Of 800 students in a university, 360, or 45%, live in dormitories. the 800 is an example of population size. Population size is a number that represents the total quantity of a particular group of items or people.
In this case, the population size is 800 students in a university. This population size is used to calculate the percentage of students who live in the dormitories. In this example, the percentage of students who live in the dormitories is 45% or 360 students. Population size can be used to analyze different trends or patterns within a group of people.
For example, if the university wanted to determine the number of students who commute from home, they could use the population size of 800 students to calculate the percentage of students who commute from home. Similarly, the university could use the population size to calculate the percentage of students who live off-campus. Population size can also be used to track changes over time.
For example, if the university wanted to determine if the number of students living in the dormitories had increased or decreased since last year, they could compare the current population size of 800 students with the population size from the previous year.

An exact location in space is called a _______ALineBPointCCircleDLine segment
Option B is Correct. An specific place in space is called a point. A dot indicates a point.
A point in space is a location. No length, width, or thickness exist in a point. In geometry, a dot stands in for a point. We typically use a (capital) letter to name a point. The simplest basic geometric object is a point. It is named with a capital letter and symbolised by a dot.
A point has no size and solely represents position (that is, zero length, zero width, and zero height). In a line, a line segment has two distinct endpoints. The line segment's length, which is the separation of two fixed points, is constant.

If 3 sin A + 4 cos A = 5, prove that: tan A + sec A = 2.
Answer: We can start by using the identity sin^2(A) + cos^2(A) = 1.
We can square the equation 3 sin A + 4 cos A = 5, to get:
9sin^2(A) + 12sin(A)cos(A) + 16cos^2(A) = 25
Substituting the identity sin^2(A) + cos^2(A) = 1, we get:
9sin^2(A) + 12sin(A)cos(A) + 16(1-sin^2(A)) = 25
12sin(A)cos(A) = 6
Now,we can use identity tan(A) = sin(A) / cos(A) and sec(A) = 1 / cos(A)
tan(A) = sin(A) / cos(A) = (2sin(A)cos(A)) / (cos^2(A)) = 2 * (sin(A)cos(A)) / (1-sin^2(A)) = 2 * (6 / 12) = 1
sec(A) = 1 / cos(A) = 1 / sqrt(1 - sin^2(A)) = 1 / sqrt(1 - (3/5)^2) = 1 / sqrt(1 - 9/25) = 5/sqrt(16) = 5/4
Now we can add them:
tan(A) + sec(A) = 1 + 5/4 = (4+5) / 4 = 9/4 = 2.25
Hence proved that tan A + sec A = 2.25

What is arithmetic progression ?
An arithmetic progression (AP) can be described in one of two ways:
A sequence known as an arithmetic progression has identical differences between each pair of terms in the sequence.
Arithmetic progressions are sequences where each term, with the exception of the first, is created by multiplying the previous term by a predetermined amount.
The formula for calculating the nth term of an arithmetic progression is expressed as:
Tn = a + (n + 1)d
where a is the first term, d is a common difference.
A linear function is described by the explicit formula below, where n is a positive integer.
f(n) = 5n +12
For the first term
f(1) = 5(1) + 12
f(1) = 17
For the second term
f(2) = 5(2) + 12
f(2) = 22
d = 22 - 17
d = 5

A line passes through the point (6,-1) and has a slope of m=0 Write an equation for the line in point-slope form
Answer:
The proper linear equation is written in following form: y = mx + b (where m is slope, and b is y-intercept). Since we already have the slope, we need to find the y-intercept, b
So we plug in what we have:
y = mx + b
-1 = (-3)(6) + b, where we solve for b
-1 = -18 + b
b = 17
Finally, the equation of the line that passes through point (6, -1) and has a slope of -3 is y = -3x + 17

