Let the amount of Tilapia bought be "t" and the amount of Salmon bought be "s"

Since Tilapia costs $3 per pound and Salmon costs $5 per pound, we can say:

Cost of Tilapia = 3t

Cost of Salmon = 5s

Their total cost = 3t + 5s

This total cost should be equal to the total budget, which is $210.

To determine whether the ratios 2/5 and 8/20 are equivalent, we'll convert them both to simplest terms and compare them. In addition, we'll use cross-multiplication to ensure that the fractions are equal.

2/5 can be simplified to simplest terms by dividing both the numerator and denominator by their highest common factor (HCF), which is 1. As a result, 2/5 in its simplest form is written as 2/5.

To simplify 8/20 to simplest terms, we must first determine the highest common factor of 8 and 20. The HCF of 8 and 20 is 4, which is the highest common factor.

We can reduce the fraction by dividing both the numerator and denominator by 4, resulting in 2/5.2/5 and 2/5 are equivalent to one another since they have the same numerator and denominator, implying that the ratios 2/5 and 8/20 are equivalent.

Because the numerators and denominators of these two fractions are both divisible by 2, we know that 2/5 and 8/20 are equivalent. As a result, the ratios 2/5 and 8/20 are equivalent. In conclusion, both ratios are equal since they are equivalent and are the same.

The equation of the curve can be determined by integrating the given property, which states that the slope of the curve at every point is three times the x-coordinate.

To find the equation, we start by integrating the slope property. Integrating the derivative of y with respect to x gives us y = 3x^2 + C, where C is the constant of integration.

Next, we use the given information that the curve passes through a specific point, which means that when x is a certain value, y will be a specific value as well. By substituting the x and y values of the point into the equation, we can solve for the constant of integration, C.

Once C is determined, we can write the final equation of the curve, which will be y = 3x^2 + C. This equation represents the curve that passes through the given point and has the property that the slope at every point is three times the x-coordinate.

After selling 200 copters, Hover-high Helicopters would have a profit of $9.40 per unit. Therefore, the correct answer is d) $9.40 per unit.

To calculate the profit per unit, we need to consider the profit from each unit sold and subtract the cost of any defective units returned for repair.

Hover-high Helicopters has a defect rate of 1 in 100, which means that 1% of the units built are expected to be defective. With 200 copters sold, we can expect 2 units to be returned for repair (200 * 1% = 2).

For each unit sold, Hover-high Helicopters earns a profit margin of $10. However, they incur a cost of $50 for each defective unit returned for repair.

Profit per unit = Profit margin - Cost of defective units

= $10 - ($50 * Number of defective units)

Since 2 units are expected to be defective, the cost of defective units is $50 * 2 = $100.

Profit per unit = $10 - $100 = -$90.

However, the question asks for the profit per unit, so we need to consider the overall profit after selling 200 copters.

Profit per unit after selling 200 copters = Overall profit / Number of units sold

= (-$90 * 2 + $10 * 200) / 200

= ($-180 + $200) / 200

= $20 / 200

= $0.10

Therefore, the profit per unit after selling 200 copters is $0.10, which is equivalent to $9.40 per unit. The correct answer is d) $9.40 per unit.

On solving the question, unit rate by using the given graph could be 2.4 potatoes/pound

Graph can be defined as the visual representation which is used to represent the data.

The unit rate is the slope of the line.

The slope of the line =  (change in y-value)/(change in x-value)

= (36 potatoes - 12 potatoes)/(15 pounds - 5 pounds)

= (24potatoes)/(10 pounds)

= 2.4 potatoes/pound

The relationship here is proportional, so the line goes through the point (0, 0) and the unit rate can be figured from any point:

(12 potates)/(5 pounds)

= (24 potatoes)/(10 pounds)

= (36 potatoes)/(15 pounds) = 2.4 potatoes/pound

Hence, The unit rate by using the given graph could be 2.4 potatoes/pound .

Base layer = 12 in x 10 in x 4 in

Second layer = 3 in smaller x 4 in

Volume = ?

