The area, calculated to three decimal places, is 145.5 square units.

We are given two equations: y = x and y = x² - 3x² - 17x + 12: y = x + 12. To find the area bounded by these two curves, we must first determine the points of intersection between them.To determine the points of intersection:Setting the two equations equal to each other, we get:x = x² - 3x² - 17x + 12: x = x² - 16x + 12: x² - 17x + 12 = 0

Factoring, we get:(x - 1) (x - 16) = 0Thus, x = 1 or x = 16 are the two points of intersection.To find the area bounded by these two curves, we integrate the function (x² - 3x² - 17x + 12) - (x + 12) with respect to x, from x = 1 to x = 16. This gives us the area between the two curves.The area is given by:[∫_1^16 (x²-3x²-17x+12)-(x+12) dx]Now, we can integrate and evaluate from 1 to 16 to get the area. This gives us:(-x³/3 + x²/2 - 16.5x) evaluated from 1 to 16.After evaluation, we get an area of 145.5 square units.

The maximum and minimum values on the curve formed by the intersection of z = 1+2x² +3y² with z = 5−(3x² +5y²) are 9/5 and 7/5 respectively.

The equations of the curve formed by the intersection of z = 1+2x²+3y² with z=5−(3x² + 5y² ) are given by:

1+2x² +3y² = 5−(3x² +5y²)

5x² +8y² =2 ... (Equation 1)

The given equation 5x² +8y² =2 can be written as:

(x/√(2/5))2+(y/√(2/8))2=1 ... (Equation 2)

The given equation in the problem is a two variable equation z=5−(3x² +5y²).

Now, we can find the maximum and minimum values of z on the curve formed by the intersection of z=1+2x² +3y² with z=5−(3x² +5y²) by evaluating z at the endpoints of the major axis of the ellipse given by Equation 2.

A point on the major axis of the ellipse given by Equation 2 can be represented as (x,0).

Substituting y = 0 in Equation 2 and solving for x, we get:

x= ± √(2/5)

So, the endpoints of the major axis of the ellipse given by Equation 2 are (−√(2/5), 0) and (√(2/5), 0).

Substituting these values in Equation 1, we get:

z= 1+2x² +3y² = 1+2(−√(2/5))² +3(0)² = 1+2(2/5) = 9/5

So, the maximum value on the curve formed by the intersection of z = 1+2x² +3y² with z = 5−(3x² +5y²) is 9/5.

To find the minimum value on the curve, we can again substitute the values of x and y from the endpoints of the major axis of the ellipse in the equation z = 1+2x² +3y²

Substituting these values in the equation z = 5−(3x² +5y²), we get:

z= 5−3(−√(2/5))² −5(0)² = 5−3(2/5) = 7/5

So, the minimum value on the curve formed by the intersection of z = 1+2x² +3y² with z = 5−(3x² +5y²) is 7/5.

The maximum and minimum values on the curve formed by the intersection of z = 1+2x² +3y² with z = 5−(3x² +5y²) are 9/5 and 7/5 respectively.

We are 80% confident that the true average number of chocolate chips per Big Chip cookie is between 5.47 and 5.93.

To find the confidence interval for the true mean number of chocolate chips per cookie in all Big Chip cookies, we can use a t-distribution since the sample size is less than 30 and the population standard deviation is unknown.

First, we need to calculate the standard error of the mean (SEM):

SEM = s / sqrt(n) = 1.5 / sqrt(71) ≈ 0.178

where s is the sample standard deviation and n is the sample size.

Next, we can use the t-distribution with n-1 degrees of freedom to find the margin of error (ME) for an 80% confidence level. From a t-distribution table or calculator, we can find that the t-value for 70 degrees of freedom and an 80% confidence level is approximately 1.296.

ME = t-value * SEM = 1.296 * 0.178 ≈ 0.23.

Finally, we can construct the confidence interval by adding and subtracting the margin of error from the sample mean:

CI = sample mean ± ME

= 5.7 ± 0.23

= [5.47, 5.93]

Therefore, we are 80% confident that the true average number of chocolate chips per Big Chip cookie is between 5.47 and 5.93.

The probability of not enough seats being available when Air-USA books 17 persons is 0.17. This probability is not low enough to alleviate concerns for passengers, whether we define unusual as 5% or 10%.

