Answer:

The Rome data center is best described by the mean. The New York data center is best described by the median

Step-by-step explanation:

Before moving forward, first we should understand that what is mean and median. Mean is the average of all the values in the data set. Median is the middle value of the data set in ascending order. As we noticed that there is an outlier in the data for NEW YORK (An outlier is an extreme value in the data set which is much higher or lower as compared to other numbers. It affects the mean value). Since outlier is found in the data of New York therefore mean is not a good representation on the central tendency of the data and gets distorted by the outlier. Therefore it is better to use median. While Rome does not have any outlier, so we can use mean for this.

Therefore we can say that the Rome data center is best described by the mean. The New York data center is best described by the median.

Thus option C is correct....

This is a linear relationship because:

(20-10)/(4-2)=(35-20)/(7-4)=m=5

So we have a line with a slope of 5, and the slope intercept form of a line is:

y=mx+b, and we have found that m=5

y=5x+b, now using any point we can solve for b, use (2,10)

10=5(2)+b

10=10+b

0=b so the line is:

y=5x

You can win concert tickets from a radio station if you are the first person to call when the song of the day is played, or if y
Anit [1.1K]

The song of the day is announced at a random time between 7:00 and 7:30, so you have a 30-minutes span of time where the song could be announced. If you start listening to the radio 20 minutes in, you're at 2/3 of the time. So, there is a 2/3 chance that the song has already been chosen, and a 1/3 chance that it will be announced in the remaining 10 minutes.

Similarly, the trivia question is asked at a random time between 7:15 and 7:45 so there is again a 30-minutes span of time. But this time, we're only 5 minutes late, so there is a 5/30=1/6 chance that the question was already asked, and a 25/30=5/6 chance that the question will be asked in the remaining 25 minutes.

So, there are four scenarios:

  • You have missed both the song of the day and the trivia question. Given all we said, this event has a chance of

\dfrac{2}{3}\cdot\dfrac{1}{6} =\dfrac{2}{18}

  • You miss the song, but not the trivia:

\dfrac{2}{3}\cdot\dfrac{5}{6} =\dfrac{10}{18}

  • You miss the trivia, but not the song

\dfrac{1}{3}\cdot\dfrac{1}{6} =\dfrac{1}{18}

  • You don't miss anything:

\dfrac{1}{3}\cdot\dfrac{5}{6} =\dfrac{5}{18}

You're interested in the probability of missing either of the announcements, so you want to sum the two middle cases (in the first you miss everything, in the second you don't miss anything).

Your result is thus

\dfrac{10}{18}+\dfrac{1}{18} = \dfrac{11}{18}

Answer:

a. $3,260.

Step-by-step explanation:

Tyler is planning to buy a new car. He intends to trade in his existing car, a 2002 Chrysler Sebring in good condition. Using the table below, we need to estimate about how much Tyler’s car is worth.

Given table is

Model/Year 2000    2001   2002   2003   2004

Pacifica   $2,194  $2,288 $2,605 $2,690 $2,814

Concorde   $1,842  $1,998 $2,180 $2,781 $2,925

Sebring    $2,920  $3,075 $3,260 $3,551 $3,912

300M       $2,770  $2,934 $3,095 $3,188 $3,676


Given choices are:

a. $3,260

b. $2,920

c. $2,605

d. $3,188


"2002 Chrysler Sebring" means look for the column of table which has year 2002. Then look for the row of the table which says "Sebring". Now we see that both rows and columns intersect at value $3,260.

Hence final answer is a. $3,260.
