What is a logarithm?Generally, A logarithm is a mathematical function that determines the power to which a given number (called the base) must be raised to obtain a certain value. In other words, a logarithm is the inverse operation of exponentiation.
For example, if we take the base 2 and the value 8, the logarithm of 8 to the base 2 (written as log2 8) is 3, because 2 raised to the power of 3 (i.e., 2^3) equals 8.
Logarithms are widely used in many fields of science, engineering, and mathematics, particularly in areas where large numbers or very small numbers are involved. They are also used in data analysis, signal processing, and many other applications.

The box-and-whisker plot below represents some data set. What percentage of the data values are greater than 72?
Answer:
In a box-and-whisker plot, the box represents the middle 50% of the data, with the median value marked by a vertical line inside the box. The "whiskers" extend from the box to the minimum and maximum values in the data set that are not considered outliers. Outliers are marked by individual points outside the whiskers.
To determine the percentage of data values that are greater than a given value, we need to look at the box-and-whisker plot to see where that value falls in the data set. If the value is outside the box, we know that at least 50% of the data values are either greater or less than that value, depending on whether the value is greater or less than the median. If the value is inside the box, we know that exactly 50% of the data values are greater and 50% are less than that value.
In the case of the value 72, we cannot determine the percentage of data values that are greater than it without knowing where it falls in the box-and-whisker plot. If it falls outside the box, we only know that at least 50% of the data values are greater than it. If it falls inside the box, we only know that exactly 50% of the data values are greater than it.

If each section of the trim takes 1/2 can of paint, how many sections of trim can he paint? Show your answer as an inequality with symbols, in words, and with a number line. Make sure your solution makes sense for this situation.
Answer:
x ≤ 10Maximum number of trims that can be painted with 5 cans is 10See number line imageStep-by-step explanation:
There are 5 cans left over after painting the walls.
Let x represent the maximum number of trims that can be painted
Since each trim requires 1/2 a can, x trims will take x/2 cans
This cannot exceed 5 cans so we get the inequality:
x/2 ≤ 5
Multiplying by 2 both sides of inequality:
x ≤ 10
In words:
Maximum number of trims that can be painted with 5 cans is 10

What is 1.1 as a fraction?
We write the decimal as a fraction with the decimal value as the numerator and a power of 10 as the denominator, we get 1.1 as a fraction is 11/10.
To convert a decimal to a fraction, we write the decimal as a fraction with the decimal value as the numerator and a power of 10 as the denominator.
For 1.1, we can write it as:
1.1 = 11/10
Therefore, 1.1 as a fraction is 11/10.
Decimal numbers are a way to represent numbers that are not whole numbers or integers. A decimal number consists of two parts: a whole number part and a fractional part, separated by a decimal point. To convert a decimal number to a fraction, we need to write the decimal as a fraction with the decimal value as the numerator and a power of 10 as the denominator.
In the case of 1.1, we can write it as a fraction with a numerator of 11 (the decimal value) and a denominator of 10 (the power of 10 that corresponds to the first decimal place). We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 1 in this case. So the final fraction is 11/10.
Converting decimals to fractions is a useful skill in many areas of math, science, and engineering. It allows us to represent numbers in different ways and to perform calculations that involve fractions and decimals. Knowing how to convert between these two types of numbers can also help us understand the relationship between them and how they are used in real-world applications.

A: Yes. The input and output are both feasible.
B: No. Neither the input nor output is feasible.
C: No. The input is not feasible.
D: No. The output is not feasible.
Answer: A: Yes. The input and output are both feasible.
Step-by-step explanation:
To determine whether the solution (29.5, $212.50) makes sense for the function c(x), we need to evaluate whether the input and output are feasible and make sense in the context of the problem.
The input is given as 29.5, which represents the number of students. It is unclear from the information given whether a non-integer value for the number of students is feasible or not. However, if we assume that 29.5 students means 29 students and 1 child attending the carnival, then the input of 29.5 students is feasible.
The output is given as $212.50, which represents the amount of money spent at the carnival. It is reasonable to assume that a school group on a field trip would spend a certain amount of money at a carnival, and $212.50 is not an unreasonable amount to spend.
Therefore, based on the information given, we can conclude that the solution (29.5, $212.50) makes sense for the function c(x). So the answer is A: Yes. The input and output are both feasible.
if 12,00 people voted in the election how many were from 50 to 64 years old
The required population of the city is approximately 44,44.44.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Let's use algebra to solve for the population of the city.
Let P be the population of the city. We know that 27% of the population is from 50 to 64 years old.
The number of people from 50 to 64 years old is 27% of the whole population, which can be expressed as,
0.27P
We can set up an equation to relate the number of people from 50 to 64 years old to the number of eligible voters,
0.27P = x
where x is the number of people from 50 to 64 years old who voted.
We can solve for P by multiplying both sides of the equation by the reciprocal of 0.27,
P = x / 0.27
Substituting x with 1200,
P = 12,00 / 0.27 = 4444.44
Therefore, the population of the city is approximately 44,44.44.

The function f(t) = 930(0.9965) represents the change in a quantity over t hours. What does the constant 0.9965 reveal about the rate of change of the quantity?
The constant 0.9965 is the rate of change per hour. Specifically, it represents the factor by which the quantity changes every hour. In this case, the factor is less than 1, indicating that the quantity is decreasing over time.
To see how this rate of change works, consider an example:
If the initial quantity is 930, after one hour the quantity will be:
f(1) = 930(0.9965) ≈ 926.20
That is, the quantity has decreased by a factor of 0.9965, or about 0.35%.
After two hours, the quantity will be:
f(2) = 930(0.9965)^2 ≈ 922.42
That is, the quantity has decreased by a factor of 0.9965 twice, or about 0.70%.
So the constant 0.9965 reveals the rate of change of the quantity, which is a decrease of about 0.35% per hour.
