What is the difference between a Bimodal Histogram and a Symmetric Histogram?
The main difference is that a Bimodal Histogram has two peaks representing the most frequent data values, whereas a Symmetric Histogram has one peak and its data is evenly distributed around a central value. In a symmetric histogram, mean, median, and mode coincide, unlike in a bimodal distribution, where the modes are different from the mean and median.
Explanation:The difference between a Bimodal Histogram and a Symmetric Histogram relates to the distribution of data within the histogram.
A Bimodal Histogram has two distinct peaks or modes, indicating two prevalent data values within the dataset.
In contrast, a Symmetric Histogram is characterized by a single peak, with the data points arranged evenly around a central value such that it creates a mirror image on either side of the peak.
Symmetric histograms often indicate that the mean, median, and mode of the dataset coincide at the center of the distribution.
However, in a symmetric distribution with bimodality, the modes will differ from the mean and median.
When data is skewed to the left or right, it is not symmetric, and the mean, median, and mode do not align, with the mean being pulled towards the tail of the distribution in skewed datasets.
To visualize these concepts, one may create a histogram by plotting the frequency of data points against specified ranges.
Bimodal histograms will show two high-frequency areas, while symmetric histograms will show a single, central peak, indicating where the bulk of the data lies.
In playing from the tee, a golfer hooks his drive (hits the ball to the left of the correct direction) at an angle of 24 from the intended direction. He estimates that he has driven the ball 215 yards and that it lies 100 yards from the hole. Assuming his estimates are correct, what is the distance from the tee to the hole, to the nearest yard?
Answer:
245 yards
Step-by-step explanation:
Answer:
245 yards
Step-by-step explanation:
You could say the tee is at (0, 0) and the hole lies on the x-axis.
The path of the ball is the straight-line so, y = tan(24°)x
215cos(24°) = 196.4
215sin(24°) = 87.4
The ball lands at coordinates (196.4, 87.4).
They say the ball lands 100 yards from the hole, the hole is on a circle of radius 100 that is centered at (196.4, 87.4).
Equation of the circle:
(x-196.4)² + (y-87.4)² = 100²
Since the hole is on the x-axis, it lies at the intersection of the circle and the line y = 0 so:
(x - 196.4)² + (0 - 87.4)² = 100²
x = 244.92
The distance between tee and hole is 245 yards.
The area of a triangle piece of stained glass is 50 centimeters if the height of the triangle is four times the base, how long are the height and base of the piece of stained glass
Answer:
Base = 5 cm
Height = 20 cm
Step-by-step explanation:
Points to remember
Area of triangle = bh/2
Where b - base of triangle
h - Height of triangle
To find the Height and Base of given triangle
It is given that,area of a triangle piece of stained glass is 50 centimeters
the height of the triangle is four times the base
h = 4b
Area = bh/2
50 = (b * 4b)/2
100 = 4b²
b² = 100/4 = 25
b =√25 = ±5
b = 5 then h = 4b = 4 * 5 = 20
Base = 5 cm and Height = 20 cm
ANSWER
base=5 cm, height = 20cm
EXPLANATION
The area of a triangle is
[tex]A = \frac{1}{2} bh[/tex]
From the question, A=50 and h=4b
We substitute into the formula to get;
[tex] \frac{1}{2} b \times 4b =5 0[/tex]
This implies that,
[tex]2 {b}^{2} = 50[/tex]
[tex] {b}^{2} = 25[/tex]
Take positive square root to get;
[tex]b = \sqrt{25} [/tex]
[tex]b = 5[/tex]
The base is 5 cm and the height is 20 cm.

