Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below.
Demetria got a score of 71.471.4; this version has a mean of 66.666.6 and a standard deviation of 88.
Norma got a score of 258.3258.3; this version has a mean of 238238 and a standard deviation of 2929.
Kaitlyn got a score of 88; this version has a mean of 7.27.2 and a standard deviation of 0.40.4.
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?
Answers
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
[tex]z - score = \frac{ 71.4 - 66.6 }{ 8}[/tex]
= > [tex]z - score = 0.6[/tex]
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
[tex]z - score = \frac{ 258.3 - 238 }{ 29}[/tex]
= > [tex]z - score = 0.7[/tex]
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
[tex]z - score = \frac{ 8 - 7.2}{ 0.4}[/tex]
= > [tex]z - score = 2[/tex]
Now given that the z-score of Kaitlyn is the highest it means that performed best and should be given the job
The difference of 5 times a number and 3 equals 7.
What is the number?
Answers
Answer:
2
Step-by-step explanation:
The equation would be 5x - 3 = 7. "x" replaces "a number." First you would add 3 to both sides, simplifying to 5x = 10. Now, just divide 5 from both sides, getting the answer, x = 2. So, the number is 2. You can check your work by putting it back into the equation: 5(2) - 3 = 7 goes to 10 - 3 = 7 which goes to
7 = 7.

14. Solve the Quadratic equation by the
method of completing square 3x2 - 8x - 3
Answers
Answer:
x = -1/3 and x = 3
Step-by-step explanation:
I'm not sure, but I think you mean 3x^2 - 8x - 3 = 0
In that case:
1. Add 3 on both sides
3x^2 - 8x -3 + 3 = 3 -> 3x^2 - 8x = 3
2. Divide both sides by 3
x^2 - 8/3x = 1
3. Add ((8/3)/2)^2 to both sides
x^2 - 8/3x + ((8/3)/2)^2 = 1 + ((8/3)/2)^2
4. Simplify
x^2 - 8/3x + (4/3)^2 = 1 + (4/3)^2
x^2 - 8/3x + 16/9 = 1 + 16/9
5. Rewrite x^2 - 8/3x + 16/9 = 1 + 16/9 as a perfect square
and simplify 1 + 16/9
(x - 4/3)^2 = 25/9
6. Find the square root of both sides
[tex]\sqrt{ (x -4/3)^2} = \sqrt{25/9}[/tex]
7. Simplify
(x - 4/3) = ±5/3
8. Rewrite the equation as two seperate equations
(x - 4/3) = ±5/3 ->
a. (x - 4/3) = 5/3
b. (x - 4/3) = -5/3
9. Solve for x by isolating the variable (add 4/3 to both sides)
a. x = 5/3 + 4/3
b. x = - 5/3 + 4/3
10. Simplify
a. x = 9/3 -> x = 3
b. x = -1/3

y = mx + b
where m is the slope and b is the y-intercept.
The equation given to us is:
y = -3x - 2
Since the equation is in slope-intercept form, we can see that -3 is the slope and -2 is the y-intercept.
Answer choice d is correct.

Carlos plotted the points (-4,-4) and (0, 3) and connected them with a line, as shown below.
What is the slope between the two points?
Answers
Answer:
The slope between the two points is 7/4
Step-by-step explanation:
Slope of a Line
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points plotted by Carlos are (-4,-4) and (0,3), thus the slope is:
[tex]\displaystyle m=\frac{3-(-4)}{0-(-4)}[/tex]