You want to find the values of the variables in various expressions for angles, sides, or diagonals of parallelograms.
ParallelogramsA parallelogram is a quadrilateral (4-sided polygon) with opposite sides parallel. The opposite sides are also the same length.
Opposite angles in a parallelogram are congruent (have the same measure), and adjacent angles are supplementary (total 180°).
The diagonals of a parallelogram bisect each other, so the halves of a diagonal are the same length.
These are the relationships you need to know in order to solve these problems.
1.Opposite sides are the same length.
XY = WZ
3a -4 = a +2
2a = 6 . . . . . . . . . add 4-a to both sides
a = 3
and ...
YZ = XW
2b = b +1
b = 1 . . . . . . . . . subtract b
2.Opposite angles are congruent.
∠C = ∠A
2y -40 = y +10
y = 50 . . . . . . . . . . add 40-y to both sides
Adjacent angles are supplementary
(y+10) +4x = 180
50 +10 +4x = 180 . . . use the above value for y
4x = 120 . . . . . . . . . . subtract 60
x = 30 . . . . . . . . . . . divide by 4
3.Diagonals bisect each other. Call the center point X where the diagonals cross.
HX = PX
x -3 = 15
x = 18 . . . . . . . add 3
and ...
EX = QX
y +3 = 12
y = 9 . . . . . . . subtract 3
4.Same as problem 3.
NX = LX
4x = x +6
3x = 6 . . . . . . . subtract x
x = 2 . . . . . . . divide by 3
and ...
MX = OX
5y -8 = 3y +1
2y = 9 . . . . . . . . add 8-3y to both sides
y = 4.5 . . . . . . . divide by 2

Annie invests $1500 in a savings account that earns 4% simple interest annually. If she does not make any additional deposits or withdrawals, how much money will be in the savings account after 3 years? (I=prt)
The total amount of money in the savings account after 3 years will be $1,614.00. This is calculated by multiplying $1500 by 1.04 three times, which equals $1,614.00.
1. 1500 x 1.04 = 1560
2. 1560 x 1.04 = 1624.40
3. 1624.40 x 1.04 = 1683.76
4. 1683.76 rounded to two decimal places = $1,614.00
Annie invests $1500 in a savings account that earns 4% simple interest annually. After 3 years, the amount of money in the savings account can be calculated by multiplying the initial investment of $1500 by 1.04 three times. This results in a total of $1,614.00 in the savings account after 3 years, without any additional deposits or withdrawals. This is because 4% simple interest annually means that the interest earned each year is 4% of the initial investment. This is calculated by multiplying the initial investment by 1.04. The 1.04 is the amount of interest earned which is then added to the initial investment. This process is repeated for 3 years, resulting in the total of $1,614.00.

what needs to be included in the label for each axis of a graph? select one or more: name of quantity displayed on axis relationship to quantity displayed on other axis description of how measurement was made units of quantity displayed on axis
Name of quantity displayed on axis and units of quantity displayed on axis.
What is axis?
In a graph, chart, or plot, an axis is a reference line that is used to compare or measure values of a variable along a certain axis. The horizontal (x) axis and the vertical (y) axis are typically the two axes of a two-dimensional graph, and each axis is used to depict a separate variable. The origin, which serves as the beginning point for measuring the variables on the graph, is where the two axes connect. The values of the variables being plotted are represented by the positions of the data points along the axes.
The following details ought to be written next to each axis of a graph when labelling it:
Name of the quantity shown on the axis: This label clearly and succinctly identifies the variable being plotted on the axis. For instance, the label for a time plot on the x-axis can be "Time (seconds)" or just "Time".
Quantity units shown on the axis: The scale for the measurements is provided by this information, which also enables appropriate data interpretation.

A cell is placed in a 15% solute solution and the cell shrinks. What is the tonicity of the 15% solution solution
Answer:
Tonicity is a measure of the concentration of solute particles in a solution compared to another solution. It is used to describe the effects of a solution on a cell.
If a cell is placed in a 15% solute solution and the cell shrinks, it means that the solution is hypertonic to the cell. Hypertonic solutions have a higher concentration of solute particles than the inside of the cell, which causes water to move out of the cell by osmosis. As water leaves the cell, it shrinks.
So, in this case, the tonicity of the 15% solution is hypertonic.
