This is a very simple and easy problem. I'm not sure why you need someone else to solve it, but I hope this helps
a. Linear equation:
Let x be amount of movies rented
$8 + ($2.50 * x)
b.
$8 + ($2.50 * 10)
= $8 + $25.0
= $33
<h2>
Hello!</h2>
The answer is:
The second option,
<h2>
Why?</h2>
Discarding each given option in order to find the correct one, we have:
<h2>
First option,</h2>
The statement is false, the correct form of the statement (according to the property of roots) is:
<h2>
Second option,</h2>
The statement is true, we can prove it by using the following properties of exponents:
We are given the expression:
So, applying the properties, we have:
Hence,
<h2>
Third option,</h2>
The statement is false, the correct form of the statement (according to the property of roots) is:
<h2>
Fourth option,</h2>
The statement is false, the correct form of the statement (according to the property of roots) is:
Hence, the answer is, the statement that is true is the second statement:
Have a nice day!
Answer:
2. reflect parrellelogram ABCD across the x-axis and dilate the result by a scale factor of two centered at the orgigin
Step-by-step explanation:
to correctly map the parallelograms together you need to dialate the shape, because we already know that its two times bigger
Answer:
a)Slope:
Intercept:
b)
And the determination coeffecient is
Step-by-step explanation:
Data given and definitions
The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
When we conduct a multiple regression we want to know about the relationship between several independent or predictor variables and a dependent or criterion variable.
n=110,
Part a
The slope is given by this formula:
If we replace we got:
We can find the intercept with the following formula
We can find the average for x and y like this:
And replacing we got:
Part b
In order to calculate the correlation coefficient we can use this formula:
For our case we have this:
n=110,
So we can find the correlation coefficient replacing like this:
And the determination coeffecient is
Answer:
Step-by-step explanation:
<em>The question in English is</em>
If 4x= 5/6y then 5y=
we have
Solve for 5y
Multiply both sides by 6
