When dropped, a super ball will bounce back to 80% of its peak height,continuing on in this way for each bounce.
For example, if a super ball is dropped from 20 feet, the first bounce will be
16 feet high. The second bounce will be 12.8 feet high.
Question: Write an expression for the height of the nth bounce.
An expression for the height of the nth bounce is 0.80X^N = Height.
EquationsSince when dropped, a super ball will bounce back to 80% of its peak height, continuing on in this way for each bounce, to determine an expression for the height of the nth bounce the following calculation must be performed:

What is the largest possible value x could take given that it must be an integer? x < 2
The largest possible value x could take given that it must be an integer for x < 2 is 1.
Difference between an inequality and an equation?The key distinction between an inequality and an equation is that an inequality describes a connection of inequality between two expressions, whereas an equation expresses equality between two expressions. In other words, an inequality shows that one expression is more or less than the other expression, but an equation shows that two expressions have the same value.
The highest number x might have is 1 if x must be an integer and x 2. This is due to the fact that any number higher than one would break the inequality x 2, and any number between one and two that is not an integer would also violate the stipulation that x must be an integer.

Explain the term matched-paired sampling?Paired testing, commonly referred to as auditing, is a practical and easy technique to determine whether and how discrimination is present.
In a paired exam, two individuals are given fictional identities and credentials that are equivalent in all significant ways.Each member of such a sample is paired with a matching member in every sample by comparison to characteristics other than those that are now the subject of the research. This results in a pair or set of matched samples.By "removing" the potential impacts of other variables, matching aims to produce better estimates of differences.The participants in matched samples (also known as matched pairs, paired samples, or dependent samples) were paired up so that they share all characteristics except the one that is being studied.Thus, µD ≥ 0,HA: µD < 0, is used to determine whether the first population's mean is lower than the second population's mean, a set of hypotheses.

In order to estimate the typical amount of TV watched per day by students at her school of 1,000 students, a student has all of the students in her statistics class (30 students) take a short survey, finding that, on average, students in her statistics class report watching 12 hours of television per day 2110 Use the previous information to answer the following questions. (2) What is the population of interest? (b) Do you believe that the average hours of television per day in the sample is likely less than, similar to, or greater than the average hours of television watched per day in the population? Why? Use the previous information to answer the following questions about the class survey (2) Describe in words the parameter of interest (b) Identify the numeric value of the statistic corresponding to the above parameter Use the previous information to answer the following questions about the class survey (a) Identify the variable measured on each student ) is the variable categorical or quantitative? (c) Identify at least two statistics that the student could use to summarize the variable (d) Identity at least one graph that the student could use to summarize the variable
The population of interest is all students at the school, not just the 30 students in the statistics class who were surveyed.
The average hours of television per day in the sample is likely not representative of the average hours of television watched per day in the population. This is because the sample only consists of 30 students from the statistics class, which may not be a diverse and random representation of the entire school population.
The parameter of interest is the average hours of television watched per day by all students at the school.
The numeric value of the statistic corresponding to the above parameter is 12 hours.
The variable measured on each student is the number of hours of television watched per day.
The variable is quantitative, as it involves numerical values.
Two statistics that the student could use to summarize the variable are mean and median. The mean would give the average hours of television watched per day, while the median would provide the middle value in the data, which can help understand the central tendency of the data.
One graph that the student could use to summarize the variable is a histogram. A histogram would show the distribution of the data, which can help visualize how the hours of television watched per day are spread across the sample.

Use Euler's Method with a step size of h−0.1 to approximate y(0.3) where y(x)
is a solution to the initial given value problem:
y′=(x−y)2 given y(0)=0.5
Approximate y(0.3) to approximately 0.41818 using Euler's method with a step size of h.
Euler's strategy is one of the most important and simple approaches to settling differential conditions. Linear approximations are used in this first-order approach to solving differential equations. The technique depends on the likelihood that, at different places, we can make little, straight approximations to the game plan to surmised the response for a differential condition.
We have been given the values y(0)=0.5 and y(x)y′=(xy)2. We are told to utilize Euler's technique with a stage size of h0.1 to estimated y(0.3).
Euler's overall strategy is as follows:
This formula can be used to approximate the value of y at x=0.1, 0.2, and 0.3 given that y′ = (x y)2, and f(x_i, y_i) = (x_i - y_i)2 y_i+1 = y_i + h*f(x_i, y_i), where f(x_i, y_i) is the subordinate of y as for x
y(0.1) = 0.5 + 0.1*(0-0.5)2 = 0.475; y(0.2) = 0.475 + 0.1*(0.1-0.475)2 = 0.44846; y(0.3) = 0.44846 + 0.1*(0.2-0.44846)2 = 0.41818; Consequently, we are able to approximate y(0.3) to approximately 0.41818 using Euler's method with a step size of h.

Find the composite function N(T(t)):
N(T(t))=
Find the time when the bacteria count reaches 9197.
Time Needed = hours
The composite function N(T(t)) is given by N(T(t)) = 22(8t+1.4)^2 - 58(8t+1.4) + 6.
To find the composite function N(T(t)), we substitute the expression for T(t) into the equation for N(T).
N(T(t)) = 22T^2 - 58T + 6 [Substitute T(t) = 8t+1.4]
N(T(t)) = 22(8t+1.4)^2 - 58(8t+1.4) + 6 [Expand and simplify]
N(T(t)) = 22(64t^2 + 22.4t + 1.96) - 58(8t+1.4) + 6 [Expand further]
N(T(t)) = 1408t^2 + 387.2t + 43.12 - 464t - 81.2 + 6 [Combine like terms]
N(T(t)) = 1408t^2 - 76.8t - 31.08 [Simplify]
Now, to find the time when the bacteria count reaches 9197, we set N(T(t)) equal to 9197 and solve for t.
1408t^2 - 76.8t - 31.08 = 9197 [Set N(T(t)) = 9197]
1408t^2 - 76.8t - 9218.08 = 0 [Rearrange equation]
Solving this quadratic equation will give us the value(s) of t when the bacteria count reaches 9197.

