So Reena has ran a distance of 5 kilometers while only covering one-sixth of the distance.
What is equation?In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10.
Here,
If Reena has completed one sixth of the 30 km run,
30 km / 6 = 5 km.
So, Reena has run a distance of 5 km so far when she had run one sixth of the distance.

Find the volume of a cylinder that has a diameter of 14 mm and a height of 8 mm.
Use = 3. 14 and round your answer to the nearest hundredth
The volume of the cylinder with a diameter of 14 mm and a height of 8 mm is approximately 1230.88 mm³.
The volume of a cylinder can be calculated using the formula:
V = πr²h
where r is the radius of the cylinder and h is its height. To find the volume, we first need to find the radius, which is half of the diameter:
r = 14 mm / 2
= 7 mm
Now that we have the radius, we can plug it into the formula along with the height to find the volume:
V = π * (7 mm)² * 8 mm
= 3.14 * 49 * 8 mm³
= 1230.88 mm³

How do I do this question?
Answer:
y=-1/4x+2
Step-by-step explanation:
y=mx+c
1st point : (-4,3)
2nd point : (4,1)
m= rise/run
= 3-1/-4-4
= 2/-8
= -1/4
y=-1/4x+2
Answer: y = -1/4[tex]x[/tex] + 2
Step-by-step explanation:
The equation of any line is y = mx + c, where:
m = gradient of the line
c = y-intercept (the point where the line goes through the y-axis)
So, to make this line into an equation, we first find the gradient. To calculate the gradient, we have to find the [tex]\frac{rise}{run}[/tex] .To do this, we take 2 points from the line that are whole numbers and put it into this equation. So, we can take (0,2) & (4,1). Since we have this, we can sort of draw an imaginary triangle. Now we find the rise, which is 1, and the run, which is 4. So we know the gradient is [tex]\frac{1}{4}[/tex], but since its a line going downwards, it will have a negative gradient meaning it is [tex]-\frac{1}{4}[/tex] .
For the y-intercept, we can see that the line intercepts/crosses the y-axis at (0,2), so the y-intercept is 2. So we have the equation:
[tex]y = - \frac{1}{4}x + 2[/tex]

Solve the system of linear equations by substitution.
y=4x
x+y=-10
By substituting the linear equations, we know that the value of x and y are -2 and -8 respectively.
What are linear equations?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included.
The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
Ax+By=C is the usual form for two-variable linear equations.
A standard form linear equation is, for instance, 2x+3y=5.
When an equation is given in this format, finding both intercepts is rather simple (x and y).
So, we have the equation:
y=4x ...(1)
x+y=-10 ...(2)
Now, substitute y = 4x in equation (2):
x+y=-10
x+4x=-10
5x = -10
x = -10/5
x = -2
Then, substitute x = -2 in equation (1):
y = 4x
y = 4(-2)
y = -8
Therefore, by substituting the linear equations, we know that the value of x and y are -2 and -8 respectively.

What is permutation ?
In mathematics and statistics, a permutation refers to a way of arranging a set of objects in a particular order. More specifically, a permutation is an arrangement of a set of distinct objects in a specific order. For example, if we have the set {1, 2, 3}, there are six possible permutations: {1, 2, 3}, {1, 3, 2}, {2, 1, 3}, {2, 3, 1}, {3, 1, 2}, and {3, 2, 1}.
In permutations, the order of elements matters, which means that changing the order of any of the elements will result in a different permutation. Permutations are used in many areas of mathematics and statistics, including combinatorics, probability theory, and group theory. They are also used in computer science and cryptography for generating random sequences and encryption keys.
According to given conditions:
The number of observations refers to the number of data points or cases that you have in your dataset. For example, if you're collecting data on the heights of people in a certain population, each person's height measurement would be considered one observation.
A sample size, on the other hand, refers to the number of observations that you have included in your sample from the larger population. For example, if you're taking a random sample of 100 people from a population of 10,000, your sample size would be 100.
The number of elements typically refers to the number of individual items or units that you're measuring or counting. For example, if you're counting the number of cars in a parking lot, the number of elements would be the total number of cars.
The number of variables refers to the number of characteristics or attributes that you're measuring for each observation. For example, if you're collecting data on people's heights, weights, and ages, you would have three variables.
Finally, the population size refers to the total number of individuals or units in the population that you're interested in studying. This may or may not be relevant depending on the type of analysis you're doing. If you're conducting a sample survey, for example, the population size would be important to determine the appropriate sample size.
The number of observations will always be the same as the sample size. Therefore, the answer is A.

