Answer:
8/3 or 2 2/3
Step-by-step explanation:
Each recipe is 1 1/3 >insert unit< of flour but he's baking two recipes. So, you multiply 1 1/3 by 2 to get 8/3, or 2 2/3
Answer:
x = 3/2
Step-by-step explanation:
x- 3/4 + 2/3 = 17/12
x = 17/12 + 3/4 -2/3
x = 3/2
If the original population has a Normal distribution, then the distribution of the sample mean is also Normal.
If we extract random samples of size n from a population with half a μ and standard deviation σ, then the distribution of the sample mean will have the following parameters:
μ_Xbar = μ
σ_Xbar = σ/ √(n).
Where:
μ = 50
σ = 4
n = 20
So:
μ_Xbar = 50
σ_Xbar = 0.8944
F(x) = 1.25(38 - x)
Finding the inverse of a function:
y = f(x)
y = 1.25(38 - x)
Solve for x:
y = 1.25(38 - x)
y/1.25 = 38-x
x = 38 - y/1.25
Switch x and y.
y = 38 - x/1.25
f^-1(x) = 38 - x/1.25
