Final answer:
Yes, a segment can have more than one bisector. A bisector divides a segment into two equal parts.
Explanation:
Yes, a segment can have more than one bisector. A bisector of a segment is a line, segment, ray, or plane that divides the segment into two equal parts. Each bisector intersects the segment at its midpoint. Since the definition of a bisector doesn't specify uniqueness, there can be infinitely many bisectors of a given segment, especially in a two-dimensional plane.
For example, if you have a horizontal line segment, you could have one vertical bisector that divides it in the middle, but you could also have an infinite number of bisectors at various angles that also pass through the midpoint. Thus, there are multiple bisectors for any given line segment. Thus, consider two points A and B on a straight line segment AB. According to geometric principles, you can draw a perpendicular bisector that would be unique in the sense that it's the only line that both bisects AB and is perpendicular to it

Find the diameter of a cone that has a volume of 83.74 cubic inches and a height of 5 inches. use 3.14 for pi. (1 point) 3 inches 4 inches 8 inches 16 inches
Answer: 8 inches
Step-by-step explanation:
The volume of a cone is given by :-
[tex]\text{Volume}=\dfrac{1}{3}\pi r^2 h[/tex], where r is radius and h is height of the cone.
Given : The volume of cone = 83.74 cubic inches
The height of cone = 5 inches
Then by using the above formula , we have
[tex]83.74=\dfrac{1}{3}(3.14) r^2 5\\\\\Rightarrow\ r^2=\dfrac{3\times83.74}{3.14\times5}\\\\\Rightarrow\ r^2=16.0012738854\approx16\\\\\Righatrrow\ r=\sqrt{16}=4\text{ inches}[/tex]
Diameter of cone = [tex]2r=2(4)=8\text{ inches}[/tex]
Hence, the diameter of cone = 8 inches

Step-by-step explanation:
The height of 18-year-old men are approximately normally distributed, with mean of 68 inches and a standard deviation of 3 inches. what is the probability that an 18-year-old man selected at random is between 67 and 69 inches tall? round your answer to the nearest thousandths place (3 places).the height of 18-year-old men are approximately normally distributed, with mean of 68 inches and a standard deviation of 3 inches. what is the probability that an 18-year-old man selected at random is between 67 and 69 inches tall? round your answer to the nearest thousandths place (3 places).
The probability of an 18-year-old man selected at random being between 67 and 69 inches tall is approximately 0.261.
Here's how we can calculate this:
Standardize the values: Convert the heights of 67 inches and 69 inches to z-scores using the formula:
z = (x - mean) / standard deviation.
In this case, z for 67 inches is -0.33 and z for 69 inches is 0.33.
Calculate the area between the z-scores: Using a standard normal distribution table or calculator, find the area between -0.33 and 0.33. This represents the probability of an 18-year-old man having a height within that range.
Round the answer: The calculated area is approximately 0.261, which is the probability of a randomly selected man being between 67 and 69 inches tall.
Therefore, the probability of an 18-year-old man selected at random being between 67 and 69 inches tall is approximately 0.261.
The probability that an 18-year-old man selected at random is between 67 and 69 inches tall is approximately 0.259.
To find the probability that an 18-year-old man selected at random is between 67 and 69 inches tall, we first need to standardize the values using the z-score formula:
[tex]\( z = \frac{x - \mu}{\sigma} \)[/tex]
where x is the value
[tex]\( \mu \)[/tex] is the mean, and
[tex]\( \sigma \)[/tex] is the standard deviation.
For x = 67 inches: [tex]\( z = \frac{67 - 68}{3} = -0.333 \)[/tex]
For x = 69 inches: [tex]\( z = \frac{69 - 68}{3} = 0.333 \)[/tex]
Using the standard normal distribution table or calculator, we find the corresponding probabilities:
P(z < -0.333) and P(z < 0.333)
P(z < -0.333) = 0.3707 and P(z < 0.333) = 0.6293
To find the probability between 67 and 69 inches, we subtract the smaller probability from the larger:
0.6293 - 0.3707 = 0.2586
Solve the system of equations by substitution. x + y = x + 7y = 8

The dot plot shows the number of words students spelled correctly on a pre-test. Which statement best describes the shape of the graph?
A.) The graph is skewed right.
B.) The graph is nearly symmetrical.
C.) The graph is skewed left.
D.) The graph is perfectly symmetrical.
Let's think of this problem easily by looking at it instead of going through rigorous mathematics.
When a graph is skewed right, most of the values are to the left side.
When a graph is skewed left, most of the values are to the right side.
Perfectly symmetrical is that both sides, with respect to the median, are same. Here mean and median is equal.
Nearly symmetrical would really close to perfect symmetry, only varying a bit on both sides. Mean would be approximately equal to median.
Now counting the dots as well as looking closely, we can rule out skewed right and skewed left. Now, is the graph perfectly symmetrical? No! So the correct answer is "nearly symmetrical". Correct choice is B.
ANSWER: B
Answer:
The answer is neary symmetrical or answer B
Step-by-step explanation:
If you cut the graph in half exactly, both side would almost line up perfectly.
A reflecting telescope is purchased by a library for a new astronomy program. The telescope has a horizontal parabolic frame and contains two mirrors, 3 inches apart from each other- the first in the base and the second at the focal point. The astronomy teacher would like to attach a digital monitoring system on the edge of the telescope, creating a straight line distance above the focal point. Assuming that the telescope is placed on the edge of the roof in such a way that it is parallel to the ground, the position of the monitoring system, in relationship to the distance between the base and the focal point is modeled by the equation, x = 1/12y2 (x = the distance between the base and the focal point; y= the height of the monitoring system).
Rewrite the model so that the height of the digital monitoring system is a function of the distance between the base and the focal point of the telescope. How high above the focal point is the digital monitoring system attached to the telescope? Include your function and the height, rounded to the nearest tenth of an inch, in your final answer.
The digital monitoring system attached at 6 inch from telescope.
What is Parabola?A curve produced by the intersection of a cone's surface with a plane perpendicular to a straight line; a curve produced by a moving point whose distance from a stationary point is equal to its distance from a fixed line.
Here, we have a parabolic frame with the focus point and on the tip from the stem coming from its center, the digital monitoring system.
So, the equation that in this situation is
x = y² / 12
12x = y²
y= √12x
So, at x= 3 the y will be
y = √12(3)
y = √36
y = 6
Thus, the digital monitoring system attached at 6 inch from telescope.

write a function g whose graph represents a translation 2 units to the right followed by a horizontal stretch by a factor or 2 on the graph of f(x)=|x|
The graph of the function g(x) = 2(|x - 2|) represents a translation 2 units to the right followed by a horizontal stretch by a factor of 2 on the graph of f(x) = |x|.
Explanation:To represent a translation 2 units to the right followed by a horizontal stretch by a factor of 2 on the graph of f(x) = |x|, we can define the function g(x) as g(x) = 2(|x - 2|).
The function |x - 2| represents the translation 2 units to the right, while the factor of 2 in front of the absolute value represents the horizontal stretch by a factor of 2.
For example, when x = 1, g(x) = 2(|1 - 2|) = 2(|-1|) = 2.

True or false the opposite angles of a quadrilateral in a circumscribed circle are always complementary
Answer: This statement is false.
Step-by-step explanation:
False, the opposite angles of a quadrilateral in a circumscribed circle is not complementary.
As we know that the sum of opposite angles of a cyclic quadrilateral ( quadrilateral circumscribed circle ) is always supplementary.
So, Sum of opposite angles is 180° .
Hence, this statement is false.
Answer:
False
Step-by-step explanation:
We are given that
Opposite angles of a quadrilateral in a circumscribed circle are always complementary.
We have to find that this statement is true or not.
We know that
When a quadrilateral in a circumscribed circle is called cyclic quadrilateral.
We know that
Sum of opposite angles of cyclic quadrilateral is always 180 degrees.
When sum of two angle is equal to 180 degrees then , the angles are called supplementary.
Hence, the sum of opposite angles of cyclic quadrilateral is always supplementary.
Therefore, the given statement is false.

A bacteria culture starts with 120 and after 3 hours the population consists of 200 bacteria. What is the rate of the increase to the nearest percent?
The rate of the increase would be 18.56% to the nearest percent.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Seema obtained a score of 57% on her exam, that corresponds to 67 out of 100.
We have been given 120 bacteria to start, which increases to 200 bacteria in 3 hours.
The population-increasing formula is given by
⇒ P(n) = P₀(1+ r)ⁿ
Here P(n) = 200, P₀ = 120, and n = 3
Substitute the values in the above equation,
⇒ 200 = 120(1+ r)³
⇒ 200 / 120 = (1+ r)³
⇒ 5/3 = (1+ r)³
⇒ ∛5/3 = 1+ r
⇒ ∛5/3 - 1 = r
⇒ r = 0.18563
⇒ % r = 18.56%
Therefore, the rate of the increase would be 18.56% to the nearest percent.

The rate of increase for a bacteria culture that starts with 120 bacteria and grows to 200 after 3 hours is calculated by dividing the increase in population (80) by the initial population (120) and then multiplying by 100 to get the percentage. The rate of increase is 66.67%, which rounds to 67% to the nearest percent.
To find the rate of increase to the nearest percent for a bacteria culture that starts with 120 bacteria and grows to 200 bacteria after 3 hours, we must calculate the percentage growth over the time period given.
First, we need to find the absolute increase in the number of bacteria:
Final population - Initial population = Increase in population
200 - 120 = 80
Next, we calculate the rate of increase based on the initial population:
(Increase in population / Initial population)
(80 / 120)
Multiplying by 100 to get the percentage: (80 / 120) ×100
Rate of increase = 66.67%
Rounded to the nearest percent, the rate of increase is 67%
