Ms. Hartman buys 4 pounds of potatoes for $12.76. How many pounds of potatoes could she get for $44.66?

Answer:

The lines are perpendicular. When you graph these line they intersect one another which is perpendicular.

Step-by-step explanation:

When you rearrange the equation x-3y=15 you get y=1/3x-5

The derivative of y = ln(x) is y' = 1/x. Taking the second derivative, we have y'' = -1/x^2.

To find the derivative of y = ln(x), we can use the basic differentiation rule for logarithmic functions. The derivative of ln(x) with respect to x is 1/x. Therefore, the first derivative of y = ln(x) is y' = 1/x.

To find the second derivative, we need to differentiate y' = 1/x with respect to x. Applying the differentiation rule for 1/x, we obtain y'' = -1/x^2.

The second derivative y'' = -1/x^2 indicates the rate of change of the slope of the original function y = ln(x). It tells us how quickly the slope of the function is changing at each point.

Since the derivative of y' is negative, it means that the slope of y' is decreasing as x increases. In other words, as x gets larger, the rate of change of the slope becomes smaller and smaller.

In summary, the derivative of y = ln(x) is y' = 1/x, and the second derivative is y'' = -1/x^2.

These derivatives help us understand the behavior of the logarithmic function and provide information about its rate of change and concavity.

Answer:

360 nickles

Step-by-step explanation:

you had the equation in front of you so just dived those numbers and 360 should be your answers and to check it multiply 360 by 0.05

Just use a calculator.

First substitute in the numbers and make sure to use ( ) when plugging in negative values. For example, the first one says n=4, you can substitute n from the expression to 4. So n^2 + 3n + 8 will turn into 4^2 + 3(4) + 8 which is 16 + 12 + 8 = 36. You can do this with the other questions.

In mathematics, the point below which a specified percentage of the observations fall is commonly referred to as the percentile.

A percentile is a measure that indicates the relative position of a particular value within a dataset.

For example, if a value is at the 80th percentile, it means that 80% of the observations in the dataset are below that value, and only 20% of the observations are above it.

Percentiles are often used to analyze and understand the distribution of data, especially in fields such as statistics, probability, and data analysis. They provide insights into how individual data points compare to the overall dataset and help identify outliers or extreme values.

A percentile is a statistical measure that indicates the relative standing of a particular value within a dataset. It represents the point below which a specified percentage of the observations or data points fall. Percentiles are primarily used to understand the distribution of data and analyze how individual values compare to the overall dataset.

To calculate a percentile, the dataset is arranged in ascending order, from the smallest value to the largest value. The position of a specific percentile is then determined based on the percentage of data points below it. For example, the 75th percentile represents the value below which 75% of the data points fall.

Percentiles are commonly used in various fields, including statistics, probability, and data analysis. They provide valuable insights into the spread, variability, and distribution of data. Here are a few key points to consider:

1. Median: The median is the 50th percentile, representing the value that divides the dataset into two equal halves. It is a measure of central tendency and provides information about the middle point of the distribution.

2. Quartiles: Quartiles divide the dataset into four equal parts. The first quartile, or the 25th percentile (Q1), represents the value below which 25% of the data points fall. The third quartile, or the 75th percentile (Q3), represents the value below which 75% of the data points fall. The difference between Q3 and Q1 is known as the interquartile range (IQR) and provides insights into the spread of the middle 50% of the data.

3. Percentile Ranks: Percentile ranks indicate the percentage of data points that are below a specific value. For example, if a student scores in the 80th percentile on a standardized test, it means they performed better than 80% of the test-takers.

4. Outliers: Percentiles can be useful in identifying outliers, which are data points that significantly deviate from the rest of the dataset. Extremely high or low percentiles may indicate unusual or extreme values that warrant further investigation.

5. Normal Distribution: In a normal distribution, the 50th percentile (median) coincides with the mean and mode, and specific percentiles have known standard deviations from the mean (e.g., the 68-95-99.7 rule).

