FGE is a straight line, and striaght lines measure 180 by definition. Therefore, x, angle BGA, and 55 all add together to equal 180. But notice that x and 55 are both marked with a single swish, meaning they are the same measure. So:

180 - 55 - 55 = x, so

x = 70

A sociologist recently conducted a survey of citizens over 60 years of age who have net worths too high to qualify for Medicaid but have no private health insurance. The ages of the 25 uninsured senior citizens were as follows: Suppose the mean and standard deviation are 74.04 and 9.75, respectively. If we assume that the distribution of ages is mound-shaped and symmetric, what percentage of the respondents will be between 64.29 and 93.54 years old

Answers

Answer:

81.85% of the respondents will be between 64.29 and 93.54 years old

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Mean and standard deviation are 74.04 and 9.75

This means that [tex]\mu = 74.04, \sigma = 9.75[/tex]

What percentage of the respondents will be between 64.29 and 93.54 years old?

The proportion is the pvalue of Z when X = 93.54 subtracted by the pvalue of Z when X = 64.29. So

X = 93.54

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{93.54 - 74.04}{9.75}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a pvalue of 0.9772.

X = 64.29

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{64.29 - 74.04}{9.75}[/tex]

[tex]Z = -1[/tex]

[tex]Z = -1[/tex] has a pvalue of 0.1587.

0.9772 - 0.1587 = 0.8185

0.8185*100 = 81.85%

81.85% of the respondents will be between 64.29 and 93.54 years old

choose yes or no to tell whether each of the following describes a convenience sampling method​

Answers

No, this is systematic sampling. Systematic sampling is where you use a specifically well defined rule to generate your sample. In this case, that rule is "pick every 4th customer". In other words, if the customer number is a multiple of 4, then they are selected.No, this is simple random sampling (SRS). Each school is assigned a number, and those numbers are fed into a computer to generate a list of schools to form the sample. A random number table can also be used. When comparing to systematic sampling, SRS in my opinion is the stronger sampling method in that we get a better representative sample. Consider a case where on some unlucky circumstance that every 4th customer happens to be male (refer to problem 1). That would mean males are over-represented while females are completely under-represented. This example, while a bit extreme, shows a flaw in systematic sampling. So in short, it's best to use SRS if you could only pick one.  Yes, this is convenience sampling. As the name strongly implies, convenience sampling is the easiest or most convenient way to select a sample. Sheila simply looked to her left and right to get the sample points she needed. While it's tempting to use this method due to its ease, it's probably very clear that this method can be heavily biased. She should employ SRS to get a better representative sample.Yes, this is convenience sampling. For the quality control manager, the easiest most convenient ladders he found were the first five closest to him. Those five ladders may or may not be representative of the population. The population being the set of all ladders in the shop. If those ladders don't break, then the manager may get the wrong conclusion that all if not most of the ladders won't break. However, his sample is not representative and there may be bad faulty ladders in the shop somewhere. He should do a SRS to address this problem. Perhaps even a cluster sample where he breaks the shop's floor area into various chunks and does random sampling based on that. A cluster sample is useful because some areas of the shop may be better or worse off compared to others. Eg: if there's a leak in the roof in one spot, or if there's more moisture, then that cluster is different from the rest that don't have such issues.

In short, we have these answers in this exact order: No, No, Yes, Yes.

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

60% = 60/100 = 60 ÷ 100 = 0.6.

100% = 100/100 = 100 ÷ 100 = 1.

A furniture salesman makes 3.5% commission. Her monthly sales are $18,545. Her annual salary is $18,995.80. What’s her monthly pay? Write just the value that represents your answer.

Answers

Using proportions, it is found that her monthly salary is of $1,528.9.

What is a proportion?

A proportion is a fraction of total amount.

In this problem, her monthly sales are $18,545, with a commission of 3.5%, hence, in commission, the amount she makes is:

0.035 x 18545 = 649.075

Her annual salary is $18,995.80, of which 18995.80 - 649 = $18,346.8 she receives in 12 payments, hence:

18,346.8/12 = $1,528.9.

Her monthly salary is of $1,528.9.

  short leg : long leg = SP/RS = RS/SQ   ⇒   RS² = SP·SQ

  short leg : hypotenuse = RP/PQ = PS/RP   ⇒   RP² = PS·PQ

  long leg : hypotenuse = RQ/QP = QS/RQ   ⇒   RQ² = QS·QP

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?
