In a certain population, 18% of the people have Rh-negative blood. A blood
bank serving this population receives 95 blood donors on a particular day. Use the normal
approximation for binomial random variable to answer the following: (a) What is the
probability that 15 to 20 (inclusive) of the donors are Rh-negative? (b) What
is the probability that more than 80 of the donors are Rh-positive?

Answers

a) The probability that 15 to 20 (inclusive) of the donors are Rh-negative is 0.5406.

b) The probability that more than 80 of the donors are Rh-positive is 0.0199.

(a) Given that p = 0.18 and q = 0.82

The mean, μ = np = 95 × 0.18 = 17.1

The variance, σ² = npq = 95 × 0.18 × 0.82 = 13.77

Then, the standard deviation σ = √(npq) = √13.77 ≈ 3.71

Using the Normal approximation for binomial distribution, we need to find the probabilities of P(X ≤ 20) and P(X ≤ 14).

P(X ≤ 20) = P(Z ≤ (20 - μ) / σ) = P(Z ≤ (20 - 17.1) / 3.71) = P(Z ≤ 0.78) = 0.7823P(X ≤ 14) = P(Z ≤ (14 - μ) / σ) = P(Z ≤ (14 - 17.1) / 3.71) = P(Z ≤ -0.84) = 0.2005

The required probability is given by;

P(15 ≤ X ≤ 20) = P(X ≤ 20) - P(X ≤ 14) = 0.7823 - 0.2005 = 0.5406

Therefore, the probability that 15 to 20 (inclusive) of the donors are Rh-negative is 0.5406.

b) We are required to find the probability that X > 80.Given that p = 0.82 and q = 0.18

The mean, μ = np = 95 × 0.82 = 77.9

The variance, σ² = npq = 95 × 0.82 × 0.18 = 13.77

Then, the standard deviation σ = √(npq) = √13.77 ≈ 3.71P(X > 80) = P(Z > (80 - μ) / σ) = P(Z > (80 - 77.9) / 3.71) = P(Z > 0.57) = 0.2843

The probability that more than 80 of the donors are Rh-positive is 0.0199.

This is all one question based on the same main theorem

Answers

(a) The main theorem states that the sum of terms in the given sequence satisfies the equation n(n+1)/2 for various values of n.

(b) The induction step theorem for n = 64 states that if the main theorem holds for n = k, it also holds for n = k + 1.

(c) The induction step theorem for n = 583 states that if the main theorem holds for n = k, it also holds for n = k + 1.

(d) The induction step theorem for n = N states that if the main theorem holds for n = k, it also holds for n = k + 1.

(e) The combination of the induction step in (d) and verification of base cases in (a) completes the proof of the main theorem for all positive integers.

(a) The main theorem states that for any positive integer n, the sum of the terms k=1 to n of the sequence n(n+1)/2 is equal to n(n+1)/2.

Illustrating the main theorem for different values of n:

For n = 1: The sum is 1(1+1)/2 = 1, which holds true.

For n = 2: The sum is 2(2+1)/2 = 3, which holds true.

For n = 3: The sum is 3(3+1)/2 = 6, which holds true.

For n = 4: The sum is 4(4+1)/2 = 10, which holds true.

For n = 5: The sum is 5(5+1)/2 = 15, which holds true.

For n = 6: The sum is 6(6+1)/2 = 21, which holds true.

For n = 7: The sum is 7(7+1)/2 = 28, which holds true.

(b) The Induction Step Theorem for n = 64 states that if the main theorem holds for n = k, then it also holds for n = k + 1.

To prove it, assume that the main theorem holds for n = k, i.e., the sum of k terms is k(k+1)/2.

Then, we need to show that the sum of (k+1) terms is (k+1)((k+1)+1)/2 = (k+1)(k+2)/2.

By adding the (k+1)th term to the sum of k terms, we get (k(k+1)/2) + (k+1) = (k+1)(k+2)/2, which is the desired result.

(c) The Induction Step Theorem for n = 583 states that if the main theorem holds for n = k, then it also holds for n = k + 1.

To prove it, assume that the main theorem holds for n = k, i.e., the sum of k terms is k(k+1)/2.

Then, we need to show that the sum of (k+1) terms is (k+1)((k+1)+1)/2 = (k+1)(k+2)/2.

By adding the (k+1)th term to the sum of k terms, we get (k(k+1)/2) + (k+1) = (k+1)(k+2)/2, which is the desired result.

(d) The Induction Step Theorem for n = N states that if the main theorem holds for n = k, then it also holds for n = k + 1.

