Answer:
The diameter must pass through the center of the circle.
Step-by-step explanation:
TRUE STATEMENT :
The diameter must pass through the center of the circle.
Answer:
A. Both chords and diameters have two endpoints on a circle. Diameters must intersect the center of a circle.
Step-by-step explanation:
The only way to answer this question is to check the definitions of chord and diameter.
A chord is a segment with endpoints on the circle. In the attached figure the segments CD and GH are chords.
Now, notice that according to the given definition the segment EF is also a chord, but with the special characteristic that the center of the circle, denoted by A, it is on the segment. This ‘‘special’’ chords that contains the center of the circle are called diameter.
Sometimes the diameters are also called the larger of the chords.

0
100 150 200 250 300 350
Height (cm)
5 trees
30 trees
50 trees
10 trees
The number of trees are between 150 cm and 200 cm tall is 30 trees.
It is required to find the number of trees are between 150 cm and 200 cm tall.
What is histogram?A histogram is a graph that shows the frequency of numerical data using rectangles. It is used to summarize discrete or continuous data that are measured on an interval scale.
Given:
The histogram graph the number of trees are arranged in vertical direction or y -axis and height of trees are arranged in horizontal direction or x -axis.
According to given question we have,
The number of trees are between 150 cm and 200 cm tall
=30
Therefore, the number of trees are between 150 cm and 200 cm tall is 30 trees.

Please explain your steps when solving the equation:
-3b + 6 = 18
Answer:
b=-4
Step-by-step explanation:
-3b+6=18
-3b=12 (subtracted 6 from both sides)
b=-4 (divided both sides by -3)
Geometry - Law of Sines question #17. Please help, I am stuck.
By the law of sines, m∠EFG is such that
sin(m∠EFG) / (8 in.) = sin(m∠G) / (7.5 in)
so you need to find m∠G.
The interior angles to any triangle sum to 180°, so
m∠DEG = m∠D + m∠G + 43°
m∠DEG + m∠D + m∠G = 2 (m∠D + m∠G) + 43°
180° = 2 (m∠D + m∠G) + 43°
137° = 2 (m∠D + m∠G)
68.5° = m∠D + m∠G
But ∆DEG is isosceles, so m∠D = m∠G, which means
68.5° = 2 m∠G
34.25° = m∠G
Then
sin(m∠EFG) = (8 in.) sin(34.25°) / (7.5 in)
m∠EFG ≈ sin⁻¹(0.600325) ≈ 36.8932°
The speed of sound (shockwave) in an explosion is 100mph. How many seconds does the shockwave reach 2km away?
Answer:
t = 44.73 s
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 100 mph = 44.704 m/s
We need to find the time taken by the shockwave to reach 2 km i.e. 2000 m
We know that,
Speed = distance/time
So,
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{2000}{44.704}\\\\t=44.73\ s[/tex]
So, it will take 44.73 seconds to reach 2 km.

The area of a right triangle is 3gh. Find the height if the base is 3gh.
Area of a triangle: A = 1/2bh
Answer: height is 2
Step-by-step explanation:
A = 1/2bh
A = 3; b (base) = 3. Substitute these values in the formula and solve.
3 = 1/2*3*h = 3/2 h
h = 3 * (2/3) = 2
Answer:
Height = 2
Step-by-Step Explanation:
So, I'm not sure if "gh" is a measurement. But I'm thinking it should be solved like this.
Area = 3gh
Base = 3gh
Height = ?
Plug & Chug
3gh = 1/2 (3gh)(h)
2/1 · 3gh = 1/2 (3gh)(h) · 2/1
[tex]\frac{(2)(3gh)}{(3gh)\\}[/tex] = [tex]\frac{(3gh)(h)}{(3gh)}[/tex]
h = [tex]\frac{(2)(3gh)}{(3gh)}[/tex]
h = 2

2x + 3y = 11 and 2y = 13 – 3x
Answer:
x = 3.4
y = 1.4
Step-by-step explanation:
2x + 3y = 11
2y = 13 – 3x, then y = (13 - 3x)/2
substitute for y:
2x + 3((13 - 3x)/2) = 11
reduce:
2x + (39 - 9x)/2 = 11
reduce:
2x + 19.5 - 4.5x = 11
subtract 19.5 from both sides of the equation and combine for x:
-2.5x = -8.5
divide both sides by -2.5:
x = 3.4
y = (13 - 3(3.4))/2 = (13 - 10.2)2 = 1.4

Thomas has 12 more marbles than twice the number of marbles Andrew has. Andrew has x marbles. Which expression represents how many marbles Thomas has?
Answer:
2x + 12
Step-by-step explanation:
Let
x = number of marbles Andrew has
Number of marbles Thomas has = 2x + 12
The expression which represents number of marbles Thomas has = 2x + 12
If Andrew has 2 marbles, that is, x = 2
Then, 2x + 12 = 2(2) + 12
= 4 + 12 = 16
Thomas = 16 marbles
En una muestra de 50 restaurantes de comida rápida, la venta media fue de $3.000, y la desviación estándar, $200. El intervalo de confianza del 95% es
Respuesta:
(2945.411; 3054.589)
Explicación paso a paso:
Dado ;
Tamaño de la muestra, n = 50
Media, xbar = 3000
Desviación estándar, s = 200
Nivel de confianza, Zcrítico al 95% = 1,96
El intervalo de confianza se define como:
Xbar ± margen de error
Margen de error = Zcrítico * s / sqrt (n)
Margen de error = 1,96 * 200 / sqrt (50)
Margen de error = 54.589
Límite inferior = (3000 - 54.589) = 2945.411
Límite superior = (3000 + 54.589) = 3054.589
(2945.411; 3054.589)

A rectangle has an area of 1,280.64 square miles and a base of 36.8 miles. What is the height?
Answer:
34.8 miles
Step-by-step explanation:
First, we know that Area = Length * Width. Let's plug in those values.
1,280.64 = x * 36.8 (I put the variable "x" there since we don't know what it is)
Now, solve for x (we want to have x by itself, so divide both sides by 36.8)
34.8 = x
Now that we know that the width of it is 34.8 miles, let's check our work.
34.8 * 36.8 = 1,260.64
This equation IS true, so:
The width of the rectangle is 34.8 miles. Hope this helps!
