Answer:

Option D is correct.

y = \frac{81}{2}x-\frac{160,069}{2}

Step-by-step explanation:

The equation of line of best-fit for this scatter plot is given by:

y=mx+b

where, m is the slope and b is the y-intercept.

As per the statement:

The enrollment at East Valley High School over a six-year period is displayed in the scatter-plot.  

Student Enrollment at East Valley High School

Here, x represents the number of years and y represents the number of students.

Enter the values of x into one list and the values for y into the second list.    

You can see the graph of the scatter plot as shown below in the attachment.

we get, the equation of line is:

y = 40.57x-80182

or we can write this as:

y = \frac{81}{2}x-\frac{160,069}{2}

Therefore, the  equation of the line of best-fit for this scatter plot is:

y = \frac{81}{2}x-\frac{160,069}{2}

What are the zeros of f(x) = x2 + x - 20?
jeyben [28]

Answer:

x = - 5, x = 4

Step-by-step explanation:

Given

f(x) = x² + x - 20

To find the zeros equate f(x) to zero, that is

x² + x - 20 = 0

Consider the factors of the constant term ( - 20) which sum to give the coefficient of the x- term ( + 1)

The factors are + 5 and - 4, since

5 × - 4 = - 20 and + 5 - 4 = + 1, hence

(x + 5)x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 4 = 0 ⇒ x = 4

Which of the following are possible values of r?<br><img src="https://tex.z-dn.net/?f=%20%7Br%7D%5E%7B2%20%7D%20%20%3D%20%20%5Cf
marshall27 [118]

Answer:

r=\frac{\sqrt{3} }{4}    and    r=-\frac{\sqrt{3} }{4}

Step-by-step explanation:

when you solve for r in the given equation, you need to apply the square root property, which gives positive and negative answers (both should therefore be considered):

r^2=\frac{3}{16} \\r=+/-\sqrt{\frac{3}{16}} \\r=+/-\frac{\sqrt{3} }{4}

then you need to include these two possible solutions:

r=\frac{\sqrt{3} }{4}    and    r=-\frac{\sqrt{3} }{4}