To prove it, assume that the main theorem holds for n = k, i.e., the sum of k terms is k(k+1)/2.

Then, we need to show that the sum of (k+1) terms is (k+1)((k+1)+1)/2 = (k+1)(k+2)/2.

By adding the (k+1)th term to the sum of k terms, we get (k(k+1)/2) + (k+1) = (k+1)(k+2)/2, which is the desired result.

(e) The proof of the induction step in (d) combined with the verification of several base cases in (a) completes the proof of the Main Theorem because it establishes that the theorem holds for all positive integers. The induction step shows that if the theorem holds for any positive integer, it also holds for the next integer. By verifying the base cases, we ensure that the theorem holds for the initial integers. Therefore, by the principle of mathematical induction, the theorem holds for all positive integers.

Based on the following, should a one-tailed or two- tailed test be used? Họ: H = 17,500 Ha: # 17,500 V = 18,000 s= 3000 n = 10

Answers

The required  correct answer is a two-tailed test should be used based on the following data

Explanation:

To determine whether a one-tailed or two-tailed test should be used based on the following data:              

 H0: H = 17,500Ha: # 17,500V = 18,000s = 3000n = 10                                 We must first examine the alternative hypothesis (Ha) to determine whether it is directional (one-tailed) or non-directional (two-tailed).

A directional alternative hypothesis, or a one-tailed test, is a hypothesis that predicts the direction of the difference between the sample mean and the population mean. Ha: < 17,500 or Ha: > 17,500 are examples of a directional hypothesis.

A non-directional alternative hypothesis, or a two-tailed test, is a hypothesis that does not predict the direction of the difference between the sample mean and the population mean.

Ha: ≠ 17,500 is an example of a non-directional hypothesis.Since Ha: # 17,500 is not directional and does not predict the direction of the difference between the sample mean and the population mean, a two-tailed test is required.

Therefore, a two-tailed test should be used based on the following data.

The double asterisk operator (**) is used to raise the radius to the power of 3, which represents r³ in the formula.

To compute the volume of a sphere, the given formula is used. It is: volume of a sphere = (4.0 / 3.0) πr³ where r is the radius of the sphere.

Therefore, to find the volume of the sphere given the sphere_radius and pi, the formula above is used, as shown below: sphere_volume = (4.0 / 3.0) * pi * sphere_radius**3

where sphere_radius is the given radius of the sphere and pi is the constant pi.

The double asterisk operator (**) is used to raise the radius to the power of 3, which represents r³ in the formula.

Pi (π) is a mathematical constant that represents the ratio of the circumference of a circle to its diameter. It is an irrational number, which means it cannot be expressed as a simple fraction or as a finite decimal. The decimal representation of pi goes on infinitely without repeating.

The value of pi is approximately 3.14159, but it is typically rounded to 3.14 for simplicity in calculations. However, to maintain accuracy, mathematicians and scientists often use more decimal places, such as 3.14159265359, depending on the level of precision required for their calculations.

Answers

A 98% confidence interval for the mean number of books people read is (13.76, 15.84).

The given data is: x = 14.8 books, s = 16.5 books, n = 967. Here, we need to find the 98% confidence interval for the mean number of books people read. Now, we know that the confidence interval can be calculated by the formula:

CI = x ± Z_(α/2) (σ/√n), where Z_(α/2) is the z-score value at α/2 level of significance.

Let's calculate the Z_(α/2):

α = 1 - 0.98 = 0.02

α/2 = 0.02/2 = 0.01

`The area in the right tail will be: 0.01 + 0.98 = 0.99 from the z-table.

Looking at the z-table, the corresponding z-score for 0.99 will be "2.33". So, Z_(α/2) = 2.33

Putting all the values in the formula: CI = 14.8 ± 2.33 (16.5/√967)

Calculating this: CI = 14.8 ± 1.96 (0.53)

So, CI = (13.76, 15.84)

Hence, a 98% confidence interval for the mean number of books people read is (13.76, 15.84). The correct choice is: There is 98% confidence that the population mean number of books road is between 13.76 and 15.84.

The complete journal entry for the first interest payment and bond discount amortization would be:

Interest expense Dr. $165,000

Bond discount amortization Dr. $5,520

Cash Cr. $168,520 (rounded to the nearest dollar)

Firstly, let's determine the amount of bond discount.

Bond discount is the difference between the face value of a bond and the amount at which it is sold. Here, the company received cash of $2,889,599, whereas the face value of the bond is $3,000,000.

