The decimal fraction 3.003 can be expressed as the sum of fractions 3,003/1,000.

To express the decimal fraction 3,003 as a sum of fractions with a denominator that is a power of 10, we first need to determine the number of decimal places in the fraction. In this case, there are three decimal places, so we can write:

3,003 = 3 + 0.0 0 3

To express 0.003 as a fraction, we can write it as:

0.003 = 3/1000

So, we can write:

3,003 = 3 + 3/1000

To express this as a fraction with a denominator that is a power of 10, we can write:

3,003 = 3,000/1,000 + 3/1,000

Simplifying this expression, we get:

3,003 = 3,000/1,000 + 3/1,000 = (3,000 + 3)/1,000 = 3,003/1,000

Therefore, the decimal fraction 3,003 can be expressed as a sum of fractions with a denominator that is a power of 10 as 3,003/1,000.

The mean is 35 minutes and the median is 34 minutes.

let's first calculate the mean, median, and mode for Sarah's exercise times: 34, 30, 45, 30, 40, 38, and 28 minutes.

Step 1: Calculate the mean
Add up all the values and divide by the total number of values:
(34 + 30 + 45 + 30 + 40 + 38 + 28) / 7 = 245 / 7 = 35 minutes (rounded)

Step 2: Calculate the median
Arrange the values in ascending order: 28, 30, 30, 34, 38, 40, 45
There are 7 values, so the median is the middle value: 34 minutes

Step 3: Calculate the mode
Determine the value(s) that occur most often: 30 minutes (occurs twice)

Now, should Sarah use the mean or the median to show she exercises for large amounts of time each day? The mean is 35 minutes and the median is 34 minutes. Both values are close and represent the central tendency of the data. However, since the mean is slightly higher than the median, Sarah should use the mean (35 minutes) to show she exercises for a larger amount of time each day.

Step-by-step explanation:

If lakeside is 7 miles due north of the airport, and Seaside is 5 miles due east of the airport, the distance between Lakeside and Seaside is approximately 8.6 miles.

To find the distance between Lakeside and Seaside, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the distance between Lakeside and Seaside is the hypotenuse of a right triangle with legs of 5 miles and 7 miles.

To apply the Pythagorean theorem, we can square the lengths of the legs and then take the square root of their sum:

distance = √(5² + 7²)

distance = √(25 + 49)

distance = √74

Jade rides 1.275 miles before stopping for a water break.

To solve this problem, we need to multiply the length of the trail by the fraction representing the portion of the trail that Jade rides.

First, we need to convert the mixed number 5 1/10 into an improper fraction. We do this by multiplying the whole number (5) by the denominator of the fraction (10) and adding the numerator (1). This gives us 51/10.

Next, we multiply 51/10 by 1/4 to find the fraction of the trail that Jade rides before stopping for a water break:

(51/10) x (1/4) = 51/40

To convert this fraction into a decimal, we divide the numerator by the denominator:

51 ÷ 40 = 1.275

Therefore, Jade rides 1.275 miles before stopping for a water break.

In summary, to find how many miles Jade rides before stopping, we convert the mixed number representing the length of the trail into an improper fraction, multiply it by the fraction representing the portion of the trail that Jade rides, and then convert the resulting fraction into a decimal to get our answer.

The possible propagated error in computing the area of the square is between 19/32 and 21/32 square inches.

(a) Let A be the area of the square tile. The differential of A with respect to the side length x is dA/dx = 2x.

dA ≈ (dA/dx)dx

At the lower end of the possible range for x, we have:

x = 9 31/32 inches

dx = 1/32 inch

dA = (2x)(dx) = (2(9 31/32))(1/32) = 19/32 square inches

At the upper end of the possible range for x, we have:

x = 10 1/32 inches

dx = 1/32 inch

dA = (2x)(dx) = (2(10 1/32))(1/32) = 21/32 square inches

Therefore, the possible propagated error in computing the area of the square is between 19/32 and 21/32 square inches.

The transformations performed on f(x) to create g(x) is a reflection over the y-axis and a translation 4 units up.

An equation for g(x) in terms of f(x) is g(x) = f(-x) + 4.

In Mathematics and Geometry, a reflection over or across the y-axis or line x = 0 is represented and modeled by this transformation rule (x, y) → (-x, y).

By applying a reflection over the y-axis to coordinate A of the image ABCD, we have the following:

(x, y)                               →              (-x, y)

Coordinate = (-1, 1/10)   →  Coordinate A' = (-(-1), 1/10) = (1, 1/10).

To find the face value (p) of the note, we need to use the formula for simple interest:

I = P * r * t

where:

I = interest

P = principal or face value

r = interest rate per year

t = time in years

Since the note has a 6% interest rate and a 150-day term, we need to convert the time to years:

t = 150 / 365

t = 0.41096 years

Now we can solve for the face value:

I = P * r * t

2550 = P * 0.06 * 0.41096

2550 = 0.0246576P

P = 2550 / 0.0246576

P = 103364.99

So the face value (p) of the note is $103,364.99.

To find the interest (i), we can subtract the face value from the balloon payment:

i = 2550 - 103364.99

i = -100814.99

The negative interest result may seem strange, but it's because the balloon payment was higher than the face value of the note. In other words, Averi paid more than the note was worth in order to fully pay off the principal and interest.

The sample distribution of the mean, denoted as X, is the distribution of all possible sample means of a certain sample size taken from a population. In this case, we have a population of couples in conflict, and we have a sample size of 37. The mean length of time couples in conflict listen to each other is known to be 8 seconds with a standard deviation of 5 seconds.

Since we have a large enough sample size (n=37), we can assume that the sample mean follows a normal distribution according to the Central Limit Theorem. The Central Limit Theorem states that the sample means from a large enough sample size will be approximately normally distributed regardless of the population distribution, given that the samples are independent and randomly selected.

Thus, the sample distribution of X can be represented by a normal distribution with a mean of 8 seconds (same as the population mean) and a standard deviation of 5 seconds divided by the square root of the sample size (n=37), which is approximately 0.820 seconds:

To find the z-score associated with the 96th percentile, we need to use the standard normal distribution, which has a mean of 0 and a standard deviation of 1. We can convert the given distribution to a standard normal distribution by using the formula:

z = (x - μ) / σ

where z is the z-score, x is the value we want to convert, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

In this case, we want to find the z-score associated with the 96th percentile. The 96th percentile is the value below which 96% of the observations fall. We can find this value by using a standard normal table or a calculator. Using a calculator, we get:

This means that the z-score associated with the 96th percentile is 1.75.

To find the height of a 16-year-old boy in the 96th percentile, we can use the formula:

x = μ + z * σ

where x is the value we want to find, μ is the mean of the distribution, σ is the standard deviation of the distribution, and z is the z-score we just found.
