Step-by-step explanation:

mean = sum of all data points / number of data points

(1.3+1.5+2.2+2.2+2.8)/5 = 10/5 = 2

median is the number where half of the other data points are smaller or equal, and the other half are larger or equal.

median = 2.2

mode is the data point occurring most often = 2.2

range is the difference between largest and smallest data point : 2.8 - 1.3 = 1.5

to "show work" just plug in each x value into that equation. you will never learn if all you do is copy down answers. i have given you all of the correct answers, and all you need to do is plug in the values for each x value into the equation, multiply then add. good luck man.

Answer:

113.04 ft^2

Step-by-step explanation:

area of circle formula = [tex]\pi r^{2}[/tex]

in this case, we are taking π as 3.14, so it is 3.14 x [tex]r^{2}[/tex]

Radius = half of diameter

radius = 12 / 2 = 6

[tex]6^{2}[/tex] = 36 (because 6 x 6 = 36)

3.14 x 36 = 113.04

Therefore, our answer is 113.04 ft squared (because it is area)

Answer:

38.5

Step-by-step explanation:

to find the area of the triangle, you can do 11 x 3 ÷ 2 = 16.5

then you find the area of the triangles: 3 x 3 = 9

and 3 × 11 = 33

then you add them all to find a total area of 38.5

Answer: 18x + 12

Step-by-step explanation:

Step #1: Determine the length of each side.

The polygon is regular, so all the sides are equal. Thus, all sides measure 3x+2.

Step #2: Determine the number of sides in the polygon.

This polygon is identified as a hexagon meaning it consists of 6 sides.

Step #3: Set up an expression and distribute.

       (Number of sides) x (Length of each side)

       (6)(3x+2)

So, the answer is 18x + 12.

Answer:

B. 3x + 2

Step-by-step explanation:

The polygon has 6 equal sides.

1 side has a side length of 3x + 2

Therefore, all sides of the polygon measure 3x + 2

Hope this helps!

Answer:

Step-by-step explanation:

y = 4x + 1

2y - 2 = 8x

Answer:

  B.  53 square inches

Step-by-step explanation:

The attached figure is drawn to scale, and a grid is provided that makes it easier to see the dimensions of the various parts.

This figure can be easily decomposed into an overall rectangle with cutouts of a trapezoid at the top and a rectangle at the bottom right.

__

The overall rectangle has dimensions 8 units wide and 10 units high.

The trapezoid at the top has bases of 8 units and 7 units, and a height of 2 units.

The rectangle at the bottom right has dimensions of 4 units wide and 3 units high.

The area formulas for a rectangle and trapezoid are ...

  A = LW . . . . area of a rectangle with length L, width W

  A = 1/2(b1 +b2)h . . . . area of a trapezoid with bases b1, b2, and height h

__

Then the area of the figure is ...

  figure area = overall rectangle - trapezoid - lower right rectangle

  = (8 in)(10 in) - 1/2(7 in + 8 in)(2 in) -(4 in)(3 in)

  = 80 in² -15 in² -12 in² = 53 in²

The area of the object is 53 square inches.

The expression of  the factored form of 2x2+25x + 63 is mathematically given as

(x+7)(2x+7)

Question Parameter(s):

Expression 2x^2+25x + 63?

The expression of the factored form will bear the roots of the expression repressented  in standard form

2x^2+25x + 63?

Therefore

2x^2+25x + 63?

x(2x+7)+9(2x+7)

(x+7)(2x+7)

In conclusion, The expression is

(x+7)(2x+7)

CP=SP*100÷100+P

so,

CP=10350*100÷100+15

CP=9000

Answer:

solution

Step-by-step explanation:

Let.the cp of TV be RS X

now,CP=SP-profit

or, CP=SP-profit% of Cp (as profit amount =profit % of Cp)

or, x=Rs 10350-15÷100× X

or, x= Rs 10350 _ 3X ÷20

or, x+3x ÷20 =Rs 10350

or, 23x ÷20 = Rs 10350

or, x = 10350×20 divided by 23

Therefore X =Rs 9000

The additive inverse of –2+ 8i will be 2 – 8i. The additive inverse of a digit is the digit that delivers zero when added to it.

The additive inverse of a number is the number that produces zero when added to it. A negative number's additive inverse is positive. The additive inverse of itself is zero.

From the definition;

[tex]\rm x= 2+ 8i \\\\ \rm x= 2+ 8i + 2-8i \\\\ \rm x= 0[/tex]

Option C gives zero on addition. That's why it is correct.

Hence the additive inverse of –2+ 8i will be 2 – 8i.

Answer:

Each box of two inch nails contained 67 nails

Step-by-step explanation:

Givens

291 one inch nails

5 boxes of 2 inch nails

Total number of nails = 626 nails

Formula

291 + 5*two = 626      Two is the number of 2" nails in one box

Solution

291 + 5*two = 626              Subtract 291 from both sides.

5*two = 626 -291                Combine

5*two = 335                        Divide both sides by 5

5*two/5 = 335/5

two = 67

Step-by-step explanation:

yes, it is a function.

the reason : every value of x (2, 4, -2, 0) has exactly one assigned value of y : 2 to 3, 4 to 5, -2 to -1, 0 to 1.
