What is a Scatter Plot?Dots are used in a scatter plot to show the values of two different numerical variables. Each dot's location on the horizontal and vertical axes represents a data point's values. To view relationships between variables, utilize scatter plots.
The closer the data points come to forming a straight line when plotted, the higher the correlation between the two variables, or the stronger the relationship. If the data points make a straight line going from near the origin out to high y-values, the variables are said to have a positive correlation.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
Given data ,
Let the scatter plot represents the funds raised by a TV station since its first year of operations
Let the number of years be represented as x
Let the contribution be represented as y
where the values of x and y are
x = { 1 , 3 , 5 , 8 , 11 , 14 }
y = { 70000 , 150000 , 190000 , 230000 , 270000 , 290000 }
The scatter plot is graphed and the linear regression equation is
y = 15901.6x + 88688.5
Hence , the scatter plot for the contribution for x years is plotted

Which expression is a factor of 9r^2-4r+1
Answers
Answer:
There are no real factors for this.
Step-by-step explanation:
We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or
We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.
Let's use the 2nd approach.
Here, a = 9, b = -4 and c = 1.
Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.
Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.

The family car leaves the house 112 hours after the moving van and follows the same route. The moving van travels at an average speed of 45 miles per hour. The family car travels at an average speed of 60 miles per hour. After how many hours of driving will the family car catch up to the moving van?
Answers
Answer: 336 hr
Step-by-step explanation:
Given
The speed of the van is 45 mph
The speed of the family car is 60 mph
distance traveled by van in 112 hours is
[tex]d_1=45\times 112=5040\ miles[/tex]
After 112 hours family car started its Journey. Suppose, van travels another x miles after the family car started its Journey
So, distance traveled by the family car in 't' hours
[tex]\Rightarrow 60\times t=112\times 45+45\times t\\\\\Rightarrow 15 t=5040\\\\\Rightarrow t=\dfrac{5040}{15}=336\ hr[/tex]
So, after traveling 336 hr, the family car will catch the van

A box is to be wrapped in a shiny pink decorative paper. The box is 99 inches long, 55 inches wide, and 44 inches high. What is the minimum amount of decorative paper needed to cover the box?
Answers
Answer:
24442 square inches of decorative paper
Step-by-step explanation:
To solve for the above question, we have to find the Surface Area of the box. The box is shaped as a Rectangular Prism.
Hence, the formula is given as:
A = 2(wl + hl+ hw)
Where:
Length (l) = 99 inches
Width (w) = 55 inches
Height (h) = 44 inches
=2 × (55×99 + 44×99 + 44×55)
=24442 square inches
Therefore, the minimum amount of decorative paper needed to cover the box is 24442 square inches of decorative paper.

2.) mean: 69.4, median:63, mode:none
3.) none since they are numbers that can be high but not low.
4.)The outlier is a greater number like the mean is 69 and the median is 63 which is halfway between 63 and 64 it will affect more the mean than the median since it doesn't matter the actual value of the outlier. it just depends on what the outlier is.

A) Use the distance formula to find the length of each side, and then add the lengths.
B) Use the slope formula to find the slope of each side, and then determine if the opposite sides are parallel.
C) Use the slope formula to find the slope of each side, and then determine if the consecutive sides are perpendicular.
D) Use the distance formula to find the length of the sides, and then multiply two of the side lengths.

Answer: A
Step-by-step explanation:
We have to find the perimeter of the figure.
For doing so, we have to find the length of all the sides of a quadrilateral
The length of a line segment joining points (x1,y1) and (x2,y2) is given by the distance formula:
after finding length of all the sides, we add the length of each side to get the perimeter.
Use the distance formula to find the length of each side, and then add the lengths.

Answers
Answer: I’m pretty sure that BD should also be 150
Step-by-step explanation:
The measure of angle O is 75 because the angle is always half of the arc, so knowing that, and also cd and abs are congruent, the other side of o is probably the same as the other, so it’d be 75, multiply by 2 and itll be 150.

A coat has an original price of $48.99. Gloria wants to calculate the final cost of the coat including the 7% sales tax. She could use the expression 0.07 (48.99) + 48.99 to determine the final cost. Which other express could she also use to determine the final cost?
(0.07) ($48.99)
(1.07) ($48.99)
(1.93) ($48.99)
(0.93) ($48.99)
Answers
Ex
Since the first expression was
(0.07 x 48.99) + 48.99
Then multiply 0.07 by 48.99 =3.4293 + 48.99 = 52.4193
Try
1.(0.07)(48.99) =3.4293
2.(1.07)(48.99)=52.4193
3.(1.93)(48.99)= 94.5507
4.(0.93)(48.99)= 45.5607
