Answer:
D)the time (in hours) a 4-year-old spends unsupervised per day
Step-by-step explanation:
Given that 4-year-olds in a certain country average 3 hours a day unsupervised and that most of the unsupervised children live in rural areas, considered safe
X - the time (in hours) a 4-year-old spends unsupervised per day
X is N(3,1.8)

<u>Step-by-step explanation:</u>
To eliminate the exponent, apply log to both sides. This allows the exponent to become the coefficient, which can then be divided from both sides.
![x^y=P\\\\log\ x^y=log P\\y\cdot log\ x=log\ P\\\large\boxed{log\ x=\dfrac{log\ P}{y}}](https://tex.z-dn.net/?f=x%5Ey%3DP%5C%5C%5C%5Clog%5C%20x%5Ey%3Dlog%20P%5C%5Cy%5Ccdot%20log%5C%20x%3Dlog%5C%20P%5C%5C%5Clarge%5Cboxed%7Blog%5C%20x%3D%5Cdfrac%7Blog%5C%20P%7D%7By%7D%7D)
Answer:
No, they are not.
Step-by-step explanation:
The easiest way to find a function on a graph is by finding if any points share the same x value. All of these do, so none are functions.
