Mathematics
1 answer:
sesenic [268]3 years ago
7 0

Answer:

  0

Step-by-step explanation:

The sorted data set is ...

  1 2 3 3 5 7 8 9

The median is the average of the middle two numbers: (3+5)/2 = 4.

Replacing one of the 3s with a 1 makes the data set be ...

  1 1 2 3 5 7 8 9

The average of the middle two numbers is (3+5)/2 = 4.

The median increases by 4 - 4 = 0.

Please help with this question, thank you
Semmy [17]
Remark
The key step is just to subtract 5 from both sides. The pointed of the inequality still points away from the variable and towards the number. As long as that remains true, the correct answer can be found.

Solution
2.7 ≤ b + 5  Subtract 5 from both sides.
2.7 - 5 ≤ b
- 2.3 ≤ b      Write with the variable on the left.
b ≥ - 2.3  <<<< answer

Pleaseeeeeeeeeeeeee helppppppppppp
sergeinik [125]

Answer:

Step-by-step explanation:

8) (5x + 23) + (17x - 41) = 180

                             22x = 198

                                  x = 9

      arc JK    5(9) + 23 = 68°

     arc MJ    17(9) - 41 = 112°

     arc LMK  360 - 112 = 248

9) 8x + (21x - 12) + (10x + 9) + 90 = 360

                                             39x = 273

                                                  x = 7

                    arc WX    21(7) - 12 = 135°

                    arc YW    90 + 8(7) = 146°

                      arc YX    10(7) + 9 = 79°

                  arc VXW  360 - 8(7) = 304°
