Answer:
Around 2397 Americans must be surveyed to get a margin of error of 2%.
Step-by-step explanation:
We are given the following in the question:
Proportion of US residents who thinks marijuana should be made legal = 48%
We have to construct a 95% confidence interval.
Margin of error = 2% = 0.02
Formula for margin of error =
Putting values, we get,
Thus, around 2397 Americans must be surveyed to get a margin of error of 2%.
Answer: x = -1 and y = 9
The two equations are:
-9x + 2y = 23
-4x -y = -3
Now find for x in the first equation...
-9x + 2y = 23
-9x = 23 - 2y
x = (23 - 2y)/-9
Now place this value of x in the second equation and find for y...
-4{(23-2y)/-9} - y = -3
-92 + 8y + 9y = -3 * -9
17y = 27 + 92
y = 119/17
y = 7
Now place the value of y in the first equation," -9x + 2y = 23 " and find x
-9x + 2*7 = 23
-9x + 14 = 23
-9x = 23-14
x = 9/-9
x = -1
There you go! Hope it helps

Answer:
Step-by-step explanation:
-3(3x - 4) = - 9x - 12 ...distribute thru the parenthesis
-9x + 12 = -9x - 12
-9x + 9x = -12 - 12
0 = -24 (nope)