PLEASE HELP ASAP!!!! Give one example of how it is possible for a 9th degree function to have 2 real solutions and 4 imaginary.
Answer:
It is not possible for a 9th degree polynomial to have exactly 2 real solutions and 4 imaginary solutions.
By the Fundamental Theorem of Algebra, a polynomial of degree n has exactly n complex roots, counting multiplicities. Since 2 + 4i is a complex number, it can only be a root of a polynomial of degree 1 (a linear function) or higher.
If a 9th degree polynomial has 2 real roots, then it must have 7 complex roots (counting multiplicities). These complex roots can be either purely imaginary or have non-zero real and imaginary parts. However, it cannot have exactly 4 purely imaginary roots and 3 with non-zero real and imaginary parts, since complex roots of a polynomial occur in conjugate pairs. Therefore, it is not possible for a 9th degree polynomial to have exactly 2 real solutions and 4 imaginary solutions.

The time it takes for the object to reach its maximum height is 4 seconds.An equivalent expression to this one: -3.5x + 0.2 + 0.8x + 3x + 0.4 is -3.5x + 4.2
Given that s(t) = –4.9t² + 39.2t represents an object launched from ground level directly upward at 39.2 m/s. To find the time it takes for the object to reach its maximum height, we have to use the following formula: t = -b/2aHere, a = -4.9, b = 39.2. The equation can be written as: s(t) = –4.9t² + 39.2t = -4.9(t² - 8t)
Using the complete the square method: -4.9(t² - 8t + 16) = -4.9(t - 4)² + 78.4We observe that the maximum height occurs when t = 4. Hence, we substitute t = 4 in the equation s(t) and find the maximum height.s(4) = -4.9(4)² + 39.2(4) = 78.4 mHence, the time it takes for the object to reach its maximum height is 4 seconds.An equivalent expression to this one: -3.5x + 0.2 + 0.8x + 3x + 0.4 is -3.5x + 4.2

A student wonders if people of similar heights tend to date each other. She measures herself, her dormitory roommate, and the women in the adjoining rooms, then she measures the next man whom each woman dates. Here are the data (heights in inches): Women: 64 65 65 66 66 70 Men: 68 68 69 70 72 74 Determine whether each of the following statements is true (T) orfalse (F). (a) If we had measured the heights of the men and women in centimeters (1 inch= 2.54 cm), the correlation coefficient would have been 2.54 times larger. (b) There is a strong negative association between the heights of men and women because women are always smaller than the men they date. (c) There is a positive association between the heights of men and women.
Answer:
(a) False
(b) False
(c) True
Step-by-step explanation:
(a) If we had measured the heights of the men and women in centimeters (1 inch= 2.54 cm), the correlation coefficient would have been 2.54 times larger.
No, since changing the units of measurement does not change the correlation coefficient
(b) There is a strong negative association between the heights of men and women because women are always smaller than the men they date.
Negative association means that as one variable increases, the other decreases, Here, we see that as the heights of the men increase, the height of the women do not reliably decrease, hence there is no strong negative asscoiation
(c) There is a positive association between the heights of men and women.
We see from the values given that as the heights of men increase, so do the heights of women and vise versa, so there is a positive association between the heights of men and women

The speed of a point on the wheel rim is 35000π cm/s (2500 rev/min and 14cm diameter).
what is circumference ?
Circumference is the distance around the edge of a circle. It can be calculated using the formula: C = 2πr, where C is the circumference and r is the radius of the circle.
To express the speed of a point on the rim of the wheel in centimeters per second, we first need to find the circumference of the wheel using the diameter. The circumference can be found using the formula: C = 2πr, where C is the circumference and r is the radius of the wheel.
Since the diameter is 14cm, the radius of the wheel is 14/2 = 7cm.
Therefore, the circumference of the wheel is: C = 2π(7) = 14π cm
Next, we need to find the distance traveled by a point on the rim of the wheel in one revolution. This distance is equal to the circumference of the wheel.
So, the distance traveled by a point on the rim of the wheel in one revolution is: 14π cm
To find the speed in centimeters per second, we need to multiply the distance traveled in one revolution by the number of revolutions per minute.
The wheel rotate 2500 revolution per minute.
The speed of a point on the wheel rim is 35000π cm/s (2500 rev/min and 14cm diameter).

Answer:
Q.1 360° Q.2 360°
Step-by-step explanation:
Q.1 let the third angle of the triangle be a
70°+40°+a=180(by angle sum property)
110°+a=180
a=180°-110°
a=70°
angle x=70°+x=180°(linear angle)
x=180°-70°
x=110°
angle z= 40°+z=180
z= 180°-40°
z=140°
angle y=a+y=180°
70°+y=+80°
y=180°-70°
y=110°
y+z+x=110° +110° +140°=360
Q.2 let the fourth angle of the quadrilateral be x
120°+70°+60°+ x=360° (by angle sum property)
250°+x=360°
x=360°-250°
x=110°
angle a=120°+a=180°(by linear angle)
a=180°-120°
a=60°
angle b=70°+b=180°
b=180°-70°
b=110°
angle c=x+c=180°
110° + c=180°
c=180°-110°
c=70°
angle d=60°+d=180°
d= 180° -60°
d=120°
a+b+ c+d=120°+110°+60°+70°=360°
