24/63= 0.38
the answer for this problem is 0.38
C: y= 6
Since they are varying inversely, as one gets larger the other gets smaller and vice-versa.
Since when y=3 when x=4.....
When x gets divided by two y would get multiplied by two instead
So y=6 when x=2
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
