People arrive at a college admissions office at rate 1 per minute, and the arrival is a Poisson process. When k people have arri

Answer:

K=20

Step-by-step explanation:

The question appears to lack any elements of randomness.

An arrival rate of one per minute is constant.

Next, calculate the average expense incurred by each individual to attain a four, which includes the cost of the guide alongside the expense of waiting.

This leads us to K, representing the anticipated number of attendees.

Calculating the waiting time per minute gives

= 1/2(K-1)K.

The tour expense amounts to 20+1/20(K-1).

The cost attributed to each guest equals 20/k +1/20(K-1).

By setting the derivative to zero, we find that

K=20

"Which pairs of angles in the figure below are vertical angles? Check all that apply.
lawyer [4039]
Angles known as vertical angles are those that are located across from each other at a common vertex where two lines intersect.

In the illustration, there exists only one pair of vertical angles.

These are Angle TSW and Angle ISN, both converging at the vertex labeled S.

<span>Answer is: B. Angle ISN and Angle TSW.</span>

Square T was translated by the rule (x + 2, y + 2) and then dilated from the origin by a scale factor of 3 to create square T″.
AnnZ [3900]

Answer: OPTION C.

Step-by-step explanation:

It is essential to consider the following:

Dilation:

  • A transformation where the image retains the same shape as the original but differs in size.
  • Dilation maintains the order of points.
  •  Measurements of angles remain unchanged.

Translation:

  • A transformation that keeps the image identical in size and shape to the original.
  • Translation preserves the ordering of points.
  • The angle measurements do not change.

Consequently, since Square T underwent translation followed by dilation to form Square T'', we conclude that the rationale explaining why they are similar is:

Translations and dilations maintain the order of points; thereby, the corresponding sides of squares T and T″ are proportional.

Use the normal approximation to the binomial distribution to answer this question. Fifteen percent of all students at a large un
AnnZ [3900]

Answer: 0.1289

Step-by-step explanation:

Given: The proportion of students absent on Mondays at a large university.: p=0.15

Sample size: n=12

Mean: \mu=np=12\times0.15=1.8

Standard deviation = \sigma=\sqrt{np(1-p)}

\Rightarrow\ \sigma=\sqrt{12(0.15)(1-0.15)}=1.23693168769\approx1.2369

Let x represent a binomial variable.

Referencing the standard normal distribution table,

P(x=4)=P(x\leq4)-P(x\leq3) (1)

Z score for normal distribution:-

z=\dfrac{x-\mu}{\sigma}

For x=4

z=\dfrac{4-1.8}{1.2369}\approx1.78

For x=3

z=\dfrac{3-1.8}{1.2369}\approx0.97

Thus, from (1)

P(x=4)=P(z\leq1.78)-P(z\leq0.97)\\\\=0.962462-0.8339768\approx0.1289

Consequently, the likelihood of four students being absent = 0.1289

"Our customer retention rate has decreased 10% from last quarter's goal of 250 consumers retained. We need to increase our curre
Zina [3917]

1. Calculate 10% of 250 (250 × 0.10 = 25)
2. Subtract that from 250 (250 - 25 = 225)
3. Then find 16% of 225 (225 × 0.16 = 36)
4. Add 225 and 36 to get 261
5. Therefore, the target number of consumers retained is 261

The total amount of water a tank can hold is 14 and one-half gallons. Raul wants to find out how many 1 and one-fourth-gallon bu
lawyer [4039]

Answer:

The total capacity of the tank is 14 1/2 gallons or 29/2.

The size of bucket is 1 1/4 gallons, equal to 5/4.

The expression representing this situation can be

29/2 divided by 5/4.

Therefore, the number of buckets applied equals 29/2 multiplied by 4/5.
