Answer:
Set builder notation: {a | a ≥ -21}
Interval notation: [-21, ∞)
Step-by-step explanation:
A set represents a collection of things, objects, or numbers. A set builder notation is in the form y = {x | x is an odd number between 8 and 10}, which means y contains all the odd numbers between 8 and 10.
Interval notation is a way to define a set of numbers between a lower limit and an upper limit using end-point values. for example (8, 20) means numbers between 8 and 20.
Given -3a-15≤-2a+6; solving :
-3a - 15 ≤ -2a + 6
-3a + 2a ≤ 6 + 15
-a ≤ 21
dividing through by -1:
a ≥ -21
The solution is:
Set builder notation: {a | a ≥ -21}
Interval notation: [-21, ∞)

Step-by-step explanation:
Answer:
Domain is number of candy or 300
Range is profit from selling candy or $50
Step-by-step explanation:
Domain is the numbers you are allowed to use in your function. In this case, it would be the amount of candy you sold.
The range is the output from inputting the number(s) in the domain. In this case, the range is the amount of money you profit.
Profit=(amount gained)-(amount lost)
amount gained is from selling candy
amount lost is what you invested to get the candy
amount gained=(cost per candy)X(number of candy)
amount gained=(1.50)(300)
amount gained=$450
amount lost=$50
therefore
Profit=450-40=$400
a function for profit can be as follows:
P(x)=1.5x-c
where amount you sold each candy for, c is cost for those x candies, and P(x) is the profit for x candies

Step-by-step explanation:
6 is closer to 10
Answer:
a. As given in the question, some towns are located high in the Rockies above the sea level and some are located in the south-central valley of the California below the sea level as well. The meaningful zero does not exists here and the variable of interest is continuous(quantitative). Hence, the elevations can be best described as an interval data.
b. The unemployment rate can not be negative. Therefore, the meaningful zero exist here. Hence, the unemployment rate can be best described as ratio data.