Percentiles are versatile tools for summarizing and analyzing data, providing valuable insights into the distribution and relative positions of individual values. They enable comparisons and help make informed decisions based on the characteristics of a dataset.

Step-by-step explanation:

5/8=0.625

0.42=0.42^2

Answer:

(x+5) is not a factor of f(x)

Step-by-step explanation:

Step 1 : we solve the equation x +5 = 0

x + 5 = 0 then x = -5

Step 2: we plug in -5 into f(x)

If we get zero then x+5 is a factor of f(x)

If we get a number other than zero then x+5 is not a factor of f(x)

Calculation:

f(-5) =  (-5)³ − 4(-5)² + 3(-5) + 7 = - 233

Since we got -233 and not 0

Therefore ,(x+5) is not a factor of f(x)

Answer:

(x + 5) is not a factor of f(x) = x^3 - 4x^2 + 3x + 7

Step-by-step explanation:

To see if (x + 5) is a factor, you can use either synthetic division or long division.

I'll be using synthetic division to divide f(x) by (x + 5):

-5 | 1 -4 3 7

| -5 45 -240

---------------------

1 -9 48 -233

The remainder is -233, which means that (x + 5) is not a factor of f(x) since there is a remainder.

Therefore, (x + 5) is not a factor of f(x) = x^3 - 4x^2 + 3x + 7.

The complement of the empty set is the set of all possible elements in the universal set U, which is the English alphabet in this context.

The universal set U is defined as the set of all possible elements or values under consideration for a given context. On the other hand, the complement of a set A is defined as the set of all elements that are not in A but are in U.

The complement of the empty set is defined as the set of all elements in U since the empty set is a subset of every set.

Therefore, the complement of the empty set in this context would be the entire set of all letters in the English alphabet.

This is because the empty set contains no elements, and therefore, its complement would be the set of all possible elements in U, which in this case is the English alphabet.

Tan(3/4 - \(\pi\) ) = 1, which is the ratio of a right triangle with a 45° angle's opposite side to its adjacent side. This is different from value of \(tan(3\pi /4)\), which is -1, it corresponds to a different angle.

The tangent of the angle 3/4 (or 135 degrees) is equal to -1 because \(tan(3/4)\)has a value of -1. The ratio of the opposite side to the adjacent side can be calculated by drawing a right triangle with an angle of 135 degrees.

To obtain the value of\(tan(3\pi /4 - \pi )\), we first need to simplify the phrase \(3\pi /4 - \pi\), which gives us\(\pi /4\) (or 45 degrees). Therefore, we need to find the tangent of the angle 45 degrees.

The ratio of the opposite side to the adjacent side of a right triangle with a 45-degree angle has the value of \(tan(45)\), which is equal to 1.

So, \(tan(3\pi /4 – \pi ) = tan(\pi /4) = 1.\)

In summary, the value of\(tan(3\pi/4 - \pi)\)) is equal to 1, which is the ratio of the opposite side to the adjacent side of a right triangle with an angle of 45 degrees. This is distinct from the value of \(tan(3\pi /4)\), which is -1, as it corresponds to a different angle.

Answer:

Gusion = 2years

Lesley= 40years

Step-by-step explanation:

Let Guison age be x

Let Lesley age be y

If the sum of the ages of Gusion and Lesley is 42, then;

x+ y =42 ... 1

Four years ago

Guison age = x - 4

Lesley age = y - 4

If four years ago, Gusion was twice as old as Lesley, then;

x - 4 = 2(y-4)

x - 4 = 2y - 9

x - 2y = -9+4

x - 2y = -5 .... 2

Substract 1 from 2;

y + 2y = 1+5

3y = 6

y = 2

From 1;

x = 42 - y

x = 42-2

x = 40

Hence present age pf Guison is 2 years

Present age of Lesley is 40 years

Find the minimum proportion of observations in the population that are in the range 8,800 to 9,200 is 0.75,.

