Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Tobias got a score of 74.7; this version has a mean of 61.7 and a standard deviation of 13. Norma got a score of 351; this version has a mean of 291 and a standard deviation of 25. Vincent got a score of 7.38; this version has a mean of 6.9 and a standard deviation of 0.4. 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:
Norma performed best on the aptitude test and should be offered the job.
Step-by-step explanation:
We are given that three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Tobias got a score of 74.7; this version has a mean of 61.7 and a standard deviation of 13. Norma got a score of 351; this version has a mean of 291 and a standard deviation of 25. Vincent got a score of 7.38; this version has a mean of 6.9 and a standard deviation of 0.4.
Now, to find which of the applicants should be offered the job, we have to find the z-score of each of the applicants, and the one who gets the highest z-score will get the job.
The z-score probability distribution for the normal distribution is given by;
Z = [tex]\frac{X-\mu}{\sigma}[/tex] ~ N(0,1)
where, [tex]\mu[/tex] = mean and [tex]\sigma[/tex] = standard deviation
Firstly, we will find the z-score for Tobias;
The z-score of 74.7 = [tex]\frac{X-\mu}{\sigma}[/tex]
= [tex]\frac{74.7-61.7}{13}[/tex] = 1
Now, we will find the z-score for Norma;
The z-score of 351 = [tex]\frac{X-\mu}{\sigma}[/tex]
= [tex]\frac{351-291}{25}[/tex] = 2.4
Now, we will find the z-score for Vincent;
The z-score of 7.38 = [tex]\frac{X-\mu}{\sigma}[/tex]
= [tex]\frac{7.38-6.9}{0.4}[/tex] = 1.2
As we can clearly see that the z-score is highest for Norma which means that Norma performed best on the aptitude test and should be offered the job.

A square pyramid and cube are shown below. Name the two dimentional figure that is a cross section of the cube but not the pyramid.
Octagon
Square
Triangle
Rectangle
Answer: Square
The cross section of a cube would be a square, because cubes are made of 2D squares. The cross section of a pyramid would be triangles because they are made of a top with triangles.
The answer is square. Hope this helps!
Answer: The answer is Square.
A cube has sides constructed as 2 Dimensional squares. A pyramid has cross sections of triangles, so they do not have the same shape as a cross section. The answer is square.

8. At the fabric store, Marisela spends $9.00
on 1 1/8yards of fabric. How much does one
yard of fabric cost?
Answer:
6.55
Step-by-step explanation:
We know that 11/8 yards of fabric cost 9$
We need to first find what 1/8 yard of fabric costs
So you do 9/11 which gives the amount of 1/8 which is 0.818181812 and multiply that by 8 to find what the cost of one yard equals
What is the equation of the line that passes through the point (8,-8) and has a slope of -1
Answer:
y= (-1)*x
Step-by-step explanation:
lets assume that the line equation is
y=m*x +b
where m is the slope and b the independent variable that intercept Y axis.
then replacing the value of m:
y=(-1)*x + b
after that we have to look for the value of b. Its obtained replaicing the given point (8,-8):
-8 = (-1)*(8) +b
-8 = -8 + b
0 = b
Therefore the equation of the line is:
y= (-1)*x
Y=2(x-1)^2+1 in standard form
Answer:
2(x^2+1-2x)+1=
2x2+2-4x+1=
2x2-4x+3

the estimated world population in 2011 was 7 x 10^9. Of the total population, 682 million of those people were left handed. Approximately what percentage of the world population is left handed according to the 2011 estimation
Answer:
9.7 %
Step-by-step explanation:
estimated world population in 2011 = 7x10⁹
left handed = 682,000,000
find:
Approximately what percentage of the world population is left handed according to the 2011 estimation
percentage = left handed population
total population
= 682,000,000
7,000,000,000
= 0.682
7.0
= 9.7 %
Answer:
9.7%

solve for x: 3(2x+54)-(27x-3)=56
Answer:
x = 109/21
Step-by-step explanation:
Step 1: Write equation
3(2x + 54) - (27x - 3) = 56
Step 2: Solve for x
Distribute: 6x + 162 - 27x + 3 = 56Combine like terms: -21x + 165 = 56Subtract 165 on both sides: -21x = -109Divide both sides by -21: x = 109/21Which situation is best represented by the following
equation?
2x + x = 21
Answer:
If your solving for x then its x=3 because you combine liked terms then divide both sides by 3.
If the fraction 408/x-10 is equivalent to -24 find the value of x

What happens to the oxygen released during photosynthesis?
A. The oxygen atoms react with hydrogen atoms and produce water
molecules
B. The oxygen atoms are released from the atmosphere into space.
C. The oxygen atoms diffuse through the atmosphere and are
inhaled by animals.
D. The oxygen atoms diffuse through the atmosphere and are reused
as a reactant for photosynthesis.
Answer:
I believe your answer is C, the oxygen atoms diffuse through the atmosphere and are
inhaled by animals.
Step-by-step explanation:
Plants take in water that later splits to create hydrogen and oxygen. Since plants don't need oxygen, it gets released into the atmosphere for us and other animals to breathe.

The smaller angle = 20
The larger angle = 70
Step-by-step explanation:
1/4 of a circle is 90 degrees
90 = 10x+ 20x+30
Combine like terms
90 = 30x+30
Subtract 30 from each side
90-30 = 30x+30-30
60 = 30x
Divide each side by 30
60/30 = 30x/30
2= x
10x = 10*2 = 20
20x+30 = 20*2 + 30 = 30+30 = 70
Help me please what is the answer for this
