What is average/mean ?
The middle number, which is determined by dividing the sum of all the numbers by the total number of numbers, is the average value in mathematics. When determining the average for a set of data, we add up all the values and divide this sum by the total number of values.
Given mean [tex]\mu[/tex]=69.5 , S=3

At what point on the curve x = 3t^2 + 5, y = t^3 − 7 does the tangent line have slope 1/2 ?
The tangent line on the curve x = 3t² + 5 , y = t³ - 7 have a slope as 1/2 at the point (8, -6).
The Tangent Line to a curve at a specific point is calculated by the derivative of the curve at that point.
The Slope of the tangent line at a point (x₀, y₀) is given by the derivative of the curve at that point, denoted as f'(x₀).
The curve x = 3t² + 5 , y = t³ - 7 ,
we have to find the value of t such that the slope of the tangent line at that point is 1/2.
we first find the derivative of y with respect to x, which is given by:
⇒ dy/dt = 3t² and dx/dt = 6t
Using chain rule to find the derivative of y with respect to x:
⇒ dy/dx = dy/dt × dt/dx = (3t²)/6t = t/2
Next, we equate derivative to 1/2 and solve for t ;
⇒ t/2 = 1/2
⇒ t = 1
So, the point where the tangent line has slope 1/2 is
⇒ (x, y) = (3t² + 5, t³ - 7)
⇒ (8, -6).
Therefore , the point is (8,-6) .

Two students missed the first Mid exam. Their excuse was that their car had gotten a flat tire. On the next mid exam, these students were asked to identify which tire had become flat (driver's side front, driver's side rear, passenger's side front, passenger's side rear). What is the probability that the two students pick the same tire (assuming the students are randomly choosing)? Submit your answer as a decimal with four digits of accuracy.
Answer:
1/4=0.25
Step-by-step explanation:
The probability that both students pick the same tire is (1/4) * (1/4) = 1/16
The probability of the first student picking a specific tire is 1 in 4, or 1/4. The probability of the second student also picking that same tire is also 1 in 4. To find the probability that both students pick the same tire, we need to multiply the probabilities of each event.
So, the probability that both students pick the same tire is (1/4) * (1/4) = 1/16. This means that the chance of both students picking the same tire is 0.0625 or 6.25%.
To summarize, there are four possible tires that could have gotten a flat, and two students are asked to identify the tire. If each student randomly chooses a tire, the probability that both students will pick the same tire is 1 in 16, or 0.0625. This means that the chance of both students picking the same tire is low, and the likelihood of them choosing different tires is much higher.

The equation for the tangent line to f(x) = ln(x) at x = 2 is y = 1/2x - 1.
1. Start with the equation for a line in slope-intercept form: y = mx + b
2. Substitute in the slope, which in this case is 1/2 since f'(2) = 1/2: y = 1/2x + b
3. Find the y-intercept, which is the point where the line crosses the y-axis. In this problem, we know that f(2) = ln(2), so we can substitute in 2 for x and ln(2) for y in our equation: ln(2) = 1/2(2) + b

At the end of 2018, the world population was approximately 7.53 billion people. This figure is calculated by taking the total population at the end of 2017, 7.4 billion people, and multiplying it by the population growth rate of 1.07%..
This means that the world population increased by approximately 130 million people in 2018. This population growth rate is consistent with the average growth rate of the world population over the last decade. While the population growth rate has been decreasing over the past few decades, it is still relatively high at 1.07%.
The high population growth rate is primarily due to high fertility rates in developing countries and a longer life expectancy in developed countries. This means that more people are born and fewer people die each year. As a result, the total population of the world increases each year.

find the values of X such that the given vectors are orthogonal. xi + 2xj xi - 5j
The values of x that make the given vectors orthogonal are xi = 5 and xi = -2.
The dot product of two vectors is equal to zero when the vectors are orthogonal. Thus, to find the values of X such that the given vectors are orthogonal, we must set the dot product of the two vectors to zero and then solve the resulting equation. The dot product of two vectors is calculated by taking the sum of the product of the corresponding components of the two vectors. In this case, the dot product of the two vectors is calculated as:
(xi + 2xj) • (xi - 5j) = xi2 + 2xixj - 5xi - 10xj
Setting this equal to zero and solving for x, we obtain
xi2 + 2xixj - 5xi - 10xj = 0
Subtracting 2xixj from both sides, we get
xi2 - 5xi - 10xj = -2xixj
Factorizing the left-hand side, we get
(xi - 5)(xi + 2) = -2xixj
Setting the two factors on the left-hand side equal to zero and solving for x, we get
xi - 5 = 0 => xi = 5
and
xi + 2 = 0 => xi = -2
Thus, the values of x that make the given vectors orthogonal are xi = 5 and xi = -2.

What is the w-intercept of the line of fit and its meaning in terms of the scenario?
0.2; a kitten who is just born is predicted to weigh 0.2 ounces
0.2; for each additional day after the kitten is born, its weight is predicted to increase by 0.2 ounces
2.75; a kitten who is just born is predicted to weigh 2.75 ounces
2.75; for each additional day after the kitten is born, its weight is predicted to increase by 2.75 ounces
Answer:
The w-intercept of the line of fit is 2.75, and it means that a kitten who is just born is predicted to weigh 2.75 ounces. This is because the equation of the line of fit is w = 2.75 + 0.2d, where w is the weight of the kitten in ounces and d is the age of the kitten in days. When d = 0, the equation becomes w = 2.75, so the w-intercept is 2.75.

How far is 10 yards in feet?
Answer: 10 yards is equivalent to 30 feet.
Step-by-step explanation:
In 30 feet, there are 10 yards. Therefore 3 feet are equal to 1 yard. To precisely calculate the length in feet, divide 4 yards by 3.
How are yards calculated using dimensions?Let's now convert each of the three dimensions to a yard. How to do it is as follows: Convert the measurement from inches to yards (6 x 36 = 0.167 yards). Do the math to convert 12 feet x 3 into 4 yards. The square yard is equal to the length times the width, expressed in feet, multiplied by 9. (SQYDS).A square yard measures 9 square feet. The area value must be multiplied by 9. You don't need much to change an area from square feet to square yards. For instance, you might divide 27 square feet by 9 to get square yards.Add three to the total number of yards.
Add 10 to 3 since 3 feet are equivalent to 1 yard.

The integrating factor is x³, and the general solution is y = x⁹/12 + C/x³. When putting y(1) = 9, the initial value problem's solution is y = x⁹/12 + 107/12x³.
Now, the equation given to us is:
[tex]y' + 3x^{-1}y = x^8\\[/tex]
Since the equation is not seperable by variables, therefore we have to use the integrating factor method (IF Method).
The ordinary linear differential equations are represented in the following general form:
y’ + P y=Q or dy/dx + P(x) y = Q(x)
Integrating factor is defined as the function which is selected in order to solve the given differential equation. It is most commonly used in ordinary linear differential equations of the first order.
When the given differential equation is of the form;
dy/dx + P(x) y = Q(x)
then the integrating factor is defined as:
μ = [tex]e^{\int{Px} \, dx }[/tex]
where P(x) (the function of x) is a multiple of y and μ denotes integrating factor.
For this equation, the Integrating Factor is:
IF = [tex]e^{3\int{\frac{1}{x} }\, dx }[/tex] = x³
Multiplying both sides of the equation by the IF,
μy' + μ3x^{-1}y = μx^8
x³y' + 3x²y = x¹¹
On solving it, we get the general solution as:
y = x⁹/12 + C/x³
We know that the initial value is y(1) = 9
Substituting y = 9 when x = 1 in the general value,
9 = 1/12 + C/1
C = 9 - 1/12 = 107/12
Therefore, the particular solution is
y = x⁹/12 + 107/12x³
Thus, the integrating factor is x³, and the general solution is y = x⁹/12 + C/x³. When putting y(1) = 9, the initial value problem's solution is y = x⁹/12 + 107/12x³.

