Answer:

2.2

Step-by-step explanation:

If you find the mean of the deviation, you get 2.2

The mean absolute deviation of the data is M = 2.2

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the total number of points be n

Now , the value of n = 10

And , the number of points on each data is given by set A

Now , the value of set A = { 7 , 2 , 8 , 5 , 9 , 9 , 5 , 6 , 8 , 1 }

So , the total sum of data = 7 + 2 + 8 + 5 + 9 + 9 + 5 + 6 + 8 + 1

The total sum of data = 60

Now , the mean number of data points = 60/10 = 6

And , the mean deviation is M

M = 1/10 | [ ( 7  - 6 ) + ( 2 - 6 ) + ( 8 - 6 ) + ( 5 - 6 ) + | ( 9 - 6 ) | + ( 9 - 6 ) + ( 5 - 6 ) + ( 6 - 6 ) + ( 8 - 6 ) + ( 1 - 6 ) |

M = ( 1/10 ) [ 1 + 4 + 2 + 1 + 3 + 3 + 1 + 0 + 2 + 5 ]

M = ( 1/10 ) [ 22 ]

M = 2.2

Therefore , the value of M is 2.2

Hence , the mean deviation is 2.2

Answer:

204.2     square cm

Step-by-step explanation:

Area of the whole circle

PI x 9 squared =

PI x 81 = 254.4690...

Area whire circle

PI x 4 squared=

PI x 16 = 50.2654

        Subtract white circle from the whole circle

254.4654 - 50.2654 = 204.2035...

The required area of the two concentric circles is given as 204.20 square cm.

Given that,
The shaded area of the figure shown, correct to one decimal place is to be determined.

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
According to the question,
Area of the shaded area = 3.14 [9]²- 3.14[4]²
Area of the shaded area = 204.20 square.

Thus, the required area of the two concentric circles is given as 204.20 square cm.

Answer:

104

Step-by-step explanation:

104 is parallel to x meaning it would stay as 104 (this is what my school tought me sorry if its incorrect)

Answer:

[tex]6\pi[/tex] inches

Step-by-step explanation:

The area of a circle is [tex]\pi r^2[/tex].

Since [tex]\pi r^2=9\pi[/tex]

[tex]r^2=9[/tex]

And

[tex]r=3[/tex]

Since the radius is 3 inches,

the diameter would then be 6 inches. (3 * 2)

The circumference of a circle is [tex]\pi d[/tex], d being the diameter.

Hence, the circumference is [tex]6\pi.[/tex]

Answer:

Take the square root of each side

D (x+b/2a)  =±sqrt( (b^2-4ac)/ 4a^2)

Step-by-step explanation:

We have

(x+b/2a) ^2 = (b^2-4ac)/ 4a^2

We need to take the square root of each side to continue to isolate x

(x+b/2a)  =±sqrt( (b^2-4ac)/ 4a^2)

Answer:

195

Step-by-step explan

Answer:

195 yards

Step-by-step explanation:

remember a rectangle has 4 sides.

100 yards wide is how wide 1 side is. so 2 sides are 200 yards wide.

to determine the width you subtract 200 yards from  590 which give you the answer 390. finally to determine just one side of the length you need to divide 390 in two to get 195 yards.

I think the answer would be 40

Answer:  Hello, There! your Answer is Below

40 Is your Answer

Step-by-step explanation:

Step 1: Our output value is 80.

Step 2: We represent the unknown value with XStep 3:

From step 1 above,$80=100

Step 4: Similarly, x=50

Step 5: This results in a pair of simple equations:This results in a pair of simple equations:

$80=100\(1)

$x=50(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

80/x = 100%/50%

Step 7: Again, the reciprocal of both sides gives

x/80 = 50/100

x=40$

Therefore, 50%of 80i s 40

SURFACE AREA FORMULA IS 2πR( R + H)

Answer:

36degrees

Step-by-step explanation:

2x + 26 = 3x + 21

2x - 3x = 21 - 26

-x = -5

x = 5

m<B = (3x+21)°

m<B = 3(5) + 21

m<B = 15+21

m<B = 36degrees

Answer:

x≥−3

Step-by-step explanation:

Let's solve your inequality step-by-step.

−4x−10≤2

Step 1: Add 10 to both sides.

−4x−10+10≤2+10

−4x≤12

Step 2: Divide both sides by -4.

−4x /−4 ≤ 12 /−4

= x≥−3

Answer:

x ≥ -3

Step-by-step explanation:

you add 10 on both sides

-4x - 10 ≤ 2

      +10  +10

=   -4x ≤ 12

then you divide -4 on both sides to get the x by itself

12/-4 is -3

since you divided by a negative you flip the sign
