Bart found 20 quadrilaterals in his classroom. He made a Venn diagram using the properties of the quadrilaterals, comparing those with four equal side lengths (E) and those with four right angles (R). Circles E and R overlap. Circle E contains 3, circle R contains 6, and the intersection contains 2. Number 9 is outside of the circles. Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four equal side lengths? Express your answer in percent form, rounded to the nearest whole percent. 25% 33% 40% 67%

Answers

Answer 1

Answer:

A. 25%

Step-by-step explanation:

Answer 2

The probability that the quadrilateral has four equal side lengths, given that the quadrilateral has four right angles is 25%

What are quadrilaterals?

Quadrilaterals are shapes that have four sides; these four sides may or may not be:

ParallelCongruent

Check below on how to determine the probability

From the question, we have the following parameters:

n(E) = 5n(R) = 8n(E and R) = 2None = 9n(U) = 20

The probability that the quadrilateral has four equal side lengths, given that the quadrilateral has four right angles is calculated using:

P(E | R) = n(E and R)/n(R)

This gives

P(E | R) = 2/8

Express as percentage

P(E | R) = 25%

Hence, the probability is 25%

Answers

The correct option is (a) connectors. The elements that give data on the network a way to move between nodes. This covers network media, connectors, and network interface cards (NIC).

A message is a piece of data sent over the internet, but before a message is sent, it is divided up into smaller pieces called packets. Using Transport Control Protocol (TCP) and Internet Protocol (IP), these messages and packets move between sources (TCP).

The cables (coaxial, twisted pair, fiber optic, and telephone lines) connecting the various network hardware components, the network adapters used by computers connected to the network (hosts), and any concentrators, repeaters, routers, or bridges employed in the network make up the physical network. The term "physical connection" refers to the total number of trunk lines, complete circuits, and connections—including those made by wire, optics, radio signal, or other means—necessary to provide reasonably adequate telecommunications service among telecommunications providers.

What is an arithmetic sequence?

In a Number-crunching Succession, the distinction between one term and the following is steady. Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

The sequence is given below.

0, 10, 18, 25, 33, ...

The difference between two successive terms is given as,

Answers

So the supermarket unit price for 24.0 ounce box is $0.2 and 15.3-ounce box is $0.3

Step-by-step explanation:

It is common that superstores often display units of their choice. That's okay. What you can do is perform some simple calculations to calculate the unit price in whatever unit you want.

For example, here the price for 15.3 ounce box is $4.62

So, the price for 1 box would be

15.3 x 1/15.3 = 4.62 x 1/15.3

1 box = $0.3 (Unit price)

Similarly,

24 = 5.35

24 x 1/24 = 5.23 x 1/24

1 box = $0.2 (Unit price)

The correct options for the linear combinations of the vectors are given by:

A, B, C, D, E and F.

What is a span between two vectors?

The span between two vectors is the set that contains all linear combinations between these two vectors.

Supposing we have two vectors u1 and u2, as is the case in this problem, the infinitely many linear combinations have the following format:

k1u1 + k2u2

In which k1 and k2 are real numbers.

With k1 = 4 and k2 = -7, we get that option A is correct.

For option B, the vector 0 will always be a part of the span, as it can be formed with constants 0, hence it is correct.

The dimension of the span is of 3, as the vectors have 3 elements, hence option C is correct.

The underlying vectors will always also be part of the span, as they can be formed with their constant 1 and the others at 0, hence options D and F are correct.

The size of the span of any vectors is of infinity, hence option E is correct while option G is not.

Distributionally robust stochastic programs with side information based on trimmings

This is a research paper whose authors are Adrián Esteban-Pérez and Juan M. Morales.

Abstract:

We look at stochastic programmes that are conditional on some covariate information, where the only knowledge of the possible relationship between the unknown parameters and the covariates is a limited data sample of their joint distribution. We build a data-driven Distributionally Robust Optimization (DRO) framework to hedge the decision against the inherent error in the process of inferring conditional information from limited joint data by leveraging the close relationship between the notion of trimmings of a probability measure and the partial mass transportation problem.We demonstrate that our technique is computationally as tractable as the usual (no side information) Wasserstein-metric-based DRO and provides performance guarantees. Furthermore, our DRO framework may be easily applied to data-driven decision-making issues involving tainted samples. Finally, using a single-item newsvendor problem and a portfolio allocation problem with side information, the theoretical findings are presented.

Conclusions:

We used the relationship between probability reductions and partial mass transit in this study to give a straightforward, yet powerful and creative technique to expand the usual Wasserstein-metric-based DRO to the situation of conditional stochastic programming. In the process of inferring the conditional probability measure of the random parameters from a limited sample drawn from the genuine joint data-generating distribution, our technique generates judgments that are distributionally resilient to uncertainty. In a series of numerical tests based on the single-item newsvendor issue and a portfolio allocation problem, we proved that our strategy achieves much higher out-of-sample performance than several current options. We backed up these actual findings with theoretical analysis, demonstrating that our strategy had appealing performance guarantees.
