Answer:
[tex]M = 4.67[/tex]
Step-by-step explanation:
Given
[tex]Data: 3, 7, 8, 12, 16, 18[/tex]
Required
The mean absolute deviation
Start by calculating the mean
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{3+ 7+ 8+ 12+ 16+ 18}{6}[/tex]
[tex]\bar x = \frac{64}{6}[/tex]
[tex]\bar x = 10.67[/tex]
The mean absolute deviation is then calculated using:
[tex]M = \frac{1}{n}\sum\limits^n_{i=1}|x _i - \bar x|[/tex]
So, we have:
[tex]M = \frac{1}{6}(|3 - 10.67| +|7 - 10.67| + |8 - 10.67| + |12 - 10.67| + |16 - 10.67| + |18 - 10.67|)[/tex]
[tex]M = \frac{1}{6}(|-7.67| +|- 3.67| + |-2.67| + |1.33| + |5.33| + |7.33|)[/tex]
Remove absolute brackets
[tex]M = \frac{1}{6}(7.67 +3.67 + 2.67 + 1.33 + 5.33 + 7.33)[/tex]
[tex]M = \frac{1}{6}*28[/tex]
[tex]M = 4.67[/tex]

What is the range of the function graphed below?
Answer:
[tex]-\infty < y < -2[/tex]
Step-by-step explanation:
Given
The attached graph
Required
The range of the graph
From the graph we can see that the curve points down towards the y-axis,
This means that y starts from a [tex]-\infty[/tex] number
Coming up, the curve stops increasing at 2 and becomes horizontal; This means that y ends at 2
Hence, the range is: [tex]-\infty < y < -2[/tex]

Answer:
12.2h + 18.2 yd^2.
Step-by-step explanation:
Surface area = 2hl + 2hw + 2lw where h = height, w = width and l = length.
= 2 * 2.6h + 2 * 3.5h + 2*2.6*3.5
= 5.2h + 7h + 18.2
= 12.2h + 18.2.

what is the average rate of change of f(x) = (x + 3)2 − 2
Answer:
When we have a function f(x), the average rate of change in the interval (a, b) is:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
In this case, we have the function:
f(x) = (x + 3)^2 - 2
(but we do not have the interval, and I couldn't find the complete question online)
So if for example, we have the interval (2, 4)
The average rate of change will be:
[tex]r = \frac{(4 + 3)^2 - 2 - (2 + 3)^2 + 2}{4 - 2} = \frac{24}{2} = 12[/tex]
If instead, we want the rate of change in a differential dx around the value x, we need to differentiate the function (this is way more complex, so I will define some rules first).
Such that the rate of change, in this case, will be:
f'(x) = df/dx
For a function like:
g(x) = x^n + c
g'(x) = n*x^(n - 1)
And for:
h(x) = k( g(x))
h'(x) = k'(g(x))*g'(x)
So here we can write our function as:
f(x) = k(g(x)) = (x + 3)^2 - 2
where:
g(x) = x + 3
k(x) = x^2 - 2
Then:
f'(x) = 2*(x + 3)*1 = 2*x + 6
That is the rate of change as a function of x (but is not an "average" rate of change)
Find the length of the unknown side.
25 cm
15 cm
Answer:
b = 20 cm.
Step-by-step explanation:
Define and explain:
This is a right triangle, so the Pythagorean Theorem applies.
The Pythagorean Theorem states that the sum of the squared legs will equal the squared length of the hypotenuse.
The legs of a triangle are the sides that form the right angle.
The hypotenuse is the longest side; the hypotenuse is always diagonal from the small square indicating a right angle.
Solve:
[tex]a^2+b^2=c^2[/tex]
[tex]a,b-legs[/tex]
[tex]c-hypotenuse[/tex]
[tex]15^2+b^2=25^2[/tex]
[tex]225+b^2=625[/tex]
[tex]625-225=400[/tex]
[tex]b^2=400[/tex]
[tex]b=20[/tex]
Conclude:
Therefore, the length of the unknown side is 20 centimeters.

Step-by-step explanation:
Given:
[tex]\frac{AD}{DC}=\frac{BE}{EC}[/tex]
To Prove:
AB║DE
Solution:
Since, corresponding sides of ΔACB and ΔDCE are proportional,
[tex]\frac{AD}{DC}=\frac{BE}{EC}[/tex]
Both the triangles will be similar.
ΔACB ~ ΔDCE [By SAS property of similarity]
Therefore, ∠1 ≅ 2 [CPCTC]
Since, ∠1 and ∠2 are the corresponding angles
Therefore, AB║DE [Converse of corresponding angles theorem]

HELP HELP HELP HELP ...
Answer:
A - since the median can be any number we know of. B - Again the median can be any number we know of, since it is a undetermined amount. E - The range can be 10 flights, this is because it is not a determiend value, and it is possible for the value to be 10.
Step-by-step explanation:
Wrong answer reasoning:
The mode doesnt need to be 9 if there is more than 1 mode, so that isnt it. Eliminating D. The mean can most definatly be determinded if we know the values. This elimnates C. The mean can be 6.875, but we dont know, so we can assume it IS 6.875. This eliminates F.

Chloe wants to buy a shirt at the store that cost $14.99. She also wants to
buy a pair of shoes that cost $25.99. She has a coupon for x dollars off her
entire purchase. She spends a total of $30.98 at the store. Which equations
could be used to find the value of the coupon, X. Choose all that apply. *
14.99 + 25.99 - X
14.99 + 25.99 - X = 30.98
40.98 - x = 30.98
14.99 - X + 25.99 = 40.98
Answer:
14.99 + 25.99 - X = 30.98
14.99 + 25.99 - X

True or False: y = x2 + 3 is a function.
A. True
B. False

Step-by-step explanation:
Answer:
A. true
Step-by-step explanation:
Can anyone tell me what the answer to this problem is and the explination?
The figure shown above is triangle. The area of the triangle is a= 1/2base times height.
Base is 10 . The height is 6.
A= 1/2bh
A= 1/2*10*6
A= 1/2*60
A= 30
Or you can find the area of the triangle separately and add them up.
First triangle :
The half of the base is 10/2= 5
B= 5 H= 6
A= 1/2*6*5
A= 15
Second triangle :
b= 5
h= 6
a= 1/2*5*6
a= 15
Add up them both areas 15+15= 30

Answer:
a. Area = 1,017.36 cm²; Circumference = 113.04 cm
b. Area
c. Circumference
Step-by-step explanation:
Given:
Radius (r) = 18 cm
π = 3.14
a. Area of the mirror = area of circle = πr²
Plug in the values
Area = 3.14*18²
Area = 1,017.36 cm²
Circumference = 2πr
Circumference = 2*3.14*18
Circumference = 113.04 cm
b. The area of the glass would be used in finding the amount of glass needed caused it's the surface of the glass that is to be replaced.
c. The silver wire would be placed around the mirror, therefore, it is the circumference that would be needed in finding the amount of wire needed since the circumference is the perimeter round the mirror.
