plz no spam if your answer is write I will like and mark as brainliest answer ​

Answer 1

Answer:

-98.36

Explanation:

Given the data :

Marks 0-10 10-20 20-30 30-40 40-50 50-60

no.of students : 15. 20. 35. p. 10. 42

The given mean = 24

This is a grouped data:

The formula for the mean is :

Σfx / Σf

Where, x = midpoint ; f = frequency

The midpoint, x = (upper - lower limit) / 2

Midpoint of marks, x :

Marks _____ x ____ Frequency

0 - 10 _____ 5 ______ 15

10 - 20 ____ 15 _____ 20

20 - 30 ____25 _____35

30 - 40 ____35 _____ p

40 - 50 ____45 _____ 10

50 - 60____ 55 _____ 42

[(5*15) + (15*20) + (25*35) + (35*p) + (45*10) + (55*42)] / (15+20+35+p+10+42) = 24

(75+300+875+35p+450+2310) / (122 + p) = 24

(4010 + 35p) / (122 + p) = 24

4010 + 35p = 24(122+p)

4010 + 35p = 2928 + 24p

4010 - 2928 = 24p - 35p

1082 = - 11p

p = 1082 / - 11

p = - 98.36

Kindly check the distribution given again as obtaining a negative value isn't ideal.

Lines in the poem as a whole and/or the number of lines in each stanza. When the organizational structure of your writing has already been determined, either by you or the rhetorical situation, this style is referred to as fixed form.

A sonnet is a fixed poetry form with 14 lines that often rhyme in a predetermined way and are written in five-foot iambic pentameter. It is believed to have come from Italy. The sonnet stands out above other literary forms in Western literature because it has captured the attention of notable writers for five centuries.

A series of services celebrated in religious communities are called the

A. daily Offices.

B. Mass.

C. Proper.

D. Ordinary.

Answers

Answer:

b tell me if im wrong

Explanation:

The correct option is B. A series of services celebrated in religious communities are called the Mass. A ritualistic recreation of Christ's Last Supper with his followers is the Mass. The main rite of the Roman Catholic Church that is attended by members of the general public is the Mass, which is typically the most solemn. The Proper and Ordinary prayers, which make up the Mass, were separated into two groups.

Why is the Mass a sacrifice?

So Christ is not re-hung on a cross during the Mass. It continues to commemorate His one atonement, which is eternal. If God is genuinely eternal and infinite, then His humanity died on Good Friday in the Person of Jesus Christ, and this act must have transcended the boundaries of time.

The Holy Week ceremony known as the Mass of the Lord's Supper is held on Maundy Thursday evening and is also referred to as A Service of Worship for Maundy Thursday. In contrast to previous Mass celebrations, it marks the beginning of the Easter Triduum and more explicitly remembers Jesus' Last Supper with his apostles.

What is the author’s position in this essay?

The author’s position in this essay is that adopting a pet from a shelter is the most responsible way to add a pet to your family.

Explanation:

What is the reason why?

Because the city’s animal shelters are already overflowing with pets in need of a loving family, some of which were lost, abandoned, or have never even had a home before. They have kittens and puppies, for those that prefer raising a pet since they are little, as well as adult animals that have already been housebroken for those who rather avoid the hassle of disciplining a new pet. There are pets for all kinds of needs, including active families, or pets suitable for apartment living.

É em meados da Idade Média (que durou do século V ao XV) quando o homem rompe com o passado e desperta de forma intensa para outra possibilidade de adoção da indumentária; nascendo assim, o encanto pelo vestuário como peça alegórica e, somente a partir do fim da Idade Média que se reconhece a moda como sistema através da renovação das formas e de sua extravagância. Toda a conjuntura política ao longo dos anos na Idade Média leva à troca de informações e conhecimento sobre outras culturas contemporâneas que foram alimentando tal despertar.

Jayden read an article about Pablo Picasso for a research report. He needs to locate the name of a painting in the article. Would Jayden use skimming or scanning to find the name of the painting? Why is this reading rate appropriate?

Answers

Answer: scanning

Explanation:

Jayden should use scanning to find the name of the painting.

While skimming aims to get a general idea of a text by reading rapidly, scanning refers to reading rapidly to find specific information. Although both reading techniques involve rapid reading, they are quite different. The first one requires retaining as much information as possible while rapidly reading to make connections that allow a general idea of the text.  Whereas scanning only requires looking for a specific piece of data, so there´s no need to retain other information, but requires much more attention to detail.
