Assume 2 numbers 500,500.. with a mean of 500
so if we add 10 to each of the two numbers, mean will be:
Of course you can vary the set and the numbers and still get the same mean
Answer:
1. False 2. True
Step-by-step explanation:
For a geometric sequence,
1. The sequence is :
3, 13, 23, 33,...
It is not geometric. It is false
2. The sequence is :
5, -25, 125, -625
So, the sequence is geometric as the common ratio is same. It is true.
Answer:
See picture attached
Step-by-step explanation:
The problem is really asking 5/6 divides by 1/6. This yields 5. Hope this helps!<span />
21+45+70=136
136+(2+x)=180
First subtract 136 from both sides
(2+x)=44=M<ROS
Subtract 2 from both sides
x=42
