Answer:

h(0)=10

h(4)=16

Step-by-step explanation:

for h(0) you would need to do the second equation because it is within the bounds of the variable.

h(0)= 2x^2 - 3x + 10

anything times 0 is 0

so 2(0)^2 - 3(0) + 10=

0-0+10=

Solve each system of equations by substitution
x + 4y = 19
x - 2y = 1

What is the product of x and y ?

Answers

x + 4y = 19
x = 19 - 4y

*substitute it for the second equation*
x - 2y = 1
19 - 4y - 2y = 1
19 - 6y = 1
-6y = -18
y = 3

x + 4y = 19
x + 12 = 19
x = 7

x.y = 3.7 = 21

The value of product of x and y is, 21

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

WE have to given that;

System of equation ae,

x + 4y = 19  .. (i)

x - 2y = 1 .. (ii)

From (i);

x + 4y = 19

x = 19 - 4y

substitute it for the (ii) equation;

x - 2y = 1

19 - 4y - 2y = 1

19 - 6y = 1

-6y = -18

y = 3

Hence, From (i);

x + 4y = 19

x + 12 = 19

x = 7

So, The value of product of x and y is,

x × y = 3 × 7 = 21

Jamal is making a snack mix that contains only pretzels and nuts. For every ounce of nuts, he will use 2 ounces of pretzels.
How many ounces of pretzels and how many ounces of nuts does he need to make 45 ounces of snack mix?

Answers

Answer:

Pretzels: 30 ounces, Nuts: 15 ounces

Step-by-step explanation:

Trust me.

Number of ounces of nuts = 30

Number of ounces of pretzels = 15

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Jamal is making a snack mix with pretzels and nuts.

And, For every ounce of nuts, he will use 2 ounces of pretzels.

Total number of snake mix = 45 ounces

Now,

Let number of ounces of pretzels = y

Let number of ounces of nuts = x

So, We can formulate;

⇒ x = 2y    ... (i)

And, x + y = 45     .... (ii)

Substitute the value of x in equation (ii) , we get;

x + y = 45  

2y + y = 45  

3y = 45

y = 15

And,

x + y = 45  

x + 15 = 45

x = 30

Therefore,

Number of ounces of nuts = 30

Number of ounces of pretzels = 15

It was found that 61 percent of the tourists to China visited the Forbidden City, the Temple of Heaven, the Great Wall, and other historical sites in or near Beijing. 33 percent visited Xi'an with its magnificent terracotta soldiers, horses, and chariots, which lay buried for over 2000 years. 18 percent of the tourists went to both Beijing and Xi'an. What is the probability that a tourist visited at least one of these places

Answers

Answer:

0.76 = 76% probability that a tourist visited at least one of these places

Step-by-step explanation:

I am going to solve this question using the probabilities as Venn sets.

We have that:

Event A: Tourist visited Beinjing.

Event B: Tourist visited Xi'an.

61 percent of the tourists to China visited the Forbidden City, the Temple of Heaven, the Great Wall, and other historical sites in or near Beijing.

This means that [tex]P(A) = 0.61[/tex]

33 percent visited Xi'an with its magnificent terracotta soldiers, horses, and chariots, which lay buried for over 2000 years.

This means that [tex]P(B) = 0.33[/tex]

18 percent of the tourists went to both Beijing and Xi'an.

This means that [tex]P(A \cap B) = 0.18[/tex]

What is the probability that a tourist visited at least one of these places?

This is

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

We already found these values. So

[tex]P(A \cup B) = 0.61 + 0.33 - 0.18 = 0.76[/tex]

0.76 = 76% probability that a tourist visited at least one of these places

Answer:

The procedure does results in a binomial distribution.

Step-by-step explanation:

For a binomial probability distribution to be applicable, certain conditions have to be met which are :

There must be a fixed number of observations ; here the number of observations are : 79

All observations must be independent ; the observations are independent ; odd or even

Observations must fall into one of two categories : success category or failure. Here, observations can be odd or even

The probability of success must be equally likely for each observation.

