To Solve MAD or the mean absolute deviation what you need to do is get the Mean so lets say  you have the numbers 20,35,18,34,60,82,10, and 29 add them up to get 228. next divide by the amount of numbers 228/8 = 36 now to get the mean absolute deviation get the difference of each number, but some will be negative so we will turn them to positive Like so.
20-36=-16 turn to positive 16
36-35=1
36-18=18
36-34=2
60-34=24
82-34=46
36-10=26
and 36-29=7
you add up these numbers to get 140 then divide them by the numbers 140/8=17.5
<span>so 17.5 is your mean absolute deviation.</span>

Which shows one way to determine the factors of x3 11x2 – 3x – 33 by grouping? x2(x 11) 3(x – 11) x2(x – 11) – 3(x – 11) x2(x 11
Aloiza [94]

The one way to determine factors of x³  + 11x² – 3x – 33  will be x^2(x+11)-3(x+11)_.

<h3>What is a factorization?</h3>

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The steps involved in the factorization are;

1. For each pair of parentheses, we create a common factor.

2. We use x2 as a common factor for the first parenthesis.

3. We use common factor 3 for the second parenthesis.

x^3  + 11x^2 - 3x -33 \\\\ x^2(x+11)-3(x+11)_

We will find the final solution as x^2(x+11)-3(x+11)_.

Hence the one way to determine factors of x³  + 11x² – 3x – 33  will be x^2(x+11)-3(x+11)_.

Can someone please help.
zvonat [6]

Answer:

  • 8 jars

Step-by-step explanation:

Let the number of jars is x.

<u>80 liters distributed, each jar has:</u>

  • 80/x

<u>Redistribution with 4 less jars, each jar now has:</u>

  • 80/(x - 4)

<u>Each jar has now twice the amount:</u>

  • 80/x*2 = 80/(x - 4)
  • 2/x = 1/(x - 4)
  • 2(x - 4) = x
  • 2x - 8 = x
  • x = 8

She prepared 8 jars at the start
