I googled it and got that
Answer:
D
Step-by-step explanation:
First put the data from smallest to largest
12 points, 17 points,21 points, 23 points, 24 points, 28 points,29 points
The left end of the whisker should be 12 (This eliminates graph a)
The right end of the whisker should be 29 (This eliminates graph b)
There are 7 points
The middle point is 4
The 4th point is 23
That is the line in the middle of the box (This eliminates graph c)
The lower line of the box is at at point 2 = 17
The upper line of the box is at point 6 = 28
This leaves us with graph D
4x - 3y + 20 = 0....4x - 3y = -21
4x - 3y = -21.....multiply by -2
5x - 6y = -25
----------------
-8x + 6y = 42 (result of multiplying by -2)
5x - 6y = -25
---------------add
-3x = 17
x = -17/3
this system of equations has 1 solution
Answer:
x = 6
Step-by-step explanation:
6(9+x) = 5(3x)
6*9 + 6*x = 5*3x
54 + 6x = 15x
54 = 15x - 6x
54 = 9x
x = 54/9
x = 6
check:
(9+6)/(3*6) = 5/6
15/18 = 5/6
92 x 0.1 + 68 x 0.2 + 81 x 0.7
= 9.2 + 13.6 + 56.7
= 79.5%
