Which descriptions of a histogram are true? Check all that apply..
A peak is a bar that is lower than the other bars around it.
A peak is where the frequency is lowest.
A peak is where the frequency is the highest.
A cluster is a group of bars, meaning the frequency is higher in these intervals.
A peak is a bar that is higher than the other bars around it.
Intervals on a histogram where there are no bars mean the frequency is 0.
If the graph is symmetrical, the data is clustered toward the right side.
If the graph is symmetrical, the data is evenly distributed.
Answer:
A peak is where the frequency is the highest.
A cluster is a group of bars, meaning the frequency is higher in these intervals.
A peak is a bar that is higher than the other bars around it.
Intervals on a histogram where there are no bars mean the frequency is 0.
If the graph is symmetrical, the data is evenly distributed.
Step-by-step explanation:
The correct statement about histogram is as follows;
A peak is where the frequency is the highest.
A cluster is a group of bars, meaning the frequency is higher in these intervals.
A peak is a bar that is higher than the other bars around it.
Intervals on a histogram where there are no bars mean the frequency is 0.
If the graph is symmetrical, the data is evenly distributed.
We have to determine, which descriptions of a histogram are true?
According to the question,
A histogram meaning can be stated as a graphical representation that condenses a data series into an easy interpretation of numerical data by grouping them into logical ranges of different heights which are also known as bins.
Characteristics of a Histogram are as follows;
A histogram is used to display continuous data in a categorical form.
In a histogram, there are no gaps between the bars, unlike a bar graph.
The width of the bins is equal.
A histogram is a type of representation of a data set where bars are used to represent the frequencies.
The area of these bars is said to be proportional to the frequency of the variable.
The peak of a histogram represents the highest value of frequency. Also, the peak is a bar that is higher than the other bars around it.
In a histogram intervals wherein bars cannot be seen would represent the frequency of that would zero.
Also, if the histogram is said to be symmetrical, then the data should be distributed evenly.
A peak is where the frequency is the highest.
A cluster is a group of bars, meaning the frequency is higher in these intervals.

If the length of AC equals 18, what is the length of the midsection DE
Answer:
The length of the midsegment is 9 ⇒ (B)
Step-by-step explanation:
In a triangle,
The midsegment is the segment which joining the midpoints of two opposite sides of itThe length of the midsegment is half the length of the third side in the triangle which opposite to itLet us use this rule to solve our question
In Δ AC
∵ DE is the midsegment of it
∵ DE is opposite to the side AC
∴ The length of DE = 1/2 the length of AC
∵ The length of AC = 18
∴ The length of DE = 1/2 × 18
∴ The length of DE = 9
∴ The length of the midsegment is 9
The correct answer is B

what equation represents the road that passes through the point shown and is perpendicular to the road represented by the red line
Answer: The equation that represents the road is y= - 1/3x +1/3
Step-by-step explanation:
The perpendicular equation that represents the road that passes through the point is [tex]\mathbf{y = -\frac 13x + \frac 13 }[/tex]
The points of the red line (see attachment) are given as:
[tex]\mathbf{(x,y) = (0,2), (2,8)}[/tex]
Start by calculating the slope (m) of the line using:
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 -x_1}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{8 - 2}{2 -0}}[/tex]
[tex]\mathbf{m = \frac{6}{2}}[/tex]
[tex]\mathbf{m = 3}[/tex]
Next, calculate the slope (m2) of the perpendicular line using:
[tex]\mathbf{m_2 = -\frac 1m}[/tex]
So, we have:
[tex]\mathbf{m_2 = -\frac 13}[/tex]
The perpendicular line passes through point (1,0).
So, the line equation is calculated using:
[tex]\mathbf{y = m_2(x - x_1) + y_1}[/tex]
This gives
[tex]\mathbf{y = -\frac 13(x - 1) + 0}[/tex]
[tex]\mathbf{y = -\frac 13(x - 1) }[/tex]
Open bracket
[tex]\mathbf{y = -\frac 13x + \frac 13 }[/tex]
Hence, the line equation is [tex]\mathbf{y = -\frac 13x + \frac 13 }[/tex]

Answer:
18π
Step-by-step explanation:
Arc length for a parametric equation is:
s = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt
dx/dt = -9 sin(9t)
dy/dt = 9 cos(9t)
s = ∫₀²ᵖⁱ √((-9 sin(9t))² + (9 cos(9t))²) dt
s = ∫₀²ᵖⁱ √(81 sin²(9t) + 81 cos²(9t)) dt
s = ∫₀²ᵖⁱ 9 dt
s = 9t |₀²ᵖⁱ
s = 18π
You can check your answer with geometry. The curve is a circle centered at the origin with radius 1. From 0 to 2π, the particle makes 9 revolutions, or travels 18π radians. So the arc length is 1 × 18π = 18π.

