Answer:
the 4
Step-by-step explanation:
The correct answer for the question that is being presented above is this one: "<span>1,903.73."</span>
Solution:
(1) Multiply the percent favored to the Number surveyed
0.60 * 2700 = 1,620
0.55 * 1900 = 1,045
0.40 * 1000 = 400
So the total is 3,065
(2) Get the weighted mean:
Add the total percent favored = 0.66 + 0.55 + 0.41 = 1.61
Weighted mean = 3,065 / 1.61 = 1,903.73
Answer:
19

Answer:
The solution is (3, -3)
Step-by-step explanation:
5x + 2y = 9
2x - 3y = 15
Use elimination by addition/subtraction. Multiply the first equation by 3 and the second by 2, obtaining:
15x + 6y = 27
4x - 6y = 30
----------------------
19x = 57
This yields x = 3.
Substituting 3 for x into 5x + 2y = 9, we get 5(3) + 2y = 9, or
15 + 2y = 9, or
2y = -6
This yields y = -3.
The solution is (3, -3)
