![3.2 \to 1\ digit](https://tex.z-dn.net/?f=3.2%20%5Cto%201%5C%20digit)
![Product \to 3\ digits](https://tex.z-dn.net/?f=Product%20%5Cto%203%5C%20digits)
Step-by-step explanation:
Given
![0.47 * 3.2 =](https://tex.z-dn.net/?f=0.47%20%2A%203.2%20%3D)
See comment for complete question
Required
The number of decimal places
To do this, we simply calculate the number of digits after the decimal points
![0.47 \to 2\ digits](https://tex.z-dn.net/?f=0.47%20%5Cto%202%5C%20digits)
![3.2 \to 1\ digit](https://tex.z-dn.net/?f=3.2%20%5Cto%201%5C%20digit)
The product is the sum of the digits above 2 + 1 = 3
Hence:
![Product \to 3\ digits](https://tex.z-dn.net/?f=Product%20%5Cto%203%5C%20digits)
They would be identical so it would be 114
Answer:
μy = $6.56 ; σy = 2.77
Step-by-step explanation:
Given the data :
Mean μx= $8.56
Standard Deviation σx ≈ 2.77
Profit, Y on pizza with current promo :
Price off on pizza = $2
Y = x - 2
μx = E(x) = $8.56
μy = μ(x - 2)
μy = μx - $2
μy = $8.56 - $2
μy = $6.56
For the standard deviation of y
σx ≈ 2.77
σy = σ(x - 2)
σy = σx - 2
Constants are treated as 0 for standard deviation
σy = 2.77
Answer:
