Answer:

  184.25 kg

Step-by-step explanation:

25% more is found by adding 25% of the original value to the original value. It is equivalent to multiplying the original value by (1 +25%) = 1.25.

__

25% of Roberto's yield is ...

  147.4 kg × 0.25 = 36.85 kg

If Roberto's yield increases by that amount, it will be ...

  147.4 kg + 36.85 kg = 184.25 kg

Roberto should expect a yield of 184.25 kg.

Answer:

184.25

Step-by-step explanation:

The equation of the tangent line to the ellipse at the point (5, -1) is 10x + 2y = 5.

To find the equation of the tangent line to the ellipse, we can use implicit differentiation. Implicit differentiation allows us to find the derivative of a function even if it is not explicitly expressed in terms of a single variable. In this case, the equation of the ellipse is given by \(x^2/10 + y^2/2 = 3\).

To differentiate the equation implicitly, we differentiate each term of the equation with respect to x. For the term x^2/10, we apply the power rule, which states that the derivative of x^n with respect to x is\(nx^(n-1).\) Therefore, the derivative of x^2/10 with respect to x is (2/10)x^(2-1), which simplifies to x/5. Similarly, for the term y^2/2, the derivative with respect to x is 0, since y is treated as a constant.

After differentiating, we substitute the x-coordinate (5) and the y-coordinate (-1) of the given point into the derived equation. This allows us to determine the slope of the tangent line at that specific point. Substituting x = 5 and y = -1 into the equation x/5 + 0 = 0 gives us (5/5) + 0 = 1.

Simplifying the equation further, we obtain the slope-intercept form of the equation. We rewrite the derived equation as 10x + 2y = 5. This is the equation of the tangent line to the ellipse at the point (5, -1).

In conclusion, by utilizing implicit differentiation, we were able to find the equation of the tangent line to the ellipse at the point (5, -1). The equation of the tangent line is given by 10x + 2y = 5.

An MIS differs from a TPS in that it creates databases is True.

An MIS (Management Information System) does indeed differ from a TPS (Transaction Processing System) in that it creates databases. The main purpose of an MIS is to collect, process, store, and disseminate information to support managerial decision-making within an organization. It involves the use of technology and various information systems to manage and analyze data for strategic planning, monitoring, and control.

One of the key components of an MIS is the creation and management of databases. Databases are structured collections of data that are organized, stored, and accessed in a systematic way. They serve as a central repository for storing relevant information that can be utilized by the MIS. These databases can contain data from various sources within the organization, such as sales records, customer information, inventory data, financial data, and more.

On the other hand, a TPS focuses primarily on the processing of transactions. It is designed to capture, process, and record day-to-day operational transactions, such as sales transactions, inventory updates, customer orders, and so on. While a TPS may store and retrieve data related to these transactions, its main focus is on efficiently processing and ensuring the accuracy and integrity of transactional data.

In summary, an MIS goes beyond the functionalities of a TPS by not only processing transactions but also creating and managing databases to support the informational needs of managers.

Answer:

Im not sure

Step-by-step explanation:

Let:

x = Pounds of walnuts in the mix.

Each pound of walnuts costs $0.80. thus x pounds of walnuts cost 0.8x dollars.

Each pound of cashews costs $1.25 and the mix will contain 8 pounds of cashews, so the cost is 8*$1.25 = $10

The total cost of the mix is, therefore: 0.8x + 10 dollars.

We are also given the pound of mix costs $1.00 and we have a total of 8 + x pounds, so the total cost of the mix is 1*(8 + x) dollars.

Equating both costs:

0.8x + 10 = 1*(8 + x)

Operating:

0.8x + 10 = 8 + x

Subtracting x and 10:

0.8x - x = 8 - 10

Simplifying:

-0.2x = -2

Dividing by -0.2:

x = -2/(-0.2)

x = 10

Answer: 10 pounds

Answer:

C. 2.75x + 2.50 ≤ 12

Explanation:

The cost of 1 hotdog = $2.75

Therefore, the cost of x hotdogs = $2.75x

Stacey also bought a bottle of water for $2.50.

Thus, the total amount Stacey spent will be:

Since she did not spend more than $12, it means:

She spent less than or exactly $12.

Thus, the inequality is:

The correct choice is C.

Part 1: Kate should buy 100 coats to maximize profits.Part 2: The probability that the coats sell out is 0.25 (25%), and the probability that they do not sell out is 0.75 (75%).

To maximize profits, Kate should consider the scenario where she sells all the coats without any left over at the end of the season.

Since the sales are uniformly distributed between 100 and 400, buying 100 coats ensures that she meets the minimum expected sales of 100. Purchasing more than 100 coats would increase costs without a guarantee of higher sales, potentially leading to excess inventory and lower profits.

Given that the sales are uniformly distributed between 100 and 400 coats, Kate's purchase of 100 coats covers the minimum expected sales.

The probability of selling out can be calculated by finding the proportion of the range covered by the desired sales (100 out of 300). Therefore, the probability of selling out is 100/300 = 0.25 or 25%. The probability of not selling out is the complement, which is 1 - 0.25 = 0.75 or 75%.

The solution set {(-4, 2)} is satisfied when C = 3 and D = -4. Hence, the correct answer is option C.

To find the values of C and D that satisfy the given system of equations, we substitute the coordinates of the solution set {(-4, 2)} into the equations and solve for C and D.

Substituting x = -4 and y = 2 into the first equation, we have:

C(-4) - 2(2) = -16

-4C - 4 = -16

-4C = -12

C = 3

Next, substituting x = -4 and y = 2 into the second equation, we have:

2(-4) + D(2) = -16

-8 + 2D = -16

2D = -8

D = -4

Therefore, the values of C and D that satisfy the system of equations and yield the solution set {(-4, 2)} are C = 3 and D = -4. Thus, the correct answer is option c: C = 3, D = -4.

Distance between the center and fixed point = radius

\(\sqrt{(h-s)^{2} +(t-b)^{2} }\) = a

The alternative hypothesis (Ha) is that the proportion of those who are adequately prepared financially for retirement is smaller for people in the 66-69 age group who did not complete high school than it is for the population of the 66-69-year-old.

b. To calculate the p-value for this hypothesis test, we can use a one-sample proportion test. The sample proportion (p-hat) is 165/300 = 0.55. Using a z-test, with a z-score of -2.35 and a standard deviation of 0.058, the p-value is 0.011.

c. At a significance level of 0.01, the p-value of 0.011 is less than the significance level, so we reject the null hypothesis.

Given the inverse demand function p = 100 - 20q for toasters and a price of $35, we can find the consumer surplus.

First, we'll find the quantity demanded at the given price:

35 = 100 - 20q
20q = 100 - 35
q = (100 - 35) / 20
q = 65 / 20
q = 3.25

Now, to find the consumer surplus, we'll use the formula:

Consumer Surplus = (1/2) × Base × Height

The base represents the quantity (q = 3.25) and the height is the difference between the maximum willingness to pay (p = 100) and the actual price (p = 35).

Consumer Surplus = (1/2) × 3.25 × (100 - 35)
Consumer Surplus = 0.5 × 3.25 × 65
Consumer Surplus = 105.625

So, the consumer surplus is $105.63 when rounded to two decimal places.
