The distance is the addition of all sides of the figure. Then, we need to find the length of the diagonal (d). To do that we have to make a right triangle with height (h) = 5 m. Given that the top length is 12 m and the bottom length is 15 m, the base (b) of the triangle is 15 - 12 = 3 m.
Using Pythagorean theorem:
d² = h² + b²
d² = 5² + 3²
d = √34
d = 5.8 m
Therefore, the distance he will have walked is 5.8 + 12 + 15 + 5 = 37.8 meters
A residual values should be equally and randomly spaced around the horizontal axis. If the plot looks like any of the images in C and D, then the data set is probably not a good fit for regression. A non-linear pattern is more appropriate.
M=(y2-y1)/(x2-x1)= (3-1)/(4-3) =(2/1)= 2 y=mx+b. plug in one of the points for the second line and solve for b 1=2(3)+b 1=6+b -5=b plug b and m back into the equation y=mx+b y=2x+-5 The solution to the system must make sense when plugged into both equations C works because y=x+3; 11=8+3 11=11 and y=2x-5; 11=2(8)-5 11=11
