Answer: her speed was “44 miles per hour”
Assuming Ms. Larson was travelling at a constant speed in that half hour, her speed would have been 44 miles per hour.
In order to find the speed of something, use the formula:
= Distance / Time
The distance was:
= First distance from home - Second distance from home
= 120 - 98
= 22 miles
The time was half an hour so will be presented as:
= 0.5 hours
The speed is therefore:
= 22 / 0.5
= 44 miles per hour
In conclusion, Ms. Larson is going at 44 miles per hour.

What is the answer to 4x+y=10
Answer:
y = -4x + 10
Step-by-step explanation:
I am going to assume you are trying to write the equation of a line.
4x + y = 10
4x - 4x + y = 10 - 4x
y = -4x + 10
What is the equation of the line in standard form?

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

Which statements regarding the diagram Triangle EBC are true? Select three options
•Angle BEC is an exterior angle
•Angle DEC is an exterior angle
•Angle ABE and EBC are supplementary angles
•Angle BCF and DEC are supplementary angles
•Angle BEC us a remote interior angle to exterior angle BCF
Triangle EBC have interior angles and exterior angles. The three appropriate options to the given question are:
B. Angle DEC is an exterior angle
C. Angle ABE and EBC are supplementary angles
E. Angle BEC is a remote interior angle to exterior angle BCF
An exterior angle is one that lies outside a given figure. Thus, it is not an interior angle of the figure. While an interior angle is an angle within the boundaries of the figure.
Supplementary angles are two or more angles whose measures add up to the value of angle on a straight line (i.e [tex]180^{o}[/tex]).
Thus considering the given triangle EBC, the appropriate options to the question are:
B. Angle DEC is an exterior angle
C. Angle ABE and EBC are supplementary angles
E. Angle BEC is a remote interior angle to exterior angle BCF
These three options best describes the relationships among the angles of the triangle.

What is volume of thi shown below?
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
