Step-by-step explanation:
Answer:
Let the number be x
Ratio states that as the comparison of sizes of two quantities of the same unit.
Given : Ratio 3:2
The first number be 3x and
the second number be 2x.
then,
As per the condition:
Combine like terms;
5x = 80
Divide both sides by 5 , to solve for x;
Simplify:
x=16
Then, the numbers are:
and
.
Therefore, the number 80 is divided in the ratio of 3:2 is, 48 and 32.
Answer:
μ ≈ 2.33
σ ≈ 1.25
Step-by-step explanation:
Each person has equal probability of ⅓.
The mean is the expected value:
μ = E(X) = ∑ X P(X)
μ = (1) (⅓) + (2) (⅓) + (4) (⅓)
μ = ⁷/₃
The standard deviation is:
σ² = ∑ (X−μ)² P(X)
σ² = (1 − ⁷/₃)² (⅓) + (2 − ⁷/₃)² (⅓) + (4 − ⁷/₃)² (⅓)
σ² = ¹⁴/₉
σ ≈ 1.25
