Step-by-step explanation:
A scientist was interested in studying if students beliefs about illegal drug use change as they go through college. The scientist randomly selected 104 students and asked them before they entered college if they thought that illegal drug use was wrong or o.k. Four years later, the same 104 students were asked if thought that illegal drug use was wrong or o.k. The scientist decided to perform McNemar's test. The data is below. What is the proportion of students that thought that is was wrong after college? After College ( four years later) Before College O.K. Wrong O.K. 4 17 Wrong 18 65
The number of students that thought that is was wrong before college is 18+65=83
The total number of students is 104
The proportion of students that thought that is was wrong before college is

Answer:
V = -9
Step-by-step explanation:
-15V - 40 = 23 - 8V
The objective is to get V alone. To do this, first subtract -15V from both sides. Since -15V is a negative, subtracting it will be adding a positive.
-40 = 23 + 7V
Now that there is only one term with the variable V, subtract 23 from both sides.
-63 = 7V
Finally, divide both sides by 7 to get V completely isolated.
-9 = V.
The final answer is V = -9.
Answer:
