Explanation: First rewrite the ratio 3 : 12 as the fraction 3/12.

Next, we can find an equal ratio by

simply writing this fraction in lowest terms.

If we divide both the numerator and the denominator of 3/12

by their greatest common factor of 3, we get the equal ratio 1/4.

Now we can use 1/4 to find another equal ratio.

If we multiply both the numerator and denominator

of 1/4 by 2, we get the equal ratio 2/8.

So 3 : 12 is equal to 1 : 4 and 2 : 8.

Make sure to write your final answers as the same

form in the original problem.

Almost all companies utilize some type of year-end performance review for their employees. Human Resource (HR) at a university's
balu736 [363]

Answer:

The Answer is 76.

Step-by-step explanation:

Given the normal distribution " 10% of employees (rated) exemplary, 20% distinguished, 40% competent, 20% marginal, and 10% unacceptable'',  we can see that exemplary employees are top 10% rated employees.

We have the formula for normal distribution:

z=(X-M)÷σ

where z is the <em>minimum z-score </em>for top 10% employee, X is the <em>minimum </em>score for top 10% employee, M is the <em>mean</em> of the score distribution, σ is the <em>standard deviation</em> of the score distribution.

The z-score we are looking for is the value "a" that separates the highest 10% from the lowest 90% i.e. P(z≤a)=0.90

If we look at z-table, corresponding value for a is 1.28155

We can now put the values in the formula:

1.28155=\frac{X-50}{20}

So X=(1.28155×20)+50=75.631

Therefore minimum score for exemplary employee is 76.