A point located at (-5, -6) is reflected over the y-axis. What are the coordinates of the image? (-5, 6) (5, -6) (5, 6) (-6, -5)
ANSWER
The image is located at (5,-6)
EXPLANATION
The rule for reflection over the y-axis is to negate the x-coordinates.
This implies that,
[tex](x,y)\to (-x,y)[/tex]
If the point located at (-5, -6) is reflected over the y-axis, the coordinates of the image is obtained by negating the x-coordinate.
Therefore
[tex]( - 5, - 6)\to (5, - 6)[/tex]
The image is located at (5,-6)
Answer:
The correct answer option is (5, -6).
Step-by-step explanation:
We are given the following coordinates of a point:
[tex] ( - 5 , - 6 ) [/tex]
If this point is reflected through y axis, what will be the coordinates of its image?
Reflection through y-axis means that the sign of the x coordinate will be changed so we get:
[tex] ( - 5 , -6 ) [/tex] [tex] \implies [/tex] (5, -6)
Consider the two functions shown below.
ANSWER
B. The functions f(x) and g(x) because f(g(x))=g(f(x))=x
EXPLANATION
The given functions are:
[tex]f(x) = 2x - 2[/tex]
and
[tex]g(x) = \frac{1}{2}x + 1[/tex]
If f(x) and g(x) are inverses, then
f(g(x))=x
[tex]f(g(x))=f( \frac{1}{2} x + 1)[/tex]
[tex]f(g(x))=2( \frac{1}{2}x + 1) - 2[/tex]
Expand the parenthesis to obtain,
[tex]f(g(x))=x + 2- 2[/tex]
[tex]f(g(x))=x[/tex]
Also,
[tex]g(f(x)) = g(2x - 2)[/tex]
[tex]g(f(x)) = \frac{1}{2} (2x - 2) + 1[/tex]
[tex]g(f(x)) = x - 1+ 1[/tex]
[tex]g(f(x)) = x [/tex]
Hence f(x) and g(x) are inverses
Answer: Option B
Then The functions f(x) and g(x) are inverses because [tex]f(g(x))=g(f(x))=x[/tex]
Step-by-step explanation:
To answer this question we must make the composition of f (x) and g (x)
We found
[tex]f (g(x))[/tex]
We know that
[tex]f(x) = 2x-2\\\\g(x) = \frac{1}{2}x + 1[/tex]
By definition if two functions f and g are inverses then it follows that:
[tex]f(g(x)) = g(f(x)) = x[/tex]
So if [tex]f(g(x)) = x[/tex] f and g are inverse
To find [tex]f(g(x))[/tex] enter the function g(x) within the function f(x) as shown below
[tex]f(g(x))= 2( \frac{1}{2}x + 1)-2\\\\f(g(x))= x + 2 -2\\\\f(g(x))= x[/tex]
Now
[tex]g(f(x))= \frac{1}{2}(2x-2) + 1\\\\g(f(x))= x-1 + 1\\\\g(f(x))= x[/tex]
Observe that
[tex]f(g(x))=g(f(x))=x[/tex]
Then The functions f(x) and g(x) are inverses because [tex]f(g(x))=g(f(x))=x[/tex]
A manufacturer is designing a two-wheeled cart that can maneuver through tight spaces. On one test model, the wheel placement (center) and radius are modeled by the equation (x+2)^2+(y-0.5)^2=16. Which graph shows the position and radius of the wheels?
Answer:
The answer is the attached figure
Step-by-step explanation:
* Lets revise the equation of the circle
- The center-radius form of the circle equation is
(x – h)² + (y – k)2 = r², where the center is the point (h, k)
and the radius is r.
- This form of the equation is helpful, since you can easily find the
center and the radius.
* Now lets solve the problem
- The equation of the circle is (x + 2)² + (y - 0.5)² = 16
* Lets compare it with form above
∵ (x - h)² = (x + 2)²
∴ -h = 2 ⇒ × -1
∴ h = -2
∵ (y - k)² = (y - 0.5)²
∴ -k = -0.5 ⇒ × -1
∴ k = 0.5
∴ The center of the circle is (-2 , 0.5)
∵ r² = 16 ⇒ take √ for both sides
∴ r = √16 = 4
∴ The radius of the circle is 4 units
* Now lets look to the answer to find the circle whose center is
(-2 , 0.5) and radius 4 units
∴ The answer is the attached figure
* From the graph:
- The center of the circle is (-2 , 0.5)
- The horizontal diameter is between -6 and 2, then the length
of the diameter = 2 - -6 = 8
∵ The radius = 1/2 the diameter
∴ The raduis = 1/2 × 8 = 4 units

