Which pair of variables would most likely have a negative correlation?
A. the time spent driving in a car and the number of miles driven

B. the height of a dog in inches and the number of ounces of food the dog eats per day

C. the number of sit-ups completed and the number of calories burned during a workout

D. the time spent reading a book and the number of pages remaining to be read in the book

Answers

Answer 1

Answer: D

Step-by-step explanation:

Answer 2

The pair of variables that will most likely have a negative correlation are D. the time spent reading a book and the number of pages remaining to be read in the book.

Negative CorrelationThis means that the variables involved move in the opposite direction from each other. Means that as one variable increases, the other decreases and vice versa.

If you spend a longer time reading a book, you would read more pages which would reduce the number of pages left to be read. The time taken to read the book is therefore negatively correlated with the number of pages left.

In conclusion, option D is correct.

calculate the length of the base of a parallelogram if the area is 135cm and it's height is 9cm

Answers

Answer:

15cm

Step-by-step explanation:

The formula to calculate the area of a parallelogram is base x height.

Since we know the height and area, we can write the equation:

135 = base x 9

Now we can just divide 9 from both sides to solve for base:

135/9=basex9/9

So we get:

Base = 135/9=15

The length of the base is 15cm.

The function g is defined below . g(x) = (x - 5)/(x ^ 2 - 36) Find all values of x that are NOT in the domain of g. If there is more than one value, separate them with commas.

Answers

Answer:

-6, 6

Step-by-step explanation:

So we have the rational function:

[tex]g(x)=\frac{x-5}{x^2-36}[/tex]

The domain of a rational function is all real numbers except for when x is a zero of the denominator.

Thus, to determine the domain restrictions, set the denominator to 0 and solve for x:

[tex]x^2-36=0[/tex]

Add 36 to both sides:

[tex]x^2=36[/tex]

Take the square root of both sides:

[tex]x=\pm 6[/tex]

So, the values that are not in the domain of g is: -6, 6.

And we're done!

What is the value of x & y?

Answers

Answer:

x = 16, y = 9

Step-by-step explanation:

The 2 triangles are similar by the AA postulate, thus the ratios of corresponding sides are equal, that is

[tex]\frac{x}{24}[/tex] = [tex]\frac{12}{18}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )

3x = 48 ( divide both sides by 3 )

x = 16

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

[tex]\frac{y}{6}[/tex] = [tex]\frac{18}{12}[/tex] = [tex]\frac{3}{2}[/tex] ( cross- multiply )

2y = 18 ( divide both sides by 2 )

y = 9

70% of 120 = 120x70/100

10% of 120 = 12
12 x 7 = 84
70% = 84

120 x 70 = 8400
8400 / 100 = 84

It’s either showing you that both sides of the equation equal to the same thing or that you can find 70% of 120 by using the steps on the right

The slope of the regression line is resistant to outliers.
In the equation of the least-squares regression line, ġ is an observed value when x is known.
The sum of the residuals is always close to zero.
The coefficient of determination measures how much of the variation in the y-values is explained by the regression line.
In the equation of the least-squares regression line, is a predicted value when x is known.

Answers

Answer:

1. The sum of the residuals is always close to zero.

2.The coefficient of determination measures how much of the variation in the y-values is explained by the regression line.

3. In the equation of the least-squares regression line, y hat is a predicted value when x is known

Step-by-step explanation:

The least square regression line is a line that makes distance from data points to the regression line to be as minimal as possible. This line is a best fit for the data points. Let's say we have a collection of numbers and a scatter plot, this line is a line that exists and best fits the data.

Therefore, the least square regression line minimizes sum of squared error to be close to zero. R² measures the extent to which variations in the value of y is explained by the regression line. In the equation of this line, y hat is a predicted value when x is known.

The least square regression line minimizes the sum of squared error such that the sum of the residual is zero or very close to 0. Hence, the true statements from the options given are :

Sum of residuals is always close to 0

The coefficient of determination measures how much of the variation in the y-values is explained by the regression line.

[tex]y_{hat} [/tex] is the predicted value when x is known.

The least square regression Line is used to create a Linear model in the form y = bx + c

The Coefficient of determination R² gives the proportion of the variation explained by the regression line.

The predicted value of y is obtained using the model of the Least Square Regression Line for a given value of x.

Outlier values often affects the performance and accuracy of the Least Square Regression Line.

A local library claims it has 2.73x103 books. If there are 42 people in the building, how many books per capita are there?

Answers

Answer:

63 books per capita in the library

Step-by-step explanation:

Given

[tex]Books = 2.73 * 10^3[/tex]

[tex]People = 43[/tex]

Required

Determine the book per capita

To do this, we simply divide the number of books by number of person;

[tex]Average = \frac{Books}{People}[/tex]

[tex]Average = \frac{2.73 * 10^3}{43}[/tex]

[tex]Average = \frac{2.73 * 1000}{43}[/tex]

[tex]Average = \frac{2730}{43}[/tex]

[tex]Average = 63.488372093[/tex]

[tex]Average = 63[/tex] (Approximated)

Hence;

There are 63 books per capita in the library
