Angela says she drew a square, and
the square shows 2/2of a whole. Draw to show how
the whole could look. Describe how you decided
how the whole could look.
To decide how the whole could look, I used the information given in the statement that Angela drew a square representing 2/2 of a whole. This tells me that Angela's square represents the entire whole.
What is the square about?If Angela drew a square that shows 2/2 of a whole, it means that the square represents the entire whole.
To show how the whole could look, we can draw a larger square around Angela's square. This larger square would represent the whole, and Angela's square would be a part of it.
Based on this information, I determined that the whole could be represented by a larger square that encompasses Angela's square. The size of the larger square would be such that the area of Angela's square is equal to 1 whole unit, since Angela's square represents 2/2 or 1 whole unit of the whole.
Therefore, I drew a larger square that has the same area as 1 unit and enclosed Angela's square within it. This larger square represents the entire whole, and Angela's square is a part of it. (Image attached)

In a class of 52 students, 13 excel in Science and Mathematics, 16 excel in Science and Arts, 12 excel in Mathematics and Arts, 24 excel in Arts and 2 excel in none. Twice as many students excel in science only as do in mathematics only. The number of students who excel in mathematics only is six times the number of students who excel in Arts only. Determine the number of students who excelled in: (a) All the three subjects (b) Two subjects
14 students excel in all three subjects.
How to solveLet's use the Principle of Inclusion-Exclusion to solve this problem.
Let A be the set of students excelling in Arts, B be the set of students excelling in Science, and C be the set of students excelling in Mathematics.
|A| = 24, |B| = 16, |C| = 13
|A ∩ B| = 16, |B ∩ C| = 13, |A ∩ C| = 12
Let x be the number of students who excel in all three subjects.
|A ∩ B ∩ C| = x
We are given that 2 students excel in none of the subjects.
So, |A ∪ B ∪ C| = 52 - 2 = 50
Using the Principle of Inclusion-Exclusion:
|A ∪ B ∪ C| = |A| + |B| + |C| - |A ∩ B| - |B ∩ C| - |A ∩ C| + |A ∩ B ∩ C|
Substituting the given values, we get:
50 = 24 + 16 + 13 - 16 - 13 - 12 + x
Solving for x, we get:
50 = 24 - 12 + x
x = 38 - 24
x = 14
So, 14 students excel in all three subjects.

Rectangle ABCD is dilated by a scale factor of 1/4 to form A'B'C'D. Point T is the center of dilation and lies on line segment AB as shown. In A'B'C'D. line segment A'B has a slope of ____ and a length of _____.
In A'B'C'D, line segment A'B has a slope of 0 and a length of 5/4
Calculating the slopes and the lengths of the segment A'B'From the question, we have the following parameters that can be used in our computation:
A = (1, 4) and B = (6, 4)
The line AB is a horizontal line that passes through the point y = 4
This means that the slope of the segment A'B' is 0
The length is then calculated as
A'B' = difference in the x-coordinate * scale factor
Substitute the known values in the above equation, so, we have the following representation
A'B' = (6 - 1) * 1/4
Evaluate
A'B' = 5/4
Hence, the length A'B' is 5/4

You are told that h is a one to one function with values h(-9)=5 and h(3)= -4 which of the following is true
If function "h" is one-to-one function which is having values h(-9) = 5, and h(3) = -4, then the inverse statement is (d) h⁻¹(-4) = 3.
We know that the function "h" is a one-to-one function, so, it has an inverse function (h⁻¹). To find the inverse function, we need to exchange roles of "x" and "y" and solve for y. This gives:
x = h(y)
y = h⁻¹(x)
The given values of function "h" are h(-9) = 5 and h(3) = -4, we find the values of h⁻¹(5) and h⁻¹(-4):
h(-9) = 5
So, h⁻¹(5) = -9 (by exchanging roles of x and y)
and h(3) = -4
So, h⁻¹(-4) = 3 (exchanging the roles of x and y)
The function "h⁻¹(-4) = 3" is represented in option (d).
Therefore, the correct option is (d).

Therefore, the probability that the team wins the debate is 0.6475.
In order to simulate the probability that a Sophomore is never selected to give the closing argument in the next 5 debates, we can use the following steps:
Create a table of random digits with enough rows and columns to simulate the 5 debates. Each row represents a debate and each column represents a team member.
Assign the digits 0, 1, and 2 to represent the events that a sophomore, junior, and senior gives the closing argument, respectively.
Starting from the first row and first column, read the digits from the table and determine which team member gives the closing argument for the first debate.
If a sophomore is selected, record a 0 for that debate. Otherwise, record a 1.
Repeat steps 3 and 4 for the remaining debates, filling in the table as you go.
Calculate the proportion of simulations where a Sophomore is never selected to give the closing argument in the next 5 debates.

The graph of line T passes throug the points listed beow.
(a,-b)and (-C,d) Line s is parallel to linet. What is the slope of line s?
Therefore, the slope of line s is equal to (d + b) / (a - c).
What is slope?In mathematics, the slope is a measure of the steepness of a line. It is defined as the ratio of the vertical change (rise) between two points on the line to the horizontal change (run) between those same two points. In other words, the slope is the change in the y-coordinate divided by the change in the x-coordinate. If the slope is positive, the line is increasing from left to right and has an upward direction. If the slope is negative, the line is decreasing from left to right and has a downward direction. If the slope is zero, the line is horizontal. If the slope is undefined, the line is vertical. The concept of slope is important in various fields of mathematics, science, and engineering, as it helps to describe the relationship between two variables and make predictions based on that relationship. It is also used in calculus to find the rate of change of a function, and in geometry to find the equation of a line or the angle between two lines.
Here,
Since line s is parallel to line t, it has the same slope as line t. The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) can be calculated using the formula:
slope = (y₂ - y₁) / (x₂ - x₁)
In this case, the points on line t are (a, -b) and (-c, d), so the slope of line t is:
slope of t = (d - (-b)) / (-c - a)
slope of t = (d + b) / (a - c)
Since line s is parallel to line t, it has the same slope as line t:
slope of s = (d + b) / (a - c)

What is the equation of a circle?In Mathematics and Geometry, the standard form of the equation of a circle is represented by the following mathematical equation;
(x - h)² + (y - k)² = r²
Where:
h and k represents the coordinates at the center of a circle.r represents the radius of a circle.Note: A center that lies on the y-axis simply means the value of h on the x-axis is equal to 0.
Based on the information provided above, we have the following parameters:
Radius, r = √[(3 - 5)² + (2 - 4)²] = √8
Center, (h, k) = (3, 2).
By substituting the given parameters into the equation of a circle formula, we have the following;
