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)
The equation that can be used to find the number of points is 9 + (14 × x) = 331 and the value is 23.
<h3>How to illustrate the information?</h3>
From the information, Sonia has completed 14 levels of a video game and has 9 points so far in her current level and she has a total of 331 points.
Let the number of points earned be illustrated as x.
The equation that can be used to find the number of points she earned for completing each level will be:
9 + (14 × x) = 331
9 + 14x = 331
14x = 331 - 9
14x = 322
Divide
x = 322 / 14
x = 23
The number of points is 23.
