Solve the following problems IN PENCIL. You must show ALL WORK. Make sure graphs
have Titles and are properly labeled WITH UNITS:
1. Graph the following sample data set showing the distance covered by a runner
during an 800 meter race.
A graph for the data (time and distance) shown in the given table is plotted in the image attached below.
What is a graph?A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
What is a linear function?A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
This ultimately implies that, the data of a linear graph are directly proportional and as such as the value on the x-axis increases or decreases, the values on the y-axis also increases or decreases.
In this exercise, you're required to plot a graph for the data (time and distance) that are recorded for an object that is starting from rest.
By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that the linear function is given by:

What is the Y-Intercept of the line that has a slope of -4 and passes through the point (4,-6)
Answer:
Y-intercept = 22
Step-by-step explanation:
The equation of a line in slope-intercept format is given by the equation y=mx+c
where m is the slope and c the y-intercept.
(The y-intercept is the value of y when x = 0)
Slope given as -4
And we know it passes through the point(4,6) ie at x=4, y =6
Substitute in above equation to get value of c, the y-intercept
6 = -4(4) + c
6 = -16 + c
c = 22
And this is the y-intercept
The equation of the line is y = -4x + 22

Answer:
a) Class A has the larger interquartile range.
b) Class A has the highest test score.
c) Class B has higher median test score.
d) Class B has smaller range of test score.
Step-by-step explanation:
a) Inter quartile range (IQR) = upper quartile - lower quartile
Class A: IQR = 79 - 65 = 14
Class B: IQR = 77 - 70 = 7
Class A has larger interquartile range.
b) Class A has the highest test score.
c) Median of class A = 70
Median of class B = 74
Class B has higher median test score.
d) Range is the difference between the highest and lowest score.
Range = highest score - lowest score
Range of Class A = 85 - 62 = 23
Range of class B = 79 - 68 = 11
Class B has smaller range of test score.

Satia drives for 4 hours from a to b. angelique drives at half the speed of safia. find how many hours angelique takes to drive from a to b
Angelique takes 8 hours to drive from a to b.
What is the concept of speed, distance and time?How quickly something or someone is moving is indicated by their speed. If you know how far something travels and how long it takes, you can calculate their average speed. Speed equals distance x times time, according to the speed formula. Knowing the units for distance and time will help you determine what the units are for speed.
According to given Information:let us assume distance from a to b be x units.
let us assume speed of vehicle be y units/hour.
For case -1For Satia, speed=y units time=4 hours we know the formula of distance is:
distance=speed × time distance=(y× 4) units -------------------(1)
For case - 2Angelique :speed=y / 2 units time=?
We know the formula of distance is:
Distance=speed × time distance=(y/2)× time -------------------(2)
We can see that distance in both cases is equal,
So compare case (1) ad (2) ,
We get (y× 4)=(y/2)× time
On rearranging ,
Time= (4×2) hours=8 hours
hence,
Angelique takes 8 hours to cover the distance from a to b.

18. A surveyor intends to create a bridge across a river. There is a tall tree on the other side of the river. He
measures a line down his side of the river for 125 feet. At each side of this line he uses his surveying
equipment to measure the angle to the tree on the other side of the river. At the beginning of the line, the
angle to the tree was 65°10', at the end of the line the angle to the tree is 60°10'. If he wants the bridge to go
from where he started his line to the tree, then how long will the bridge be?
The 125 feet long line and the angles 65°10', and 60°10' obtained from the surveying equipment gives the length of the bridge as approximately 1234.2 feet.
Which rule can be used to find the length of the bridge?Given;
Location of the tree = The other side of the river from the surveyor
Length of the line measured along the river, L = 125 feet
Angle to the tree from the start of the line = 65°10'
1° = 60'
10' = ((1/60)×10)° = (1/6)°
65°10' = (65 + 10/60)° = (65 + 1/6)°
Angle measured at the end of the line, E = 60°10'
Similarly;
E = 60°10' = (60 + 1/6)°
The interior angle, S, of the triangle formed by the tree and the line, at the start of the line is therefore;
Angle S = 180° - (65 + 1/6)° = (114+5/6)° (linear pair angles)
S = (114+5/6)°
From the angle sum property of a triangle, angle formed at the tree, T, is therefore;
T = 180° - ((114+5/6)° + (60 + 1/6)°) = 5°
According to the rule of sines, we have;
l/(sin T) = b/(sin E)
Where;
b = The length of the bridge
Which gives;
124/(sin 5°) = b/(sin (60 + 1/6)°)
b = (sin (60 + 1/6)°) × (124/(sin 5°)) ≈ 1234.2
The length of the bridge, b ≈ 1234.2 feetLearn more about the rule of sines here:

