The radius goes from a point on a circle to the center of the circle; it is half of the diameter.
An obtuse angle is an angle that measures more than 90 degrees.
A regular polygon is a polygon that is equiangular and equilateral.
Answer 2

A diameter is a line segment that has endpoints on a circle and passes through the center of the circle. The correct option is: diameter

A diameter is a line segment that has endpoints on a circle and passes through the center of the circle. It is a crucial geometric element in the study of circles and plays a fundamental role in various geometric properties.

Key points about the diameter:

Definition: As mentioned, a diameter is a line segment that connects any two points on the circle's circumference and passes through the center of the circle. It is the longest chord of the circle.

Length: The length of the diameter is exactly twice the length of the radius. If "r" represents the radius, then the length of the diameter is "2r."

Properties: The diameter divides the circle into two equal halves, each known as a semicircle. It is also the largest possible chord of a circle.

In summary, a diameter is a significant geometric concept related to circles, and it is characterized by its property of passing through the center of the circle and being twice the length of the radius.

The correct option is: diameter

The height of the pyramid in the diagram is three times the radius of the cone. The base area of the pyramid is the same as the base area of the cone. What is the expression for the volume of the pyramid in terms of the radius r of the cone?

Answers

Since the height of the pyramid is 3 times the radius of the cone we can express height of the pyramid as a function of radius of the cone.

Let radius of cone = r
Then, height of the pyramid = 3r

Area of the base of the cone = pi x r^2 = area of the pyramid.

If the base dimensions of the pyramid are l and b, then area of the pyramid, l x b = pi x r^2.

The volume of the pyramid = 1/3 x l x b x h

We know, l x b = pi x r^2 and h = 3r.

Thus, volume of pyramid is = 1/3 x pi x r^2 x 3 r = pi x r^3

The volume of the pyramid is πr³ cubic units. Then the correct option is A.

What is the volume of the pyramid?

Suppose the base of the pyramid has length = L units, width = W units, slant height = K units, and the height of the pyramid is of H units.

Then the volume of the pyramid will be

V = (A × H) / 3

V = (L × B × H) / 3

Where, A is the base area of the pyramid.

Let r be the radius of base circle of the cone.

The height of the pyramid in the diagram is three times the radius of the cone.

Then the height of the pyramid will be 3r.

The base area of the pyramid is the same as the base area of the cone.

Base area of pyramid = Base area of cone

Base area of pyramid = πr²

Then the volume of the pyramid will be

Volume of pyramid = (1/3) x  πr² x (3r)

Volume of pyramid = πr² x r

Volume of pyramid = πr³ cubic units

The volume of the pyramid is πr³ cubic units.

Then the correct option is A.

Which number line shows the solution to
11x + 14 < –8?


Answers

Answer:

D!!

Step-by-step explanation:

Hope it helps!!

Final answer:

The solution to the inequality 11x + 14 < -8 is x < -2. On a number line, this would be a circle at -2 with a line extending to the left.

Explanation:

To find the solution to the inequality 11x + 14 < –8, we will first subtract 14 from both sides, which gives us:

11x < -8 - 14

This simplifies to 11x < -22.

Next, we divide both sides by 11 for: x < -2

The solution is x < -2. On a number line, this would be represented by a circle around -2 (not filled in, because the inequality does not include 'equal to') with a line extending to the left (indicating 'less than').

From a top-down 2D perspective, a car moves in a diagonal line and travels a distance equivalent to 80 miles. If the angle between the diagonal line and a horizontal reference line is 25 degrees, how far did the car travel horizontally and vertically? If necessary, round your answers to the nearest tenth of a mile. Horizontal distance? Vertical distance?

Answers

We can use Pythagorean theorem  for right angle triangle to solve this problem.

The diagonal line would be hypothenuze. Horizontal and vertical distance would be other two sides of a triangle.

We will use the following formulas:
[tex]sin \alpha = \frac{opposite}{hypothenuze} \\ cos \alpha = \frac{adjacent}{hypothenuze} [/tex]
Where opposite side is vertical distance and adjacent side is horizontal distance.

Solving for these two sides we have:
[tex]opposite = hypothenuze * sin \alpha \\ adjacent = hypothenuze * cos \alpha [/tex]

We insert numbers and we get solution:
[tex]opposite = 80 * sin 25 = 33.8miles \\ adjacent = 80 * cos 25 = 72.5miles [/tex]

How large in square meters is the land area of australia (2941526 mi 2)?

