What does "Mean" mean?
Is this even a question!!!!🤨🤨
Ans:
Mean is the average value of a data set, found by summing all values and dividing by the number of data points.

Find the Mean of the question, Put your answer into nearest tenth.
1) 12, 10, 24, 32, 6, 56
Solution:
First add all the data numbers.
Then divide it by 6
So you will get your MEAN!!
MEAN = 23.3

Find the Mean Absolute Deviation of the following test scores:
- 87, 94, 72, 65, 97, 7
Work:
Write the data in the first column of the table.
Then Calculate the mean of the data and write that in each cell of column 2.
Subtract column 1 from column 2 and write the difference in column 3.
Rewrite all the numbers from column 3 as positive numbers in column 4.
Calculate the mean of the data in column 4, and you’re done! This is the MAD.
MAD= 22.9

Tell whether the function p(x) = 5(1.2x) shows
growth or decay.
p(x) = 5(1.2 x)
The base , 1.2, is greater than 1. This
is an exponential growth function.
