Let x be a random variable with mean μ and standard deviation σ. then the skew of x can be defined as follows: x − μ 3 e[x3] − 3μσ2 − μ3 skew(x) = e σ = σ3 show that the exponential distribution is always skewed right by showing that for x ∼ exponential(λ) the skew is always positive regardless of λ.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
