Since x=1 produces y=3 and y=20, the relation (1,3),(1,20),(9,4) is not a function.
The relation is not a function.
The second graph is correct. Because the first equation is <= -x-1, it must fall under that line: only the second and fourth graphs do so. The second equation, >=2x+4, means it must fall above that line: only the second and third graphs do so.
Answer:
Probability that a student who passed the test did not complete the homework = 0.07
Step-by-step explanation:
Given:
Total number of students = 28
Number of students who passed the test = 18
Number of students who completed the assignment = 23
Number of students who passed the test and also completed the assignment = 16
To find: probability that a student who passed the test did not complete the homework
Solution:
Probability refers to chances of occurrence of some event.
Probability = number of favorable outcomes/total number of outcomes
Let A denotes the event that students passed the test and B denotes the event that students completed the assignment
P(A only) = 
Here,

So,

Therefore,
probability that a student who passed the test did not complete the homework = 0.07
Answer:
$544
Step-by-step explanation:
To determine the original price of the DVD player considering that you know that it had a 75% reduction, you can use a rule of three as the price of $136 represents 25% of the original price and with this you can calculate the price that represents 100%:
$136 → 25%
x ← 100%
x=(136*100)/25=$544
According to this, the answer is that the original price of the DVD player was $544.
