Data can be displayed in many different ways: using tables, graphs, and equations. What are the benefits and drawbacks of each of these models?
Answers
Answer:
There are many different ways to portray your findings for an individual to view and understand. However, each have their pros and cons. When using a table, all of the specific numbers of your data can clearly be seen and compared with one another without having to analyze a picture. However, since there is no visual correlation that shows the growth and decline of your data, someone who best comprehends visually may not be able to understand your findings. It sis best to vary your sources of displaying information to make sure that it is all able to be understood by any viewer. When using a graph, you have a clear visual representation of the correlation of your variables in your experimentation. This allows the viewer to comprehend your data as a picture and see the change as the picture moves. However, it take further analysis and cross referencing to get specific quantitative data as you are required to read across and down the graph. And finally, when using equations you can show the direct way that the change was caused in your experiment. Each equation has a specific input and output. However, the drawback is the person viewing your data may have to solve the equations themselves to find out your data or simply be confused as equations don’t directly show data, but rather how to find it. It is important to have a varied combination of these things to allow for your data to be throughly understood by anyone viewing it. I hope this helps! :)

Write the quadratic equation in Standard From whose graph has the following: x-intercepts: 2, 5 passes through the point (4, -2) Group of answer choices
Answers
The equation of the quadratic equation is y = x² - 7x + 10.
What is x-intercept of a graph?
The points where a line crosses x- axis and y- axis are known as the x-intercept and the y-intercept, respectively.
Given that the x-intercepts of the graph are 2 and 5.
If a and b x-intercepts of a graph, then the equation of the graph is y = A(x -a)(x - b).
Assume the equation of the quadratic equation will be y = A(x -2)(x - 5).
The graph is passes through the point (4, -2).
Putting x = 4 and y = -2 in the equation y = A(x -2)(x - 5)
-2 = A(4 -2)(4 - 5)
-2 = -2A
A = 1
The equation of the quadratic equation is y = (x -2)(x - 5)
y = x² - 7x + 10.

Express the confidence interval 0.555 < p < 0.999 in the form p+E
Answers
In order to express the confidence interval in the form p ± E, first we have to determine the midpoint of the interval, like this:
[tex]\hat{p}=\frac{0.555+0.999}{2}=0.777[/tex]The value of the error, E, can be calculated by taking the difference between p and the end of the interval, like this:
[tex]E=0.999-0.777=0.222[/tex]Then, we can express 0.555 < p < 0.999 in p + E notation as 0.777 ± 0.222
The confidence interval can be written as 0.777 ± 0.222.
The confidence interval 0.555 < p < 0.999 can be expressed in the form of p ± E.
To find the margin of error (E), we can subtract the lower limit (0.555) from the upper limit (0.999) and divide it by 2:
E = (0.999 - 0.555) / 2
E = 0.222
Therefore, the confidence interval 0.555 < p < 0.999 can be expressed as:
p ± E
where p is the point estimate and E is the margin of error. In this case, the point estimate would be the midpoint of the interval, which is the average of the lower and upper limits:
p = (0.555 + 0.999) / 2
p = 0.777
Hence, the confidence interval can be written as 0.777 ± 0.222.

Given that 1+i is a root of the equation
x³ + 2x² + λx + μ = 0,
(a) find the values of the real constants λ and μ,
(b) find all the other roots of the equation.
[10]
Answers
(a) The values of the real constants λ and μ are -6 and 8, respectively.
(b) The roots of the equation are (1 + i), (1 - i), and -4.
We are given an equation. The equation is cubic in nature. It means the equation has three roots. The equation is given below.
x³ + 2x² + λx + μ = 0
One of the roots of the equation is given to us. The known root is "1 + i". The given root is a complex root. We know that complex roots occur in conjugate pairs. So, another root of the equation is "1 - i". Let the third root be represented by the variable "a". We can form the factors as given below.
[x - (1 + i)][x - (1 - i)](x - a) = 0
[x² - x(1 - i) - x(1 + i) + (1 + i)(1 - i)](x - a) = 0
[x² - x + ix - x - ix + (1² - i²)](x - a) = 0
[x² - 2x + (1 + 1)](x - a) = 0
(x² - 2x + 2)(x - a) = 0
x³ - ax² - 2x² + 2ax + 2x - 2a = 0
x³ - (a + 2)x² + (2a + 2)x - 2a = 0
This equation must be the same as the given equation. Now we will compare the coefficients of different powers of "x".
First, we compare the coefficient of x².
2 = -(a + 2)
a + 2 = -2
a = -4
Now, we compare the coefficient of x.
λ = 2a + 2
λ = 2*(-4) + 2
λ = -8 + 2
λ = -6
Now we compare the constant terms.
μ = -2a
μ = -2*(-4)
μ = 8

A street light is at the top of a 17ft tall pole. A woman 6ft tall walks away from the pole with a speed of 4ft/sec along a straight path. How fast is the tip of her shadow moving when she is 45ft from the base of the pole?
Answers
A woman 6 ft tall walks away from a 17 ft tall pole with a street light on top of it.
Graphically:
From the diagram, we can say that:
[tex]\frac{x}{6}=\frac{y}{11}\ldots(1)[/tex]The laws of motion of the woman and the shadow with respect to the base of the pole are:
[tex]\begin{gathered} y(t)=y_0+v_y\cdot t \\ x(t)=x_0+v_x\cdot t \end{gathered}[/tex]Where x0 and y0 are the initial positions, vx and vy are the shadow speed and the speed of the woman, respectively. We know that vy = 4 ft/s, so if we say that the starting point for the woman was 11 feet away from the pole, then using equation (1):
[tex]\begin{gathered} y_0=11 \\ \frac{x_0}{6}=\frac{y_0}{11}\Rightarrow x_0=6 \end{gathered}[/tex]Then, the laws of motion are:
[tex]\begin{gathered} y(t)=11+4\cdot t \\ x(t)=6+v_x\cdot t \end{gathered}[/tex]We now calculate the instant of time when y = 45 ft. Using the law of motion of the woman:

The total distance covered by catherine is 10 miles as the problem says, " Catherine drives to school each day and lives 5 miles away. After school, she drives to Kroger , which is 2 additional miles away from her house. Then she heads home and studies for a test before having dinner".
What is distance?Distance is defined as an object's total movement without regard for direction. Distance can be defined as how much ground an object has covered regardless of its starting or ending point. The magnitude or size of displacement between two positions is defined as distance. The distance between two points differs from the distance traveled between them. The total length of the path traveled between two points is referred to as the distance traveled. Travel distance is not a vector. Distance refers to "how much ground an object has covered" while moving, whereas displacement refers to how far an object is out of place. Displacement is a Vector quantity, whereas distance is a Scalar quantity.
Here,
The total distance from home to school=5 miles
She goes to kroger that is 2 miles from her home,
so, 5-2=3 miles
So she travels 3 miles back from school.
Then she goes 2 miles from kroger to home.
5+3+2=10 miles
According to the problem, Catherine's total distance traveled is 10 miles "Catherine lives 5 miles away and drives to school every day. She drives to Kroger after school, which is two miles away from her house. She then returns home to study for a test before eating dinner ".
