then what you want to do is find how many are there together im gonna say small has 12 medium has 16 and large has 20

Next you want to subtracts 3 small boxes cause of defects 24-3=21

Then, you want to multiply what your numbers are.

21*12=252

12*12=144

5*20=100

Then add

252+144+100=496

What is the mean absolute deviation for 3 3 4 5 5 4
nikitadnepr [17]

Answer as a fraction = 2/3

Answer in decimal form = 0.667 (approximate)

=======================================================

Explanation:

The first thing we need is to find the mean. Add up the values to get 3+3+4+5+5+4 = 24. Then divide by n = 6 since there are 6 values.

24/n = 24/6 = 4

The mean is 4

Now subtract the mean from each value

  • 3-4 = -1
  • 3-4 = -1
  • 4-4 = 0
  • 5-4 = 1
  • 5-4 = 1
  • 4-4 = 0

Apply absolute value to each result so that the difference is not negative.

We get this new list: {1, 1, 0, 1, 1, 0}

Now compute the mean of that new list to get the final answer

1+1+0+1+1+0 = 4

4/n = 4/6 = 2/3 = 0.667 approximately

Evaluate f-2g for f = 3 and g = 27.
lyudmila [28]
If you would like to evaluate f - 2 * g for f = 3 and g = 27, you can do this using the following step:

f - 2 * g = 3 - 2 * 27 = - 51
The correct result would be - 51.

If you would like to evaluate x * 0 + y * 0 for x = 3 and y = 2, you can do this using the following step:

x * 0 + y * 0 = 3 * 0 + 2 * 0 = 0 + 0 = 0
The correct result would be 0.

Part C: The saving using company B for 6 windows is $3.

Step-by-step explanation:

Part A:

Company A: (total charges) = ($6)x(N number of windows)+($12)

Company B: (total charges) = ($5)x(N number of windows)+($15)

Part B:

Company A for 8 windows: 6*8+12=$60

Company B for 8 windows: 5*8+15=$55

Part C:

(Saving) = (6*6+12)-(6*5+15)=48-45= $3
