The answer would be the third option because the first two have improper word placement. Read the first two sentences out loud and you will notice how weird they sound. The third option sounds very clear which is why it is the correct option.

The average size of a certain computer datafile is 255 kilobytes. 10 million of these datafiles can be stored in a harddisk.
mr_godi [17]

Answer:

Hi! Your answer here is 2550 GB. To find this answer, we multiply 255 (the number of kb) by 10,000,000 (the number of files.) This gives us 2,550,000,000 KB. There are 1,000,000 kb in 1 GB, so we divide 2,550,000,000 by 1,000,000, which gives us 2550. 2550 GB of files can be stored.

agasfer [191]

Answer:

The probability of randomly selecting someone who does not believe that statistics teachers know the true meaning of life is 0.426.

Step-by-step explanation:

Let <em>X</em> = number of Americans who believe that statistics teachers know the true meaning of life.

The probability of the random variable <em>X</em> is,

P (X) = 0.574

The event of a person not believing that statistics teachers know the true meaning of life is the complement of the event <em>X</em>.

The probability of the complement of an event, <em>E</em> is the probability of that event not happening.

P(E^{c})=1-P(E)

Compute the value of P(X^{c}) as follows:

P(X^{c})=1-P(X)\\=1-0.574\\=0.426

Thus, the probability of randomly selecting someone who does not believe that statistics teachers know the true meaning of life is 0.426.