The probability of not having enough seats available when Air-USA books 17 persons can be calculated by considering the percentage of booked passengers who actually arrive for the flight. Since past studies reveal that only 83% of the booked passengers actually arrive, we can calculate the probability as follows:

Probability = 1 - Percentage of passengers who arrive

          = 1 - 0.83

          = 0.17

Therefore, the probability that not enough seats will be available is 0.17.

To determine if this probability is low enough to not be a concern for passengers, we need to compare it with the defined threshold of "unusual" events. If we define unusual as 5% or less, then the probability of 0.17 is higher than the threshold. Therefore, if we define unusual as 5% or less, the probability is not low enough to not be a concern for passengers.

However, if we define unusual as 10% or less, then the probability of 0.17 is still higher than the threshold. Therefore, even with a higher threshold, the probability is still not low enough to not be a concern for passengers.

In conclusion, regardless of whether we define unusual as 5% or 10%, the probability of not enough seats being available is not low enough to alleviate concerns for passengers.

At the 0.05 significance level, the test statistic is x² = 9.395 and the critical value is x² = 7.815. Based on this, there is sufficient evidence to warrant the rejection of the claim that the distribution of crashes conforms to the distribution of ages.

To test the claim that the distribution of crashes conforms to the distribution of ages, we can use a chi-square goodness-of-fit test. This test allows us to compare the observed frequencies (the number of crashes in each age category) to the expected frequencies (the number of crashes we would expect if all age groups had the same crash rate).

First, we calculate the expected frequencies based on the assumption of equal crash rates. We multiply the total number of crashes (290) by the expected proportions for each age category (16%, 44%, 27%, 13%) to obtain the expected frequencies: 46.4, 127.6, 78.3, and 37.7, respectively.

Next, we calculate the test statistic, which measures the discrepancy between the observed and expected frequencies. The formula for the chi-square test statistic is given by:

x² = Σ[(O - E)² / E]

Where O is the observed frequency and E is the expected frequency for each category. By plugging in the values from the table, we calculate the test statistic to be x² ≈ 9.395.

To make a decision about the claim, we compare the test statistic to the critical value from the chi-square distribution. At a 0.05 significance level with three degrees of freedom (four age categories - one for the expected proportions), the critical value is approximately x² = 7.815.

If the test statistic is greater than the critical value, we reject the claim that the distribution of crashes conforms to the distribution of ages. In this case, since the test statistic (9.395) exceeds the critical value (7.815), we have sufficient evidence to warrant the rejection of the claim.

Therefore, based on the given data and the 0.05 significance level, we conclude that there is sufficient evidence to suggest that the distribution of crashes does not conform to the distribution of ages.

The probability of getting more than 6 successes in 15 trials with a probability of success of 0.38 is:

P(X > 6) = 1 - P(X <= 6) = 1 - 0.9603 = 0.0397

To find the probability of getting more than 6 successes in 15 trials with a probability of success of 0.38 using a binomial distribution, we can use the following formula:

P(X > 6) = 1 - P(X <= 6)

where X is the random variable representing the number of successes in 15 trials.

Using the binomial probability formula, we can calculate the probability of getting exactly k successes in n trials with a probability of success p:

P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

where (n choose k) represents the number of ways to choose k successes from n trials.

Using this formula, we can calculate the probability of getting 6 or fewer successes in 15 trials:

P(X <= 6) = Σ [ (15 choose k) * 0.38^k * (1-0.38)^(15-k) ] for k = 0 to 6

We can use a calculator or software to compute this sum, which gives us:

P(X <= 6) = 0.9603

Therefore, the probability of getting more than 6 successes in 15 trials with a probability of success of 0.38 is:

P(X > 6) = 1 - P(X <= 6) = 1 - 0.9603 = 0.0397

I cannot provide the exact indicated first quartile score (x4) in this case.

To find the indicated 1Q (first quartile) score, we need to refer to the graph provided. However, since this is a text-based conversation, I don't have access to or visibility of any visual aid or graph on the right.

Nevertheless, I can explain how to determine the first quartile score using the given information. In a normally distributed data set, the first quartile (Q1) represents the score that separates the lowest 25% of the distribution from the rest.

Given that the mean is 100 and the standard deviation is 15, we can use the properties of the standard normal distribution to find the Z-score corresponding to the first quartile.

The Z-score can be calculated using the formula:

Z = (X - μ) / σ

where X is the score, μ is the mean, and σ is the standard deviation.

Since the first quartile represents the lower 25% of the distribution, the cumulative probability corresponding to the first quartile is 0.25.

