Step-by-step explanation:
Alissa will save $13.50 from the sale.
8+2x is the answer. The rest of these characters is for the >20 rule
The caret (^) is the symbol conventionally used to indicate an exponent.
You have
area = 2.76·10^12
width = 4.6·10^5
You want to find the perimeter of the rectangle with these dimensions.
The perimeter of a rectangle is twice the sum of length and width.
perimeter = 2*(length + width)
The length can be figured from the area using the formula for area.
area = length*width
area/width = length . . . . . . . . . divide by width
Filling in the numbers, we have
perimeter = 2*((2.76·10^12)/(4.6·10^5) +(4.6·10^5))
perimeter = 2*(6.0·10^6 +0.46·10^6)
perimeter = 2*6.46·10^6 = 1.292·10^7
The perimeter of the rectangle is ...
1.292·10^7
To find the axis of symmetry you must first find the vertex of the parabola. The formula for vertex is -b/2a. So the vertex has a "x" coordinate at 4/2 or 2. so the axis of symmetry is the vertical line x = 2

Step-by-step explanation:
Cluster sampling, is a form of sampling whereby the population is divided by the researchers into smaller groups that are referred to as clusters and then the sample will be taken from the clusters formed.
Convenience sampling is when a sample is drawn based on the available population.
Systematic sampling is when a sample is gotten when the members are taken at regular intervals e.g 5th person, 12th items etc.
Simple random sampling is when the sample is selected from the larger population and in this case, every member involved can be selected as they all have an equal chance.
Based in the definition above, the answers will be:
a. Cluster sample
b. Convenience sample
c. Systematic sample
d. Simple random sample
