Use the box plots comparing the number of boy dogs and number of girl dogs attending doggy daycare each day for a month to answer the questions.
The boxplots 1 and 2 represent the distribution of data using a five number summary for the male and the female attendance
(a) The IQR of the male's dataThe first box plot represents the male's boxplot.
So, we have:
Upper quartile (Q3) = 14Lower quartile (Q1) = 2The IQR is the difference between the above values
IQR = Q3 - Q1
So, we have:
IQR = 14 - 2 = 12
So: the IQR for the males' data is 12
(b) The difference in the median valuesFrom the first and second boxplots, we have:
Median male = 10Median female = 18The difference (d) between these values is
d = 18 - 10
d = 8
So: the difference between the median values of each data set is 8
(c) The distribution of dataThis is dependent on whether the dataset has an outlier or not.
From the figure, we have:
Male's data: presence of an outlier - use medianFemale's data: absence of an outlier - use meanSo: the male dataset is measured by median, while the mean is a better measure of center for the female's data
(d) Reason for outliersA possible reason for outliers is sampling problems

Yellow Bird launches from point (10,0). His flight path reaches a maximum height of 22 yards and lands at point (42, 0).
The Equation for the launch of the yellow bird is y = -0.1( x - 26 )² + 20
what will be the equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values
Given:
Starting position of the bird = ( 10 , 0 )
Final position of the bird = ( 42 , 0 )
Maximum Height of the bird = 20 yards
To find: Equation that represent this condition.
Clearly, Birds flight path is not a straight line. It has a curved path.
So, the path bird follow is a PARABOLA.
Standard Equation of the parabola in vertex form, y = a( x - h )² + k
where ( h , k ) is the vertex of the parabola.
In our Question , vertex is the point at the highest position.
Vertex will be 20 yard above the mid point of the starting and final position.
Using Mid-Point Formula,
Mid-Point of ( 10 , 0 ) & ( 42 , 0 ) =
Now, the vertex = ( 26 , 0 + 20 ) = ( 26 , 20 )
⇒ Equation, y = a( x - 26 )² + 20
Now, we find value of by substituting value of (10 , 0) in the equation,
⇒ 0 = a( 10 - 26 )² + 20
a( -16 )² = -20
a(256) = -20
a = -20/256
a = −0.078125
a ≈ -0.1
Therefore, The Equation is y = -0.1( x - 26 )² + 20

Polygon ABCDE is reflected to produce polygon ABCDE. What is the equation for the line of reflection?
ОА У-0
OB. X=0
OC x=2
OD. y=1
Answer:
B. x = 0
Step-by-step explanation:
we notice that a point and it’s image have the same y-coordinate and opposite x-coordinates
Example :
A(-2 , 2) is a point and A(2 , 2) it’s image by the reflection
[tex]y_{A}=2=y_{A^{\prime }}[/tex]
[tex]x_{A}=-2=-x_{A^{\prime }}[/tex]
Then the reflection is across the y-axis

a. Horror is the most popular genre.
b. Drama is the most popular genre.
c. People like comedies because they like to laugh.
d. People don’t like horror movies because they don’t like to be scared.
Answer:
B. Drama is the most popular genre
Step-by-step explanation:
Day 1:⇒ Comedy: 5
Drama: 7
Action: 3
Horror: 1
Day 2:⇒ Comedy: 2
Drama: 11
Action: 4
Horror: 5
With this information we can start ruling out our answer choices.A. horror is the most popular genre
Lets see, both of the sum of both days for Horror is 6, for Action is 7, Drama is 18, and Comedy is 7, with this we can conclude that horror is actually the least popular genre
B. Drama is the most popular genre
Using the information we gathered previously, we know Drama is the most popular genre, therefore this option is a high possibility.
C. People like comedies because they like to laugh
Although, I personally love comedies for this reason, this chart does not prove that people like comedies for this reason.
D. People don't like horror movies because they don't like to be scared
As for option C, the chart does not prove that is the case!
Therefore we can conclude that option B is the best choice.

James sees a truck at the dealership for $50,000
base price, $1,400 premium interior, $1,700
navigation touch-screen, and $2,200 smart
traffic sensors. If his current vehicle is worth
$5,000 and he's offered a 80% trade-in rate,
what is the total cost of the car after the $1,200
destination fee?
A. $41,900
B. $52,500
C. $51,500
D. $56,500
The total cost of the car after the $1,200 destination fee is B. $52,500.
How to calculate the total cost?To calculate the total cost of the car after the trade-in rate and the destination fee, we shall subtract the trade-in value from the total price of the new car, and then add the destination fee.
Given:
Base price of the car = $50,000
Premium interior = $1,400
Navigation touch-screen = $1,700
Smart traffic sensors = $2,200
Total price before the trade-in
= $50,000 + $1,400 + $1,700 + $2,200 = $55,300.
The trade-in rate = 80% of the trade-in value, which is $5,000.
So, the trade-in value = 80% * $5,000 = $4,000.
Subtract the trade-in value from the total price:
$55,300 - $4,000 = $51,300.
Finally, add the destination fee of $1,200 to the destination fee:
Total cost of the car = $51,300 + $1,200
= $52,500.
Therefore, the total cost of the car after the $1,200 destination fee is $52,500.

Find the value of the expression.
cos(-pi/12)
What would -pi/12 be the sum or difference of?
Notice that
1/6 - 1/4 = -1/12
Then
cos(-π/12) = cos(π/6 - π/4)
cos(-π/12) = cos(π/6) cos(π/4) + sin(π/6) sin(π/4)
cos(-π/12) = (√3/2) (1/√2) + (1/2) (1/√2)
cos(-π/12) = (√6 + √2)/4

Which equation does NOT represent a vertical asymptote of the graph of y=tanθ?
A. θ=-pi/2
B. θ=0
C. θ=pi/2
D. θ=3pi/2
The value of theta where we do not have a vertical asymptote is θ = 0.
Where we do not have a vertical asymptote?
The vertical asymptotes happen when the denominator becomes equal to zero.
For our case, we have:
tan(θ) = sin(θ)/cos(θ).
So the vertical asymptotes are for the values of θ where the cosine is equal to zero. Particularly, cos(0) = 1, then in θ = 0 the denominator is not equal to zero, which means that at that value we do not have an asymptote.
Then the correct option is B.
