In a vacancy for a position of animal breeder in an organization, then criteria of selection were work experience, entrance exam, and interview results. The relative importance of these criteria was regarded to be different. The weights of these criteria and scores obtained by 3 candidates (out of 100 in each criterion) are given in the following table. In addition, the selection of a candidate is based on the average result on these criteria, (full question attached)
Answers
Answer:
To determine the most suitable candidate we will calculate their total scores and see who's the best.
first for mr X
work experience = 70
score = work experience x wieght = 70 x 4 = 280
Entrance = 78
score = 78 x 3 = 234
Interview = 70
score = 70 x 4 = 210
total score = 280 + 234 + 280 = 794
for mr Y
Work experience = 89
score = 89 x 4 = 356
Entrance = 83
score = 83 x 3 = 249
Interview = 89
Score = 89 x 4 = 356
Total score = 356 + 249 + 356 = 961
for mr Z
work experience = 85
score = 85 x 4 = 340
Entrance = 89
Score = 89 x 3 = 267
Interview = 85
Score = 85 x 4 = 340
Total score = 340 + 267 + 340 = 947
So as we can see Mr Y has best score therefore I think he's the best for the job.
Explanation:
[tex]\sf Average \ Result : \dfrac{sum \ of \ value \ of \ scores}{sum \ of \ weight}[/tex]
Workout:
[tex]\sf For \ candidate \ X = \dfrac{70 \ \cdot \ 4 \ + 78 \ \cdot \ 3 \ + 70 \ \cdot \ 4 }{4 + 3 + 4} = 72.18 \ \ average \ score[/tex]
[tex]\sf For \ candidate \ Y = \dfrac{89 \ \cdot \ 4 \ + 83 \ \cdot \ 3 \ + 89 \ \cdot \ 4 }{4 + 3 + 4} = 87.36 \ \ average \ score[/tex]
[tex]\sf For \ candidate \ Z = \dfrac{85 \ \cdot \ 4 \ + 89 \ \cdot \ 3 \ + 85 \ \cdot \ 4 }{4 + 3 + 4} = 86.09 \ \ average \ score[/tex]
Conclusion:
Among all of them, candidate Y has the best average score of about 87.36 whereas candidate Z has second best score of 86.09 average score and candidate X has the least average score of 72.18.
Candidate Y is the appropriate candidate for this position on the criteria.

If 80% of a number is 288 and 95% of the same number is 342, find 15% of that
number.
Answers
Answer:54
Step-by-step explanation:
There are quicker ways to solve this but a simple and easy way to do this would be by dividing your number by the percent so 288/80 and with this, you would get your number for 1 percent or 3.6. Now you can multiply that number by the percent your need to find so 15. And 15 x 3.6 is = 54.
Camacho is buying a monster truck. The price of the truck is x dollars, and he also has to pay a 13%, percent monster truck tax. Which of the following expressions could represent how much Camacho pays in total for the truck?
Answers
Thank you for asking this question. Here is your answer:
We will consider the price of the truck to be $x
And the amount of tax in the percentage would be 13%
13/100
= $ 0.13x (this is the actual amount of the tax)
Now we will calculate the total price of the truck =
$x + $ 0.13x
= $ x(1 + 0.13)

The length of the AC is x^2 + 4x - 12.
What is a parallelogram?That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
Given :
In Parallelogram ABCD, diagonals AC and BD intersect at point E.
such that
AE = x^2 - 12,
CE = 4x
We know that the diagonal of a parallelogram bisect each other.
x^2 - 12 = 4x
x^2 - 4x - 12= 0
(x-6)(x-2) = 0
Hence, the value of x = 6, 2.
AC = AE + CE = x^2 + 4x - 12.

The measure of the third angle in the ΔABC is 70 degrees
Complete questionIn ΔABC, m∠2 = 70 and m∠1 = 40, find the measure of all third angle of ΔABC.
How to determine the third angle?The given parameters are:
m∠2 = 70
m∠1 = 40
The sum of angles in a triangle is:
m∠1 + m∠2 + m∠3 = 180
So, we have:
70 + 40 + m∠3 = 180
Subtract 110 from both sides
m∠3 = 70
Hence, the measure of the third angle in the ΔABC is 70 degrees

the unsimplified fraction is 4/12
if wanted simplified version its 1/3

The Z-score is 2.306 to three decimal places. However, the Z-test statistic value shows that it is greater than the Z-critical value, so we reject the null hypothesis [tex]\mathbf{H_o}[/tex]
What is the Z-score of a test statistic?A z-score is a measurement of how often standard deviations the score obtained from a z-test is beyond or under the mean population.
From the given data information, let us find the mean and the standard deviation.
[tex]\mathbf{Mean (\bar x) = \dfrac{1154+5998+1007+...3987+4187+887}{10}}[/tex]
[tex]\mathbf{Mean (\bar x) = \dfrac{24256}{10}}[/tex]
Mean (x) = 2425.6
The hypothesis testing can be computed as:
[tex]\mathbf{H_o: \mu = 2425.6}[/tex]
[tex]\mathbf{H_1: \mu \ne 2425.6}[/tex]
The standard deviation (σ) is:
[tex]\mathbf{=\mathbf{ \sqrt{\dfrac{(1154-2425.6)^2+....+(887-2425.6)^2}{10-1}}}}[/tex]
[tex]\mathbf{= \sqrt{3199489}}[/tex]
= 1788.71
Now, the Z-test statistic is determined using the formula:
[tex]\mathbf{|Z| = |\dfrac{\bar x - \mu }{\sigma}| }[/tex]
[tex]\mathbf{|Z| = |\dfrac{2425.6 -6550 }{1788.71}| }[/tex]
[tex]\mathbf{|Z| = |-2.3058| }[/tex]
Z ≅ 2.306
Therefore, at a 0.05 level of significance, the Z-critical value is 2.306. However, since the Z-test statistic value shows that it is greater than the Z-critical value, so we reject the null hypothesis [tex]\mathbf{H_o}[/tex]

Each day that a library book is kept past its due date, a $0.30 fee is charged at midnight. Which ordered pair is a viable
solution if x represents the number of days that a library book is late and y represents the total fee?
Answers
The equivalent equation to find the ordered pair will be y=0.3x where x represents the number of days the book is late and y represents the total fine fee.
A linear equation is an equation where the highest degree in the equation is 1.
for example, y=mx,
where y and x is the variable and m, is the constant.
Given, that the librarian charges $0.30 per each day that the book is late to submit
for estimating the relation between the number of days the book is late and the total fine fee
Let's assume the number of days the book is late is x,
and the total fine is y
the librarian charges $0.30 per one day
so for x days, the total charge will be =0.30x
so from above, it is clear that the linear equation will be
y=0.3x
applying all the order pairs in this equation we can decide.
The equivalent equation to find the ordered pair will be y=0.3x
