889.

We want to find the probability that the sample mean blood pressure is greater than 123. We can standardize this value using the standard normal distribution as follows:

Z = (Y - 120) / (8 / sqrt(20))

P(Y > 123) = P(Z > (123 - 120) / (8 / sqrt(20)))

= P(Z > 1.3363)

Using a standard normal distribution table or calculator, we can find that the probability of Z being greater than 1.3363 is approximately 0.0918.

Therefore, the probability that the mean blood pressure for a sample of 20 people will be greater than 123 is approximately 0.0918.

Profit is the financial gain obtained by subtracting the cost (or expenses) of producing and selling goods or services from the revenue generated from their sale. In other words, profit is the amount of money that is left over after all expenses have been paid, including the cost of goods sold, operating expenses, taxes, and any other costs associated with running a business.

Profit can be calculated using the following formula:

Profit = Revenue - Cost

To calculate the total purchase price, we need to calculate the tax and add it to the sum of the prices of the diamond necklace and the gold pendant.

The tax on the diamond necklace is:

572.95 * 0.065 = 37.24

The tax on the gold pendant is:

113.76 * 0.065 = 7.40

The total tax is the sum of these two taxes:

37.24 + 7.40 = 44.64

We also need to add the city tax, which is 0.5 percent of the total price:

(572.95 + 113.76) * 0.005 = 3.43

The total purchase price is the sum of the prices of the diamond necklace and the gold pendant, the state tax, and the city tax:

We reject the null hypothesis and come to the conclusion that there is adequate evidence at the 0.02 level.

The rejection of a correct null hypothesis during hypothesis testing is referred to as a Type I mistake. As a result, we get the incorrect conclusion that there is a large difference between two groups or variables. A false positive is another name for a Type I mistake.

Failure to reject a faulty null hypothesis is a Type II mistake. This means that we get the incorrect conclusion that there is no difference between two groups or variables when there actually is one. False negative is another name for a Type II mistake.

The valve generates a mean pressure of 4.7 lbs/square inch, which is the null hypothesis:

H0: μ = 4.7

The other possibility is that the valve does not generate 4.7 lbs/square inch of mean pressure:

Ha: μ ≠ 4.7

Since we are comparing the single sample mean to a known population mean and we are aware of the population variance, we can test this hypothesis using a one-sample t-test. The test statistic is determined by dividing the sample mean (x) by the population mean, the sample size (n), and the population standard deviation (s).

We obtain the following by plugging in the values:

t = (4.6 - 4.7) / (0.9 / √(240))

t = -4.15

Using a two-tailed test and a t-distribution table with 239 degrees of freedom (240 - 1), we can get the crucial t-value as follows:

T critical equals 2.571

We reject the null hypothesis and come to the conclusion that there is adequate evidence at the 0.02 level that the valve does not operate in accordance with specifications since our computed t-value (-4.15), which is in the rejection area (t -2.571 or t > 2.571), falls within this range.

1.I agree with Serena that we can draw the graphs for the other two rockets by shifting the functions. We can use the same equation and just adjust the values of the horizontal and vertical shifts.

2. The equation f(t) = -6t² represents a quadratic function, which has a parabolic shape when graphed. If we apply a transformation to this function, such as a vertical or horizontal shift, the shape of the graph will change accordingly.

3. The term 82.14 likely represents the maximum height achieved by the rocket, since the equation f(t) = -6t² gives the height of the rocket as a function of time. The value of h(t) = 82.14 corresponds to a specific time when the rocket reaches its maximum height.

4. If the second rocket is launched 3 seconds after the first one, the graph of the second rocket will be shifted horizontally by 3 units to the right compared to the graph of the first rocket. This represents a time delay of 3 seconds between the two launches.

5. The equation of the second rocket would be f(t) = -6(t-3)², assuming that the second rocket has the same initial velocity and acceleration as the first rocket but is launched 3 seconds later.

