What geometric shapes can you draw that have exactly four pairs of perpendicular​ sides? Use pencil and paper. Sketch examples for as many different types of shapes as you can. PLEASE HELP

Answers

Answer 1

There are several geometric shapes that have exactly four pairs of perpendicular sides. Some examples include rectangles, squares, rhombuses, and parallelograms.

1. Rectangle: A rectangle is a quadrilateral with four right angles, making all four sides perpendicular to each other.

2. Square: A square is a special type of rectangle with all sides of equal length. Since all angles in a square are right angles, all four sides are perpendicular.

3. Rhombus: A rhombus is a quadrilateral with all sides of equal length. Its opposite sides are parallel and all four angles are right angles, making it have four pairs of perpendicular sides.

4. Parallelogram: A parallelogram is a quadrilateral with opposite sides parallel. If it has adjacent sides that are perpendicular, then it will have four pairs of perpendicular sides.

These are just a few examples of geometric shapes with four pairs of perpendicular sides. There are other shapes as well, such as certain trapezoids and kites, that can also have this property depending on their specific attributes.

How many pairwise comparisons must you make for a case with 15 statistically independent scenarios?

Answers

There are 105 comparisons made with 15 statistically independent scenarios.

According to the statement

we have given value of n is 15.

Then r = 2. so,

we use the formula NcR then

Substitute the values in it then

15c2

we open it according to ncr formula

In this formula we arrange the terms according to the following

NcR formula = n! /r! * (n-r)!

then the terms will arrange in this way.

So,

ncr = 15! / 2! * 13!

After solving the statement some terms will be cancel with each other and remaining terms are

ncr = 15*14/2

ncr = 210/2

ncr = 105

here the value becomes 105.

Using proportions, it is found that the coordinates of point B are given as follows:

A. (1.6, 0).

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Point B is 3/4 of the way from AB to AC, hence:

[tex]B - A = \frac{3}{4}(C - A)[/tex]

The points are:

A(-2,-3).B(x,y).C(3,1).


Then, to find the x-coordinate:

[tex]x + 2 = \frac{3}{4}(3 + 2)[/tex]

x + 2 = 3.6.

x = 1.6.

For the y-coordinate:

[tex]y + 3 = \frac{3}{4}(1 + 3)[/tex]

y + 3 = 3

y = 0.

Data that expresses a definite quantity, amount, or range is known as quantitative data. In most cases, the data is accompanied with measuring units, such as metres in the case of a person's height. Setting boundaries for such data makes sense, and performing mathematical operations on the data has significance.

Types of Quantitative Data are-

In a bag there are 3 red 4 white, and 5 blue marbles. once a marble is selected it is not required. find: p(white, red) find: p(blue, white, red.)

Answers

Answer:

Below in bold.

Step-by-step explanation:

Total number of marbles = 3+4+5 = 12

P(white, red) = 4/12 * 3/11

                      = 12/132

                      = 1/11,

P(blue, white, red)  = 5/12 * 4/11* 3/10

                                 = 60/1320

                                 = 6/132

The number of compounding per year is[tex]N = 920(1+0.03)^4t[/tex]

How can the number of compounding per year be calculated?

This can be calculated by making use of the formular;  920(1.03)^4t and use the  compound interest equation which is N=P( 1+r/n)^nt

We know that 12% was given as the rate per year, then to get the quarter rate we divide by factor of 4, which is  12/4= 3%

The compounding for t years = n*t = 4t where n=4.

a. Write the equation that relates the cost, c, with the number of miles, m.
b. What would it cost to travel 22 miles with this service?

Answers

The time it will take for the block of ice to melt if the temperature is 45 degrees is 3 hours.

The cost to travel 22 miles is 55 dollars.

