The other end point is 0,4
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%.

3 kL = 3000 L so 30000 L is bigger
Answer:
Step-by-step explanation:
Isolate x on one side of the equation.
2(-2x-4) ← (Expand by using with distributive property.)
<u><em>DISTRIBUTIVE PROPERTY</em></u>
⇒ A(B+C)=AB+AC
⇒ A(B-C)=AB-AC
A=2
B=(-2x)
C=4
2(-2x)-2*4
-2*2x-2*4
-2*2x-2*4 (Solve.)
-2*2-2*4=-4x-8
Rewrite the equation problem.
10-x=-4x-8
10-x-10=-4x-8-10 (Subtract 10 from both sides.)
Solve.
-x=-4x-18
-x+4x=-4x-18+4x (Then, add 4x from both sides.)
3x=-18 (Solve.)
3x/3=-18/3 (Divide by 3 from both sides.)
-18/3 (Solve & Simplify.)
-18/3=-6
X=-6
Therefore, the correct answer is x=-6.
Step-by-step explanation:
<em>Perimeter </em><em>of </em><em>a </em><em>rectangle</em><em>=</em><em> </em><em>2</em><em>L</em><em> </em><em>+</em><em> </em><em>2</em><em>W</em>
<em>let </em><em>the </em><em>length </em><em>be </em>2x-1<em> </em><em>and </em><em>breadth</em><em>/</em><em> </em><em>width </em><em>=</em><em> </em>3x+5
52= 2x-1 + 3x+5
52= 5x +4
<em> </em><em>collect </em><em>like </em><em>terms</em><em>;</em>
52-4 = 5x
48=5x
