Answer:

see explanation

Step-by-step explanation:

sum the parts of the ratio, 2 + 1 = 3 parts , thus

81 cm² ÷ 3 = 27 cm² ← value of 1 part of the ratio

2 parts = 2 × 27 = 54 cm²

Area of A = 54 cm² and area of B = 27 cm²

The side of the original square = \sqrt{81} = 9 cm

The width of both rectangles is 9 cm ( width remains unchanged after cut )

Thus

Rectangle A

9 × length = 54 ( divide both sides by 9 )

length = 6 cm

Rectangle B

9 × length = 27 ( divide both sides by 9 )

length = 3 cm

Rectangle A → length = 6 cm, width = 9 cm

Rectangle B → length = 3 cm , width = 9 cm

Answer:

<u>Rectangle A</u>                 <u>Rectangle B</u>

length = 9 cm                length = 9 cm

width = 6 cm                  width = 3 cm

Step-by-step explanation:

Area of square At = 81 cm²

Square is cut into two pieces = A + B

The ration of area A to B = 2:1

Find

Rect A        Rect B

length         length

width           width

---------------------------------

first, get the side of the square = A = s²

81 = s²,      

s = √81      

s = 9 cm

since the ratio is 2:1, therefore the side can be divided into 3

9 ÷ 3 = <u>3 cm </u> ----- take note of this to get the <u>Width</u>

<u>Rectangle A</u>

L = 9 cm (which is the s = 9 cm)

W = <u>3 cm</u> (2 ratio) = 6 cm

<u>Rectangle B</u>

L = 9 cm  (which is the s = 9 cm)

W = <u>3 cm</u> (1 ratio) = 3 cm

<u>Proof:</u>

At = A + B

81 = (9x6) + (9x3)

81 = 54 + 27

81 = 81  ----- OK

Instructions: Find the volume of each figure. Round your answers to the nearest tenth, if necessary.
Ilia_Sergeevich [38]

The volume of the cone is  84.9 km³

<h3>How to find the volume of a cone?</h3>

Volume of a cone = 1 / 3 πr²h

where

  • h = height
  • r = radius

Therefore,

radius = 3 km

height = √9.5² - 3²

height = √81.25

height = 9.01387818866

height = 9.014 km

Volume of a cone = 1 / 3 × 3.14 × 3² × 9.014

volume of the cone = 254.732197612 / 3

volume of the cone = 84.9107325372

volume of the cone = 84.9 km³

Your firm has a new strategy that will make its established product obsolete. However, it will take a year before you are ready
pogonyaev

Answer:

The transition between launching a new product or strategy and discontinuing the current product is a crucial business decision because it involves financial risk, customer relation and overall brand of the organization.

Step-by-step explanation:

I would choose to announce the new business strategy with a risk of short-term financial loss because of the following reasons:-

Competitive Business Environment:- In a competitive world, an organization must update the current line of products or introduce a new one to meet the growing demand and expectations of its customers. Even though a new strategy or product may incur additional cost or a loss, product development is key to having an edge over its competitors.

 Long-Term Goal:- Organizations that develop strategies keeping the long-term vision of the company in mind tend to survive and sustain profits in the long run. Business is an on-going process so it’s important to stay relevant to customer demands in the future as well. Loyal customers always expect the company to deliver new products and services which can outperform the existing products and creates brand loyalty.

Business Integrity:- An organization must exercise effective stakeholder’s relationship management not just with customers but with other stakeholders like suppliers and shareholders. Announcing a new business strategy in advance built trusts and opportunities for your stakeholders to engage with you in a B2B partnership in future. This strengthens the existing partnerships and relations, where others would want to continue doing business with you in future and beyond.

A store randomly samples 603 shoppers over the course of a year and finds that 142 of them made their visit because of a coupon
fiasKO [112]

Answer:

The 95% confidence interval for the fraction of all shoppers during the year whose visit was because of a coupon they'd received in the mail is (0.2016, 0.2694).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the z-score that has a p-value of 1 - \frac{\alpha}{2}.

A store randomly samples 603 shoppers over the course of a year and finds that 142 of them made their visit because of a coupon they'd received in the mail.

This means that n = 603, \pi = \frac{142}{603} = 0.2355

95% confidence level

So \alpha = 0.05, z is the value of Z that has a p-value of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2355 - 1.96\sqrt{\frac{0.2355*0.7645}{603}} = 0.2016

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2355 + 1.96\sqrt{\frac{0.2355*0.7645}{603}} = 0.2694

The 95% confidence interval for the fraction of all shoppers during the year whose visit was because of a coupon they'd received in the mail is (0.2016, 0.2694).
