A. yes, the data represents a function because u have no repeating x values. A function cannot have repeating x values...they can have repeating y values, just not the x ones.
B. table : (8,8)(12,12)(14,16)(16,16)
look at ur points...when x = 8, y = 8...so the table, when x = 8 has a
value of 8
relation : f(x) = 8x - 5....when x = 8
f(8) = 8(8) - 5
f(8) = 64 - 5
f(8) = 59....and the relation has a value of 59
Therefore, the relation has a greater value when x = 8 <==
C. f(x) = 8x - 5...when f(x) = 19
19 = 8x - 5
19 + 5 = 8x
24 = 8x
24/8 = x
3 = x <==
Probability P(D and C) is (C) 1/2.

What is probability?</h3>
- Probability is the branch of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely it is that a claim is true.
- The probability of an event is a number between 0 and 1, with 0 indicating impossibility and 1 indicating certainty.
To find the probability P(D and C):
According to the task content;
- The total number of students in the class is; 300.
- The number of students who have a cat and a dog is 150.
On this note, the probability, P(D and C) is given as;
- P(D and C) = 150/300 = 1/2
Therefore, probability P(D and C) is (C) 1/2.

The correct question is given below:
300 students in a high school freshman class are surveyed about what kinds of pets they have. Of the 300 students, 200 have a dog, 180 have a cat, and 150 have a cat and a dog. Using this information, answer each of the following questions.
Let D be the event that a randomly selected student has a dog and C be the event that a randomly selected student has a cat.
What is P(D and C), the probability that a student in the class has a dog and a cat?
A) 2/3
B) 3/5
C) 1/2
D) 5/6
Answer:
Step-by-step explanation:
120 x .6 =72
120-72 = 48
48x .6 = 28.8
72+28.8 = 100.8
