Ascientist was interested in studying if students beliefs about illegal drug use change as they go through college. a 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. are the assumptions met? after college before college o. k. wrong o. k. 4 17 wrong 18 65

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