Using a Z-table or calculator, we can find the Z-score that corresponds to a cumulative probability of 0.25, which represents the first quartile. This Z-score can then be converted back to the corresponding raw score (X) using the formula above.

ΔP/P = 0, the denominator ΔQ/ΔP becomes undefined.To evaluate the demand elasticity E when P = 40,

we need to calculate the absolute value of the percent change in quantity divided by the percent change in price.

Given that the demand function is Q = 100e^(-0.02p), we can differentiate it with respect to p to find the derivative:

dQ/dp = -0.02 * 100 * e^(-0.02p) = -2e^(-0.02p).

To calculate the percent change in quantity, we need to evaluate the derivative at P = 40:

dQ/dp = -2e^(-0.02*40) = -2e^(-0.8) ≈ -2 * 0.4493 ≈ -0.8986.

Next, we calculate the percent change in price:

ΔP/P = (P2 - P1) / P1 = (40 - 40) / 40 = 0.

Since the percent change in price is zero, we can simplify the formula for elasticity:

E = |(dQ/dp) / (ΔQ/ΔP)|.

Since ΔP/P = 0, the denominator ΔQ/ΔP becomes undefined.

Therefore, we cannot determine the demand elasticity E when P = 40 using the given information.

The numerical limits for a C grade on the test are between approximately 64 and 74.

To find the numerical limits for a C grade, we need to determine the score range that falls below the top 42% of scores and above the bottom 19% of scores.

Given that the scores on the test are normally distributed with a mean of 74.6 and a standard deviation of 9.1, we can use the properties of the normal distribution to calculate the corresponding z-scores.

First, let's find the z-score that corresponds to the top 42% of scores. Using a standard normal distribution table or a calculator, we find that the z-score for the top 42% is approximately 0.17.

Next, we find the z-score that corresponds to the bottom 19% of scores, which is approximately -0.88.

Using these z-scores, we can calculate the corresponding raw scores by applying the formula: raw score = z-score * standard deviation + mean.

For the upper limit of the C grade, we calculate 0.17 * 9.1 + 74.6, which is approximately 76.2. Rounded to the nearest whole number, the upper limit is 76.

For the lower limit of the C grade, we calculate -0.88 * 9.1 + 74.6, which is approximately 64.7. Rounded to the nearest whole number, the lower limit is 65.

Therefore, the numerical limits for a C grade on the test are between approximately 64 and 74.

The correct answer is D. Since the CI was (positive, positive), P1 is higher, this means the proportion of Democrats that voted is higher.

To determine if the proportion of Republicans that vote is higher than the proportion of Democrats that vote, we can use a two-proportion confidence interval.

Let's calculate the confidence interval using the given information:

Proportion of Republicans that voted (p1) = 30/60 = 0.5

Proportion of Democrats that voted (p2) = 30/60 = 0.5

Sample size for both groups (n1 = n2) = 60

We'll use a 95% confidence level for the confidence interval.

Using a two-proportion confidence interval formula, the confidence interval can be calculated as:

CI = (p1 - p2) ± Z * √[(p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)]

where Z is the critical value corresponding to the desired confidence level.

Since the sample sizes for both groups are the same (60), we can simplify the formula:

CI = (p1 - p2) ± Z * √[2 * p * (1 - p) / n]

where p is the pooled proportion, calculated as (p1 + p2) / 2.

p = (0.5 + 0.5) / 2 = 0.5

Next, we need to determine the critical value corresponding to a 95% confidence level. Using a standard normal distribution table, the critical value for a 95% confidence level is approximately 1.96.

Now, let's calculate the confidence interval:

CI = (0.5 - 0.5) ± 1.96 * √[2 * 0.5 * (1 - 0.5) / 60]

CI = 0 ± 1.96 * √[0.5 * 0.5 / 60]

CI = 0 ± 1.96 * √[0.00833]

CI = 0 ± 1.96 * 0.0912

CI ≈ (-0.179, 0.179)

The confidence interval is approximately (-0.179, 0.179). Since the interval includes zero, we cannot conclude that the proportion of Republicans that vote is higher than the proportion of Democrats that vote.

To solve this problem, we can use the binomial distribution to calculate the probability of obtaining at least 2 men with a serum cholesterol level greater than 230 out of 5 randomly selected men.

Let's define success as having a serum cholesterol level greater than 230. The probability of success in a single trial is the probability of a randomly selected man having a serum cholesterol level greater than 230.

