Well because if you use 1,000 you know since 10 has 1 zero, you take 1 zero from 1,00 and it becomes 100.
Answer:
The mean for the combined sample = 6.
Step-by-step explanation:
We have been given that one sample of n = 10 scores has a mean of M = 8.
So the sum of 10 scores for 1st sample will be:
We are also told that second sample of n = 5 scores has a mean of M = 2.
So the sum of 5 scores for 2nd sample will be:
When the both samples are combined, so total points will be: and total scores will be .
Therefore, the mean for the combined sample will be 6.
8000000- you can only have 1 number so that is it.
Answer:
p=2
Step-by-step explanation:
10 – (8p + 3) = 9(2p - 5)
(rearrange and distribute) -8+7=18−45
(Subtract and combine) −26=−52
(Divide and find p) p=2
