- A set is open if every point in is an interior point. A set is closed if it contains all of its boundary points.
What is open set example?
- An open subset of R is a subset E of R such that for every x in E there exists ϵ > 0 such that Bϵ(x) is contained in E.
- For example, the open interval (2,5) is an open set. Any open interval is an open set. Both R and the empty set are open.
What is an example of a closed set?
- The simplest example of a closed set is a closed interval of the real line [a,b].
- Any closed interval of the real numbers contains its boundary points by definition and is, therefore, a closed set.
- The closed interval [1,4] contains the limit points 1 and 4 so it is a closed set.
Then number-line shows a closed dot at 4.5. This shows that x is a number that is less than or equal to 4.5.

They're all equal. They would all be $87.
To find, divide each price by the number of tires.
Answer:
10 pounds.
Step-by-step explanation:
In this scenario, we can use the Rule of Three to solve for the whole weight of the stew. This rule is used for ratio problems. You simply need to multiply the available diagonal values together and then divide by the remaining value to get the value of the single variable in the ratio. Like so...
40% <=====> 4 pounds
100% <=====> x pounds
(100 * 4) / 40 = x pounds
400 / 40 = x pounds
10 = x pounds
Finally, we can see that the total weight of the stew if she followed the original recipe would be 10 pounds.
Answer:
6.77ft
Step-by-step explanation:
Answer:
180°, ∠4, ∠5
Step-by-step explanation:
∠1+∠2+∠3 = 180° because, as seen, their sum makes a straight angle. (on the transversal E)
∠2 is equal to ∠4 because of the Alternate Interior Angles theorem
∠1 is equal to ∠5 because of the Corresponding Angles theorem