To calculate this probability, we need to standardize the value using the given mean and standard deviation. Let's denote this standardized value as Z.

Z = (230 - 178.1) / 40.7 ≈ 1.514

Now, we can use the binomial distribution formula to calculate the probability:

P(X ≥ 2) = 1 - P(X = 0) - P(X = 1)

where X follows a binomial distribution with parameters n = 5 (number of trials) and p (probability of success).

To calculate P(X = 0) and P(X = 1), we can use the binomial probability formula:

P(X = k) = [tex](n choose k) * p^k * (1 - p)^(n - k)[/tex]

where (n choose k) represents the number of combinations of n items taken k at a time.

P(X = 0) = [tex](5 choose 0) * p^0 * (1 - p)^(5 - 0)[/tex]

P(X = 1) = [tex](5 choose 1) * p^1 * (1 - p)^(5 - 1)[/tex]

Now, substitute the values into the formulas:

P(X = 0) = [tex](5 choose 0) * (1 - p)^5[/tex]

P(X = 1) =[tex](5 choose 1) * p * (1 - p)^4[/tex]

Finally, calculate P(X ≥ 2) using the formula:

P(X ≥ 2) = 1 - P(X = 0) - P(X = 1)

Substitute the values and calculate the final probability.

The profit function is calculated by subtracting the cost function from the revenue function. The revenue function is given by R(x) = xp, where x is the number of items produced and p is the price per item. The cost function is given by C(x) = -10x^2 + 250x. The profit function is then given by P(x) = R(x) - C(x).

The profit function can be simplified by using the quadratic formula to solve for the roots of the profit function. The roots of the profit function are x = 169 and x = -125. The maximum profit is achieved when x = 169 items are produced. The maximum profit is $16831. The point of diminishing returns for the profit function is at x = 125 items. This is because the marginal profit is positive for x < 125, negative for x > 125, and zero at x = 125.

We know that,

P(B) = 0.30 and P(B') = 0.70.

Since these are complementary events,

We can find P(A) using the law of total probability,

P(A) = P(AIB) P(B) + P(AIB') P(B')

i) To find the matrix M, we rewrite the system of differential equations in the form dx/dt = Mx, where x(t) = [A(t), B(t), C(t)]^T. By comparing the coefficients, we obtain the matrix M.

ii) By finding the eigenvalues of M, we can determine that two of them can be written as A+ = K ± √(K^2 - W). The constants K and W can be calculated based on the coefficients in the matrix M.

iii) To find the third eigenvalue A3, we solve for the remaining eigenvalue using the characteristic equation det(M - A3I) = 0, where I is the identity matrix.

iv) We can transform the matrix M into a diagonal form by finding a matrix P consisting of the eigenvectors of M and calculating the diagonal matrix D = P^(-1)MP. In the new basis, M will be diagonalized.

The defect rate is given as 1%, which means the probability of an item not having a defect is 99%. By applying this probability to each of the three items and subtracting from 1, we can determine the probability of at least one defect.

The probability of an item not having a defect is 99% or 0.99. Since the items are chosen independently, the probability of all three items not having a defect is obtained by multiplying the probabilities for each item: 0.99 * 0.99 * 0.99 = 0.970299.

This represents the complementary probability of none of the items having a defect. To find the probability of at least one defect, we subtract this value from 1: 1 - 0.970299 = 0.0297. Therefore, the probability that at least one item will have a defect is approximately 0.0297 or 2.97% when rounded to four decimal places.

The two curves intersect at x = 2, we can now evaluate the area enclosed by the curves as follows:∫02 g(x) − f(x) dx= ∫02 x7 − 2x6 dx= [x8/8 − 2x7/7]2 0= 128/8 − (2(128/7))/7= 16 − 32/7= 96/7The area enclosed by the curves f(x) = 2x6 and g(x) = x7 is 96/7 square units

The curves f(x) = 2x6 and g(x) = x7 encloses the region between the x-axis and the curves.

To find the area enclosed by the curves, we need to evaluate the definite integral of the difference between the curves over their common interval of interest.

We first need to find the points of intersection of the two curves. Setting the two curves equal to each other gives:2x6 = x7⇔ 2 = x.

