Answer:
12.3
Step-by-step explanation:
(a) How would you characterize the relationship between the hours spent on homework and the test scores? Explain
For this case what we see is that we have a scatter diagram, which we can model using a linear trend defining the following variables:
x: number of hours studied.
y: test scores.
The linear relationship would be of the form:
y = mx + b
(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework?
y = 8x + 40
For three hours of study we have that the note would be approximately:
y = 8 * (3) + 40
y = 64
(c) What does the number 40 in Part (b) mean in the context of the situation?
The number 40 means that if you do not devote any study time, then you expect the test score to be 40.
Answer:
162 inches.
Step-by-step explanation:
Please consider the complete question.
Carlos is helping his grandmother make a rug. They have 5 yards of fabric, which is equal to 180 inches. They need an additional of 4 1/2 yards of fabric to finish the trim. How many inches are in
yards?
Let us convert
into improper fraction as:

Now, we will use proportions to solve our given problem as:



To find number of inches in 9/2 yards, we will multiply 9/2 by 36 as:



Therefore, there are 162 inches in
yards.
Answer:
D. (0, 0), (0,3), (-3, 3), (-3, 0).
Step-by-step explanation:
From the statement we know that the vertices of the triangle are:
(0,0) , (0, 3) , (3, 3) , (3, 0).
By multiplying the vertex matrix with the reflection matrix
we create a reflection image in the y-axis.
So the result is letter D. (0, 0), (0,3), (-3, 3), (-3, 0).
Answer:
Hello!
There are multiple ways to tell a line from anything else, (segment, ray ex.)
A line never truely ends, and it is ALWAYS straight.
If it's:
~ Not straight
~ Has dots at ends
Then it's not a line
If it doesn't end, and is straight, then chances are, it is a line.
Take a look at the chart I have attached for different types of lines.
I hope this helped you, and have a great day!!!
