In this investigation, the dependent variable is the number of fish in the stream and the independent variable is the amount of pollution.

Variables are symbols or names that are used to represent values in a mathematical or scientific investigation. They allow us to describe and analyze patterns and relationships in data.

There are two main types of variables:

1. Independent variables are variables that are manipulated or controlled in an experiment to determine their effect on the dependent variable. The independent variable is also referred to as the predictor variable or the explanatory variable.

2. Dependent variables are variables that are being measured in an experiment and are dependent on the independent variable. The dependent variable is also referred to as the response variable or the outcome variable. It is the variable that is being affected by the independent variable.

The dependent variable is dependent on the independent variable, as changes in the amount of pollution are expected to affect the number of fish in the stream. The goal of the investigation is to determine the relationship between the two variables and see how changes in the amount of pollution affect the number of fish in the stream.

The least positive integer $n$ such that no matter how $10^n$ is expressed as the product of two positive integers, at least one of these two integers contains the digit 0, is 7.

Latex formula for equation.

f(x) = x^2 + 2x + 1

Let's consider the factorization of $10^n$ for increasing values of $n$.

For $n = 1$, $10^1 = 10$ which contains the digit 0.

For $n = 2$, $10^2 = 100$ which contains the digit 0.

For $n = 3$, $10^3 = 1000$ which contains the digit 0.

For $n = 4$, $10^4 = 10,000$ which contains the digit 0.

For $n = 5$, $10^5 = 100,000$ which contains the digit 0.

For $n = 6$, $10^6 = 1,000,000$ which contains the digit 0.

For $n = 7$, $10^7 = 10,000,000$ which contains no digit 0.

Therefore, the least positive integer $n$ is 7.

The cost of the tie was 127.50 - (90 + 7.50) = 30.

Joe paid 90 for his new shoes, 30 for the tie, and 7.50 for the shirt.

The total cost of the shoes, tie, and shirt was 127.50.

The cost of the shoes was 3 times the cost of the tie and shirt together. Therefore, the cost of the shoes was 3 x (30 + 7.50) = 90.

The cost of the shirt was a quarter the cost of the shoes and tie together. Therefore, the cost of the shirt was (90 + 30) / 4 = 7.50.

The cost of the tie was the remaining amount after subtracting the cost of the shoes and shirt from the total cost. Therefore, the cost of the tie was 127.50 - (90 + 7.50) = 30.

If each of the plant's cans was filled to 12 ounces, the standard deviation of the sample of 10 cans would give us an idea of how much the weights of the cans deviate from the average weight of 12 ounces.

The calculation of the standard deviation requires knowledge of the mean and variance of the sample. To find the variance, we would need to subtract the mean from each of the observed weights, square the differences, and find the average of the squared differences. Finally, to find the standard deviation, we would take the square root of the variance.

It's worth noting that in practice, finding the standard deviation of a sample can be a complex and time-consuming process, especially when dealing with large sample sizes. However, it is a valuable metric that provides important information about the distribution and spread of the data.

The least appropriate measure of central tendency for a data set that contains outliers is the mean. This is because the mean is calculated by taking the sum of all the values in the data set and dividing it by the number of values. This means that the mean is heavily influenced by outliers, as they are included in the calculation.

The median, 2nd quartile, and 50th percentile are all more appropriate measures of central tendency for a data set that contains outliers, as they are not affected by the presence of outliers. The median is calculated by taking the middle value of the data set, the 2nd quartile is calculated by taking the median of the upper half of the data set, and the 50th percentile is calculated by taking the value at the 50th percentile of the data set.

Sophia would pay £2.45 less if she bought her 2 meals at Restaurant B

Cost is the value of money that has been used up to produce something or deliver a service, and hence is not available for use anymore.

First, let's find the total cost of 2 meals at Restaurant A. The first meal costs £16.50, and the second meal is half-price, so it costs £16.50 / 2 = £8.25.

The total cost of 2 meals at Restaurant A is £16.50 + £8.25 = £24.75.

Next, let's find the total cost of 2 meals at Restaurant B. The meals each cost £16, so the total cost of 2 meals is £16 * 2 = £32.

After applying a 15% discount, the total cost of 2 meals is £32 * (1 - 0.15) = £27.20.

Finally, let's find the difference between the prices Sophia would pay at the two restaurants:

£24.75 - £27.20 = -£2.45

So, Sophia would pay £2.45 less if she bought her 2 meals at Restaurant B

A square is any rectangle with four similar sides: TRUE

Rhombuses are all quadrilaterals: FALSE

A parallelogram exists in every square: FALSE

A square exists in every quadrilateral: TRUE

A quadrilateral in geometry is a four-sided polygon with four sides and four corners (vertices).

The Latin words quadri, a variation of four, and latus, meaning "side," are the source of the name.

In reference to other polygons, it is also known as a tetragon, from the Greek "tetra" for "four" and "gon" for "corner" or "angle" (e.g. pentagon).

The square is the only quadrilateral that is regular (all sides and angles are equal).

Therefore, every other quadrilateral is irregular.

A square is any rectangle with four similar sides.

Not all rhombuses are quadrilaterals.

The difficulty of range as a measure of variability that is overcome by interquartile range is option b that is The range is influenced too much by extreme values.

The variance is the mean squared difference between each data point and the mean-centered distribution. A statistical assessment of the dispersion of values in a data collection is referred to as variance. Variance explicitly assesses how distant each number in the set is from the mean (average), and consequently from every other number in the set. Variance is a measure of how data points differ from the mean, whereas standard deviation is a measure of statistical data distribution. The primary distinction between the two is that standard deviation is expressed in the same units as the mean of the data, whereas variance is expressed in squared units.

Answer:155.56%.

Step-by-step explanation:To find the percentage increase, we need to calculate the difference between the two prices and divide it by the original price, then multiply by 100 to express the answer as a percentage.

Percentage increase = (New price - Original price) / Original price * 100

Percentage increase = (459 - 180) / 180 * 100

Percentage increase = 279 / 180 * 100

Percentage increase = 155.56%

So the price of the item increased by 155.56%.

Decrease in population = 5%

Now,

The population after x years can be written as an equation.

y = 300,000 x [tex]0.95^x[/tex]

For x = 6,

y = 300,000 x [tex]0.95^6[/tex]

y = 300,000 x 0.7351

y = 220527.568