u^3 + 8 factors as (u + 2)(u^2 + 2u + 4) is explained by kuta software infinite algebra as
x^3 + 125
To factor this expression, we can use the formula for the difference of cubes:
a^3 + b^3 = (a + b)(a^2 - ab + b^2)
We can set a = x and b = 5:
x^3 + 125 = (x + 5)(x^2 - 5x + 25)
So x^3 + 125 factors as (x + 5)(x^2 - 5x + 25).
a^3 + 64
To factor this expression, we can use the formula for the sum of cubes:
a^3 + b^3 = (a + b)(a^2 + ab + b^2)
We can set a = a and b = 4:
a^3 + 64 = (a + 4)(a^2 + 4a + 16)
So a^3 + 64 factors as (a + 4)(a^2 + 4a + 16).
x^3 - 64
To factor this expression, we can use the formula for the difference of cubes:
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
We can set a = x and b = 4:
x^3 - 64 = (x - 4)(x^2 + 4x + 16)
So x^3 - 64 factors as (x - 4)(x^2 + 4x + 16).
u^3 + 8
To factor this expression, we can use the formula for the sum of cubes:
a^3 + b^3 = (a + b)(a^2 + ab + b^2)
We can set a = u and b = 2:

do you think it would be unusual for an individual to pay a tax of less than $7700? explain. assume the variable is normally distributed. round the answer to at least four decimal places.
The distribution was skewed or had other non-normal characteristics, it would be more difficult to make a definitive statement about the probability of paying less than $7,700 without additional information.
The probability distribution of a variable that is normally distributed is bell-shaped, with the majority of observations centred around the mean and decreasingly more observations as you travel away from the mean. The mean and standard deviation of the variable influence the shape of the distribution.
We may use the characteristics of the normal distribution to calculate the likelihood that a person would pay less than $7700 in taxes if we assume that the variable in question is normally distributed. To perform this computation, we would need to know the variable's mean and standard deviation.
For instance, if we were aware that the average tax paid by individuals was $10,000 with a $2,000 standard deviation, we could use a calculator or table of the standard normal distribution to estimate the likelihood that a person would pay less than $7,700. As $7,700 is more than two standard deviations below the mean, if the distribution were totally normal, we could argue that it would be exceedingly unusual for an individual to pay less than that amount. Without more information, it would be more challenging to make a firm determination regarding the likelihood of paying less than $7,700 if the distribution was skewed or had other non-normal characteristics.

Answer: Let's call the rainfall in the second half of the month "x".
From the first half of the month, we know that the total rainfall was 1/5 inch.
At the end of the month, we know that the total rainfall was 1/2 inch:
1/5 + x = 1/2

Explain how the successive values of a geometric sequence could become infinitesimally small but never be equal to 0. Include an example.
The value of a geometric sequence can not be zero, because for that we have to include 0 as a term in it and that will turn the sequence into zero.
What is geometric sequence?A geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
In geometric sequences, the terms given by the ratio of every two successive terms is a constant. they can be either negative or positive but not zero, because if any term will be zero it will directly make the common ratio equal to 0, that will make the sequence turning to 0, and it won't be a geometric progression anymore, therefore, the successive values of a geometric sequence could become infinitesimally small but never be equal to 0.
An example of a Geometric sequence is 2, 4, 8, 16, 32, 64, …, where the common ratio is 2.
If suppose 2nd term is 0, then common ratio = 0/2 = 0, that will disturb the pattern and the sequence will not be a GP