Formula

Total volume = Volume of the base layer + Volume of the second layer

Total volume = length 1 x width 1 x height +  length 2 x width 2 x height

Substitution

Total volume = 12 x 10 x 4 + (12 - 3)(10 - 3)(4)

Simplification

Total volume = 480 + (9)(7)(4)

Total volume = 480 + 252

Total volume = 732 in³

To find two divergent series, summation from n equals 1 to infinity of a_n and summation from n equals 1 to infinity of b_n, such that their product converges, we can consider the following series:

1. Summation from n equals 1 to infinity of a_n = ∑(1/n)
2. Summation from n equals 1 to infinity of b_n = ∑n

Solution:

1. The first series, ∑(1/n), is known as the harmonic series. It is a famous example of a divergent series, meaning that its sum approaches infinity as n approaches infinity.

2. The second series, ∑n, is an arithmetic series where the terms increase linearly. This series is also divergent, as the sum increases without bound as n approaches infinity.

Now, we need to verify that the product of these series converges:

3. Summation from n equals 1 to infinity of (a_n * b_n) = ∑((1/n) * n)

4. Simplifying the expression, we get ∑(1), which is a constant series with all terms equal to 1.

5. The sum of the constant series converges, as it approaches a finite value when n approaches infinity.

In conclusion, the two divergent series summation from n equals 1 to infinity of a_n = ∑(1/n) and

summation from n equals 1 to infinity of b_n = ∑n, have a product that converges, as their product ∑((1/n) * n) simplifies to a constant series ∑(1), which has a finite sum.

In a Chi-square analysis, one rejects (or fails to accept) the null hypothesis when the calculated Chi-square test statistic (χ²) is greater than the critical value, indicating that there is a significant difference between the observed and expected frequencies.

In a chi-square analysis, the null hypothesis is that there is no significant difference between the observed frequencies and the expected frequencies.

The expected frequencies are usually calculated assuming a specific distribution or model.

To determine whether to reject or fail to accept the null hypothesis, we compare the calculated chi-square statistic to a critical value obtained from a chi-square distribution table with a specified degrees of freedom.

The degrees of freedom are calculated as (number of categories - 1).

If the calculated chi-square value is greater than the critical value, it means that the observed frequencies differ significantly from the expected frequencies and that the null hypothesis can be rejected at a certain level of significance (usually 0.05 or 0.01).

In other words, if the chi-square statistic is larger than the critical value, it suggests that the observed data is unlikely to have arisen by chance, and that there is evidence to support the alternative hypothesis, which states that there is a significant difference between the observed and expected frequencies.

On the other hand, if the calculated chi-square value is less than or equal to the critical value, it means that there is no significant difference between the observed and expected frequencies and that the null hypothesis cannot be rejected.

This typically occurs when the p-value associated with the test statistic is less than the predetermined significance level (α), such as 0.05 or 0.01, suggesting that the observed result is unlikely to have occurred by chance alone.

The answer is option (C), that is, the events of rolling a fair die two times are independent. The events are neither disjoint nor exclusive.

When rolling a fair die two times, one can get any one of the 36 possible outcomes equally likely. Let A be the event of obtaining an even number on the first roll and let B be the event of getting a number greater than 3 on the second roll. Let’s see how the outcomes of A and B are related:

There are three even numbers on the die, i.e. A={2, 4, 6}. There are four numbers greater than 3 on the die, i.e. B={4, 5, 6}. So the intersection of A and B is the set {4, 6}, which is not empty. Thus, the events A and B are not disjoint. So option (A) is incorrect.

There is only one outcome that belongs to both A and B, i.e. the outcome of 6. Since there are 36 equally likely outcomes, the probability of the outcome 6 is 1/36. Now, if we know that the outcome of the first roll is an even number, does it affect the probability of getting a number greater than 3 on the second roll? Clearly not, since A∩B = {4, 6} and P(B|A) = P(A∩B)/P(A) = (2/36)/(18/36) = 1/9 = P(B). So the events A and B are independent. Thus, option (C) is correct. Neither option (A) nor option (C) can be correct, so we can eliminate options (D) and (E).

Answer:

First Option {-2 , 0 , 2}

Step-by-step explanation:

A critical point occurs when the derivative is 0 or undefined.

The function in the question is undefined at x = 2 and at x = -2 because if we put x = 2 or x = -2 the denominator becomes 0 hence anything divided by 0 is undefined, and the derivative equals 0 at x = 0 so the critical points are

{-2 , 0 , 2}

Use the quotient rule to find the derivative of the function then equal it to zero
