1) Let's begin with the table. Note that cm relates to the height
height 206 193 198 172 190
weight 91.8 85.3 84.9 78 81.5
A) The Rage of the heights is obtained by subtracting the biggest from the smallest one
Range: 206 -172 = 34
B) The mean height is obtained by this formula, the sum of those heights divided by the number of heights (5)
\(\begin{gathered} x=\frac{206+193+198+172+190}{5} \\ x=\frac{959}{5}=191.8 \end{gathered}\)C) The range of the weights, similarly to the heights shows us how spread are the weights. Subtracting the heaviest from the lightest player
Range of the weights: 91.8 -78 =13.8
D) The mean weight, similarly to B is obtained this way
\(\begin{gathered} x=\frac{91.8+85.3+84.9+78+81.5}{5} \\ x=84.3 \end{gathered}\)3) Hence, the answers are
A) 34 cm
B) 191.8 cm
C) 13.8 kg
D) 84.3 kg
A regional survey found that 60% of all families who indicated an intention to buy a new car bought a new car within 3 months, that 10% of families who did not indicate an intention to buy a new car bought one within 3 months, and that 26% indicated an intention to buy a new car. If a family chosen at random bought a car, find the probability (as a percent) that the family had not previously indicated an intention to buy a car. (Round your answer to two decimal places.)
Let A be the event that a family chose at random indicated an intention to buy a new car and let B be the event that a family chose at random bought a new car within 3 months.
We are asked to find P(A'), which is the probability that a family chosen at random had not previously indicated an intention to buy a car.
We can use the given information to write the following conditional probabilities:
P(B | A) = 60%
P(B | A') = 10%
P(A) = 26%
We can use these probabilities to apply Bayes' theorem to find P(A' | B), which is:
P(A' | B) = P(B | A') * P(A') / P(B)
Substituting the values from the problem, we have:
P(A' | B) = (10%) * (100% - 26%) / (60% * 26% + 10% * (100% - 26%))
= (10%) * (74%) / (60% * 26% + 10% * 74%)
= (10%) * (74%) / (15.4% + 7.4%)
= (10%) * (74%) / (22.8%)
= 43.86%
Therefore, the probability that a family chosen at random had not previously indicated an intention to buy a car is 43.86%.

The initial population size is 367 fish.
The population size after 8 years is 878 fish.
To find the initial population size of the species, we can substitute t = 0 into the population function:
P(0) = 2200 / (1 + 5\(e^{-0.15t\)))
Since e⁰ = 1, the equation simplifies to:
P(0) = 2200 / (1 + 5)
P(0) = 2200 / 6
P(0) ≈ 366.67
So, the initial population size is 367 fish.
To find the population size after 8 years, we substitute t = 8 into the population function:
P(8) = 2200 / (1 + 5\(e^{(-0.15 . 8)\))
P(8) = 2200 / (1 + 5\(e^{(-1.2)\))
P(8) = 2200 / (1 + 5(0.3012))
P(8) = 2200 / (1 + 1.506)
P(8) = 2200 / 2.506
P(8) ≈ 878.35
Thus, the population size after 8 years is 878 fish.

A vacant lot is being converted into a community garden. The garden and a walkway around its perimeter have an area of 648 square feet. Find the width of the walkway if the garden measures 12 feet wide by 15 feet long.
The width cannot be negative, the width of the walkway is 6 feet. The total area of the garden and the walkway is given as 648 square feet. We know the area of the garden is length multiplied by width, which in this case is 12 feet by 15 feet, so the garden area is\(12 \times 15 = 180\) square feet.
To find the area of the walkway, we subtract the garden area from the total area. Therefore, the area of the walkway is 648 - 180 = 468 square feet.
The walkway surrounds the garden on all sides, so its length and width will be greater than the corresponding dimensions of the garden.
To calculate the width of the walkway, we can use the formula for the area of a rectangle, which is length multiplied by width. In this case, the length is 12 + 2x (twice the width of the walkway) and the width is 15 + 2x.
So, we have the equation\((12 + 2x) \times (15 + 2x) = 468\).
Expanding and rearranging the equation, we get\(4x^2 + 54x - 228 = 0.\)
Solving this quadratic equation using factoring, completing the square, or the quadratic formula, we find that x = 6 or x = -9/2.

Find the arc length of the curve below on the given interval by integrating with respect to x.
y=2x^(3/2); [0, 1]
The arc length of \(y=2x^{\frac32}\) over [0, 1] is given by the integral,
\(L=\displaystyle\int_0^1\sqrt{1+\left(\frac{\mathrm dy}{\mathrm dx}\right)^2}\,\mathrm dx\)
Differentiate y with respect to x using the power rule:
\(\dfrac{\mathrm dy}{\mathrm dx}=\dfrac32\times2 x^{\frac32-1}=3x^{\frac12}\)
Then the integral becomes
\(L=\displaystyle\int_0^1\sqrt{1+\left(3x^{\frac12}\right)^2}\,\mathrm dx=\int_0^1\sqrt{1+9x}\,\mathrm dx\)
Substitute u = 1 + 9x and du = 9 dx :
\(L=\displaystyle\int_0^1\sqrt{1+9x}\,\mathrm dx=\frac19\int_1^{10}\sqrt u\,\mathrm du\)
\(L=\displaystyle\frac19\left(\frac23u^{\frac32}\right)\bigg|_1^{10}\)

A garden table and a bench cost 670 combined. The garden table costs 80 less than the bench. What is the cost of the bench?
The bench costs $375, and the garden table costs $295. Together, they amount to $670, with the table being $80 cheaper than the bench.
Let the cost of the bench be x. Then the cost of the garden table is x-80. The sum of the costs of both items is $670. So we have the equation: x + (x-80) = $670.
Simplifying this, we get 2x - 80 = $670 + 80 2x = $750 x = $375. So the cost of the bench is $375. The garden table costs $375 - $80 = $295. A garden table and a bench cost $670 combined.
The garden table costs $80 less than the bench. To find the cost of the bench, we can use algebraic equations. Let the cost of the bench be x. Then, the cost of the garden table is x - 80.
The sum of both costs is $670. Using this information, we can form an equation: x + (x - 80) = $670. Simplifying, we get 2x - 80 = $670 + 80. Solving for x, we get x = $375.
Therefore, the cost of the bench is $375, and the cost of the garden table is $295.

