Data is collected only once from a participant is not a characteristic of a longitudinal study. Thus, the correct option is A.

<h3>What is a Longitudinal study?</h3>

A Longitudinal study may be defined as a scientific approach to a specific research that involves recounted compliances of the duplicate variables over short or long periods of time.

A longitudinal study involves the collection of data from the same participants at different points in time, collection of data from a large sample size at the same time, and collection of data that can span over several years.

Therefore, the correct option for this question is A.

Hugo plans to buy packs of baseball cards until he gets the card of his favorite player, but he only has enough money to buy at
netineya [11]

Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

<h3>What is the discrete probability distribution?</h3>

Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:

  • P(X = 1) = 0.2.
  • P(X = 2) = 0.16.
  • P(X = 3) = 0.128.
  • P(X = 4) = 0.512.

The probability that he buys fewer than 3 packs is given by:

P(X < 3) = P(X = 1) + P(X = 2).

Hence:

P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.

There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

Arrange the following in order of decreasing basicity. mgo, cs2o, cl2o7, sno2, p4o10
rosijanka [135]

Basicity of oxides decreases for elements from left to right in the periodic table. The order of increasing basicity is; Cs2O> MgO > SnO2 > P4O10 > Cl2O7.

The oxides of metals are known to be basic. This is a common property of all metals. However, the basicity of metallic oxides decreases across the period. So, from left to right, the oxides of bases become less acidic.

On the other hand, the oxides of nonmetals are acidic in nature. So as we move from left to right, the oxides of metals become more acidic. The order of decreasing  basicity of oxides as listed in the question is;

Cs2O> MgO > SnO2 > P4O10 > Cl2O7.

Use the story "the landlord's mistake" from fifty famous people by james baldwin to answer the question.
shepuryov [24]

The theme of the story ""The Landlord's Mistake" from Fifty Famous People by James Baldwin to answer the question" is "treat everyone with equality and kindness"

The complete question:

In one to two sentences, describe the theme of the excerpt.

<h3>The story "The Landlord's Mistake" from Fifty Famous People by James Baldwin</h3><h3 />

When John Adams was president and Thomas Jefferson was vise president of the United States, there was not a railroad in all the world.

People did not travel very much. There were no broad, smooth highways as there are now. The roads were crooked, muddy, and rough.

If a man had to go from one city to another, he often rode on horseback. Instead of a trunk for his clothing, he carried a pair of saddlebags. Instead of sitting at his ease in a parlor car, he went jolting along thru mud and mire, exposed to wind and weather.

One day, some men were sitting by the door of a hotel in Baltimore. As they looked down the street, they saw a horseman coming. He was riding very slowly, and both he and his horse were bespattered with mud.

"There comes old Farmer Mossback," said one of the men, laughing. "He's just from the backwoods."

Another said, "He seems to have had a hard time of it." I wonder where he'll put up for the night.

"Oh, any kind of place will suit him," answered the landlord. "He's one of those country fellows who can sleep in the haymow and eat with the horses."

The traveler was soon at the door. He was dressed plainly, and, with his reddish-brown hair and mud-bespattered face, looked like a hard-working countryman just out of the backwoods.

"Have you got a room here for me?" he asked the landlord.

Now the landlord prided himself on keeping a first-class hotel, and he feared that his guests would not like the rough-looking traveler. So he answered: "No, sir. Every room is full. The only place I could put you would be in the barn. "

Well, then, "answered the stranger," I will see what they can do for me at the Planters' Tavern, round the corner;" and he rode away.

About an hour later, a well-dressed gentleman came into the hotel and said, "I wish to see Mr. Jefferson."

"Mr. Jefferson!" said the landlord.

"Yes, sir. "Thomas Jefferson, the vise president of the United States."

"He isn't here."

Oh, but he must be. I met him as he rode into town, and he said that he intended to stop at this hotel. He has been here for about an hour. "

"No, he hasn't. The only man that had been here for lodging today was an old clodhopper who was so spattered with mud that you couldn't see the color of his coat. I sent him round to the Planters'. "

Did he have reddish-brown hair, and did he ride a gray horse?

"Yes, and he was quite tall."

"That was Mr. Jefferson," said the gentleman.

"Mr. Jefferson!" cried the landlord. Was that the vise president? Here! Build a fire in the best room. Put everything in tiptop order, Sally. What a dunce I was to turn Mr. Jefferson away! He shall have all the rooms in the house, and the ladies' parlor, too. I'll go right round to the Planters' and fetch him back. "

So he went to the other hotel, where he found the vise president sitting with some friends in the parlor.

"Mr. Jefferson," he said, "I have come to ask your pardon. You were so bespattered with mud that I thought you were some old farmer. If you come back to my house, you'll have the best room in it—yes, all the rooms if you wish. Won't you come? "

"No, "answered Mr. Jefferson. "A farmer is as good as any other man; and where there's no room for a farmer, there can be no room for me."

The story teaches to be fair with everyone irrespective of their looks, dress or physical characteristics. He treated the vice president Mr Jefferson badly because he thought Mr Jefferson was a poor farmer.
