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

.
Nico got a score of 103.2; this version has a mean of 69.6 and a standard deviation of 14.
Emilio got a score of 311.9; this version has a mean of 259 and a standard deviation of 23.
Morgan got a score of 7.9; this version has a mean of 7.3 and a standard deviation of 0.5.

If the company has only one position to fill and prefers to fill it with the applicant who performed best on the aptitude test, which of the applicants should be offered the job?

Answer:

Vincent and Reyna.

Step-by-step explanation:

To compare the performance of three potential employees, we have to convert each score into z score.  

Vincent got 83.5 for a N(68.2, 99)

Z score for Vincent =

Kaitlyn got 251.2 with N(238, 22)

Z score for Kaitlyn =

Reyna got a score of 8.04 for N(7.27, 0.7)

Z score for Reyna =

Z score higher is a better option since all z scores are positive

Hence here Reyna is a good option.

The angle the golfer went off line from the tee when they  drove the ball

is \phi=28.2 \textdegree because the cosine rule has been applied to calculate the angle

From the question we are told that:

Distance of hole from tee d_h=340yards

Distance to the right d_r=230yards

Ball distance from hole d_b=175 yard

Given that the three points form a triangle x,y,z respectively

Where

d_h=xz

d_r=xy

d_b=yz

Using Cosine Rule

yz^2=xy^2+xz^2-2(xy)(xz)cos\phi

Therefore

cos\phi=\frac{yz^2}{xy^2+xz^2-2(xy)(xz)}

cos\phi=\frac{(175)^2}{230^2+340^2-2(230)(340)}

cos\phi=0.88

\phi=28.2 \textdegree

In conclusion the angle the golfer went off line from the tee when they

drove the ball is mathematically deducted and give as

\phi=28.2 \textdegree

pashok25 [27]

Answer:

The answer is 68°

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • A right angled-triangle IGH.
  • where, m∠G = 90°
<h3><u>To </u><u>Find</u>;</h3>
  • m∠I = ?

We know that

tan θ = Opp ÷ Adj

tan θ = 5 ÷ 2

tan θ = 2.5

tan θ = 68.2 ≈ 68

We know that tan 68 = 2.5

Thus, The m∠I is 68°
