Kevin gathered data from his classmates about the number of books they consulted and the total time they spent on a research paper. The scatter plot shows the data he gathered and the line of best fit.
The equation of the line of best fit is y = 70.28x + 425.77.
Based on the line of best fit, approximately how many minutes would a student who consults 3 books spend on a research paper?
211
372
496
637
The student who consults 3 books spends 637 minutes on a research paper based on the line of best fit if the equation of the line of best fit is y = 70.28x + 425.77 option (D) is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
We have:
Kevin gathered data from his classmates about the number of books they consulted and the total time they spent on a research paper.
The line of best fit is:
y = 70.28x + 425.77
Plug x = 3 in the line of best fit:
y = 70.28(3) + 425.77
y = 21.084 + 425.77
y = 636.61 minutes ≈ 637 minutes
Thus, the student who consults 3 books spends 637 minutes on a research paper based on the line of best fit if the equation of the line of best fit is y = 70.28x + 425.77 option (D) is correct.

Answer:
127 degrees
Step-by-step explanation:
If <1 is 53 degrees, then its vertical angle is also 53 degrees. Same side interior angles are supplementary which means they add up 180 degrees.

If we already know that XY=WZ, which additional fact would prove that quadrilateral WXYZ is a parallelogram?
Answer:
WX=ZY would prove that the quadrilateral WXYZ is a parallelogram
Step-by-step explanation:
The additional fact that would prove that quadrilateral WXYZ is a parallelogram is '' XY = YZ''.
Given
If we already know that XY=WZ,
What is parallelogram?A Parallelogram is a four-sided quadrilateral whose opposite sides are parallel and congruent to each other.
The opposite angles of a parallelogram are equal.
These bisectors intersect each other at 90 degrees.
And it means that they are perpendicular.
Since they are perpendicular, we find that there 4 congruent triangles, XY is parallel to WZ, and WX is parallel to YZ.
Additionally, opposite angles are equal.
These two latter findings are the characteristics of the parallelogram.
Hence, the additional fact that would prove that quadrilateral WXYZ is a parallelogram is '' XY = YZ''.

On a game show, Celine is given the digits from 1 to 6 and has to use them to fill in a row with 2 spots. If the number formed is the correct price of the item displayed, she wins the item. Given that each digit can be used only once, how many 2-digit prices are possible?
Answer:
30 Two digits prices are possible.
Step-by-step explanation:
Celine was given numbers from 1 to 6
so the possible numbers are 1, 2, 3, 4, 5, 6
And we need to make a two digit number using these digits by using them only once
Using the box method of permutation
We have 6 possibilities on the tenth place of the two digit numberOn the One's place we will have 5 choices of numbers as one among these six given digits is used on the tenth place (Non repeating)So we will have total permutations = 6*5 = 30
Therefore 30 Two digits prices are possible.

what is the quotient of 6 1/4 ÷ (-5/8)
Answer: -10
Step-by-step explanation:
1. Convert 6 1/4 to an improper fraction
25/4
2. Find the quotient using the keep, change, flip method
- Keep the first fraction (25/4)
- Change the division sign to a multiplication sign
- Flip the second fraction (i.e. find the reciprocal)
-5/8 -> -8/5
3. Multiply and solve by multiplying the numerators and denominators together respectively
25/4 * -8/5
25*-8 = -200
4*5 = 20
-200/20 = -10

graph y=3/4x-4 ....……………
The required graph is shown below that represents equation y = (3/4)x - 4.
The equation y = (3/4)x - 4 represents a linear function in slope-intercept form, where the coefficient of x is the slope of the line and the constant term (-4) is the y-intercept.
To graph the equation y = (3/4)x - 4, follow these steps:
Start by plotting the point (0, -4) on the y-axis. This is the point where the line intersects the y-axis.
Since the slope is 3/4, it means that for every 4 units moved to the right along the x-axis, the corresponding y-value moves up 3 units.
From the y-intercept (0, -4), move 4 units to the right and then 3 units up to find another point. This gives us the point (4, -1).
The two points (0, -4) and (4, -1), draw a straight line passing through both points. This line represents the graph of the equation y = (3/4)x - 4.

The cost of a cheese pizza is $9.99 plus $0.35 for each additional topping, t .
Write an inequality that can be used to represent the cost of a pizza that is at most $12.
What is the most number of toppings that a pizza can have and still be at most $12?
Step-by-step explanation:
$9.99 + $0.35t <= $12
$0.35t <= $2.01
t <= 5.74
The most number of toppings would be 5.
Answer:
9.99 + 0.35t ≤ 12
5 toppings
Step-by-step explanation:
First part of question:
9.99 + 0.35t ≤ 12
"At most" means you use ≤.
Second part of question:
Take the inequality and solve for t:
9.99 + 0.35t ≤ 12
0.35t ≤ 2.01
t ≤ 5.74
So, the most number of toppings that a pizza can have and still be at most $12 is 5 toppings. You have to round down 5.74 to 5 otherwise the cost will exceed $12.
