Answer:
2(m + [n)] + [1]
Step-by-step explanation:
(2m) + (2n + 1) =
= 2m + 2n + 1
= 2(m + n) + 1
= 2(m + [n)] + [1]
Answer:
if it is arithmetic, ach item us increase linearly. The general term is - 175+100(n-1)
where n is the number of term.
the 4th term is 125
if it is geometic, each item us increased exponetially. T he general term is 25/9 x 3^(n-1)
where n is the number of term
the 4th term is 75
The equation that passes through these points is x = 4
Answer: 306
Step-by-step explanation:
Formula to find sample size:
, where = standard deviation, E = margin of error, z* = critrical z-value.
As per given,
Critical z-value for 99% confidence = 2.576
Now , the minimum sampl size :
Hence, the required sample size = 306
Answer:
n < -14
Step-by-step explanation:
6 (n+2) < -72
6n + 12 < -72
6n < -72 - 12
6n < -84
n < -84/6
n < -14