Answers

2941526 mi^2
 The first thing you should know to solve this problem is the following conversion:
 1mi = 1609.34m
 Applying the conversion we have:
 2941526 * (1609.34 / 1) ^ 2 = 7.61848E + 12 m ^ 2
 Answer: 
 The land area of Australia in square meters is:
 7.61848E + 12 m ^ 2

Final answer:

The land area of Australia is roughly 7.62 trillion square meters, calculated by multiplying the area in square miles (2,941,526) by the conversion factor of 2,590,000 square meters per square mile.

Explanation:

The student is asking for the conversion of Australia's land area from square miles to square meters. To convert square miles to square meters, we use the conversion factor that 1 square mile is equal to 2.59 square kilometers or 2,590,000 square meters. Therefore, the land area of Australia in square meters is calculated by multiplying the area in square miles by the conversion factor:

2,941,526 mi2 × 2,590,000 m2/mi2 = 7,619,652,340,000 m2

The land area of Australia is approximately 7.62 trillion square meters.

If the arrival of major road vehicles can be described by the poisson distribution, and the peak hour volume is 1000 veh/hr. the value of the critical gap is 4 seconds. the expected number of available gaps during the peak hour is equal to:

Answers

expected no. of vehicles per hour = 1000
expected no. of vehicles per 4 minute interval = 1000/(3600/4) = 10/9 = &lambda;

Using the poisson distribution, probability that no vehicles within the 4 second interval
P(0)= &lambda; ^0 e^(- &lambda; )/ 0!
= (10/9)^0 e^(-10/9) / 1
= e^(-10/9)
= 0.3292 (approx.)

In an hour, there are n=3600/4=900 such intervals, each with probability of p=0.3292 occurring.

Applying binomial distribution,
expected number of gaps
=np
=900*0.3292
= 296.3

Answer: the expected number of gaps is 296 (to the nearest unit).


Note: in fact, the actual expected number will be higher because gaps do not line up at 4 second intervals.  If a vehicle passes at the 1 second of the interval, a gap can commence at the next second.  Therefore the expected value could/should be slightly higher.

it is definitely an isosceles triangle. when you plot it in a graph you will see that AB=BC=CA or AC.All the sides will be equal.

The triange may be classified as (2) isosceles triangle

How to classify the triangle?

The vertices are given as:

A(0,0), B(3,2), and C(0,4)

Calculate the side lengths using:

d = √(x2 - x1)^2 +(y2 - y1)^2

So, we have:

AB = √(3 - 0)^2 +(2 - 0)^2

AB = √13

AC = √(0 - 0)^2 +(4 - 0)^2

AC = 4

BC = √(3 - 0)^2 +(2 - 4)^2

BC = √13

Side lengths BC and AB are equal

i.e. AB = BC = √13

Hence, the triange may be classified as (2) isosceles triangle

Consider a normal population distribution with the value of σ known. (a) what is the confidence level for the interval x ± 2.88σ/ n ? (round your answer to one decimal place.) % (b) what is the confidence level for the interval x

Answers

By dividing the observations with σ and by subtracting the mean of the distribution, we can transform any normal distribution into the standard one with mean 0 and standard deviation of one. In this case, this means that we need to find the confidence interval of (-2,88, 2,88) for the standard normal distribution. We can look this up in a standard table; The probability that an observation is below -2,88 is 0,002 and the probability that it is below 2,88 is 0,998. Hence, we have that 0,996 of the observations is in this interval, thus 99,6% is the confidence level of the given interval.
Final answer:

The confidence level for the interval x ± 2.88σ/√n is approximately 99.9%. The term 'confidence level' speaks to how frequently the true value of the parameter would be inside the interval for replicated experiments. Without additional information, we cannot compute the confidence level for just 'x'.

Explanation:

In statistics, a formula exists to find the confidence interval. For the interval x ± 2.88σ / √n, the confidence level is nearly 99.9%. We find this by referring to the z-table (standard normal table) with a z-score of 2.88. This leaves 0.05% in each tail of the distribution.

On the topic of confidence levels, a 95% confidence interval implies that if you were to take 100 random samples from your population, approximately 95 of those samples would capture the true population parameter.

For the other part of your question, when we talk about the interval x, it doesn't provide enough detail to calculate a confidence level. It needs to be stated in context of the standard deviation and the sample size.
