Answer:
A manufacturing machine has a 40% defect rate. If 131 items are chosen at random, then:
- The random variable, X=Number of 131 randomly selected items that are defective.
- Number of Items, n=131
- The point estimate of defective items, p=40%=0.4
<u> </u><u>{x | x ≤ 4.5} </u><u> is another way to represent this </u><u>solution set.</u>
- 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.

If the drawing of your octagon (or whatever) has been separated into triangles, and one triangle's area<span> is labeled, then you do not need to know the apothem. Just take the </span>area<span> of that one triangle, and multiply by the number of sides in the original </span>polygon<span>.</span>
Answer:
4u+16
Step-by-step explanation:
first multiply the outside bumber(in this case its 4) by each of the numbers and variables inside. (making u turn into 4u) and ( making 4 turn into 16 bcs 4x4=16
