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.

Please help! !!!!!!50 POINTS!!!!!!! Question bellow!!
Sergeeva-Olga [200]
Area = πr²
Area = 3.14* 6²
A = 3.14 * 36
A = 113.04

Now find the area of the other one. 

<span>Area = πr²
A = 3.14 * 0.75</span>²
A = 1.76625

Now subtract them. 

113.04 - 1.76625 = 111.27375
Now, we have our answer: A = <span>111.27375

However, I don't see why they told you to have an exact answer for the area. You can't have an exact answer when you use 3.14 for pi.</span>