(1)a total of 28 ways the student can select 3 writing implements
2)A total of 25 ways the selection be made if no more than one ballpoint pen is selected.
For the first question, the student has three different types of writing implements and thus three different ways to make a selection. The student can choose any combination of three pencils, three ballpoint pens, or three felt-tip pens. This is known as a combination problem and can be solved using the combination formula. The combination formula, which is often written as "n choose k" (where n is the number of objects and k is the number of objects to be selected), can be used to calculate the total number of possible combinations.
In this case, the student has 4 pencils, 3 ballpoint pens, and 1 felt-tip pen, so the combination formula would be (4 choose 3) + (3 choose 3) + (1 choose 3). This simplifies to 28, meaning that there are 28 possible ways the student can select 3 writing implements.
For the second question, the student is limited to selecting no more than one ballpoint pen. Since the student can only select one ballpoint pen, the combination formula would now be (4 choose 3) + (2 choose 3) + (1 choose 3). This simplifies to 25, meaning that there are 25 possible ways the student can select 3 writing implements without selecting more than one ballpoint pen.

h→−2limh3+8h+2 First, rewrite the limit by simplifying the function in the limit as much as you can.
The value of the limit is 12.
A limit in mathematics is a point at which a function approaches the output for the specified input values. Calculus and mathematical analysis depend on limits, which are also used to determine integrals, derivatives, and continuity.
It is employed in the analysis process and constantly considers how the function will behave at a specific moment.
We can expand the cube:
(2+h)³ = 8+12h +6h²+ h³
Plugging this in,
lim (h->0)8+12h +6h²+ h³-8 / h = lim (h->0) 12h +6h²+ h³ / h
=> lim (h->0) (12h +6h+ h²) = 12
The idea of the limit of a topological net broadens the definition of the limit of a sequence and relates it to the limit and direct limit in theory category. In general, there are two sorts of integrals: definite integrals and indefinite integrals. The upper limit and lower limit for definite integrals are correctly specified.

Which r-value suggests a weak negative correlation?
A. r= 0.1847
B. r=-0.1847
C. r= 0.9816
D. r=-0.9816
The r-value which suggests a weak negative correlation is B. r = -0.1847.
What is a negative correlation?In statistics, the term "pattern" or "connection" refers to a pattern or relationship between two variables. The degree to which two variables move in opposition to one another is characterized by a negative correlation. For instance, when X and Y are the two variables, a rise in X causes a reduction in Y. Inverse correlation is another name for a negative correlation coefficient. Scatterplots are used to visualise correlation relationships.
We know that the negative correlation weakens as it moves closer to a positive value. From the given values we see that the weakest negative correlation is r = -1847.
Hence, the r-value which suggests a weak negative correlation is B. r = -0.1847.

A right cone has a height of 12 inches and a volume of 64π in³. What is the radius of the cone?
The radius of the cone is given by the equation r = 4 inches
What is a Cone?A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the center of base) called the apex or vertex.
The volume of a cone is given by the equation
Volume of Cone = ( 1/3 ) πr²h
where r is the radius of the cone
h is the height of the cone
Surface area of the cone = πrl
where l = √ ( b² + r² )
Given data ,
Let the radius of the cone be represented as r
Now , the equation will be
The volume of the cone = 64π inches³
The height of the cone h = 12 inches
So , Volume of Cone = ( 1/3 ) πr²h
Substituting the values in the equation , we get
64π = ( 1/3 )π r² ( 12 )
Divide by π on both sides of the equation , we get
64 = 4r²
Divide by 4 on both sides of the equation , we get
r² = 16
Taking square roots on both sides of the equation , we get
r = 4 inches
Therefore , the value of r is 4 inches
Hence , the radius of cone is 4 inches

The exponential Function is y(t) = 1500 [tex]e^{-0.0.325t[/tex].
What is Exponential Function?Calculating the exponential growth or decay of a given collection of data is done using an exponential function, which is a mathematical function. Exponential functions, for instance, can be used to estimate population changes, loan interest rates, bacterial growth, radioactive decay, and disease spread.
An exponential function is defined by the formula f(x) = [tex]a^x[/tex], where the input variable x occurs as an exponent.
Given:
Forest covered the area of = 1500 Km²
Now, the area is decreased by 3.25%
So, the exponential Function to represent the situation
y(0)= 1500 km², r = -3.25% = - 0.0325
y(t) = A [tex]e^{rt[/tex], and A = y(0) = 1500
so, y(t) = 1500 [tex]e^{-0.0.325t[/tex]