Since the two curves intersect at x = 2, we can now evaluate the area enclosed by the curves as follows:∫02 g(x) − f(x) dx= ∫02 x7 − 2x6 dx= [x8/8 − 2x7/7]2 0= 128/8 − (2(128/7))/7= 16 − 32/7= 96/7The area enclosed by the curves f(x) = 2x6 and g(x) = x7 is 96/7 square units

To find the area enclosed by two curves, we must find the points of intersection between the curves and then evaluate the definite integral of the difference between the curves over their common interval of interest.In this problem, the two curves are f(x) = 2x6 and g(x) = x7.

To find the points of intersection between the curves, we set the two curves equal to each other and solve for x:2x6 = x7⇔ 2 = x.

Thus, the two curves intersect at x = 2. We can now evaluate the area enclosed by the curves using the definite integral:∫02 g(x) − f(x) dx= ∫02 x7 − 2x6 dx= [x8/8 − 2x7/7]2 0= 128/8 − (2(128/7))/7= 16 − 32/7= 96/7

Therefore, the area enclosed by the curves f(x) = 2x6 and g(x) = x7 is 96/7 square units. In conclusion, we found that the two curves intersect at x = 2 and used this information to evaluate the definite integral of the difference between the curves over their common interval of interest. The area enclosed by the curves is 96/7 square units.

f(x) = 6e-2x

f'(x) = -12e-2x

y = 8xe^(8x)

y' = 8(1 + 8x)e^(8x)

To differentiate these functions, we can use the following rules:

The derivative of a constant is 0.

The derivative of e^x is e^x.

The derivative of a product is the product of the two functions, multiplied by the derivative of the first function.

The derivative of a quotient is the quotient of the two functions, multiplied by the difference of the two functions raised to the power of the negative one.

In 15), the only term in the function is 6e^(-2x). The derivative of 6 is 0, and the derivative of e^(-2x) is -2e^(-2x). Therefore, the derivative of f(x) is -12e^(-2x).

In 16), the function is a product of two functions: 8x and e^(8x). The derivative of 8x is 8, and the derivative of e^(8x) is e^(8x). Therefore, the derivative of y is 8(1 + 8x)e^(8x).

Using Fermat's little theorem and considering the expression n = 2^(p-2) + 2 * 5^(p-2) + 10^(p-2) - 1, it can be proven that n is a multiple of a prime number p if and only if p is congruent to 2 or 5 modulo p.

Fermat's little theorem states that if p is a prime number and a is an integer not divisible by p, then a^(p-1) is congruent to 1 modulo p. We will use this theorem to prove the given statement.

Consider the expression n = 2^(p-2) + 2 * 5^(p-2) + 10^(p-2) - 1. We want to show that n is a multiple of p if and only if p is congruent to 2 or 5 modulo p.

First, assume that p is congruent to 2 or 5 modulo p. In this case, we can rewrite the expression n as (2^(p-1) - 1) + (2 * 5^(p-1) - 1) + (10^(p-1) - 1). Using Fermat's little theorem, each term in parentheses is congruent to 0 modulo p. Therefore, n is a multiple of p.

Now, assume that n is a multiple of p. We can rewrite n as (2^(p-2) - 1) + (2 * 5^(p-2) - 1) + (10^(p-2) - 1). Since n is a multiple of p, each term in parentheses must also be a multiple of p. This implies that 2^(p-2) - 1, 2 * 5^(p-2) - 1, and 10^(p-2) - 1 are all multiples of p. From Fermat's little theorem, we know that 2^(p-1) and 5^(p-1) are congruent to 1 modulo p. Therefore, 2^(p-2) and 5^(p-2) are also congruent to 1 modulo p. This means that p is congruent to 2 or 5 modulo p.

Hence, using Fermat's little theorem, it is proven that n is a multiple of p if and only if p is congruent to 2 or 5 modulo p.

The values of 'a' for which all solutions of the given differential equation tend to zero as t approaches zero are a ∈ (-∞, 0) ∪ (4, ∞).

On the other hand, the values of 'a' for which all nonzero solutions become unbounded as t approaches infinity are a ∈ (0, 4).

To determine the values of 'a' for which all solutions tend to zero as t approaches zero, we need to analyze the behavior of the differential equation near t = 0. By studying the characteristic equation associated with the differential equation, we find that the roots are given by r = 2 and r = a. For the solutions to tend to zero as t approaches zero, we require the real parts of the roots to be negative. This condition leads to a ∈ (-∞, 0) ∪ (4, ∞).

