2 x e x f = e x 2 x f = f x 2 x e
The mean of the scores to the nearest 10th
Score Number of Students is 59.
We have given a data,
80,85,6,90,95,100,6,8
What is the meaning of mean?

The number of of test scores=8
mean
Mean=59
Answer:
the savings is 6000
Step-by-step explanation:
We are told that the ratio of savings to expenditure is 2: 8, that is, that person saves 2 when he spends 8.
They tell us to find the savings when the cost is 24,000, so we are left with:
24000 * 2/8 = 6000
which means that when 24000 are spent the savings is 6000
