Answer:
35.71%
Step-by-step explanation:
So, let's determine the number of jobs the industry will have in 2030.
So, in 2020, the industry has 123,200 jobs.
Each year, the industry loses 4,400 jobs.
Thus, by 10 years in (2030), the industry would have lost (4,400)(10) or 44,000 jobs.
This means that in 2030, there will only be 123,200-79200 jobs left.
Now, percentage change is given by:
The new value is 79200 and the old value is 123,200. Substitute them:
Use a calculator. Simplify:
If the result is negative, then it's a decrease. Therefore, the percentage change from 2020 to 2030 is approximately 35.71%
The combination that denotes the empty set{∅} is motor ∩ bicycle.
<h3>What is a set theory?</h3>Set theory is the mathematical study of well-defined groups of things called elements of the set.
In the given Venn diagram, the elements in the set of Motor, Manual, and Bicycle are as follows:
- Motor = {8, 24}
- Manual = {24, 32}
- Bicycle = {44}
- The union of motor and manual i.e. Motor ⋃ Manual = {24}
The combination that represents an empty set {∅} is the intersection that occurred between motor and bicycle and can be expressed as:
= motor ∩ bicycle
This is because there are no set elements overlapping between motor and bicycle, this makes it an empty set{∅}.
