Work Done = Time Taken x Rate of Work Work Rate = 1 / Time Taken Time taken = 1 / Rate of work If a piece of work is completed in x days, then the work completed in one day equals 1/x.

The fundamental concept of Time and Work is similar to that of all Arithmetic topics, namely the concept of Proportionality. When the amount of work done is constant, efficiency is inversely proportional to time.

Let x be the amount of hours Steve can spend typing a research paper.

Steve completes 1/x of a research paper per hour.

Alan completed 1/6 of the paper in an hour.

1/4 = amount of paper completed each hour by both of them

1/x + 1/6 = 1/4

Multiply by 12 on the LCD to get 12 + 2x = 3x x = 12 hours.

The measure of the average value of a random variable is called the expected value. So, the correct answer is B).

The expected value is a measure of central tendency that represents the average value of a random variable over an infinite number of trials. It is calculated by multiplying each possible outcome by its probability of occurring, and then summing up the products.

The expected value is a useful tool in probability theory and statistics, as it provides a way to predict the long-term behavior of a random variable. For example, in a game of chance, the expected value represents the average amount of money that a player can expect to win or lose over a large number of plays.

It is also used in decision-making under uncertainty to compare different alternatives based on their expected outcomes. So, the correct option is B).

Answer:

Ok, what's your statistic problem?

Step-by-step explanation:

The equation of the perpendicular line passing through the point (-3,3) in "slope-intercept" form is y = (-1/3)x + 2.

In the graph, We observe that, the given line passes through the point (1,2) and (-1,-4);

First we find the slope of the given line that passes through (1,2) and (-1,-4),

⇒ Slope = (-4 -2)/(-1-1) = -6/-2 = 3,

⇒ slope of given line is 3,

we want to find the equation of a line which is perpendicular to this line, and we know that the slope of the new line will be the negative reciprocal of 3,

So, slope of perpendicular line = -1/3,

Now we use point-slope form of equation of a line to find equation of the new line.

The equation in "point-slope" form is denoted as : y - y₁ = m(x - x₁),

where m = slope and (x₁, y₁) is = point on line.

Substituting the values of "slope = -1/3" and point (-3, 3),

We get,

⇒ y - 3 = (-1/3)(x - (-3)),

⇒ y - 3 = (-1/3)x - 1

⇒ y = (-1/3)x + 2

Therefore, the required equation of the perpendicular line in slope-intercept form is y = (-1/3)x + 2.

Their hourly wage in 9 more years is $23.60 per hour.

To find the hourly wage in 9 more years, we can use the formula for exponential growth:

A = \(P * (1 + r)^t\)

Where:

To find the annual growth rate, we can use the formula:

r = \((A/P)^(^1^/^t^)\) - 1

Substituting the given values, we get:

r = \((\$16.09 / \$6.90)^(^1^/^1^1^)\) - 1

r = 0.0883 or 8.83%

Now we can use this growth rate to find the hourly wage in 9 more years:

A = $6.90 * \((1 + 0.0883)^9\)

A = $23.60 (rounded to the nearest cent)

Therefore, the hourly wage of the automobile plant workers in 9 more years, if their wages continue to grow exponentially at the same rate, would be $23.60 per hour.

When x is correlated with y, it means that there exists a relationship between the two variables, where a change in one variable (x) is associated with a change in the other variable (y).

This relationship can be either positive or negative.

In a positive correlation, as the value of x increases, the value of y also increases, and as the value of x decreases, the value of y decreases as well. This indicates that both variables move in the same direction. On the other hand, in a negative correlation, as the value of x increases, the value of y decreases, and as the value of x decreases, the value of y increases. This shows that the variables move in opposite directions.

It is essential to note that correlation does not imply causation. Just because two variables are correlated does not mean that one variable causes the other to change. There could be other factors or variables that influence the observed relationship between x and y. Additionally, the strength of the correlation can vary, with values close to 1 or -1 representing a strong relationship and values close to 0 representing a weak relationship or no relationship at all.

In conclusion, when x is correlated with y, it means that there is a relationship between the two variables that can be either positive or negative, but this does not necessarily imply causation. The strength of the relationship can also vary, depending on the correlation coefficient value.

Step-by-step explanation:

If a $52 item is marked up by 10%, its new price will be:

$52 + 10% of $52 = $52 + $5.20 = $57.20

Then, if this new price is marked down by 10%, the final price will be:

$57.20 - 10% of $57.20 = $57.20 - $5.72 = $51.48

Therefore, the final price of the item after the markup and markdown is $51.48.

A cumulative relative frequency distribution shows option (A) the proportion of data items with values less than the upper limit of each class

A cumulative relative frequency distribution shows the proportion of data items with values less than or equal to the upper limit of each class. It provides a cumulative summary of the data distribution by adding up the frequencies or proportions of all preceding classes.

To construct a cumulative relative frequency distribution, you start with the lowest class and calculate the relative frequency (proportion) of data items in that class. Then, for each subsequent class, you add the relative frequency of that class to the cumulative relative frequency from the previous class. This cumulative value represents the proportion of data items with values less than or equal to the upper limit of the current class.

In essence, a cumulative relative frequency distribution allows you to track the accumulation of data values as you move through the classes, giving insights into the overall distribution and the proportion of data items falling below specific values.

the height of the triangle formed by the diagonal and base of the TV screen.

The height of the TV is approximately 15.6 inches.

(26 inches / √2) = 18.8 inches

(18.8 inches * √2) = 26 inches

Height = (26 inches / 18.8 inches) * 18.8 inches

Height = 15.6 inches

Step 1: Calculate the hypotenuse of the triangle formed by the diagonal and base of the TV screen.

Hypotenuse = diagonal / √2

Hypotenuse = 26 inches / √2

Hypotenuse = 18.8 inches

Step 2: Calculate the diagonal of the triangle formed by the hypotenuse and base of the TV screen.

Diagonal = hypotenuse * √2

Diagonal = 18.8 inches * √2

Diagonal = 26 inches

Answer:

the answer is C

Step-by-step explanation:

We can use the F-test to determine the overall significance of the relationship between the number of books students referred to and the number of lectures they attended, and their final grade on the course.

To conduct the F-test, we need to calculate the F-statistic, which is the ratio of the variance between the groups (books and lectures) to the variance within the groups.

Using the data given, we calculate the F-statistic as F = 7.35. This value is compared to the critical value for F at the 0.05 level of significance, which is 3.86. Since the F-statistic is greater than the critical value, we can conclude that there is a significant relationship between the number of books students referred to, the number of lectures they attended, and their final grade on the course.

A geometric series is a collection of terms in mathematics that have an unlimited number and a fixed ratio between each term. Because each succeeding term may be produced by doubling the previous term by half, for instance, the series

1/2+1/4+1/8+1/16+ ..........is geometric, because each successive term can be obtained by multiplying the previous term by 1/2.

The geometric series had an important role in the early development of calculus, is used throughout mathematics, and can serve as an introduction to frequently used mathematical tools such as the Taylor series, the complex Fourier series, and the matrix exponential.

Each term in a geometric series is the geometric mean of its two adjacent terms, as indicated by the name.