Step-by-step explanation:
A right triangle is a type of triangle that has one angle that measures 90°.
In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse.
\(\sin(\theta)=\frac{opposite \:site}{hypotenuse}\)
To find the value of x we use the above definition. From the diagram we can see that the angle is 30º and the hypotenuse is \(4\sqrt{2}\). Therefore,
\(\sin(30)=\frac{x}{4\sqrt{2} }\\\\\frac{x}{4\sqrt{2}}=\sin \left(30^{\circ \:}\right)\\\\\frac{8x}{4\sqrt{2}}=8\sin \left(30^{\circ \:}\right)\\\\\sqrt{2}x=4\\\\\frac{\sqrt{2}x}{\sqrt{2}}=\frac{4}{\sqrt{2}}\\\\x=2\sqrt{2}\)
To find the value of y we use the above definition. From the diagram we can see that the angle is 60º and the hypotenuse is \(4\sqrt{2}\). Therefore,
\(\sin(60)=\frac{y}{4\sqrt{2} }\\\\\frac{y}{4\sqrt{2}}=\sin \left(60^{\circ \:}\right)\\\\\frac{8y}{4\sqrt{2}}=8\sin \left(60^{\circ \:}\right)\\\\\sqrt{2}y=4\sqrt{3}\\\\\frac{\sqrt{2}y}{\sqrt{2}}=\frac{4\sqrt{3}}{\sqrt{2}}\\\\y=2\sqrt{6}\)

A shipping box is 36 inches by 24 inches by 18 inches
how many cubic feet can it hold
Answer:
To find the volume of the shipping box in cubic feet, we need to convert the dimensions from inches to feet and then calculate the volume.
Given:
Length = 36 inches
Width = 24 inches
Height = 18 inches
Converting the dimensions to feet:
Length = 36 inches / 12 inches/foot = 3 feet
Width = 24 inches / 12 inches/foot = 2 feet
Height = 18 inches / 12 inches/foot = 1.5 feet
Now, we can calculate the volume of the box by multiplying the length, width, and height:
Volume = Length * Width * Height
Volume = 3 feet * 2 feet * 1.5 feet
Volume = 9 cubic feet
Therefore, the shipping box can hold 9 cubic feet.
Step-by-step explanation:
First convert the units because it's asking for the cubic feet but they give us the measurements in inches.
To convert inches to feet we divide the number by 12.
36 ÷ 12 = 3
24 ÷ 12 = 2
18 ÷ 12 = 1.5
Now to find the volume, we multiply it all together.
3 × 2 × 1.5 = 9
It can hold 9 cubic feet.

What is Sine rule of triangle?
By the definition of sine rule,
sin A / a = sin B / b = sin C / c
Where, a, b, c are sides of a triangle.
Given that;
Measure of ∠A = 27°
Measure of ∠B = 76°
Since, Sum of all angles of triangle = 180°
Hence,
∠A + ∠B + ∠C = 180°
27° + 76° + ∠C = 180°
∠C = 180° - 103°
∠C = 77°
So, Measure of ∠C = 77°
Since, By the definition of sine rule,
sin A / a = sin B / b = sin C / c
Since, sin A = sin 27° = 0.95
sin B = sin 76° = 0.566
sin C = sin 77° = 0.99
Hence,
0.95 / a = 0.566 / b = 0.99 / c = 1 / k
Taking terms as;
0.95 / a = 1 / k
a = 0.95 k
And, 0.566 / b = 1 / k
b = 0.566 k
And, 0.99 / c = 1 / k
c = 0.99 k
Hence, Sides of triangles are;
a : b : c = 0.95 k : 0.566 k : 0.99 k
a : b : c = 0.95 : 0.566 : 0.99
Thus, Measure of ∠C = 77°

the angle below the angle of 50° is congruent to it, then, the angle is 50°.
To determine the measure of angle 2, consider that the sum of the interior angles of a triangle is equal to 180°:
50 + 90 + m∠2 = 180°
m∠2 = 180° - 50° - 90°
m∠2 = 40°
Angle 3 is also a right angle, then:

What is meant by triangle?Three edges and three vertices define a triangle as a polygon. One of geometry's fundamental shapes is this one.
Any three points determine a distinct triangle and a distinct plane in Euclidean geometry when they are non-collinear (i.e. a two-dimensional Euclidean space). To put it another way, each triangle is contained in a plane, and there is only one plane that includes that particular triangle. All triangles are contained in one plane if and only if all geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except as otherwise specified, the subject of this article is triangles in Euclidean geometry, more specifically, the Euclidean plane.
Given,
C=61° 50, c=31.2, b=23.6
Sine rule:
sin B/b=Sin C/c
sin B=b sin C/c
=(23.6 sin 61° 50)/31.2
sin B=0.65219
sin B=139.3
A+B+C=180
A=180-B-C
A=180-139.3-61.50
A= -20.8 which is not possible.
Because the angle must be positive.
