A. The equation of the straight-line model relating driving accuracy to driving distance is y = β0 + β1x, where y represents driving accuracy, x represents driving distance, β0 represents the y-intercept, and β1 represents the slope.
B. Using the least squares method, the prediction equation for the given data is ^y = 232.4 - 0.7639x, where ^y represents the predicted accuracy for a given distance x.
C. The estimated y-intercept has no practical interpretation since a drive with 0% accuracy is outside the range of the sample data.
D. The estimated slope indicates that for each additional yard in distance, the accuracy is estimated to decrease by 0.7639%.
E. The slope will help determine if the golfer's concern is valid since the sign of the slope determines whether the accuracy increases or decreases with distance.

Find the slope!! Please
Answer:
The slope is -(1/3)
Step-by-step explanation:
For every 3rd step, the y-value decreases by 1 and the line intersects the y-axis in (0,1).
This observation yields the following equation for your line:
f(x) = y = -(1/3)x + 1
Therefore, the slope is -(1/3).
Use the graph of the polynomial function to find the factored form of the
related polynomial. Assume it has no constant factor.
A. (x + 1)(x-7)
B. (x + 1)(x + 7)
C. (x - 1)(x-7)
D. (x - 1)(x + 7)
The factored form of the related polynomial function is (x - 1)(x - 7).
What is polynomial function ?Polynomial function is a function that involves non-negative integer powers or positive integer exponents of a variable in an equation like the quadratic equation, cubic equation.
We have,
In the graph given in question, we can see that x - intercepts the axis twice.
And graphs behave differently at various x - intercepts. Sometimes the graph will cross over the x-axis at an intercept and other times the graph will touch the x-axis and bounce off.
Now, in graph;
The intercept at x = 1 ,
i.e. the solution of the x - 1 = 0 and passes through the axis.
Now,
The x - intercept at x = 7, is the solution of x - 7 = 0 and again passes through the axis.
So, from the above statements we can say that the factored form of the related polynomial is (x - 1)(x - 7)
Thus, we can say that the factored form of the related polynomial function is (x - 1)(x - 7).

Answer:
C. 2x = 100
Step-by-step explanation:
Vertical angles are 2 angles which are vertical and have the same degree. For example, if an angle which is vertical to another is 80°, the other angle is 80° too. The reason why you can't say it's 50 is because they want you to identify the equation of it, so you can't really like shortcut through and you need to make an answer for explanation. Hence 2x = 100 is the best answer.

Given that 3 apples and 4 pears cost $1.95, 4 pears and 1 orange cost $1.60, and 1 orange and 3 apples cost $1.15, what is the cost of 1 apple?
Answer:
Step-by-step explanation:
Given that 3 apples and 4 pears cost $1.95, 4 pears and 1 orange cost $1.60, and 1 orange and 3 apples cost $1.15, what is the cost of 1 apple?
Let us represent
Number of apples = x
Number of pears = y
Number of oranges = z
Given that
3 apples and 4 pears cost $1.95
3x + 4y = 1.95
4 pears and 1 orange cost $1.60
4y + z = 1.60
z = 1.60 - 4y
1 orange and 3 apples cost $1.15
z + 3x = 1.15
z = 1.15 - 3x
what is the cost of 1 apple?

Find the sum. Write your answer in simplest form. - 4 1/6 + 5 4/7
Answer:
1 17/42.
Step-by-step explanation:
Find the common denominator, which is 42.
So change -4 1/6 to -4 7/42.
And change 5 4/7 to 5 24/52.
So add -4 7/42 + 5 24/52 and you'll get: 1 17/42.

Tres hermanos van a repartirse un pastel y medio, cuanto le toco de pastel a cada uno de los hermnos
Answer:
medio pastel cada uno
Step-by-step explanation:
Hay 3 hermanos, si decimos que un pastel entero tiene 6 pedazos entonces su fraccion seria 6/6. Si dividimos este pastel entre los tres hermanos cada uno tendria...
[tex]\frac{6 / 3}{6}[/tex] = [tex]\frac{2}{6}[/tex]
Medio pastel seria la mitad de 6/6 que seria 3/6. Si dividimos esto entre los 3 hermanos cada uno tendria...
[tex]\frac{3 / 3}{6} = \frac{1}{6}[/tex]
Ahora que dividimos los 2 pasteles tenemos que unir las fracciones para saber cuanto pastel le toco a cada hermano...
[tex]\frac{2}{6} + \frac{1}{6} = \frac{3}{6}[/tex] o medio pastel cada uno

Answer:
[tex]-\frac{16}{3}[/tex]
Step-by-step explanation:
This is simple multiplication. To make this easier to solve, let's modify the fraction so it looks like this:
[tex]-8*2*\frac{1}{3}[/tex]
You could also change it to this:
[tex]\frac{-8}{1}*\frac{2}{3}[/tex]
Do these look simpler? Hopefully they do!
Now, let's multiply the numerators. When multiplying fractions, we multiply numerators and denominators separately. Here, that means we could, taking both paths, do this:
[tex]\frac{1}{3}(-8*2)[/tex]
[tex]=\frac{1}{3} (-16)[/tex]
[tex]=\frac{-16}{3}[/tex]
[tex]=-\frac{16}{3}[/tex]
Or we can do this:
[tex]\frac{-8}{1} *\frac{2}{3}[/tex]
[tex]=\frac{-8*2}{1*3}[/tex]
[tex]=\frac{-16}{3}[/tex]
[tex]=-\frac{16}{3}[/tex]
But what if the denominator of one fraction has a common factor with the other number or the other fraction's numerator? We would find the common factor, and cancel it out to simplify. We could do this before multiplying, during the multiplication, or after multiplying.
In the case of a number times a fraction, it could also be seen as division, as fractions are essentially that: one number divided by another, except we aren't using the decimal.
I hope this helps you understand, so you don't need to ask this again! It's about 8:00 AM where I am as I'm writing this answer, so good morning and have a wonderful day!
The equivalent value of the fraction is A = -16/3
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first fraction be represented as p
Let the second number be represented as q
Now , A = pq
when the value of p = 2/3
And , when the value of q = -8
On simplifying the equation , we get
A = ( 2/3 ) / ( -8 )
So , the left hand side of the equation is equated to the right hand side by the value of ( 2/3 ) / ( -8 )
A = ( 2/3 ) / ( -8 )
A = ( -8 x 2 ) / ( 3 )
On simplifying , we get
Multiply by -8 on the fraction , we get
A = ( -8 x 2 ) / 3
A = -16/3
Therefore , the value of A = -16/3
Hence , the fraction is A = -16/3
