The mean absolute deviation of the list of numbers is 16.4. The correct answer is C.
To find the mean absolute deviation (MAD) of the list of numbers, we follow these steps:
Step 1: Calculate the mean (average) of the numbers in the list.
Mean = (34 + 12 + 49 + 8 + 2) / 5 = 105 / 5 = 21
Step 2: Find the absolute deviation for each number by subtracting the mean from each number and taking the absolute value.
Absolute Deviations: |34 - 21| = 13, |12 - 21| = 9, |49 - 21| = 28, |8 - 21| = 13, |2 - 21| = 19
Step 3: Calculate the average (mean) of the absolute deviations.
Mean of Absolute Deviations = (13 + 9 + 28 + 13 + 19) / 5 = 82 / 5 = 16.4
Therefore, the mean absolute deviation of the list of numbers is 16.4. The correct answer is C.

Answer:
360
Step-by-step explanation:
The formula is (n-2)180 -> 6(180) = 1080
1080/8=135
135 is the measure of one interior angle so the exterior has to equal 45 for one side.
45 x 8=360
The answer is 360

Find the surface area of the figure below.
Answer:
696.8 mm^2
Step-by-step explanation:
Well first lets find the bottom part of the square first.
13*13= 169
Thats the floor
13*5= 65
Thats 1 of the sides
there are 4 sides
65*4= 260
260+169= 429
Now find the triangle
(13*10.3) / 2
You’d get 66.95
66.95 *4 since there are 4 sides
You’d get 267.80
267.8+429= 696.8

how to solve 2x^2 - 4x = 3
Answer:
1 ± i(1/2)√2
Step-by-step explanation:
Write this quadratic in standard form: subtract 3 from both sides. This results in 2x^2 - 4x - 3 = 0. Let's apply the quadratic formula. The coefficients of the x terms are 2, -4 and -3, so the discriminant is (-4)^2 - 4(2)(-3), or 16 - 24 = -8.
Following the format of the quadratic formula, we get
-(-4) ±i2√8 4 ±i2√2
x = ----------------- = --------------- = 1 ± i(1/2)√2

of the box, and Bill has eaten
1
4
of the box of cereal. How many ounces are left in the box?
Answer:
2 ounces
Step-by-step explanation:
1 = 5/8 - 1/4 = 1/8
16 x 1/8 = 2 oz
Answer:
2 ounces left
Step-by-step explanation:
if anna ate 5/8 of the box, and Bill has eaten 1/4 of the box, then in total they’ve eaten 7/8 if the box (1/4 turns into 2/8 + 5/8)
1/8 of the box is left and 1/8 of 16 is 2. so 2 ounces would be left

In a quiz, positive marks are given for correct answers and negative marks are given for incorrect answers. If Jack's scores in five successive rounds were 25, -5, -10, 15 and 10, what was his total at the end?
Answer:
His total at the end is 35
Step-by-step explanation:
To get his total, we have to add what he had in each of the rounds together
We have this as;
25 + (-5) + (-10) + 15 + 10
= 50 - 15 = 35
An angle measures 32° less than the measure of its complementary angle. What is the
measure of each angle?
Answer:
First angle = x
Second angle = x - 32
We know that, complementary angles form => 90°
So,
[tex]x + x - 32= 90 \\ 2x = 90 + 32 \\ 2x = 122 \\ x = \frac{122}{2} \\ x = 61[/tex]
First angle,
=> x = 61°
Second angle
[tex]x - 32 \\ = 61 - 32 \\ = 29[/tex]
Second angle,
=> 29°
