Question

24.Find the mean of the following data 4, 4, 5, 7, 6, 7, 7, 12, 3.
25.Write two solutions of the linear equation x + 2y = 1​

Answer 1

Answer:

mean = 6.111111111...

x+2y = 1

x = -1 y = 1

x = 1 y = 0

Step-by-step explanation:

Mean = 4+4+5+6+7+7+7+12+3/9 = 6.111...

x+2y = 1

x = -1 y = 1

-1 + 2 x 1 = 1

-1 + 2 = 1

1 = 1

x = 1 y = 0

1 + 2 x 0 = 1

1+0 =1

1=1
