1 9/100
= 1 + 9/100
= 1/1 + 9/100
= (1/1 * 100/100) + 9/100
= 100/100 + 9/100
= 109/100
= 109 ÷ 100
= 1.09

Step-by-step explanation:
68–95–99.7 Rule : It also known as the empirical rule and it is a shorthand used to calculate the percentage of values that lie within a range around the mean in a normal distribution with the width of several standard deviation
μ = π = sample proportion
= 44 %
= 0.44
Population standard deviation proportion,

Answer:
x = 12
Step-by-step explanation:
Solve for x:
(3 x)/4 = 9
Multiply both sides of (3 x)/4 = 9 by 4/3:
(4×3 x)/(3×4) = 4/3×9
4/3×3/4 = (4×3)/(3×4):
(4×3)/(3×4) x = 4/3×9
4/3×9 = (4×9)/3:
(4×3 x)/(3×4) = (4×9)/3
(4×3 x)/(3×4) = (3×4)/(3×4)×x = x:
x = (4×9)/3
9/3 = (3×3)/3 = 3:
x = 4×3
4×3 = 12:
Answer: x = 12