How to find how long for the ice to melt?

let

time it takes for ice to melt = x

air temperature = y

Therefore,

x ∝ 1 / y

x  = k / y

when x = 2.5 hours and y = 54 degrees

Hence,

k = 2.5 × 54

k = 135

The time it will take for the block to melt at 45 degrees = 135 / 45 = 3 hours

How to find equation that relates the cost to the number of miles?

It costs $35 for a ride from the city centre to the airport, 14 miles away.

where

c = cost

m = number of miles

Therefore, the equation is as follows:

35 / 14 = 2.5

c = 2.5m

Hence, when you travel 22 miles,

c = 22(2.5)

c = 55 dollars

Answers

The amount of money Kim, maneet and Sutopa have is $115.6, $97.6 and $73.2 respectively.

Equation

Kim = xManeet = x - 18Sutopa = 3/4(x-18)Total = $286.40

x + (x - 18) + 3/4(x-18) = 286.40

x + x - 18 + 3/4x - 13.5 = 286.40

2 3/4x = 286.40 + 13.5 + 18

11/4x = 317.9

x = 317.9 ÷ 11/4

= 317.9 × 4 / 11

= 1,271.6 / 11

x = $115.6

So,

Kim = x

Maneet = x - 18

Find equation of the line passing through the point (-1,0) and parallel to the line y=-1/2x + 3/7

Answers

Answer:

Step-by-step explanation:

A parallel line will have the same slope, m, as the reference line given by the form y=mx+b.  b is the y-intercept, the value of y when x=0.

The reference line of y = -(1/2)x + (3/7) has a slope of -(1/2).

The parallel line will have the same slope, so we can write:

y - -(1/2)x + b

We need a value of b that forces the line to go through point (-1,0).  Enter that point in the equation and solve for b:

y - -(1/2)x + b

0 - -(1/2)(-1) + b

b = -(1/2)

The equation of the line parallel to y = -(1/2)x + (3/7) and going through (-1,0) is

  y=-(1/2)x - (1/2)

The vertices of a quadrilateral are A(-1,6),B(-2,4),C(2,2), and D(3,4). Write a paragraph proof to determine whether quadrilateral ABCD is a rectangle. 15px

Determining the slopes of each side, we get the slope of [tex]\overline{AB}[/tex] is [tex]2[/tex], the slope of [tex]\overline{BC}[/tex] is -1/2, the slope of [tex]\overline{CD}[/tex] is 2, and the slope of [tex]\overline{AD}[/tex] is -1/2. Since the slopes of sides AB and CD and BC and AD are equal, it follows that [tex]\overline{AB} \parallel \overline{CD}[/tex] and [tex]\overline{BC} \parallel \overline{AD}[/tex]. Thus, ABCD is a parallelogram because it is a quadrilateral with two pairs of opposite congruent sides. However, we can also note that the slope of side AB is the negative reciprocal of that of sides BC, and thus [tex]\overline{AB} \perp \overline{BC}[/tex]. Using the fact that perpendicular lines form right angles, we can conclude that [tex]\angle ABC[/tex] is a right angle, and since ABCD is thus a parallelogram with a right angle, it must also be a rectangle.

Answer:

Answers will vary based on the method used, but the final slope-intercept form of the equation of A⁢B↔ will be the same.Let the equation of A⁢B↔ in slope-intercept form be y=m⁢x+d, where m is the slope and d is the y-intercept.The coordinates of points A and B are (1, 1) and (5, 3), respectively, so the slope of A⁢B↔ is m=yB−yAxB−xA=24=0.5.Substitute the value of m back in the equation:y = 0.5x + d.Substitute the coordinate of point A (1, 1) in the equation above, and solve for d: 1 = 0.5 + dd = 0.5.Therefore, the equation of A⁢B↔ is y = 0.5x + 0.5. To check whether C lies on A⁢B↔ substitute the x-coordinate of C into the right side of the equation: 0.5 (2.6) + 0.5 = 1.8.The result is equal to the y-coordinate of C. Thus, C satisfies the equation of A⁢B↔ which means that C lies on A⁢B↔.
