Answer:
x = 4 ± 
Step-by-step explanation:
Given
x² - 8x = 3
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 3 + 16
(x - 4)² = 19 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ±
Answer:
Step-by-step explanation:
A proportion could be used.
With 2 parts of compost and 6 parts potting soil, you would end up with 8 total parts.
So it can be written as a ratio of compost to total mix, or 
The problem states 10 kg are needed in total, and the variable would be the amount of compost
As a ratio it would be 
.
Use the ratios to write a proportion.
Multiply both sides of the equation by 10
Convert to a decimal if desired.

Answer:
12%
Step-by-step explanation:
We have to find percentage of employee both manager and has MBA degree.
Percentage of employee both manager and has MBA degree=P(MBA and manager)*100
We are given that
P(MBA)=0.25
P(Manager)=0.20
P(MBA/ manager)=0.60
P(MBA and manager)=?
P(MBA/ manager)=P(MBA and manager)/P(Manager)
P(MBA/ manager)*P(Manager)=P(MBA and manager)
P(MBA and manager)=0.6*0.2
P(MBA and manager)=0.12
Percentage of employee both manager and has MBA degree=0.12*100
Percentage of employee both manager and has MBA degree=12%.
Thus, the percentage of the employees is both manager and has MBA degree is 12%
