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.

A-9/a / 1-3/a=
Answers
Answer:
the answer is a+9/2
Step-by-step explanation:
a-9/a/1-3/a
=a-9/a/-2/a
=a+9/a/2/a.
( dividing two negatives is equal to positive)
=a+9/a*a/2
doing reciprocal
=a+9*1/2
reduce the expression"a"
=a+9/2
find the product
answer is a+9/2
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

Question #1:
Select all the statements that are true of a least-squares regression line.
The regression line maximizes the residuals between the observed values and the predicted values.
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 0The 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.

find two consecutive odd integers such as that 6 times the lesser integer is 7 more than 5 times the greater integer
Answers
Answer:
The first consecutive integer is 17 while the second is 19
Step-by-step explanation:
Let us say that the first odd integer is x
At this point, the second odd integer will be x+2.
This is because to obtain the next consecutive odd integer, 2 will have to be added to the original number.
From the question, we can set up an equation as shown below:
[tex]6x= 7+5(x+2)[/tex]
from this, we can simply evaluate and find out the value of x
[tex]6x=7 +5x +10\\x=17[/tex]
therefore, the first consecutive integer is 17 while the second is 19

42.25 square inches
Step-by-step explanation:
the formula for area of a square is length x width
a square has four equal sides
so the length and width of the square are 6.5
so you would multiply 6.5 by itself: 6.5x6.5=42.25
so the tile overs 42.25 sq inch

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.
