To solve for the minimum score required, we find for the z
score value at P = 0.97 (top 3%). The z score is:
z = 1.88
Then we use the formula to find for X:
z = (X – u) / s
1.88 = (X – 400) / 100
X = 588
<span>You have to score at least 588.</span>
Answer:
Both expressions equal 5 when substituting 2 for x because both expressions are equivalent
Step-by-step explanation:
Given
- Expression 1
-- - Expression 2
Required
Find the result of both expressions when ![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
<em>Expression 1</em>
![\frac{1}{2}x + 4](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dx%20%2B%204)
Substitute ![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
![\frac{1}{2} * 2 + 4](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2A%202%20%2B%204)
![1 + 4](https://tex.z-dn.net/?f=1%20%2B%204)
![Result = 5](https://tex.z-dn.net/?f=Result%20%3D%205)
<em>Expression 2</em>
![x + 6 - \frac{1}{2}x - 2](https://tex.z-dn.net/?f=x%20%2B%206%20-%20%5Cfrac%7B1%7D%7B2%7Dx%20-%202)
Substitute ![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
![2 + 6 - \frac{1}{2} * 2 - 2](https://tex.z-dn.net/?f=2%20%2B%206%20-%20%5Cfrac%7B1%7D%7B2%7D%20%2A%202%20-%202)
![2 + 6 -1 -2](https://tex.z-dn.net/?f=2%20%2B%206%20-1%20-2)
![Result = 5](https://tex.z-dn.net/?f=Result%20%3D%205)
Answer:
No.
Step-by-step explanation:
1. Since 19 is a prime number, it only has two factors: 1 and 19. Therefore, 3 is not a factor of 19 because no natural number multiplied by 3 equals 19.
