It might be A but I'm not 100% sure inequalities was my worst thing I learned in algebra 2<span />
Answer:
In geometry, a polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit. The solid plane region, the bounding circuit, or the two together, may be called a polygon.
The segments of a polygonal circuit are called its edges or sides, and the points where two edges meet are the polygon's vertices(singular: vertex) or corners.
So, if a shape has points where two edges meet, it is indeed a polygon. Some examples include: Equilateral Triangles, Squares, Regular Pentagons, Regular Hexagons, Regular Heptagons, and Regular Octagons.
The correct answer for this problem is A.
Answer:
<h3>√(1-a)²+(b+2)²</h3>
Step-by-step explanation:
If the pipe on the plan runs from point N(a, -2) to point P(1, b), the expression that represents the shortest distance between N and P in units, is expressed using the formula;
D = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinates N(a, -2) and P(1, b);
x₁ = a, y₁ = -2, x₂ = 1 and y₂ = b
NP = √(1-a)²+(b+2)²
<em>Hence the expression that represents the shortest distance between N and P in units is √(1-a)²+(b+2)² units</em>
Answer:
We can be 95% confident that consumers spend between $4.04 and $15.96 less at Store A than the consumers spend at Store B.
Step-by-step explanation:
Confidence Intervals give an estimate as range of values for a statistic concerned at a <em>confidence level</em>.
In this case the statistic is the mean difference between Store A and Store B purchase amounts and the confidence level is 95%.
Confidence Interval can be calculated using M±ME where
- M is the sample mean difference between Store A and Store B purchase amounts
- ME is the margin of error from the mean
