Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below
Xelga [282]

Answer:

The job should be offered to Kaitlyn

Step-by-step explanation:

From the question we are told that

   The data for  Demetria is

      Test score is  71.4

      The mean is  66.6

      The standard deviation is 8

Generally the z-sore for Demetria is mathematically evaluated as

        z - score  =  \frac{ 71.4 - 66.6 }{ 8}

= >     z - score  = 0.6

   The data for  Norma is

      Test score is  258.3

      The mean is  238

      The standard deviation is  29

Generally the z-sore for Norma  is mathematically evaluated as

        z - score  =  \frac{ 258.3 - 238 }{ 29}

= >     z - score  = 0.7

   The data for  Kaitlyn is

      Test score is  8

      The mean is 7.2

      The standard deviation is  0.4

Generally the z-sore for Norma  is mathematically evaluated as

        z - score  =  \frac{ 8 - 7.2}{ 0.4}

= >     z - score  = 2

Now given that the z-score of  Kaitlyn is the highest it means that performed best and should be given the job

It is now 3:15 pm. Is it possible to drive 135 miles and arrive before 5:00 pm if ypu drove 55 mph? Explain your answer
Troyanec [42]
Well, how long will it take you to drive 135 miles at 55mph?

at 55 mph, you're doing 55 miles every hour, so we can simply get the quotient of 135/55 and that's how many hours it'll take you to drive 135 miles at that speed.

\bf \cfrac{135}{55}\implies \cfrac{27}{11}\implies 2\frac{5}{11}~hours\implies \textit{about 2hrs, 27 minutes}

so, it takes you that long, however, from 3:15 to 5:00pm there are only 45mins + 60mins or 1hr and 45 minutes, namely 1¾ hr.

so 2hrs and 27 minutes is much later than 1¾ hr, so, no dice, you can't arrive at 5pm, actually you'll arrive around 5:42pm.
