The number two is a function
First rule of function: for each element of A there is one and only one element of B
For example, in the first one -5 is "collegated" to -2 and 3. So this isn't a function.
Naturally, every element of B can have more element of A
Answer:
27.5
Step-by-step explanation:
We can split it into to 2 rectangles so it would be 2.5x7.5 for 1 rectangle. You have to subtract 2.5 from 6 which is 3.5 so the second rectangle is 3.5x2.5.
Rectangle 1= 18.75
Rectangle 2= 8.75
18.75+8.75= 27.5
The closer the probability is to 1, the more likely it is to occur and the closer the probability is to 0, the less likely it is to occur.
<h3>Probability</h3>
This is the likelihood that an event will occur.
- Probability of an event occuring is calculated thus P(event) = event space/sample space.
- The event space is the set of desired outcomes in which the event can occur while the sample space is the set of all possible outcomes.
- Now, the probability P(x) of an event x is in the range 0 ≤ P(x) ≤ 1 where P(x) = 0 implies that the event cannot occur and P(x) = 1 implies that the event will definitely occur.
<h3>To draw conclusions about the likelihood that something will occur</h3>
- For an event will occur, it value must be close to 1.
- For example, a probability P(x) = 0.38 is less likely to occur than a probability P(x) = 0.78.
So, the closer the probability is to 1, the more likely it is to occur and the closer the probability is to 0, the less likely it is to occur.

Answer:
Dollars
Quantitative
Step-by-step explanation:
The units of measurement of variable of interest are Dollars because the calculated mean and standard deviation of the data set of variable of interest indicates the measurements constitutes of dollars. The type of data is quantitative because the data can be meaningfully represented as numerically.
