The tools that Greeks limit themselves to in their formal geometric constructions are straight edge and compass. Therefore, A and B are the correct answers.
What are geometric constructions?Geometric construction is the process of drawing a geometrical figure using two geometrical instruments, a compass, and a ruler.
Compass and straight edge were the tools that were used by Greeks in their formal geometric construction.
During earlier Greek times, simple geometric tools were used like compass and straight edge to draw something. Rulers and other tools came to use much later in time.
Therefore, A and B are the correct answers.

A school psychologist at a large high school took a random sample of 16 students and asked how much sleep they get on a typical weekend night. The sample data were roughly symmetric with a mean of 8.75 hours and a standard deviation of 1.5 hours
Answer:
8.75 +/- 0.657
Step-by-step explanation:
The 90% confidence interval for the mean amount of sleep this population of students gets on a typical weekend night is 8.75±0.617
What is confidence interval?A confidence interval is a range around a measurement that conveys how precise the measurement is.
Given that, The sample data were roughly symmetric with a mean of 8.75 hours and a standard deviation of 1.5 hours, the confidence level value is 90%
confidence interval = x ± z·s/√n
= 8.75±1.645·1.5/√16
= 8.75±0.617
Hence, the 90% confidence interval for the mean amount of sleep this population of students gets on a typical weekend night is 8.75±0.617

the equation for the cross section of a parabolic satellite television dish is y=1/50x^2 measured in inches, how far is the focus from the vertex of the cross section?
Answer:
12.5 inches
Step-by-step explanation:
Given the equation for the cross section of a parabolic satellite TV dish:
y=1/50x^2
Equation of a parabola :
(y - k) = 1/4p * (x - h)^2
Distance of the focus from the Vertex = p
Comparing both equations :
1/4p * (x - h)^2 = 1/50 * x^2
4p = 50
Divide both sides by 4
4p/4 = 50/4
p = 12.5 inches

Answer:

Step-by-step explanation:
Height of the conical top= 25 cm
Diameter of the conical top = 20 cm
Radius of the conical top = 10 cm
[tex]We\ know\ that,\\Volume\ of\ a\ cone\ = \frac{1}{3}\pi r^2h\\Hence,\\Volume\ of\ the\ conical\ top\ = \frac{1}{3}\pi 10^2*25 = \frac{1}{3} \pi 100*25\\= 833.3\pi\ cm^3[/tex]
Height of the cylindrical base = 35 cm
Diameter of the cylindrical base = 20 cm
Radius of the cylindrical base = 10 cm
[tex]We\ know\ that\ ,\\Volume\ of\ a\ cylinder\ = \pi r^2h\\Hence,\\Volume\ of\ the\ cylindrical\ base = \pi* 10*10*35\\=3500\pi\ cm^3[/tex]
[tex]Hence,\\Volume\ of\ the\ given\ figure\ = Volume\ of\ the\ conical\ top\ + Volume\ of\ the\ cylindrical\ base\ \\Hence,\\Volume\ of\ the\ given\ figure\ =833.3\pi +3500\pi \\=(3500+833.3)\pi \\=4333.3\pi \\=13613.46 cm^3[/tex]
Answer:
13,614cm³
Explanation:
There are 2 solid shapes in the object;
A cylinder and A cone
Volume of the cylinder = πr²h
Volume of the cone is 1/3πr³h
h of cone = 25cm
h of cylinder = 35cm
d of the cylinder and cone = 20cm
r = d/2 = 10cm
Volume of the cylinder = πr²h
= π(10)²×35 = 10,996cm³
Volume of the cone = 1/3πr²h
= 1/3π(10)²×25 = 2618cm³
Therefore the total volume of the object above =
Volume of the cylinder + Volume of the cone =
10,996cm³ + 2618cm³ = 13,614cm³

Write out the equation in Mx+b
Answer
y= 3/2 x - 2
Step-by-step explanation:
so you have to find the slope which would be
m =
y2 - y1
x2 - x1
then you find you points that you are using (2, 1) and (0, -2)
when you plug it in it is
m=
-2-1
0-2
you simplify the numbers and get rid of the negatives to get m=3/2 x
then your y intercept is where your line meets the y axis or wherever x=0
so your y intercept is (0, -2) so the b = -2