Note that based on the metrics given:

µ = 8,000

σ = 100.

Hence, according to the Chebyshev’s Theorem,

1. At least 3/4 (75%) of the data fall within two standard deviations of the mean, i.e. in the interval with endpoints 2 for populations.

2. At least 8/9 (88.9%) of the data fall within three standard deviations of the mean, i.e. in the interval with endpoints 3 for populations.

3. at least 1/k2 of the data are within k standard deviations of the mean, i.e. in the interval with endpoints k for populations, where k is any positive whole integer higher than 1.

Hence because the shape of the distribution is not known, using Chebyshev's theorem,

μ-2σ = 8000-2*100 = 7800

μ+2σ = 9000+2*100 = 9200

Hence 75% value will lie between 7,800 and 9,200

P(t1 < t-1 < t²) is the probability that t1 is less than t raised to the power of -1, which is less than t squared.

To calculate the probability P(t1 < t-1 < t²), you need to determine the range of values for t that satisfy this inequality. Start by isolating t:

1. t1 < t-1 → t1 + 1 < t (by adding 1 to both sides)
2. t-1 < t² → 1/t < t (by rewriting t-1 as 1/t)

Now, find the range of t values that satisfy both inequalities. Graph these inequalities on a number line, and identify the intersection of the two ranges. The probability P(t1 < t-1 < t²) will be the proportion of this intersection relative to the total possible range of values for t.

The homeowner has 160 feet of fencing to use for enclosing their backyard, with one side of the fence being the back of the house.

To calculate the remaining sides of the fence, we need to determine the total perimeter of the fenced area and then subtract the length of the house side. Let's assume the length of the house side is "L" feet.

The perimeter of a rectangle is given by the equation:

Perimeter = 2 * (Length + Width)

Since we have the back of the house as one side, the remaining sides would form a rectangle. Let's assume the width of the rectangle is "W" feet.

So the equation becomes:

Perimeter = 2 * (L + W)

Given that the total perimeter is 160 feet, we can write:

160 = 2 * (L + W)

Dividing both sides of the equation by 2 gives us:

80 = L + W

Now, since the homeowner wants to use the back of the house as one side, the length of the house side, "L," would be the length of the house. Therefore, we can substitute "L" with the length of the house.

To determine how long it will take Mary Corens to repay her student loan, we can divide the total loan amount of $15,000 by the annual repayment amount of $1,800. The result will give us the number of years it will take her to repay the loan.

it will take Mary approximately 8 years to repay the loan.

By dividing the total loan amount of $15,000 by the annual repayment amount of $1,800, we can calculate the number of years needed to repay the loan.

Loan amount: $15,000

Annual repayment: $1,800

Number of years = Loan amount / Annual repayment

Number of years = $15,000 / $1,800

Number of years ≈ 8.33

Since we are asked to round the answer to the nearest whole number, Mary will take approximately 8 years to repay the loan.

It's important to note that this calculation assumes a constant annual repayment amount of $1,800 throughout the entire loan repayment period. In reality, factors such as interest accrual and varying repayment schedules may affect the actual time it takes to fully repay the loan. Additionally, any changes to the annual repayment amount would also impact the duration of the loan repayment.

An estimate for the number of batters in the league who will have a batting average of at least 0.400 is approximately 0.7.

We can use the standard normal distribution to find the expected number of batters with an average of at least 0.400.

First, we calculate the z-score for a batting average of 0.400:

z = (0.400 - 0.260) / 0.05 = 2.8

Using a standard normal distribution table or calculator, we can find the probability of getting a z-score of 2.8 or higher:

P(Z ≥ 2.8) ≈ 0.0026

This means that the probability of a batter having an average of at least 0.400 is about 0.0026.

To find the expected number of batters with an average of at least 0.400, we can multiply this probability by the total number of batters:

Expected number of batters = 0.0026 * 270 ≈ 0.7

Therefore, we can expect that about 0.7 batters in the league will have a batting average of at least 0.400.
