Sarah's company started out with a $350 value and is currently changing at a rate of $100 annually.

The annual fee is expressed as an equation in slope-intercept form:

y = 100x + 350.

y = mx + b, where m is the line's slope and b is its y-intercept, is the formula for a straight line.

Given details:

The table displays the prices that Sarah charged each client during the course of her business's first two years:

Year                            Annual Dog-walking Fee

2010                            $350

2014                            $750

A.

Sarah has so increased the cost by $400 over the past four years.

For Sarah's company, its rate of change called slope will be,

m = 750 - 350 / 4

m = 100

Therefore, Sarah is raising the cost by $100 yearly.

Due to the payment she received for the first year, the calculated values of a business is $350.

B. Define x as the period of time that has passed since she began her business in 2010.

Consequently, the annual fee equation can be expressed in slope-intercept form as,

y = mx + c

where y stands for the cost she must pay after x years.

Her company's baseline value is therefore $350, and its rate of change is $100 annually.

The annual fee is expressed as an equation in slope-intercept form.: y = 100x + 350.

Volume of a Triangular Prism Formula

Is used To Find the 3-D space/ volume occupied by a triangular prism.

V=1/4h√((c+a−b)(a+b−c))× √((a+b+c)(b+c−a))

side length a = 4

side length b = 5

side length c = 3

prism height h = 8

V=1/4h√((c+a−b)(a+b−c))× √((a+b+c)(b+c−a))

V=1/4(8)√((3+4−5)(4+5−3))× √((4+5+c3)(5+3−4))

V= 48cm³

The maximum volume of the box in terms of the height h is (30 - h/2)^2 x h, and the height that allows us to have the maximum volume is 40 inches

To answer your question, let's first understand that the volume of a box is given by the formula V = L x W x H, where L is the length, W is the width and H is the height. Since we are assuming the height is fixed, we can rewrite this formula as V = L x W x h.

Now, we know that the length plus width plus height of the box cannot exceed 60 inches. Therefore, we have the equation L + W + h = 60, which we can solve for L or W in terms of h. Let's solve for L: L = 60 - W - h.

Substituting this value of L into the formula for volume, we get V = (60 - W - h) x W x h. We can simplify this equation by expanding the brackets and collecting like terms to get V = -W^2h + 60Wh - h^2.

To find the maximum volume, we need to find the value of W that maximizes this equation. We can do this by differentiating the equation with respect to W and setting the derivative equal to zero. After some calculations, we get W = 30 - h/2.

Substituting this value of W back into the equation for volume, we get V = (30 - h/2)^2 x h. To find the height that gives us the maximum volume, we can differentiate this equation with respect to h and set the derivative equal to zero. After some calculations, we get h = 40 inches.

Therefore, the maximum volume of the box in terms of the height h is (30 - h/2)^2 x h, and the height that allows us to have the maximum volume is 40 inches.

The cumulative frequency and relative cumulative frequency for students who earned a score of 20 or lower on the quiz is 29; 58%. (option d)

Cumulative frequency refers to the running total of frequencies, or the sum of frequencies up to a certain point. In this case, the cumulative frequency is the number of students who scored 20 or lower on the quiz.

Relative cumulative frequency, on the other hand, expresses the cumulative frequency as a percentage of the total number of students in the sample. To find the relative cumulative frequency, we divide the cumulative frequency by the total number of students and multiply by 100.

Therefore, for students who scored 20 or lower on the quiz, the cumulative frequency is 29 and the relative cumulative frequency is 58% (29/50 * 100).

The scale that Pedro used for the drawing is: 17:600.

Step-by-step explanation:

A scale of a drawing is expressed as: Drawing length:actual length.

Since you know that the pool is 119 centimeters long in the drawing and 42 meters long in real life, first you have to find  the cm in 42 meter taking into account that 1 meter is equal to 100 cm:

1 m     →    100 cm

42 m   →          x

x=(42*100)/1

x=4200 cm

Now, the scale would be:

119:4200

Finally, you need to simplify and you can do it by dividing each number by 7:

17:600

According to this, the answer is that the scale that Pedro used for the drawing is: 17:600.

The accuracy of any estimate of the mean high temperature will depend on the quality and quantity of data available, as well as the methods used to analyze and interpret this data.

To estimate the mean high temperature with a value of 797687, we need to first understand what this value represents. Assuming that this value represents the high temperature for a certain area or region, we can use statistical methods to estimate the mean high temperature for this area.

One way to estimate the mean high temperature is to take a sample of high temperature data for this area, and then calculate the average of this sample. This sample should be large enough to provide a representative estimate of the population mean, but not so large as to be impractical or expensive.

Another way to estimate the mean high temperature is to use historical data or climate models to predict future high temperatures. This method requires knowledge of past trends and patterns in temperature data, as well as an understanding of the factors that influence high temperatures in this area.

It is important to use sound statistical techniques and to be aware of potential sources of bias or error when making any estimates of this nature.

The area of the computer monitor display is approximately 0.103 square meters, with three significant figures.

The area of the monitor display in square meters is found by converting the measurements from inches to meters and then calculate the area.

The conversion factor from inches to meters is 0.0254 meters per inch.

Width in meters = 14.60 inches * 0.0254 meters/inch

Height in meters = 10.95 inches * 0.0254 meters/inch

Area = Width in meters * Height in meters

We calculate the area:

Width in meters = 14.60 inches * 0.0254 meters/inch = 0.37084 meters

Height in meters = 10.95 inches * 0.0254 meters/inch = 0.27813 meters

Area = 0.37084 meters * 0.27813 meters = 0.1030881672 square meters

Now, we determine the number of significant figures.

The measurements provided have four significant figures (14.60 and 10.95). However, in the final answer, we should retain the least number of significant figures from the original measurements, which is three (10.95). Therefore, the answer should have three significant figures.

Thus, the area of the monitor display in square meters is approximately 0.103 square meters, with three significant figures.

The range of feasible values for the multiple coefficients of correlation is from -1 to 1.

The multiple coefficients of correlation, also known as the multiple R or R-squared, measures the strength and direction of the linear relationship between a dependent variable and multiple independent variables in a regression model. It quantifies the proportion of the variance in the dependent variable that is explained by the independent variables.

The multiple coefficients of correlation can take values between -1 and 1.

A value of 1 indicates a perfect positive linear relationship, meaning that all the data points fall exactly on a straight line with a positive slope.

A value of -1 indicates a perfect negative linear relationship, meaning that all the data points fall exactly on a straight line with a negative slope.

A value of 0 indicates no linear relationship between the variables.

Values between -1 and 1 indicate varying degrees of linear relationship, with values closer to -1 or 1 indicating a stronger relationship. The sign of the multiple coefficients of correlation indicates the direction of the relationship (positive or negative), while the absolute value represents the strength.

The range from -1 to 1 ensures that the multiple coefficients of correlation remain bounded and interpretable as a measure of linear relationship strength.