If the radius of a melting snowball decreases at a rate of 5 ins/min, find the rate at which the volume is decreasing when the snowball has diameter 4 inches
Answer:
The rate at which the volume is decreasing when the snowball has a diameter of 4 inches is approximately 251.327 cubic inches per minute.
Step-by-step explanation:
Let suppose that snowball geometry correspond to a sphere. In this case, the volume of the sphere is:
[tex]V = \frac{4\pi}{3}\cdot R^{3}[/tex] (Eq. 1)
Where:
[tex]R[/tex] - Radius of the sphere, measured in inches.
[tex]V[/tex] - Volume of the sphere, measured in cubic inches.
We know that volume decreases due to melting, so we need an expression of the rate of change of volume in time. By differentiating (Eq. 1) we get:
[tex]\frac{dV}{dt} = 4\pi\cdot R^{2}\cdot \frac{dr}{dt}[/tex] (Eq. 2)
Where:
[tex]\frac{dV}{dt}[/tex] - Rate of change of the volume of the snowball in time, measured in cubic inches per minute.
[tex]\frac{dr}{dt}[/tex] - Rate of change of radius of the snowball in time, measured in inches per minute.
If we know that [tex]R = 2\,in[/tex] and [tex]\frac{dr}{dt} = -5\,\frac{in}{min}[/tex], the rate at which the volume of the snowball is decreasing is:
[tex]\frac{dV}{dt} = 4\pi\cdot (2\,in)^{2}\cdot \left(-5\,\frac{in}{min} \right)[/tex]
[tex]\frac{dV}{dt}\approx -251.327\,\frac{in^{3}}{min}[/tex]
The rate at which the volume is decreasing when the snowball has a diameter of 4 inches is approximately 251.327 cubic inches per minute.

Given:
The point P(-2, - 5) is rotated 90° about the origin, and then the image is reflected across the line x= 3.
To find:
The the coordinates of the final image P’’.
Solution:
The point P(-2, - 5) is rotated 90° about the origin. It means the point is rotated 90° counter clockwise about the origin
[tex](x,y)\to (-y,x)[/tex]
[tex]P(-2,-5)\to P'(-(-5),(-2))[/tex]
[tex]P(-2,-5)\to P'(5,-2)[/tex]
Then the image is reflected across the line x= 3.
[tex](x,y)\to (-x+6,y)[/tex]
[tex]P'(5,-2)\to P''(-5+6,-2)[/tex]
[tex]P'(5,-2)\to P''(1,-2)[/tex]
Therefore, the \coordinates of the final image P'' are (1,-2).

solve x^2-12x+36=44 by factoring!!
please help asap with work shown :)
x^2 - 12x + 36 is a perfect square trinomial and can be written as (x-6)(x-6).
(x - 6)^2 = 44.
Take the square root of both sides to get...
x - 6 = ±√44 (Always make the square root + or - when you square root)
Add 6 to both sides...
x = √44 + 6
x = -√44 + 6
These are the 2 values of x.
You can also write it to be -0.633 and 12.633. (Once you round.)
Use the given information to find the measure.
Answer:
From the image, we can see that ∠AOC = ∠AOB + ∠BOC
We are given the following values:
∠AOC = 104
∠AOB = 7x + 30
∠BOC = 9x + 42
Plugging these values in the equation above:
∠AOC = ∠AOB + ∠BOC
104 = 7x + 30 + 9x + 42
104 = 16x + 72
16x = 32
x = 2
Now that we have the value of x, we can easily find the value of ∠BOC
We are given that:
∠BOC = 9x + 42
∠BOC = 9(2) + 42 (since x = 2)
∠BOC = 18 + 42
∠BOC = 60°
Therefore, ∠BOC is 60 degrees

It is given that:
The table below shows the typical hours worked by employees at a company.
Based on the data given:
Total number of hours = 0+ 8.5 + 9.5 + 7.5 + 8 + 8.5 + 4
Total number of hours = 46
Hourly pay = (40×$14) + (6×$21)
Hourly pay = $686 per week
Annual earnings = 52×686
Annual earnings = $35,672
The new employee should select the salary pay based on the calculations above since a $37,000 yearly income is more than a $35,672 hourly wage.
Thus, the new employee should select the salary pay because a $37,000 yearly income is more than a $35,672 hourly wage.
