From a population of size 400, a random sample of 40 items is selected. the median of the sample group of answer choices must be 200, since 400 divided by 2 is 200 must be 10, since 400 divided by 400 is 10 must be equal to the median of population, if the sample is truly random none of these alternatives is correct.

400+40+200+400 +200 +10+400×2+10

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
