Answer:

Step-by-step explanation:

Ok, this is an easy one. Step one: Find the Mean of the numbers by adding all the numbers 21, 45, 21, 14, 21, 28, 14, 24, and 28 which you will get according to my answer 220. Then you divide that by 9 since that there are 9 numbers listed above. When you divide you will get about 24.4 since you want it to be rounded to the neared tenth. Then you subtract 24.4 to all the number and when you get your answer, put the answer as |-3.4| for the first one so you will get a positive instead of a negative which is what we want. The second will be |20.6| which is 20.6 ans so on when we subtract. Then when you get all of that, you will need to add all those numbers and get a number and divide that by 9 because again there are 9 numbers. Now that you know that, you can do part b and c. Interpret means to depict something. For part C, you will need to use part A again and find the mean absolute deviation for part A again but without 45. And then explain the difference and how it affects the answer. To help with that, compare the 2 answers.

RSB [31]
Let us assume the length of a side of the square floor = x feet
Area of the square floor as given in the question = 320 square feet
Then
x^2 = 320
x^2 = (17.89)^2
Then
x = 17.89
   = 18 feet approx

From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the second option or option "B".

The washer in the image has an inner diameter of 1/4 inch. The outer diameter measures 3/4 inch, and the washer is 1/4 inch thic
Talja [164]

Answer:

  0.14 lb . . .  closest choice is 0.11 lb

Step-by-step explanation:

The inside and outside radii are 1/8 in and 3/8 in, respectively. Then the area of the top of the washer is ...

  A = π(R² -r²) = π((3/8)² -(1/8)²) = π(9/64 -1/64) = π/8 . . . square inches

The height of the stack of 5 washers will be 5×(1/4 in) = 5/4 in. So, the volume of material in the stack of washers is ...

  V = Bh = (π/8)(5/4) = 5π/32 . . . cubic inches

The weight of material is the product of volume and density, so is ...

  W = (5π/32 in³)(0.285 lb/in³) ≈ 0.1399 lb ≈ 0.14 lb

_____

<em>Comment on the question</em>

Since this answer does not correspond to any of the offered choices, we suggest you ask your teacher to work this out for you. We suspect they will have difficulty justifying any of the answer choices shown here. (0.11 lb corresponds to 4 washers, not 5.)
