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 = ~ N(0,1)
where, = mean and = standard deviation
Firstly, we will find the z-score for Tobias;
The z-score of 74.7 =
= = 1
Now, we will find the z-score for Norma;
The z-score of 351 =
= = 2.4
Now, we will find the z-score for Vincent;
The z-score of 7.38 =
= = 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.
Answer:
So the answer is going to be B. AKA 22.5

Answer: x = 58°
Step-by-step explanation:
Sine = opposite leg ÷ hypotenuse
We need to find the hypotenuse first with the Pythagorean theorem.
a² + b² = c²
5² + 8² = c²
25 + 64 = c²
89 = c²
√c² = √89
c = 9.43398
c ≈ 9.43
Sine = opposite leg ÷ hypotenuse
Opp. leg - 8
Hypotenuse - 9.43
To find this, you have to use the calculator
Make sure the calculator is on scientific
If your calculator is on your computer and in full screen, find 8 ÷ 9.43 and then click sin⁻¹, you should get 58.03334
If your calculator is on your computer in mini screen, find 8 ÷ 9.43. This time, click the arrow that looks smth like this: ↑
When you do that, you should be able to see sin⁻¹, so you click that and you'll also get 58.03334
58.03334 ≈ 58
x = 58°
Hope I helped! Sorry I took so long
Answer:
P(A n B) = 0
Step-by-step explanation:
Given
Traces of TNT detected
No traces of TNT
Required
Probability of false positive
From the question, we understand that A and B must occur to get a positive and the result is 0.
The probability of A and B is represented as: P(A n B)
Include the result (0), we get:
P(A n B) = 0
