Which step comes last when using the divide-center method to find the trend line on a scatterplot?

Connect the two centers to produce the trend line

Step-by-step explanation:

When the dots have been plotted, there are three steps to find the trend line on a scatter plot:

1.  Draw a vertical line that separates the full set of points into two sets, each with the same number of dots.

2.Mark with a special sign (e.g + or ×) the middle value in each of the two sets obtained in the previous step.

3.Join the two marks mentioned in the step (2) with a straight line, and extend it to the edges of the graph. This line is the trend line, and this is the last step.

Thus, the last step when using the divide-center method to find the line on scatter plot is Connect the two centers to produce the trend line.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
