The volumes of two bodies are measured to be

V₁ = (10.2 ± 0.02) cm³ and V₂ = (6.4 ± 0.01) cm³. Calculate sum and difference in

volumes with error limits.​

Answers

Answer 1

Answer:

Sum of volumes = (16.6 ± 0.03) cm³

Difference of volumes = (3.8 ± 0.03) cm³

Step-by-step explanation:

Solution

V₁ = (10.2 ± 0.02) cm³ and V₂ = (6.4 ± 0.01) cm³.

∆V = ± (∆V₁ + ∆V₂)

= ± (0.02 + 0.01) cm³

= ± 0.03 cm³

V₁ + V₂ = (10.2 + 6.4) cm³ = 16.6 cm³ and

V₁ - V₂ = (10.2 - 6.4) cm³ = 3.8 cm³

Hence, sum of volumes = (16.6 ± 0.03) cm³

and difference of volumes = (3.8 ± 0.03) cm³

Step-by-step explanation:

24 swimmers are swimming in the pool. 9 of them are female. What fraction of swimmers are male?

Answers

Answer:

15/24 or 5/8

Step-by-step explanation:

Well 9 are female

The rest of the 24 has to be male so

24-9=15

15/24 or 5/8

The fraction of male swimmers is 5/8.

Given,

24 swimmers are swimming in the pool.

9 of them are female.

We need to find what fraction of male swimmers.

How do we find fraction of items from the total items?

We write in two parts numerator and denominator.

= Numerator / Denominator

= Number of required items / Total number of items

Find the total number of swimmers.

= 24

Find the number of male swimmers.

= Total swimmers - Female swimmers

= 24 - 9

= 15

Find the fraction of male swimmers.

= Number of male swimmers / Total number of swimmers
= 15 / 24

Taking out the common factor

= 3 x 5 / 3 x 8

= 5/8

Thus the fraction of male swimmers is 5/8.

C. Raise money
D. Get unlimited liability

Answers

Answer:

C

Step-by-step explanation:

The primary objective of an IPO is to raise capital for a business. It can also come with other advantages. The company gets access to investment from the entire investing public to raise capital.

The purpose of an initial public offering (IPO) is to raise money. It could potentially have other benefits, hence option C is correct.

The corporation can raise money by accepting investments from the whole investing public. An IPO's main goal is to help businesses raise finance.

An initial public offering (IPO) is the process of selling new shares of a private company to the public. To hold an IPO, businesses must satisfy Securities and Exchange Commission (SEC) and exchange standards.

Company insiders may use an IPO to diversify their holdings or generate liquidity by selling all or a portion of their private shares as part of the public offering.

Using the following data set calculate the mean 9,14,14,9,20,6,8,19,17,13,9

Answers

12.545 is the answer

Answer:

12.54

Step-by-step explanation:

When finding the mean, first you add all the numbers in the data:

9+14+14+9+20+6+8+19+17+13+9=138

And then you divide it by the following numbers in the set. In this data set, since there are 11 numbers, you would divide 138 by 11.

138\11=12.5454545

So the answer would be 12.54 if your rounding to the nearest hundred. If your rounding it by a whole number, it would be 13.
