Answers
The pair of variables would most likely have a positive association are follow:
- The age of a kitten and it's weight
- Temperature and sales of ice cream
- The number of notebooks bought and the total cost
What is Positive association?
Two variables have a positive association when the values of one variable tend to increase as the values of the other variable increase
Here,
- Age of a kitten and it's weight
- Temperature and sales of ice cream
- Number of notebooks bought and the total cost
There are positive association pairs because when the values of one variable tend to increase as the values of the other variable increase
Hence, the pair of variables would most likely have a positive association are follow:
- Age of a kitten and it's weight
- Temperature and sales of ice cream
- Number of notebooks bought and the total cost

The area of a regular hexagon with an apothem of 16.5 inches and a side of 19 inches is Area of hexagon = 1/2(length of apothem)(perimeter of the hexagon) = 940.5 inches. (Option-B)
Apothem:
Apothem is a perpendicular line from the center of the regular polygon to one of its sides.
Area of Regular polygon with apothem:
Area = 1/2 x (length of apothem) x (perimeter of hexagon)
• Given,
apothem = 16.5 inches and length of a side =19 inches
• Perimeter = 6 x (side of a hexagon)
= 6 x (19)
= 114 inches
• Hence,
Area = 1/2 x (16.5) x (114) = 940.5 inches(rounded to the nearest tenth)

Answer: B. 940.5 square inches
==============================================
Explanation:
Any regular hexagon is really the combination of six identical (aka congruent) equilateral triangles glued together. If we can find the area of one triangle, then we multiply by 6 to get our final answer.
The apothem is the height of the equilateral triangle with the triangular base being the side length of the hexagon.
area of triangle = (1/2)*base*height
area of triangle = 0.5*(hexagon side length)*(apothem)
area of triangle = 0.5*19*16.5
area of triangle = 156.75
This is the area of one equilateral triangle. Having 6 triangles leads to a total area of 6*156.75 = 940.5 square inches

The absolute error is $1898, the relative error is 2
What is an absolute and relative error?
An absolute error is a determinant of how large an error is. A relative error defines how good or bad an error is.
The formula for determining an absolute error is;
- Absolute error = measured value - actual value
The formula for determining a relative error is:
- relative error = absolute error/actual value
From the parameters given:
The absolute error can be computed as:
Absolute error = 2944 - (2944 - 1898)
Absolute error = 2944 - 1046
Absolute error = $1898
The relative error = 1898/1046
The relative error = 1.8
The relative error ≅ 2 (as an integer)

Answer and Step-by-step explanation:
A system of equations is a group of equations that need to be manipulated in some way that will figure out the values of the variables.
The most common system of equations seen is a system of linear equations, which means that the degree of the variables is no more than 1. These can be solved using elimination, substitution, or even graphing, if applicable.
Hope this helps!
Answer:
A system of equations is 2 or more equations that need to be solved. When you solve a system of equations, the answer is where the equations intersect on a graph. Sometimes there is 2 solutions (equations intersect twice), 1 solution (equations intersect once), no solution (equations don't intersect), or infinite solutions ( equations are the same).
They are usually solved using substitution, elimination, or simply looking at a graph to see where the lines intersect.
Some examples:
2x+3y=15
x-3y=3
y=x^2+1
2x-y= -4