Hence, the procedure results in a binomial probability distribution.

Answers

Answer:

−35.713332 ; 0.313332

Step-by-step explanation:

Given that:

Sample size, n1 = 11

Sample mean, x1 = 79

Standard deviation, s1 = 18.25

Sample size, n2 = 18

Sample mean, x2 = 96.70

Standard deviation, s2 = 20.25

df = n1 + n2 - 2 ; 11 + 18 - 2 = 27

Tcritical = T0.01, 27 = 2.473

S = sqrt[(s1²/n1) + (s2²/n2)]

S = sqrt[(18.25^2 / 11) + (20.25^2 / 18)]

S = 7.284

(μ1 - μ2) = (x1 - x2) ± Tcritical * S

(μ1 - μ2) = (79 - 96.70) ± 2.473*7.284

The Civil War had been raging for years, and hundreds of thousands of Americans were dead. The war was nearly over, but President Lincoln would not see the country reunited. He was assassinated in April 1865.Fellow-Countrymen:At this second appearing to take the oath of the Presidential office there is less occasion for an extended address than there was at the first. Then a statement somewhat in detail of a course to be pursued seemed fitting and proper. Now, at the expiration of four years, during which public declarations have been constantly called forth on every point and phase of the great contest which still absorbs the attention and engrosses the energies of the nation, little that is new could be presented. The progress of our arms, upon which all else chiefly depends, is as well known to the public as to myself, and it is, I trust, reasonably satisfactory and encouraging to all. With high hope for the future, no prediction in regard to it is ventured.On the occasion corresponding to this four years ago all thoughts were anxiously directed to an impending civil war. All dreaded it, all sought to avert it. While the inaugural address was being delivered from this place, devoted altogether to saving the Union without war, insurgent agents were in the city seeking to destroy it without warseeking to dissolve the Union and divide effects by negotiation. Both parties deprecated war, but one of them would make war rather than let the nation survive, and the other would accept war rather than let it perish, and the war came.One-eighth of the whole population were colored slaves, not distributed generally over the Union, but localized in the southern part of it. These slaves constituted a peculiar and powerful interest. All knew that this interest was somehow the cause of the war. To strengthen, perpetuate, and extend this interest was the object for which the insurgents would rend the Union even by war, while the Government claimed no right to do more than to restrict the territorial enlargement of it. Neither party expected for the war the magnitude or the duration which it has already attained. Neither anticipated that the cause of the conflict might cease with or even before the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible and pray to the same God, and each invokes His aid against the other. It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces, but let us judge not, that we be not judged. The prayers of both could not be answered. That of neither has been answered fully. The Almighty has His own purposes. "Woe unto the world because of offenses; for it must needs be that offenses come, but woe to that man by whom the offense cometh." If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South this terrible war as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a living God always ascribe to Him? Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondsman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether."With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.How does Lincoln's use of the phrases "malice toward none," "charity for all," and "firmness in the right" affect Paragraph 4?A. They highlight the innovative nature of Lincoln's ideas.B. They demonstrate Lincoln's belief in retribution.C. They suggest that success and victory are guaranteed.D. They help convey the loftiness and virtue of his message.How do the impact identified in Part A and Lincoln's use of repetition at the beginning of Paragraph 4 advance his purpose?A. They encourage people to agree that the opposition brought the war on itself. B. They develop support for the idea of ending the war at all costs. C. They rally greater belief in the cause for which one side is fighting the war. D. They work to inspire unification in support of a moral resolution of the war.

