Simplifying
Y + -10 = 14
Reorder the terms:
-10 + Y = 14
Solving
-10 + Y = 14
Solving for variable 'Y'.
Move all terms containing Y to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + Y = 14 + 10
Combine like terms: -10 + 10 = 0
0 + Y = 14 + 10
Y = 14 + 10
Combine like terms: 14 + 10 = 24
Y = 24
Simplifying
Y = 24</span>
The sample of the population is 100 students since they acquired answers from students from middle school and high school, having 50 students each school. 50 + 50 = 100 students as the sample. The total population for either or both of the schools is/are undetermined.

Step-by-step explanation:
Answer:
Option 2: 1.5 is the correct answer.
Step-by-step explanation:
Given information is:
Mean = μ = $27
SD = σ = $5.50
A z-score simply tells us how far a selected data value from the mean is.
Z-score is denoted by z and is given by the formula:
Let x = $35.25
Putting the values of mean and SD we get,
The value of z-score for a price of $35.25 per barrel is 1.5
Hence,
Option 2: 1.5 is the correct answer.
