What is the standard error of the mean?

The standard error of the mean, or simply standard error, indicates how different the population means is likely to be from a sample mean. It tells you how much the sample means would vary if you were to repeat a study using new samples from within a single population.

Therefore, The value of the standard error of the mean is 1.256.

Hannah paid $8.63 at the grocery store for beans and potatoes. She bought 4 pounds of beans at $0.62 per pound and 5 pounds of potatoes.

How much did Hannah pay per pound for the potatoes?
$3.67

$1.32

$6.15

$1.23

Answers

Answer:

$1.23

Step-by-step explanation:

First start off by multiplying $0.62 by 4 to find out the total she paid for all four pounds of beans. This would give you $2.48 spent on beans. Subtract $2.48 from the total amount spent ($8.63). You now have $6.15 left on what she could have spent on 5 pounds of potatoes. Do $6.15 divided by 5 to get an answer of $1.23. Hannah paid $1.23 per pound for the potatoes.

the median is 5 the mode is 5 and 2 the mean is 6.25 and the range is 15

the mode is 5 and 2 because they both occur the most often

The median is 5 because even though the amount of numbers is even and there is no exact middle the two middle numbers are both 5 and 5+5 equals 10 divided by 2 equals 5

the mean is 6.25 because all numbers added together 75 divided by the amount of numbers 12 equals 6.25

if a half a gallon of milk costs $1.24 then whats the cost per pint?

Answers

Answer:

Step-by-step explanation:

It costs . 31 cents for 1 pint of milk.

Answer:

1 pint would be ($1.25/4 pints) = $0.31

Step-by-step explanation:

There are eight pints in a US gallon, and thus four in half a gallon.

That comes to four pints of milk.

That's $1.24/(half gallon), or $2.48/gallon.

Since half a gallon (4 pints) is $1.25, 1 pint would be ($1.25/4 pints) = $0.31

Ms. Carey grades 4 tests during her lunch. She grades 1/3 of the remainder after school. If she syill5has 16 test to grade after school, how many test are there?
​

Answers

Answer: 24 tests

Step-by-step explanation:

Ms. Carey graded 1/3 of the tests and still had 16 tests to go.

This means that the 16 tests represent the remaining proportion of the total number of tests:

= 1 - 1/3

= 2/3

2/3 of the total is equal to 16 tests. Assuming the total is x, the expression would be:

2/3x = 16

x = 16 ÷ 2/3

x = 16 * 3/2

x = 24 tests

Name 5 of the 7 factors that determine development according to the UN [Chairman Gonzalo]: I think this question deserves a detailed explanation. Concerning the party, Chairman Mao teaches usas did Marx, Lenin, and all the great Marxiststhat the party is not a mass party, though it has a mass character. It has a mass character in the sense that while being a select organizationa selection of the best, of the proven, of those, as Stalin said, who have what it takesbeing numerically small in proportion to the broad masses, the party defends the interests of the proletariat in taking responsibility for its emancipation, which can only come with communism. But since other classes that make up the people also participate in the revolution, the party defends their interests as well.[El Diario]: Chairman, lets talk about the peoples war now. What does violence mean to you?[Chairman Gonzalo]: We see the problem of war this way: war has two aspects, destructive and constructive. Not to see it this way undermines the revolutionweakens it. From the moment the people take up arms to overthrow the old order, the reaction [state] seeks to crush, destroy, and annihilate the struggle, and it uses all the means at its disposal, including genocide.

The Long Walk to FreedomThink #1 Use details from the first paragraph to explain the social and political changes that have taken place in South Africa since the 1990s.South Africa has had a long and challenging history. Things started to change both politically and socially in the 1990's. This is because ________________________ (author, year, paragraph #). There are several examples of these changes. One example of social change has been _________________________________ (author, year, paragraph #). Another example of social change has been seen in ________________________________ (author, year, paragraph #). Social change has not been the only area to see a difference as the politics in South Afica also changed. One example of this is _______________________________(author, year, paragraph #). A second political change has been ______________________________(author, year, paragraph #). Today there are still issues in South Africa, but they have made great strides forward since the 1990's.Think #2 Write two or three sentences explaining Mandelas point of view about courage and his reaction to fear. Support your answer with evidence from paragraph 4.Nelson Mandela had a lot of time to collect his thoughts while he was wrongly imprisoned in South Africa. In the excerpt from A Long Walk Home, Mandela shares his views on courage and fear. He writes that courage is ______________________________ (author, year, paragraph). He best explains it as __________________________ (author, year, paragraph). Mandela also writes about fear. He say, " _____ (author, year, paragraph)".Think #3 Refer to multiple details to explain Mandelas view of a persons twin obligations - both from ideas that are directly stated in paragraph 7 and from ideas you have inferred from clues in the text.In the excerpt by Nelson Mandela he wrote about having "twin obligations". The reader can infer this to mean ______________________ based on the evidence from context clues that discusses _____________________________ (author, year, paragraph #). Mandela states the following about twin obligations, "___________________________________" (author, year, paragraph #).Think #4 Use context clues and word relationships to determine the meaning of the word resiliency as it is used in paragraph 4 of Long Walk to Freedom. Write your definition of resiliency and tell how you determined its meaning.Based on the text and context clues, the definition of resiliency means ______________________________ (author, year, paragraph #). The context clues in the text that support this definition are, "____________________________ (author, year, paragraph #)".Think #5 By recalling that the Latin prefix trans- means across or to change completely and that the suffixation means act or process, use the context clues provided in paragraph 5 to determine the meaning of transformation. Write your definition of transformation here and tell how you figured out its meaning.From the root meaning of "trans" (across or to change completely) and the suffix "ation" meaning act of process the word transformation in paragraph 5 is defined as _______________________. The context clues in the text support the definition where it states, "________________________ (author, year, paragraph)".
