Step-by-step explanation:
from point A, draw an arc that intersects both sides of the angle
From point A, draw an arc that intersects both sides of the angles. Thus, the correct option is D.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
An angle bisector is a line or ray that divides an angle into two equal parts. The angle bisector divides the angle into two smaller angles that have the same measure.
Thus, the correct option is D.

Which would best display the following data if you wanted to display the numbers which are outliers as well as the mean? [4, 1, 3, 10, 18, 12, 9, 4, 15, 16, 32]

Answers
The best choice to display the numbers which are outliers as well as the mean for the given data [4, 1, 3, 10, 18, 12, 9, 4, 15, 16, 32] would be a Box-and-Whisker Plot.
In a Box-and-Whisker Plot, the central box represents the interquartile range (IQR), which contains the middle 50% of the data. The line within the box represents the median. Outliers, which are values that lie significantly outside the range of the rest of the data, are depicted as individual points outside the box.
By using a Box-and-Whisker Plot, we can visually identify the outliers in the data set and observe how they deviate from the rest of the values. Additionally, the plot displays the median, which represents the central tendency of the data. This allows us to simultaneously analyze both the outliers and the mean (through the median) in a concise and informative manner.

The missing figure is attached down
Answer:
ΔPAX ≈ ΔYAQ ⇒ proved down
PA × AQ = YA × AX ⇒ proved down
AQ = 7 cm
Step-by-step explanation:
In two triangles: if their corresponding angles have the same measures, then they are similar
In triangles ABC and XYZ, if m∠ABC = m∠XYZ, m∠BCA = m∠YZX, m∠CAB = m∠ZXYThen, ΔABC ≈ ΔXYZIf two triangles are similar, then their corresponding sides are proportion
If ΔABC ≈ Δ XYZ, then\(\frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}\) ⇒⇒⇒ Their sides are proportionIn our question:
From the attached figure
∵ YQ // PX
∴ m∠AYQ = m∠APX ⇒ corresponding angles
∴ m∠AQY = m∠AXP ⇒ corresponding angles
∵ ∠A is a common angle
∴ ΔPAX ≈ ΔYAQ ⇒ proved
∵ ΔPAX ≈ ΔYAQ
∴ Their corresponding sides are proportion
→ side PA is corresponding to side YA
→ side AX is corresponding to side AQ
→ side PX is corresponding to side YG
∴ \(\frac{PA}{YA}=\frac{AX}{AQ}=\frac{PX}{YQ}\)
∵ \(\frac{PA}{YA}=\frac{AX}{AQ}\)
→ By using cross multiplication
∴ PA × AQ = YA × AX ⇒ proved
∵ AX = 14 cm
∵ PA = 6 cm
∵ YA = 3 cm
→ Substitute these values in the relation above
∴ 6 × AQ = 3 × 14
∴ 6 AQ = 42
→ Divide both sides by 6
∴ AQ = 7 cm

Certify Completion Icon Tries remaining: 3 A high school has 52 players on the football team. The summary of the players' weights is given in the box plot. The median weight of the players on the football team is 160 pounds.
The box plot shows that the median weight of the players is the middle value of the distribution. In this case, the median weight is halfway between the 26th and 27th players, which is 160 pounds.
The box plot also shows that the minimum weight of the players is 150 pounds and the maximum weight is 212 pounds. The interquartile range, which is the range of the middle 50% of the data, is 20 pounds.
In conclusion, the median weight of the players on the football team is 160 pounds. This means that half of the players on the team weigh more than 160 pounds and half of the players weigh less than 160 pounds.

Solving a system of equations we can see that he cost of a corn dog is $1.25 and the cost of the fries is $3.50
How to find the cost of each item?We can define two variables here:
x = cost of a corn dog.
y = cost of the fries.
With the information in the question we can write two equations, these two equations form a system of equations that we can solve, the system of equations is the one below:
2x + 3y = 13
4x + y = 8.50
We can isolate y in the second equation to get:
y = 8.50 - 4x
Replace it in the other one:
2x + 3*(8.5 - 4x) = 13
2x + 25.5 - 12x = 13
-10x = 13 - 25.5
x = -12.5/-10 = 1.25
Then:
y = 8.5 - 4*1.25 = 3.5
The cost of a corn dog is 1.25 dollars and the cost of the fries is 3.50 dollars.

Answers
The college will have about 1,440 students who prefer ice cream.
how to calculate number of students who prefer ice cream?To make the prediction about the number of students who prefer ice cream, we need to calculate the percentage of students who prefer ice cream and then use that percentage to estimate the number of students in the whole college who prefer ice cream.
The total number of students surveyed is 81+9+72+36+27=225.
The percentage of students who prefer ice cream is (81/225)×100 ≈ 36%.
Therefore, we can estimate the number of students in the college who prefer ice cream as (36/100)×4000 = 1440.
So, the best prediction about the scoops of ice cream the college will need is that the college will have about 1,440 students who prefer ice cream.

z = 6(x + -1h)
Reorder the terms:
z = 6(-1h + x)
z = (-1h * 6 + x * 6)
z = (-6h + 6x)
Solving
z = -6h + 6x
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Simplifying

Step-by-step explanation:
We can use trig to solve for the missing side (specifically cosine). cos(x)=adjacent side/hypotenuse. We have the x value (which is the angle shown) which is 25. We have the adjacent side of that angle which is 4. We are solving for the hypotenuse (lets call that h). When we plug in values into the equation cos(x)=adjacent/hypotenuse, we get cos(25)=4/h. cos 25=0.9063. So 0.9063=4/h. Multiply both sides by h and we get 0.9063h=4. Now divide 0.9063 on both sides to isolate h and we get 4.4135... but since you want hundredths, its 4.41

The length in centimeters of the side of the square is 8 cm.
What is the area of a rectangle and a square?The surface of a shape's surface is measured by its area. The length and width of a rectangle or square must be multiplied to determine their respective areas. A has a perimeter of x by y. Find the side of the square if the rectangle's length and width are 27 cm and 3 cm, respectively. Given, the area of a square equals the area of a rectangle. The first step is to calculate the rectangle's area using the specified length and width values.
The area of a rectangle and a square are -
A{R} = Length x Breadth
A{S} = Side x Side
Given is that a square and a rectangle have the same area. The length of the rectangle is 32 cm and the width of the rectangle is 2 cm.

In this stem and leaf plot, the median of the data is 6.15 and the range is 8.3.
To find the median and range of the data from the stem and leaf plot, we need to first arrange the data in ascending order.
Arranging the data in ascending order:
1.3, 1.5, 3.2, 3.6, 3.9, 5.4, 5.7, 5.7, 5.8, 5.8, 6.0, 6.3, 6.3, 6.3, 7.4, 7.4, 7.5, 7.6, 8.0, 8.1, 8.1, 8.4, 9.5, 9.6
The median is the middle value of the data set. Since there are 24 values, the median is the average of the 12th and 13th values, which are 6.0 and 6.3. Therefore, the median is (6.0 + 6.3) / 2 = 6.15.
The range is the difference between the largest and smallest values in the data set. The largest value is 9.6 and the smallest value is 1.3. Therefore, the range is 9.6 - 1.3 = 8.3.
Thus, the median of the data is 6.15 and the range is 8.3.
