Suppose a scatter plot indicates that there is a positive linear association between two quantitative variables. Which of these statements MUST
be correct about the line of best fit for the data in the scatter plot?
Answers
Answer:
As the x increases, the y increases. The line will have a positive slope.
A Scatter Plot has points that show the relationship between two sets of data and the points are plotted on horizontal and vertical axes.
The statement about the line of best fit for the data in the scatter plot is the line must have a positive slope.
What is a scatter plot?A Scatter Plot has points that show the relationship between two sets of data. The points are plotted on horizontal and vertical axes.
We have,
A positive linear association between two quantities variables.
Positive linear association means:
If one variable increases as the other variable increases.
Negative association means:
If one variable increases and the other variable decreases.
No association means:
There is no relationship between the variables.
Thus the statement about the line of best fit for the data in the scatter plot is the line must have a positive slope.

The function h(x) is a transformation of the square root parent function, f(x)= sqrt x . What function is h(x) ?
Answers
Answer:
You can actually change it however you want I just happen to add two underneath the radical which shifted the graph to the left and I subtracted five on the outside of the radical which shifted the graph down five
The function h(x) is a transformation of the square root parent function, f(x)= √x then the function h(x) is√x+2 - 5
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
f(x) = √x
f(x) is a parent function.
a parent function is the core representation of a function type without manipulations such as translation and dilation.
We have to find the function h(x) which is obtained by transforming the function f(x)
From the given graph, the function f(x) is moved up about 2 units and the shifted left of 5 units
h(x) =√x+2 - 5
Hence, the function h(x) is a transformation of the square root parent function, f(x)= √x then the function h(x) is√x+2 - 5

of pairs of shoes ordered. Which of the following equations models this
proportional relationship? *
Answers
Answer:

Step-by-step explanation:
I don't have the choice of answers of what is being said as proportional but an example is here below of what numbers are multiples of 42 and therefore found its proportion this way.
10s = 420t (10 x 42)
9s = 378t (9 x 42) etc...
8s = 336t
7s = 294t

Find the slope- intercept form -5x+6y=30
Please show steps
Answers
-5x+6y=30
-5x+6x0=30
-5x+0=30
-5x=30
X=-6
Answer:
slope-intercept is 5/6x, y intercept is 5 and x intercept is -6
Step-by-step explanation:
-5x+6y=30
first you are going to move your thirty to the other side of the equation so your going to minus 30 from both sides.
-5x+6y(-30)= 30(-30)
-5x+6y-30=0
then move your y to the other side of the equation
-5x-30=6y
divide by 6 to get y alone
-5/6x -(30/6)=y
-5/6x-5=y
therefore your slope is 5/6x, your y intercept is 5 and your x intercept is -6
Sandra transforms a line segment such that the new image is longer than the original line segment. What type of transformation must the line segment have undergone?
A. dilation
B reflection
C rotation
E translation
Answers
In math, dilation is the enlarging or shrinking of a mathematical element. Dilation changes the size and position of a figure (because of the size difference) but not the shape!
The type of transformation must the line segment have undergone if Sandra transforms a line segment such that the new image is longer than the original line segment, is dilation, so option A is correct.
What is dilation?The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger.
Given:
Sandra transforms a line segment such that the new image is longer than the original line segment,
The above transformation is an example of dilation, as in dilation the image can be transformed into a large image or a small image,
Thus, the given transformation is an example of dilation.

A down payment of $195 is made on a television that costs $1300. What percent of the
cost is the down payment?
Answers
Answer:
15%
Step-by-step explanation:
Add 195 to 1300, which gives you, 1495.
Use the formula for percent change: Difference = % * original price.
So what is the difference between 1495 and 1300? It’s 195.
Now we have 195 as the difference.
Do we know the original price of the TV? Yes we do. What is it? Its 1300 because the question states the TV costs $1300.
Now we have the equation 195 = % * 1300
We don’t know the percentage, right? So now we have to solve for %. To do that, you have to do 195 divided by 1300, which gives you 0.15. Lastly, you have to turn 0.15 into a percentage, to do that, multiply 0.15 by 100, and it should give you 15%.
Therefore, 15% is the down payment. Hope this helps!

The area of a bulletin board is 90 ft. The length is nine feet less than four times the width. Find the length and the width, in feet, of the bulletin board.
width
ft
length
ft

Answers
Width = x
Length = 4x - 9
A = L*W, so the equation is:
x(4x - 9) = 90
Solve:
4x^2 - 9x = 90
4x^2 - 9x - 90 = 0
(4x + 15)(x - 6) = 0
4x + 15 = 0
4x = - 15
x = -15/4
^^^ reject because distance can’t be negative
x - 6 = 0
x = 6 ft (width)
Length = 4x - 9
L = 4(6) - 9
L = 24 - 9
L = 15 ft
Check:
A = L*W
90 = 15 * 6
90 = 90
Answer: The length is 15 feet and the width is 6 feet.

Answer:
(- 3, 0 ) and (5, 0 )
Step-by-step explanation:
To find the x- intercepts let f(x) = 0 , that is
x² - 2x - 15 = 0
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (- 2)
The factors are - 5 and + 3 , since
- 5 × 3 = - 15 and - 5 + 3 = - 2 , then
(x - 5)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 3 = 0 ⇒ x = - 3
The x- intercepts are (- 3, 0 ) and (5, 0 )
