Answer:
The mean of the given set of numbers is 3.5
Step-by-step explanation:
We need to find the mean of following numbers:
8.9, 6.1, -4.8, 8.2, 2.7,-0.1
For calculating the mean the formula used is: [tex]Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}[/tex]
Finding sum of numbers:
[tex]Sum \ of \ numbers= 8.9+6.1-4.8+8.2+2.7-0.1\\Sum \ of \ numbers= 21[/tex]
Total numbers = 6
So, mean is:
[tex]Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}\\Mean=\frac{21}{6}\\Mean= 3.5[/tex]
So, mean of the given set of numbers is 3.5

Each week jake gets an allowance of $8 plus $3 for each chore he does at
home. His younger sister bella gets an allowance of $6 plus $2 per each chore
she does. Write an expression for how much their parents give them each week if
they do the same number of chores.
Answer:
y = 5x + 14
Step-by-step explanation:
y represents the total money their parents give them. X represents the number of chores. 5 is the sum of 3 + 2 since Jack gets $3 for each chode while Bella gets $2 for each chore. 14 is the set amount of money the receive each week since 8 + 6 is 14.

the question is on the sheet.
area of the whole figure
= (x + 1)(2x + 3)
= x(2x + 3) + 1(2x + 3)
= 2 {x}^{2} + 3x + 2x + 3
= (2x)^(2} + 5x + 3
area of the unshaded region
= x(2x)
= 2x²
area of the shaded region
= 2x² + 5x + 3 - 2x²
= (2x² - 2x² ) + 5x + 3
= 5x+ 3
THEREFORE,
THE AREA OF THE FRAME IS C. 5x + 3

It takes 404040 ink cartridges and 200200200 pages to print a book, and it takes 303030 ink cartridges and 808080 pages to print a magazine. Sarah wants to print books and magazines with at most 300300300 ink cartridges and 120012001200 pages. Let BBB denote the number of books she prints and MMM the number of magazines she prints.
Answer:
40B +30M ≤ 300
200B +80M ≤ 1200
Step-by-step explanation:
The inequality functions are as follows:
For 40 cartridges per book and 30 cartridges per magazine and at most 300 cartridges are used
So the function would be
40B +30M ≤ 300
Now the another would be
There are 200 pages for printing a book and 80 pages are required for printing a magazine also she used at most 1,200 pages
So, the function would be
200B +80M ≤ 1200
