Answer:
-1 , -1.75, 3/11, 0.3
Step-by-step explanation:
Negatives are always less then positive, so they would go first since its least to greatest.
7/9 = 0.77 which means -1 7/9 = -1.77, therefore it is less then -1.75
-1.75 would be next
3/11 = 0.2 which is less then 0.3 so it would go next.
and at last, goes 0.3 as the greatest number.
Answer:
Option C is incorrect.
Step-by-step explanation:
An infinite series is given by m + b, 2m + b, 3m + b, 4m + b, ... .
A) The above sequence is given by f(x) = mx + b for x = {1, 2, 3, ......}
For, x = 1, f(x) = m + b
For, x = 2, f(x) = 2m + b
.............
So, this is a valid definition of the above sequence.
B) The above sequence is given by f(x) = 2m + b + m(x - 2) for x = {1, 2, 3, ......}
For, x = 1, f(x) = 2m + b - m = m + b
For, x = 2, f(x) = 2m + b + 0 = 2m + b
.............
So, this is a valid definition of the above sequence.
C) The above sequence is given by for n = {1, 2, 3, ......}
For, n = 1,
For, n = 2,
.............
So, this is not a valid definition of the above sequence.
D) The above sequence is given by and
for n = {1, 2, 3, .........}
For, n = 1,
For, n = 2,
.............
So, this is a valid definition of the above sequence.
Therefore, option C is incorrect. (Answer)