Given that [tex]MU_{x}/P_{x}[/tex]=30 and [tex]MU_{y} /P_{y}[/tex]=40 of commodities x and y.
Marginal utility is the additional utility that a consumer gets from consuming additional units of commodity. For maximising the utility of the consumer,the ratio of marginal utilities must be equal to the ratio of the products.
There can be two situations in our case:
Because [tex]MU_{x}/P_{x}[/tex]<[tex]MU_{y} /P_{y}[/tex]
So to equalise the ratio we need to reduce [tex]MU_{y} /P_{y}[/tex]. To reduce the utility of y the consumer needs to increase the consumption of y because as the consumption of commodity y increase it decreases the utility of commodity y.
Hence if [tex]MU_{x}/P_{x}[/tex]=30 and [tex]MU_{y} /P_{y}[/tex]=40 then the consumer should buy the commodity y to maximise utility.

A system of linear equations is shown below, where A and B are real numbers.
3x + 4y = A
Bx – 6y = 15
What values could A and B be for this system to have no solutions?
Answer:
A = 0; B = -9/2
Step-by-step explanation:
To have no solutions, you need parallel lines with equal slopes and different y-intercepts.
3x + 4y = A Eq. 1
Bx - 6y = 15 Eq. 2
In Eq. 1, notice that the coefficient of x is 3/4 of the coefficient of y.
We must have the same ratio for the coefficients in Eq. 2.
B/(-6) = 3/4
4B = -6(3)
4B = -18
B = -9/2
Now we have
3x + 4y = A Eq. 1
-9/2 x - 6y = 15 Eq. 2
How do we change the left side of the second equation into the left side of the first equation? -6/4 = -3/2 and also -9/2 ÷ 3 = -3/2
To change the left side of the second equation into the left side of the first equation, divide the left side by -3/2.
If we divide 15 by -3/2 we get -10.
The equation -9/2 x - 6y = -10 is the same as Eq. 1, so that would create a system of equations with only one equation and an infinite number of answers.
To have no equations, the y-intercepts must be different, so A can be any number other that -10.
Answer: A = 0; B = -9/2

so, we actually have
a^((1/4)×12) × b^((1/3)×12) = a³b⁴ = 5000
let's find the prime factors of 5000 :
5000 ÷ 2 = 2500
2500 ÷ 2 = 1250
1250 ÷ 2 = 625
625 ÷ 3 no
625 ÷ 5 = 125
125 ÷ 5 = 25
25 ÷ 5 = 5

E D
The Point E is located at -2.
Given that Point D is located at 4. Point E is 6 less than Point D.
We need to find the location of the point E.
Based on the information provided, Point D is located at 4. Now, we know that Point E is 6 less than Point D.
When we say, "less than," it means we need to subtract the given value from Point D to find the location of Point E.
If Point D is located at 4, and Point E is 6 less than Point D, then the location of Point E can be calculated as follows:
E = D - 6
Since D is 4, we can substitute that value into the equation:
E = 4 - 6
E = -2

Points F(22, 22), G(22, 3), and H(2, 6) are three vertices of
rhombus FGHJ. Vertex J is directly below vertex H.
a. Graph rhombus FGHJ. Label J with its coordinates.
b. What is the perimeter of the rhombus? Show your work.
The perimeter of the rhombus FGHJ is 20 units
How to graph the rhombusThe coordinates are given as:
F = (-2, -2)
G = (-2, 3)
H = (2, 6)
From the question, we understand that vertex J is directly below vertex H.
This means that vertices H and J have the same x coordinate.
So, we have
J = (2, y)
The distance between F and G is 5 units,
So, we have
J = (2, y - 5)
Where
y = 6 i.e. the y coordinate of H
This gives
J = (2, 6 - 5)
Evaluate
J = (2, 1)
See attachment for the graph of the rhombus
The perimeterIn (a), we have:
The distance between F and G is 5 units,
This means that
FG = 5
The side lengths of a rhombus are equal.
So, the perimeter is
P = 4 * FG
This gives
P =4 * 5
Evaluate
P = 20
Hence, the perimeter of the rhombus is 20 units