He had the finest aviary in Europe, so large that eagles did not find it uncomfortable, so well laid out that both humming birds and snowbuntings had a climate that suited them perfectly. But for many years the finest set of apartments remained empty, with just a label saying: "PHOENIX. Habitat: Arabia." Many authorities on bird life had assured Lord Strawberry that the phoenix is a fabulous bird, or that the breed was long extinct. Lord Strawberry was unconvinced: his family had always believed in phoenixes. At intervals he received from his agents (together with statements of their expenses) birds which they declared were the phoenix but which turned out to be orioles, macaws, turkey buzzards dyed orange, etc., or stuffed cross-breeds, ingeniously assembled from various plumages. Finally Lord Strawberry went himself to Arabia, where, after some months, he found a phoenix, won its confidence, caught it, and brought it home in perfect condition.It was a remarkably fine phoenix, with a charming character affable to the other birds in the aviary and much attached to Lord Strawberry. On its arrival in England it made a greatest stir among ornithologists, journalists, poets, and milliners, and was constantly visited. But it was not puffed by these attentions, and when it was no longer in the news, and the visits fell off, it showed no pique or rancour. It ate well, and seemed perfectly contented. It costs a great deal of money to keep up an aviary. When Lord Strawberry died he died penniless. The aviary came on the market. In normal times the Rarer birds, and certainly the phoenix, would have been bid for by the trustees of Europes great zoological societies, or by private persons in the U.S.A.; but as it happened Lord Strawberry died just after a world war, when both money and bird-seed were hard to come by (indeed the cost of bird-seed was one of the things which had ruined Lord Strawberry). The London Times urged in a leader that the phoenix be bought for the London Zoo, saying that a nation of bird-lovers had a moral right to own such a rarity; and a fund, called the Strawberry Phoenix Fund, was opened. Students, naturalists, and school-children contributed according to their means; but their means were small, and there were no large donations. So Lord Strawberrys executors (who had the death duties to consider) closed with the higher offer of Mr. Tancred Poldero, owner and proprietor of Polderos Wizard Wonderworld. For quite a while Mr. Poldero considered his phoenix a bargain. It was a civil and obliging bird, and adapted itself readily to its new surroundings. It did not cost much to feed, it did not mind children; and though it had no tricks, Mr. Poldero supposed it would soon pick up some. The publicity of the Strawberry Phoenix Fund was now most helpful. Almost every contributor now saved up another half-crown in order to see the phoenix. Others, who had not contributed to the fund, even paid double to look at it on the five-shilling days. But then business slackened. The phoenix was as handsome as ever, and amiable; but, as Mr. Poldero said, it hadnt got Udge. Even at popular prices the phoenix was not really popular. It was too quiet, too classical. So people went instead to watch the antics of the baboons, or to admire the crocodile who had eaten the woman. One day Mr. Poldero said to his manager, Mr. Ramkin: "How long since any fool paid to look at the phoenix?" "Matter of three weeks," replied Mr. Ramkin. "Eating his head off," said Mr. Poldero. "Let alone the insurance. Seven shillings a week it costs me to insure the Archbishop of Canterbury." "The public dont like him. Hes too quiet for them, thats the trouble. Wont mate nor nothing. And Ive tried him with no end of pretty pollies, ospreys, and Cochin-Chinas, and the Lord knows what. But he wont look at them." "Wonder if we could swap him for a livelier one," said Mr. Poldero. "Impossible. Theres only one of him at a time." "Go on!" "I mean it. Havent you ever read what it says on the label?" They went to the phoenixs cage. It flapped its wings politely, but they paid no attention. -Kim What British demand led to the Opium Wars in China?

Just curious, I want to see who can get this. tooooootttalllllly know it alreadyAssume that we have two variables a and b, and that: a = bMultiply both sides by a to get: a2 = abSubtract b2 from both sides to get: a2 - b2 = ab - b2This is the tricky part: Factor the left side (using FOIL from algebra) to get (a + b)(a - b) and factor out b from the right side to get b(a - b). If you're not sure how FOIL or factoring works, don't worryyou can check that this all works by multiplying everything out to see that it matches. The end result is that our equation has become: (a + b)(a - b) = b(a - b)Since (a - b) appears on both sides, we can cancel it to get: a + b = bSince a = b (that's the assumption we started with), we can substitute b in for a to get: b + b = bCombining the two terms on the left gives us: 2b = bSince b appears on both sides, we can divide through by b to get: 2 = 1
