Answer:
The new mean is: 11.8
Step-by-step explanation:
Given the data set
2.4 1.6 3.2 0.3 1.5
Sum of terms = 2.4 + 1.6 + 3.2 + 0.3 + 1.5 = 9
Number of terms = 5
We know that the mean of a data set is the sum of the terms divided by the total number of terms, so
Mean = Sum of terms / Number of terms
substituting Sum of terms = 9 and Number of terms = 5
= 9/5
= 1.8
Thus, the Mean = 1.8
We need to determine the mean when each piece of data is increased by 10.
All we need is to add 10 in the determined mean to determine the new mean.
New Mean = Mean + 10
= 1.8 + 10
= 11.8
Therefore, the new mean is: 11.8
<u>VERIFICATION:</u>
When each piece of data is increased by 10
so,
The equation is an illustration of a linear function
The parts of the equation are:
- The amount of money Angelique saved: 60
- Number of stickers Angelique bought: s
- Total number of stickers Angelique can buy: 20
- The cost of one sticker: 3
- Number of stickers Angelique can buy with her remaining money: 20 - s
- The amount of money spent on some stickers: 3s
A linear function can take any of the following representations
- Point slope form
.
- Slope intercept form
.
In the above representations of linear functions
- m represents the slope or rates
- b represents the y-intercept or the initial value
- x and y represent the corresponding input and output values
Using the above forms and their interpretations, we have the following submission
- 60 represents the amount of money Angelique saved
- s represents the number of stickers Angelique bought
- 20 represents the total number of stickers Angelique can buy
- 3 represents the cost of one sticker:
- 20 - s represents the number of stickers Angelique can buy with her remaining money
- 3s represents the amount of money spent on some stickers:
