Answer:
9x^2(5y^2 + 2x).
Step-by-step explanation:
First find the Greatest Common Factor of the 2 terms.
GCF of 18 and 45 = 9
GCF of x^2 and x^3 = x^2.
The complete GCF is therefore 9x^2.
So, dividing each term by the GCF, we obtain:
9x^2(5y^2 + 2x).

Answer:
x = 6   y = 5
Step-by-step explanation:
<u><em>X VALUE</em></u>
3x+11 = 5x-1
12 = 2x
x= 6
<em><u>Y VALUE</u></em>
4y-1 = 19
4y = 20
y = 5
 
        
                    
             
        
        
        
Answer:
X = 3.02

The percent of students that are aged 19 years or more is determined as 84%.
<h3>One standard deviation below the mean</h3>
In a normal distribution curve 1 standard deviation below the mean is defined as follows;
- 1 std below mean : M - d = 16% 
M - d = 20.6 yrs - 1.3 yrs = 19.3 years ≈ 19 years
19 years or more will occur at (M - d) + (M) + (M + 2d) = 100% - (M - d)
                                                                                        = 100% - 16% 
                                                                                        = 84%
Thus, the percent of students that are aged 19 years or more is determined as 84%.
