Which measure of variation should you use to describe
two data sets that are both not symmetric?

Step-by-step explanation:

s(n) = 2n - 5  

                  What is the sum  1st and 6th terms of the sequence?  12

s(1) = 2(1) - 5           =   -3

s(2) = 2(2) - 5         =   -1

s(3) = 2(3) - 5         =    1

s(4) = 2(4) - 5         =   3

s(5) = 2(5) - 5         =   5

s(6) = 2(6) - 5         =   7       add these numbers

Answer:

-4±2√3

Step-by-step explanation:

quadratic formula: (-b±√(b²-4ac))/(2a)

a = 1

b = 8

c = 4

(-8±√(8²-4*1*4))/(2*1)

(-8±√(64-16))/(2)

(-8±√48)/(2)

(-8±4√3)/(2)

-4±2√3

2.2 laps is a 1 1/2 mile race.

When a driver or a runner makes one trip around the track i.e. one full circle it is called lap.

Given a lap around a track is 2/5 of a mile.

1 lap =2/5 mile

x lap = 11/2 mile

x lap =(11/2) ÷(2/5)

x lap = 11/5 or 2.2

Thus 2.2 laps is a 1 1/2 mile race.

Step-by-step explanation:

.......................................

Answer:

Step-by-step explanation:

x²-8x+16+y²+2y+1=16+1-13
(x-4)²+(y+1)²=2²

general form of a circle's equation is
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r= radius
By comparing with A,
(4,-1) is center and radius= 2.

The center of the circle is (-4,2) and the radius is 2

The equation is given as:

x^2 + y^2 - 8x + 2y + 13 = 0

Rewrite as:

x^2 - 8x + y^2  + 2y + 13 = 0

Subtract 12 from both sides

x^2 - 8x + y^2  + 2y = -13

Group each variable

[x^2 - 8x] + [y^2  + 2y] = -13

-------------------------------------------------------------------

Take the coefficient of x and y

-8 and 2

Divide by 2

-4 and 1

Square both numbers

16 and 1

-------------------------------------------------------------------

Next, we add 16 and 1 to both sides of the equation

[x^2 - 8x + 16] + [y^2  + 2y + 1] = -13 + 16 + 1

Express as perfect squares and evaluate the sum

(x - 4)^2 + (y + 1)^2 = 4

Express 4 as 2^2

(x - 4)^2 + (y + 1)^2 = 2^2

A circle is represented as:

(x - a)^2 + (y - b)^2 = r^2

Where:

Center = (a,b)

Radius = r

This means that the center of the circle is (-4,2) and the radius is 2

Step-by-step explanation:

Answer:

x² + 10x + 25 = 31

Step-by-step explanation:

To complete the square use half the x coefficent (10/2 = 5)

and square it (5² = 25)

Then add it to both sides

x² + 10x + 25 = 6 + 25

x² + 10x + 25 = 31

Answer:

x^2 + 10x + 25 = 31

Step-by-step explanation:

x^2 + 10x + (10/2)^2 = 6 + 25

x^2 + 10x + 25 = 6 + 25

x^2 + 10x + 25 = 31

The first step requires a bit of explanation. The way to complete the square is to take 1/2 the linear term (10x) and square it

1/2 10 = 5

5 squared = 25

That number must be added to the right side to maintain equality.

Answer:

52 cm²

Step-by-step explanation:

There are 3 distinct faces:

one with sides 2 and 3

one with sides 2 and 4

one with sides 3 and 4

There are two of each distinct face (they are accros each other)

so we find their areas (we times by two as there are two of each face)

2×3×2=12

2×4×2=16

3×4×2=24

Finally we add the values:

12+16+24=52 cm²
