Answer:

Your median is 4.1.

Step-by-step explanation:

What is the median

The median is a measure of central tendency. It represents the value for which 50% of observations a lower and 50% are higher. Put simply, it is the value at the center of the sorted observations.

Median formulas

This calculator uses two different formulas for calculating the median, depending on whether the number of observations is odd, or it is even when the number of observations is odd the formula.

Answer:

Your answer is B.), 26 in.²

Step-by-step explanation:

So, what you do is you have to split it into two different shapes, find the areas of those, and then "put them back together" (add them together).

So, what I did is I made the whole top part one shape and then the bottom part. Here are the dimensions:

Top Part: 2 in. × 9 in.

Bottom Part: 4 in. × 2 in.

Now, you multiply and add them.

Top Part:

[tex]2*9=18[/tex]

Bottom Part:

[tex]4*2=8[/tex]

Add:

[tex]18+8=26in.^{2}[/tex]

Since it's a 2-dimensional figure, do not forget that when you label, you have to put a "2," as in "squared," like it's an exponent, but know that it is not an exponent. It's just so that people know, when looking at it, that it's the area of a 2-dimensional figure.

Answer:

19.11 square units

Step-by-step explanation:

The fish tank is composed by eight rectangles with base = 0.9 units and height = 2 units; and by a regular octagon at the bottom, which sides are 0.9 units long.

Area of each rectangle = 0.9*2 = 1.9 square units

Area of the regular octagon = 2*(1 + √2)*0.9² = 3.91 square units

Therefore:

Surface area of the fish tank = 8*1.9 + 3.91 = 19.11 square units

Answer:

Step-by-step explanation:

Area of a triangle = 1/2 * Base * Height

For the given triangle, the value for the sides will be the distance between adjacent points on the triangle. Look at the attached file for the explanation of the diagram.

Using the formula for finding the distance between two points to get the base and the height of the triangle.

D = √(x2-x1)²+(y2-y1)²

For side AB where A = (-3, -4) and B(2, 0)

AB = √(2-(-3))²+(0-(-4))²

AB = √5²+4²

AB = √25+16

AB = √41

AB = Height

For side BC where B = (2, 0) and C = (6, -5)

√(x2-x1)²+(y2-y1)²

BC = √6-2)²+(-5-0)²

BC= √4²+(-5)²

BC = √16+25

BC= √41

BC = base of the triangle

Area of the triangle = 1/2 * √41 * √41

Area of the triangle = 1/2 * 41

Area of the triangle =20.5square units

Answer:

Step-by-step explanation:

The diameter of the circle is the distance from the endpoint to another endpoint. The diameter of the given circle is segment PQ. To determine the diameter of the circle, we would apply the formula for determining the distance between two points on a straight line is expressed as

Distance = √(x2 - x1)² + (y2 - y1)²

Therefore,

Diameter = √(1 - - 3)² + (9 - 5)²

Diameter = √4² + 4² = √32

Radius = diameter/2 = √32/2

A circle is the set of all points in a plane equidistant from a fixed point called the origin or center.

The center of the circle is determined by applying the midpoint formula

(x1 + x2)/2, (y1 + y2)/2

= (- 3 + 1)/2, (5 + 9)/2

Center = (- 1, 7)

The formula for determining the equation of a circle us expressed as

(x - h)² + (y - k)² = r²

Where

r represents the radius of the circle

h and k represents the x and y coordinates of the center of the circle. Comparing with the given points,

h = - 1 and k = 7

Substituting into the formula, it becomes

(x - h)² + (y - k)² = r²

(x - - 1)² + (y - 7)² = (√32/2)²

(x + 1)² + (y - 7)² = 32/4

(x + 1)² + (y - 7)² = 8

Answer:

80⁰

Step-by-step explanation:

x = sum of alternate angles

x = 50 + 30

x = 80⁰

Answer:

1) 25

2) 20

Step-by-step explanation:

1)

Since these are vertical angles, they are congruent. Therefore, 3x=75, and x=25 degrees.

2)

Once again, these are vertical angles.

2+3x=62

3x=60

x=20 degrees

Answer:

The first 4 guests can arrive at party in 1365 ways if 15 guest have been invited

Step-by-step explanation:

Total number of guests invited = 15

We are supposed to find in how many ways can the first 4 guest arrive at a party if 15 guest have been invited

We will use combination

Formula :[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]

Substitute n = 15 and r = 4

So,Total no. of ways = [tex]\frac{15!}{4!(15-4)!}=1365[/tex]

Hence the first 4 guests can arrive at party in 1365 ways if 15 guest have been invited

Answer:

Step-by-step explanation:

The first 4 guests can arrive in 32,760 ways.