So, the bond discount is: Face value of bond - Cash received

= $3,000,000 - $2,889,599

= $110,401

Now, let's journalize the first interest payment and the amortization of the related bond discount. The bond has a semi-annual interest rate of 11%, so the first interest payment is: $3,000,000 × 11% × 1/2

= $165,000

The journal entries would be: Interest expense Dr. $165,000

Bond discount amortization Dr. $2,920 Cash Cr. $168,920 (rounded to the nearest dollar)

The bond discount amortization is calculated using the straight-line method. The total bond discount is $110,401, and it is amortized over the term of the bond, which is 5 years or 10 semi-annual periods.

So, the bond discount amortization per period is:

Total bond discount / Total number of periods= $110,401 / 10

= $11,040.10 (rounded to the nearest cent)

This amount is amortized each period, along with the interest payment. So, the bond discount amortization for the first period is: $11,040.10 / 2

= $5,520.05 (rounded to the nearest cent)

Therefore, the complete journal entry for the first interest payment and bond discount amortization would be:

use the limit comparison test to determine whether the series converges. k^2 2/k^3-7

Answers

The series ∑[(k² + 2)/(k³ - 7)] diverges using the limit comparison test and the series ∑(1/k) is a well-known harmonic series.

To determine the convergence of the series ∑[(k² + 2)/(k³ - 7)], we can use the limit comparison test. Let's compare it with the series ∑(1/k).

First, we need to find the limit of the ratio of the terms of the two series as k approaches infinity:

lim(k→∞) [(k² + 2)/(k³ - 7)] / (1/k)

Simplifying the expression, we get:

lim(k→∞) [(k² + 2)/(k³ - 7)] × (k/1)

Taking the limit as k approaches infinity, we have:

lim(k→∞) [(k² + 2)/(k³ - 7)] × (k/1) = 1

Since the limit is a finite positive value (1), we can conclude that the given series ∑[(k² + 2)/(k³ - 7)] and the series ∑(1/k) have the same convergence behavior.

The series ∑(1/k) is a well-known harmonic series, which diverges. Therefore, by the limit comparison test, the given series ∑[(k² + 2)/(k³ - 7)] also diverges.

Eat your spinach: Six measurements were made of the mineral content (in percent) of spinach, with the following results. It is reasonable to assume that the population is approximately normal. 19.1 20.8 20.8 21.4 20.5 19.7 a. Construct a 95% confidence interval for the mean mineral content. b. Based on the confidence interval, is it reasonable to believe that the mean mineral content of spinach may be greater than 21%? Explain.

Answers

a. The 95% confidence interval for the mean mineral content of spinach can be calculated using the sample data. The formula for the confidence interval is:

Confidence interval = (sample mean) ± (critical value) * (standard deviation / sqrt(sample size))

Using the given data, the sample mean is 20.63 and the standard deviation is 0.676. The critical value for a 95% confidence level can be obtained from the t-distribution table for a sample size of 6 (n-1 degrees of freedom). Calculating the confidence interval using these values gives a range of approximately 19.97% to 21.29%.

b. Based on the 95% confidence interval, the range of the mean mineral content of spinach is between 19.97% and 21.29%. Since this range includes the value of 21%, it is reasonable to believe that the mean mineral content of spinach may be greater than 21%. However, we cannot be certain as the range also includes values below 21%. A larger sample size or narrower confidence interval would provide more precise information about the true mean.

Lines v and w are parallel. If <1 measures 62°, what is the measure of <8?

Answers

The measure of angle 8 is 118°, and the measure of the angle opposite to it, angle 6, is 62°.

If lines v and w are parallel and angle 1 (denoted as <1) measures 62°, then angle 8 (denoted as <8) is supplementary to <1 (since they are corresponding angles on the same side of the transversal line) and thus measures 180 - 62 = 118°.

When two straight lines are cut by a transversal line, corresponding angles on the same side of the transversal are equal. Therefore, <8 and <1 are equal in measure. By transitivity, <8 is also equal in measure to the angle that is opposite it and adjacent to <1, which we could denote as <6.

We can apply the same reasoning to find the measure of angle 6. Since line v is parallel to line w, angle 6 and angle 1 are alternate interior angles, and thus are equal in measure. Therefore, <6 also measures 62°, and this is the measure of the angle opposite to angle 8.

Answer: w+x=90

z=y+90

Step-by-step explanation: because the sum of the inner angles of triangle is 180. given that one angle is 90 degrees the sun of x and w has to be 180-90=90

for the second part, you have to use the triangle exterior angle theorem: an exterior angle of a triangle is equal to the sum of the opposite interior angles. The opposite interior angles in this case is 90 degrees and y