To determine the values of 'a' for which all nonzero solutions become unbounded as t approaches infinity, we again examine the characteristic equation. The roots are given by r = 2 and r = a. For the solutions to become unbounded as t approaches infinity, we need at least one of the roots to have a positive real part. Therefore, the values of 'a' that satisfy this condition are a ∈ (0, 4).

In summary, the values of 'a' for which all solutions tend to zero as t approaches zero are a ∈ (-∞, 0) ∪ (4, ∞), and the values of 'a' for which all nonzero solutions become unbounded as t approaches infinity are a ∈ (0, 4).

The percentage change in multifactor productivity is approximately 36.15%.

To calculate the percentage change in multifactor productivity, we need to compare the productivity before and after the improvement in the production process. The multifactor productivity is calculated by dividing the output value by the input value.

Given data for the old process:

Number of workers: 11

Output per hour: 4,873 units

Materials cost per unit: $56

Worker wage per hour: $17

Selling price per unit: $102

Given data for the improved process:

Materials cost reduction per unit: $14

Workers reduced: 3

Let's calculate the multifactor productivity before and after the improvement:

Before the improvement:

Output value = Output per hour * Selling price per unit = 4,873 * $102 = $497,046

Input value = (Number of workers * Worker wage per hour) + (Materials cost per unit * Output per hour) = (11 * $17) + ($56 * 4,873) = $5,661 + $272,488 = $278,149

Multifactor productivity before = Output value / Input value = $497,046 / $278,149 ≈ 1.785

After the improvement:

Output value remains the same = $497,046

Input value = [(Number of workers - Workers reduced) * Worker wage per hour] + [(Materials cost per unit - Materials cost reduction per unit) * Output per hour]

= [(11 - 3) * $17] + ($42 * 4,873) = $119 + $204,666 = $204,785

Multifactor productivity after = Output value / Input value = $497,046 / $204,785 ≈ 2.43

Now, let's calculate the percentage change in multifactor productivity:

Percentage change = ((Multifactor productivity after - Multifactor productivity before) / Multifactor productivity before) * 100

= ((2.43 - 1.785) / 1.785) * 100

= (0.645 / 1.785) * 100

≈ 36.15

Therefore, Multifactor productivity has changed by about 36.15 percent.

The total product cost for last month is $12,000, and the unit product cost is $3.

Martinez Manufacturing Inc. incurred various costs last month, including direct materials, direct labor, manufacturing overhead, and selling expense. The task is to classify each cost as either a product cost or a period cost, calculate the total product cost for last month, and determine the unit product cost.

Classifying costs:

Direct materials and direct labor are both considered product costs as they are directly related to the production of goods.

Manufacturing overhead is also a product cost as it includes indirect costs incurred in the manufacturing process.

Selling expense is a period cost since it is associated with selling and distribution activities.

Total product cost:

The total product cost is the sum of all product costs, which in this case includes direct materials, direct labor, and manufacturing overhead. Therefore, the total product cost for last month is $7,000 (direct materials) + $3,000 (direct labor) + $2,000 (manufacturing overhead) = $12,000.

Unit product cost:

The unit product cost is calculated by dividing the total product cost by the number of units produced. In this case, since 4,000 units were produced and sold, the unit product cost for last month is $12,000 (total product cost) / 4,000 (units) = $3 per unit.

Therefore, the total product cost for last month is $12,000, and the unit product cost is $3.

To rationalize the numerator of the expression √5 + 2√2 / 3√10, we need to eliminate any radicals in the numerator by multiplying both the numerator and denominator by an appropriate conjugate. The rationalized numerator of the expression √5 + 2√2 / 3√10 is -3.

The conjugate of √5 + 2√2 is √5 - 2√2. Multiplying the numerator and denominator by the conjugate, we get:

[(√5 + 2√2) * (√5 - 2√2)] / [3√10 * (√5 - 2√2)]

Expanding the numerator and denominator using the distributive property, we have:

[(√5 * √5) + (√5 * -2√2) + (2√2 * √5) + (2√2 * -2√2)] / [3√10 * √5 - 3√10 * 2√2]

Simplifying further, we get:

[5 - 4√10 + 4√10 - 4(2)] / [3√10 * √5 - 3√10 * 2√2]

The terms with √10 cancel each other out, and the terms without radicals simplify:

[5 - 8] / [3√10 * √5 - 6√10]

The final simplified form of the numerator is:

-3 / [3√10 * √5 - 6√10]

Therefore, the rationalized numerator of the expression √5 + 2√2 / 3√10 is -3.
