Answer: About 4 points should be below the trend line.

Step-by-step explanation: A Scatter Plot has points that shows the relationship between two sets of data.

A line of best fit or trend line is a straight line that best represents the data on a scatter plot.

This line may pass through some of the points, none of the points, or all of the points.

But its objective is to have the line as close as possible to all points, and as many points above the line as below.

As there are 4 points above the trend line, so there should be 4 points below that.

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

5 because of two ways one you could do 6*what is 30. Or you could do repeated addition 30=5+5+5+5+5+5. But when you do 30=5-5-5-5-5-5. You are doing repeated subtraction which is equivalent to 30-5*6= 0.

Solve the equation 2x^2-3x-6=0 give your answer correct to two decimal places

IRISSAK [1]

Answer:

Step-by-step explanation:

2x² - 3x - 6 = 0

Using the quadratic formula

$x = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a}$

a = 2 , b = - 3 , c = 6

Substituting the values into the above formula

We have

$x = \frac{ - - 3± \sqrt{ { - 3}^{2} - 4(2)( - 6)} }{2(2)}$

$x = \frac{3± \sqrt{9 +48 } }{4}$

$x = \frac{3± \sqrt{57} }{4}$

$x = \frac{3 - \sqrt{57} }{4} \: \: \: \: or \: \: \: \: \: x = \frac{3 + \sqrt{57} }{4}$

We have the final answer as

Write the point-slope form of the equation of the line that passes through the points (6, 6) and (-6, 1). Include your work in y

Allushta [10]

Answer:

Step-by-step explanation:

you need the formula (y-y1) = m(x-x1) that uses a slope and a point

m=(y1-y2)/(x2-x1)= 6-1/6+6=5/12

now pic any poit out of the 2 given ones

Answer:

(y-6) =(5/12)(x-6)
