Answer: when looking at the graph, anything that is going down is decreasing and anything that is going up is increasing. Maybe that can help you.
Step-by-step explanation:
Answer:
x=5
y=4
Step-by-step explanation:
Step 1:
Let us solve for <em>x</em> using the 
equation by <u>isolating terms containing the variable</u>:
Great! <em>x</em> is 5... let's find <em>y</em>.
Step 2:
Since we know the value of <em>x</em>, we can use what we know to find <em>y</em> using the <u>other equation</u>:
<em>Given that x=5, we can </em><u><em>replace</em></u><em> x with 5</em>.
<em>I hope this helps! Let me know if you have any questions :)</em>
Answer:
(2, 10)
Step-by-step explanation:
Making the points on a graph and creating a line between them, you can see the equation to connect the two points is -3x + 16. Then, because the points are 5 units apart horizontally, go to the point that is 4 units left of point T (1/4 of the way between T and S) and that is your point: (2, 10)
I apologize if this is incorrect :)
Answer:
Dependent sample: The same textbook are being compared.
Step-by-step explanation:
We are given the following in the question:
A student wants to compare textbook prices for two online bookstores.
Sample 1 from bookstore A:
$115, $43, $99, $80, $119
Sample 2 from bookstore B:
$110, $40, $99, $69, $109
Dependent and independent sample:
- Dependent samples are paired observations for same set of items.
- Independent samples are observations made on two different sets of items.
- If the values in one sample affect the observations in the other sample, then the samples are dependent.
- If the values in one sample have no effect about those of the other sample, then the samples are independent.
Thus, the given sample is dependent sample as the same textbook is being compared from two different bookstore.