A basketball is thrown upwards. The height f(t), in feet, of the basketball at time t, in seconds, is given by the following function: f(t) = −16t2 + 44t + 12 Which of the following is a reasonable domain of the graph of the function when the basketball falls from its maximum height to the ground?
Answer:
Reasonable domain is [1.375,3].
Step-by-step explanation:
Given function is [tex]f\left(t\right)=-16t^2+44t+12[/tex].
Now we need to find about what is the reasonable domain of the graph of the function [tex]f\left(t\right)=-16t^2+44t+12[/tex] when the basketball falls from its maximum height to the ground.
Compare with [tex]at^2+bt+c[/tex], we get a=-16 and b=44
then t-coordinate of vertex [tex]t=-\frac{b}{2a}=-\frac{44}{2\left(-16\right)}=1.375[/tex]
Then that means maximum height of the ball occurs when time t=1.375 seconds.
Now let's find time when ball falls on ground so set f(t)=0
[tex]f\left(t\right)=-16t^2+44t+12[/tex]
[tex]-16t^2+44t+12=0[/tex]
[tex]4t^2-11t-3=0[/tex]
[tex]\left(4t+1\right)\left(t-3\right)=0[/tex]
[tex]4t+1=0[/tex] or [tex]t-3=0[/tex]
[tex]4t=-1[/tex] or [tex]t=3[/tex]
[tex]t=-0.25[/tex] or [tex]t=3[/tex]
Time can't be negative so we use t=3 only
Hence reasonable domain is [1.375,3].

A ferry is carrying 600 vehicles, including trucks and passenger vehicles. The fees collected total $29,200. The charge per Truck is $100. The charge per passenger vehicle is $45. How many trucks and how many passenger vehicles is the ferry carrying?
Let m be the no of trucks and n be the no of passenger vehicles...
Then m + n = 600
and 100m + 45n = 29200
Multiplying 1st equation by 45, we have 45m+45n=27000
then subtracting from 2nd eqn we have, 55m = 2200 that is m=40.Then n=560
So we have 40 trucks and 560 passenger vehicle

Plsssss help !!!!!! At certain traffic light 10% of the cars passed through have four wheel drive what percentage do not have four wheel drive? Apex
Answer:
90%
Step-by-step explanation:
If you are going to find out the percent of the car that do not have 4 wheel drive, you take the total amount of car that passed though the stoplight which is 100% . You take this 100% and then subtract the 10% to get the final answer 90%. 90% of the cars do not have 4 wheel drive.
To find the percentage of cars without four-wheel drive, subtract the percentage of cars with four-wheel drive from the total. Since 10% of cars have four-wheel drive, 90% do not.
If 10% of the cars have four-wheel drive, then the percentage of cars without four-wheel drive is the remainder when the total percentage (100%) is reduced by the percentage of those that do have four-wheel drive.
To calculate this, we subtract the percentage of cars with four-wheel drive from the total percentage:
100% - 10% = 90%
Therefore, 90% of the cars do not have four-wheel drive.

which event has a probability closest to 1? Choosing a boy randomly in a class of 10 boys and 10 girls, drawing a heart randomly out of a pile of 4 hearts and 8 spades, correctly choosing a random number between 1 and 10, choosing a girl randomly in a class of 8 girls and 12 boys
Answer:
Choosing a boy randomly in a class of 10 boys and 10 girls
Step-by-step explanation:
The probability of choosing a boy randomly in a class of 10 boys and 10 girls is calculated as;
(number of boys)/ (total number of students in the class)
= 10/(10+10) = 10/20 = 1/2
The probability of drawing a heart randomly out of a pile of 4 hearts and 8 spades is calculated as;
4/(4+8) = 4/12 = 1/3
The probability of correctly choosing a random number between 1 and 10 is simply 1/10 since the numbers are have a uniform distribution and thus equally likely to be selected.
The probability of choosing a girl randomly in a class of 8 girls and 12 boys is calculated as;
(number of girls)/ (total number of students in the class)
= 8/20 = 2/5
Thus choosing a boy randomly in a class of 10 boys and 10 girls is the event which has a probability closest to 1.
Final answer:
Out of the given events, choosing a boy randomly in a class of 10 boys and 10 girls has the highest probability, which is 0.5. Therefore, this event's probability is closest to 1.
Explanation:
To answer which event has a probability closest to 1, we need to calculate the probability of each event:
Choosing a girl randomly in a class of 8 girls and 12 boys has a probability of
8 girls / (8 girls + 12 boys) = 8/20 = 2/5 or 0.4.
Comparing these probabilities, choosing a boy randomly in a class of 10 boys and 10 girls has the highest probability, which is 0.5. Therefore, this event has a probability closest to 1.