Step-by-step explanation:

a) To calculate the amount that Eric will receive after the 6 years, we need to use the formula for simple interest:

I = P * r * t

Where:

- I is the interest earned

- P is the principal amount (the initial investment)

- r is the interest rate (as a decimal)

- t is the time period (in years)

In this case, Eric invested $10,000 at an interest rate of 8% for 6 years. So we can plug in these values:

I = 10,000 * 0.08 * 6

I = 4,800

The interest earned is $4,800. To find the total amount that Eric will receive after the 6 years, we need to add the interest to the principal:

Total = P + I

Total = 10,000 + 4,800

Total = 14,800

Therefore, Eric will receive $14,800 after the 6 years.

b) The total interest that Eric will earn is already calculated in part a) and it is $4,800.

The inequality that has a dashed boundary line when graphed is:

y > 3x + 1

In mathematics, an inequality is a statement that two quantities are not equal or do not have the same value. In other words, it is a statement that compares two values, expressing that one value is greater than, less than, or not equal to the other value. An inequality is denoted by symbols such as < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to).

In mathematics, a dashed boundary refers to a boundary line that is graphed as a dashed line rather than a solid line. The use of a dashed line is typically used to indicate that the boundary itself is not included in the set of solutions of an inequality or equation.

In the given question,

The inequality that has a dashed boundary line when graphed is:

y > 3x + 1

The reason for this is that when graphed, the boundary line of the inequality y > 3x + 1 is a straight line, but it is dashed instead of solid. This is because the inequality is strict, meaning that the boundary line itself is not included in the set of solutions. On the other hand, if the inequality had been y ≥ 3x + 1, the boundary line would have been a solid line because the inequality is non-strict and includes the boundary line itself as a solution.

The length of the side opposite to the 42 degree angle in the right triangle is approximately 3.4 units.

The angles of a triangle are the angles formed by its sides. The sum of the angles of a triangle is always 180 degrees, which is a fundamental property of this shape. There are different types of triangles, based on their side lengths and angle measures. For example:

A scalene triangle has three sides of different lengths and three different angles.

An isosceles triangle has two sides of equal length and two equal angles.

An equilateral triangle has three sides of equal length and three equal angles.

A right triangle has one angle that measures 90 degrees (a right angle), and the side opposite to it is called the hypotenuse.

Triangles have many important properties and applications in mathematics, physics, and engineering. They can be used to calculate distances, angles, areas, volumes, and many other quantities. Triangles are also used in the construction of buildings, bridges, and other structures, as well as in art, design, and other fields.

We can use the trigonometric ratio of sine to solve for x:

sin(42) = opposite/hypotenuse

sin(42) = x/5

To solve for x, we can multiply both sides by 5 and simplify:

x = 5*sin(42)

x ≈ 3.4 (rounded to the nearest tenth)

Therefore, the length of the side opposite to the 42 degree angle in the right triangle is approximately 3.4 units.

The value of m∠1 is 103°. The solution has been obtained by using the angle sum property.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the three internal angles of a triangle is 180 degrees.

We are given that m∠5 = 142° and m∠4 = 65°.

Since m∠5 and m∠2 lie on a straight line so, they form a linear pair.

So,

⇒ m∠5 + m∠2 = 180°

⇒ 142° + m∠2 = 180°

⇒ m∠2 = 38°

We know that sum of angles of a triangle is 180°.

So,

⇒ m∠3 + m∠4 + m∠2 = 180°

⇒ m∠3 + 65° + 38° = 180°

⇒ m∠3 + 103° = 180°

⇒ m∠3 = 77°

Now, since m∠3 and m∠1 lie on a straight line so, they form a linear pair.

So,

⇒ m∠3 + m∠1 = 180°

⇒ 77° + m∠1 = 180°

⇒ m∠1 = 103°

Based on the image, we can break 9 × 4 into two expressions as 4 groups of 9 or 9 groups of 4. This equals 36.

It should be noted that to break 9 x 4 up into two expressions, you can use the distributive property of multiplication over addition, which states that a(b + c) = ab + ac.

So, we can rewrite 9 x 4 as:

9 x 4 = 9 x (3 + 1)

Using the distributive property, we can expand this expression as:

9 x (3 + 1) = (9 x 3) + (9 x 1)

Simplifying, we get:

9 x 4 = 27 + 9

Therefore, we have broken up 9 x 4 into two expressions: 27 and 9. This will give 36.
