Descriptive statistics summarizes or describes the characteristics of a data set. Descriptive statistics consists of two basic categories of measures: measures of central tendency and measures of variability (or spread). Measures of central tendency describe the center of a data set.

Answer:

Step-by-step explanation:

DC=2-0=2

Or

DC=√[(2-0)²+(-2-(-2))²]=√[4+(-2+2)²]=√4=2

BC=(0-(-2))=2

Or

BC=√[(2-2)²+(-2-0)²]

=√[0+4]

=2

AB=√[(2-0)²+(0-4)²]

=√[4+16]

=√20

=2√5

Perimeter=2[DC+BC+AB]

=2[2+2+2√5]

=2[4+2√5]

=8+4√5 Units

Answer:

  ₹1000

Step-by-step explanation:

Let m represent the marked price. After the discount, the price is 0.80m. After the tax is added, the price is (0.80m)(1.13). This value is Rs 904, so the marked price is ...

  (0.80m)(1.3) = ₹904

  m = ₹904/(0.80×1.13) = ₹904/0.904

  m ≈ ₹1000

The marked price of the watch is ₹1000.

Answer:

24

Step-by-step explanation:

5x³ + x² – 10x

5(2)³ + (2)² - 10(2)

5(8) + 4 - 20

= 40 + 4 - 20

= 44 - 20

= 24

Answer:

the answer is 1 : 2.4 because for every 1 inch on the original image there are 2.4 inches on the modified image.

Step-by-step explanation:

Step 1:

Measure the change in X and Y of a single length of the original image.

X1 = 3.5

Y1 = 5

Step 2:

Measure the change in X and Y of the same length on the modified image.

X2 = 8.5

Y2 = 12.5

Step 3:

use formula SF = X2/X1 = Y2/Y1

(SF = Scale Factor Dilation)

(X2 and Y2 = change in X and Y of the same length on the modified image.)

(X1 and Y1 = change in X and Y of a single length of the original image.)

X2 = 8.5

8.5/X1

X1 = 3.5

8.5/3.5

8.5/3.5 = 2.4

2.4

1 : 2.4

Answer: 64.8

Step-by-step explanation:

60/100=1944/x (cross multiplication

(1944*100)/60 = 3240

2% of 3240 =

2/100 = x/3240

64.8

( this helps with percentage (%/100=is/of) and cross multiplication)

Answer:

(1 )= ..x = (2)

Step-by-step explanation:

(1) = x = (2)

Answer: 1 ≤ x ≤ 2

Step-by-step explanation:

Given inequality

3 ≤ 6x - 3 ≤ 9

Add 3 on all sides

3 + 3 ≤ 6x - 3 + 3 ≤ 9 + 3

6 ≤ 6x ≤ 12

Divide 6 on all sides

6 / 6 ≤ 6x / 6 ≤ 12 / 6

[tex]\boxed{1}[/tex] ≤ x ≤ [tex]\boxed{2}[/tex]

Hope this helps!! :)

Answer:

x = 17.6

Step-by-step explanation:

We know that a quadrilateral will have a total of 360 degrees. We can create an expression and solve for x.

5x + 7x + 3x + 6 + 90 = 360

~Combine like terms

15x + 96 = 360

~Subtract 96 to both sides

15x = 264

~Divide 15 to both sides

x = 17.6

Best of Luck!

Answer: 56.2 miles

Step-by-step explanation:

5.95+0-25x less or equal 20

0.25x less or equal 20 - 5.95

0.25x less or equal 14.05

X less or equal 14.05/0.25

X = 56.2

Katie can travel at most 56.2 miles in $20.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is called inequality.

According to the given question.

The total money Katie have = $20.

Amount charged by cab taxi for ride = $5.95

Charges for per mile ride = $0.25

Let Katie travel x miles without exceeding her expending limit.

From the given condition we get a inequality

[tex]20\geq 5.95+0.25x[/tex]

Solve the above inequality for x.

⇒[tex]20 - 5.95\geq 0.25x[/tex]

⇒ [tex]14.05\geq 0.25x[/tex]

⇒[tex]x\leq \frac{14.05}{0.25}[/tex]

⇒[tex]x\leq 56.2miles[/tex]

Katie can travel at most 56.2 miles in $20.

Answer:

   4x^2 +5x -6

Step-by-step explanation:

The remaining empty space is the difference between the original amount of empty space and the volume that was filled.

  (8x^2 +2x -4) -(4x^2 -3x +2) = 8x^2 +2x -4 -4x^2 +3x -2

  = (8 -4)x^2 +(2 +3)x +(-4 -2)

  = 4x^2 +5x -6

The jar could hold 4x^2 +5x -6 more cubic inches.

Answer:

The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh

[tex]p(pressure) = s(atmospheric \: pressure) + d(density \: of \: the \: liquid)g(acceleration \: due \: to \: gravity)h[/tex]

Step-by-step explanation:

where s is the atmospheric pressure, d is the density of the liquid and g is the acceleration due to gravity.

Answer = -34

Step-by-step explanation:

B = 4 ; y = -6

So,

-4 + (5) (−6)

= −4 + −30

= −34

Hope you get it :)

The value of expression will be;

⇒ - 34

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ - b + 5y

And, The values are,

⇒ b = 4, y = - 6

Now,

Since, The expression is,

⇒ - b + 5y

Substitute  b = 4, y = - 6, we get;

⇒ - 4 + 5 × - 6

⇒ - 4 - 30

⇒ - 34

Thus, The value of expression is,
