Find the mean absolute deviation for the set below:
62, 71, 83, 110, 501, 94, 227
Answer:
(MAD) mean absolute deviation: 114.2
Step-by-step explanation:
Mean: 62 + 71 + 83 + 110 + 501 + 94 + 227 = 1,148/7 = 164
164 - 62 = 102
164 - 71 = 93
164 - 83 = 81
164 - 110 = 54
164 - 501 = 337
164 - 94 = 70
164 - 227 = 63
Mean Absolute Deviation: 102 + 93 + 81 + 54 + 337 + 70 + 63 = 800/7 = 114.2
Answer:
Step-by-step explanation:
First, add all the numbers and count the total amount of numbers.
Once you've done that find the mean by dividing the total of the numbers by how many numbers you have.
Next make a chart, have 2 parts in the chart. Make boxes for however many numbers you have. Make another row in the chart for the distance from the mean ( how many numbers is it from the mean.)
Add all the "distance from mean" numbers and divide by total numbers, If a decimal, round up or down.
Then, you have the M.A,D ( Mean Absolute Deviation )

If the volume of the pyramid is 72 centimeters cubed, what is its height in cm?
A rectangular pyramid with a base of 6 centimeters by 4 centimeters and a height of h.
A) 3
B) 9
C) 12
D) 18
Answer:
Well, Your best answer will be is B) 9.
Because,
The volume of the pyramid is:
v = (w × h × l)/3
Then, We have to values together:
72 = (4 × 6 × h)/3
Well, Then we have to solve the h:
72 × 3 = (4 × 6 × h)/3 × 3
216 / 6 = (4 × 6 × h)/6
36/4 = (4 × h)/4
9 = h
So, The best answer will be is 9.
Good Luck!~

The height of the pyramid is 9 cm.
What is a pyramid?A pyramid is a structure where outer surfaces are triangular and converge to a point at the top.
The volume of a pyramid with a square base is given as:
Volume = 1/3 x base area x height
We have,
The volume of a rectangular pyramid is given by the formula:
V = (1/3)Bh
Where B is the area of the base and h is the height.
In this case,
The base has dimensions of 6 cm by 4 cm, so its area is B.
= 6 cm x 4 cm
= 24 cm².
We are given that the volume of the pyramid is 72 cm³, so we can plug in these values to get:
72 cm = (1/3)(24 cm²)(h)
Simplifying this equation.
72 cm³ = 8 cm² x h
9 cm = h
Therefore,
The height of the pyramid is 9 cm.

Step-by-step explanation:
Answer:
Step-by-step explanation:
(10-2)×(8+7) can be simplified to (8) × (15) = 120.
Another way of doing this problem is to apply the distributive property:
(10-2)×(8+7) = 80 + 70 - 16 - 14 = 150 - 30 = 120
For what values of b will F(x) = logo x be an increasing function?
A. b< 1
B. b> 1
C. b>0
D. b< 0
Answer:
A b(1
Step-by-step explanation:
Using logarithmic function concepts, it is found that for values of b > 1, [tex]f(x)=log_{b}x[/tex] will be an increasing function.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A logarithmic function is modeled by:
[tex]f(x)=log_{b}x[/tex]
The coefficient b determines the behavior of the function, as follows:
b > 1: The function is increasing.
b < 1: The function is decreasing.
Using logarithmic function concepts, it is found that for values of b > 1, [tex]f(x)=log_{b}x[/tex] will be an increasing function.
Hence, for values of b > 1, [tex]f(x)=log_{b}x[/tex]will be an increasing function.

What’s the volume of the composite figure?
What is the measure of an angle, in degrees, if its supplement is six times its complement?
Answer:
72 degrees.
Step-by-step explanation:
We can name the measure of the angle x.
We can name the measure of the complement of it y.
Note that complementary angles add up to 90 degrees and supplementary angles add up to 180 degrees.
Using this info, we can set up two equations.
x+y=90
x+6y=180
Subtract the first equation from the second to eliminate x. You can do both ways, but I prefer to keep the equation positive.
x+6y=180
-x -y -90
5y=90
Divide both sides by 5.
y=18
The complement is 18, now we can plug that in to find x.
x+18=90
Subtract 18 from both sides.
x=72
The measure of the angle is 72 degrees.

Tom found out that 3 L of fruit punch serves 8 people. He wants to make enough for 48 people. How many liters of punch does he need
Answer:
18
Step-by-step explanation:
Use a proportion
[tex]\frac{3}{8}[/tex]=[tex]\frac{x}{48}[/tex]
8*6=48
So if we multiply 3*6, we get how many liters it takes to serve 48 people
3*6=18
The answer would be 18 L
You do this by doing 48/8= 6
The reason you do 48 / 8 is because you you want to find out how many liters you need so if a 3L serves 8 people you would have to divid 48 into 8. (hope that makes since)
6 x 3 = 18L
Then take the 6 and times that by the 3 getting a total of 18 liters
(Hope this makes since :D)