Answer:

Step-by-step explanation:

As you can see, the cube and the cylinder are the same height and width. But, if you use their 2d counterparts, a square and a circle, a circle always takes up 78.5% of the squares area. Knowing this, we can take this knowledge and see that the cube will have a greater volume.

Answer:

8 units

Step-by-step explanation:

Hello!

So, there's a formula we can apply to right-angled triangles: Pythagorean's theorem. It states that  c = [tex]\sqrt{{a}^2 + b^{2} }[/tex], where c is the hypotenuse and a and b are the legs of the triangle.

So, from the problem,  if c = 17 and a = 15, then, we're solving for b. So we'll rewrite the theorem to solve for b.

[tex]{c}^2 = {a}^2+{b}^2\\{c}^2-{a}^2={b}^2\\{b} = \sqrt{{c}^2-{a}^2}[/tex]

Okay, so now we have isolated the theorem for b. Let's plug in our values for c and a.

[tex]b = \sqrt{{17}^2-{15}^2}\\b = \sqrt{289-225}\\b = \sqrt{64}\\b = 8[/tex]

So, using the theorem, we found b = 8. To check our work, let's plug in b and a and solve for c.

[tex]c = \sqrt{{a}^2+{b}^2}}\\c = \sqrt{{15}^2+{8}^2}\\c = \sqrt{225+64}\\c = \sqrt{289}\\c = 17\\[/tex]

So, we got our hypotenuse to equal 17 units, which is correct! So, our b is correct too. Awesome

Answer:

the slopes of DE and EF are opposite reciprocals make the triangle Δ DEF a right triangle.

Step-by-step explanation:

The characteristics will prove that Δ DEF is a right isosceles triangle is the lengths of DE and EF are congruent, and their slopes are opposite reciprocals.

Now, the equal sides of DE = EF make the triangle Δ DEF an isosceles triangle and the slopes of two perpendicular lines are always the opposite reciprocals.

So the correct answer would be: The lengths of DE and EF are congruent, and their slopes are opposite reciprocals.

A right-angle triangle with two equal sides forming that right angle must be a right isosceles triangle.

What is a right isosceles triangle?

A triangle that has  a right-angle and two equal sides is called a right-isosceles triangle.

Characteristics will prove that ΔDEF is a right isosceles triangle are as follows:

1. A right isosceles triangle must have a right angle.

2. Two sides of it must be equal. Obviously, the hypotenuse is the biggest side of the triangle. Apart from the hypotenuse, other two sides must be same. It will make their slope with the hypotenuse equal. Hence, the triangle will be also be isosceles.

Step-by-step explanation:

Given: area of a rectangle is [tex]2x^2-7x-15[/tex]

To find: binomials that represent the length and the width of the rectangle

Solution:

A polynomial that consists of two terms is known as binomial.

[tex]2x^2-7x-15=2x^2-10x+3x-15\\=2x(x-5)+3(x-5)\\=(2x+3)(x-5)[/tex]

Also, area of rectangle is length × breadth

So, length × breadth = [tex](2x+3)(x-5)[/tex]

So, length = 2x+3, breadth = x-5 or length = x-5, breadth = 2x+3

Answer: According to me, it is :

A height of 2 feet above the ground and angle of elevation of 86 degrees. 

Assuming that the form of our problem is a right triangle, we can solve for the remaining angle:

180 - (90+86) = 4 degrees

The distance from the home plate to the centerfield is

2/sin 4 = x / sin 86

solve for x

x = 28.60 feet....

The height of the center field fence require that a ball hit 2 ft is equal to 28.60 feets

The sine is the ratio between the opposite side and the hypotenuse of a right triangle, that is, it is a trigonometric ratio. It is worth remembering that ratio or trigonometric relation is the study of the angles of a right triangle.

It is the ratio of the opposite side to the hypotenuse, that is:

[tex]Sen \theta = opposite \ side/hypotenuse[/tex]

Assuming that the form of our problem is a right triangle, we can solve for the remaining angle:

[tex]180 - (90+86) = 4 degrees\\2/sin (4) = x / sin (86)\\x = 28.60 feet[/tex]

Answer:

25. x = 17°

26. x = 50°

Step-by-step explanation:

25. There is a straight line which means :

108 +4x = 180

solving the obtained equation

108+4x = 180

4x = 180 - 108

4x = 72

x = 72/4

x = 17°

26. Again we can see that the angles in which 101 and x + 29 exists is a straight line . which means :

101 + x + 29 = 180

101 + 29 + x = 180

130 + x = 180

x = 180 - 130

x = 50°

So the answer of question no. 25 is 18 degree.

The answer of question no 26 is 50 degree.
