Answer:

B). Number of distractions; performance scores on the exam

Explanation:

In a psychological experiment, the dependent variable exemplifies the variable which is being tested or examined in an experiment while the independent variable is the one that is manipulated and changes.

AveGali [126]

Hello. This question is incomplete. The full question is:

Mio Strand is in the Province of Suruga. Its sand is yellow and fine, strewn with rose shells at the ebb tide. Its pine trees are ancient and they lean all one way, which is the way that the wild wind wills. Before Mio rolls the deep sea, and behind Mio rises Fugi, the most sacred, the mountain of mountains. Small marvel that the Strange People should come to Mio. Of the Strange People not much is known, even at Mio, though it is sure they come there. It seems they are shy indeed, more’s the pity. They come through the blue air, or across the mysterious paths of the sea. Their footprints are never, never seen upon the wet beach, for they tread too lightly. But sometimes in their dancing they sweep their robes upon the sand and leave it ribbed and ruffled; so, often enough, it may be seen at Mio. What effect is accomplished by the author beginning the story with these descriptions?

Answer:

The author wishes to create a mystical and mysterious atmosphere for the text.

Explanation:

The author uses a descriptive language, with a wide use of adjectives that aims to show how Mio Strand and its inhabitants, as well as its atmosphere has a tone of mystery, mysticism and something beyond our reality. With this, the author creates a tone for the story, which ritualizes the reader about how the mood of the narrative will be. In other words, we can say that the author's intention is to create a mysterious and mystical mood.

90% of runners in a marathon successfully completed it. 30% of these runners were men. How many total runners began the marathon
Semmy [17]

The total runners who began the marathon is 1000

<u>Explanation:</u>

Given:

Runners who completed the marathon = 90%

Men = 30%

Number of men completed the marathon = 270

Total runners who began the marathon = ?

Let the total runners be x

According to question:

Runners who completed the marathon = \frac{90}{100} X x

                                                                 = 0.9x

and,

\frac{30}{100} X 0.9 x = 270

Solving further:

0.9x = \frac{270 X 100}{30} \\\\x = \frac{270 X 100}{30 X 0.9} \\\\x = 1000

Therefore, total runners who began the marathon is 1000
